5 Ways an HVAC Monitoring System Can Save You Money

HVAC equipment accounts for a significant portion of a manufacturing facility or building’s energy consumption and operating costs. HVAC monitoring systems can help to lower these expenditures by continuously monitoring the environmental conditions. They also keep tabs on the efficiency of the machinery for heating, ventilation, air conditioning, and refrigeration.

The systems notify the staff in real-time, particularly after hours, when there are any problems or inefficiencies. Personnel is therefore able to cope with power outages and disasters right away and fix equipment with minimal adjustments rather than extensive repairs. However, remote monitoring systems can also be used in other useful ways that can result in cost savings.

1. Controlling The Temperature

Accurate control of temperatures is crucial to various chilled water applications; an HVAC monitoring system offers impeccable control over temperatures. Remote monitoring devices make it easier to check the temperatures of air conditioners, walk-in refrigerators, freezers, and boiler water.  It can also keep track of the ambient temperature in sensitive areas like laboratories and data centers. Customers will be informed right away if the temperature rises to dangerous levels.

Extremely high or low temperatures consume more energy than is necessary and a good system will save energy costs. 

2. Preventing Chiller Failures

HVAC monitoring systems can record pressure, water temperature; pH, pump status, tank levels, and flow rate continually because it records data. Regularly examining the data log and reports will help you see any unusual patterns that could indicate a problem. Identifying these patterns might quickly prevent damage to components like compressors in the long run.

For instance, a drop in water pressure could be a sign of a problem with the equipment or design of the chiller. You can also get the details you need to modify the chiller during periods of high demand. You can be informed when water use is exceptionally high and make the necessary changes to meet demand.

Access to the data collected by HVAC monitoring systems is often provided by online dashboards. These dashboards provide a broad overview of what is occurring with your HVAC equipment. It is recommended to have one of these systems because they are so cost-effective and simple to install.

3. Improved Airflow

HVAC monitoring systems use the least amount of energy while enabling maximum control on airflow. By measuring the rate of airflow, you may gain a better picture of the condition of the environment as a whole. If you learn about a ventilation issue as soon as possible, you have more time to take action to prevent a total shutdown. In addition, you can save maintenance costs by taking care of small problems during regular business hours.

4. Fixing Water Leaks

There are numerous more possible water sources, besides a storm or a burst pipe, that could harm a building’s interior and equipment. For instance, it’s common for water leaks from clogged or cracked drains, traps, pans, or tubing to be undetected until harm has been done. These and other HVAC problems, such as damaged compressors, leaking humidifiers, defective evaporator coils, broken fittings, joints, and gaskets, can be alerted to by a remote monitoring system. With water-sensing ropes or spot detection sensors for specific problem areas, the devices may protect larger areas.

5. Avoiding Damage From High And Low Humidity

Condensation brought on by high humidity can eventually lead to corrosion and the breakdown of machinery and equipment. Additionally, it might cause the growth of hazardous mold, slick surfaces, and slippery flooring.

Low humidity might be detrimental as well. Static electricity discharges caused by it are persistent and can wear down and damage electrical equipment. Besides other computer parts, it also harms motherboards, RAM, hard drives, and CPUs. A remote monitoring system will alert you any time the humidity falls beyond the desired range.

Data Center Cooling With Thermal Storage System

Data centres maintain several IT equipments that store, organize, process and disseminate significant amounts of data. These data centres require an uninterrupted power supply for the equipment to function accurately. This also means that it is important for data centres to have reliable cooling systems to prevent the temperature from rising which can lead to the failure of critical electronic equipment. So, if and when there is a power outage, stored chilled water in large buffer tanks provides continuous operation of the cooling system whilst the generator backup power supply cuts in.

As data center power and heat density increase, transient losses of electrical utility power potentially have more significant impacts and require special design considerations. Data centres these days use thermal storage tanks or chilled water buffer tanks in their cooling system to ensure that the equipment does not overheat the racks at the time when Grid power goes off and captive power kicks in.

There are several methods for increasing the resilience of Data Center cooling systems to counter power disturbances/switch from EB to Captive power & vice versa. Some data centers requiring very high power use standby generators for chillers. However, these add significantly to data center costs. Also, generators take several seconds to start up, after which it can take a few minutes to restart the chillers.

The other option is having a thermal storage tank and chillers with a quick start option. Thermal storage can extend the ability to cool data center IT equipment in the event of a power failure (till the captive power kicks in), by using thermal reserves to provide temporary cooling during a power outage.

VPF With Thermal Storage Concept:

Normal Scenario:
The pump will operate based on the field demand from DPT and the Bypass valve will run based on the chiller minimum flow value set.
The Thermal Storage tank will get bypassed by opening the main header valve. Hence, chiller(s) directly supply chilled water to load/field equipment.

During Power failure, Pump continues to circulate the water through chillers with the supply header motorized valve closed and the Thermal Storage Tank outlet valve kept open. Chilled water will be supplied from Thermal Storage Tank directly to the load/field equipment. The pump speed shall be modulated based on the field demand (from the DPT sensor).

It is therefore recommended to choose a system that is simple, reliable, and efficient that operates with normal Chillers, and provides a quick start when a power failure occurs. Chilled Water Thermal Storage System proves to be an effective solution for emergency supply of chilled water for data center cooling.

An additional Chiller will be switched ON for charging the Thermal Storage Tank based on water temperature. Once the chiller starts, the supply header valve and the tank return water valve will open. This will allow chilled water from the chiller directly to the load/field equipment and simultaneously, the Thermal Storage Tank will start to get charged.

Why Should You Consider A 4-Pipe System For Cooling And Heating?

Did you know that multi-function units are configured intelligently that can use waste heat and produce heating and cooling simultaneously and independently? This meets the objectives of Organizations looking out for technically feasible and cost-effective heating & cooling solution.

 In the recent past, organizations are switching from traditional two-pipe systems to four-pipe systems for meeting heating & cooling requirements. A construction that combines retail& offices, hospitals, hotels, etc might require cooling & heating at the same time. This unique set-up demands a highly flexible heating and cooling solution.

A traditional two-pipe system facilitates the entire building to be either heated or cooled. Though this system has been efficient, it’s not very flexible in today’s times. Modern buildings with large variations in the ambient temperature across various seasons might require cooling or heating or a combination of heating and cooling.

A four-pipe system offers separate supply and return lines for heating and cooling requirements. This means that heating and cooling can be provided simultaneously or independently, which increases flexibility, comfort level, and efficiency considerably.

With advanced algorithms controlling the system, it provides precise amounts of heating and/or cooling to all parts of the building at any given time.

It Consumes Less Energy

The combined system is much more energy-efficient, hence lower carbon emission, and saves costs than traditional systems that offer separate heating and cooling.  With lower energy consumption comes higher efficiency and hence lower operating costs.

Increased Demand For Cooling And Heating

As more and more buildings are getting into mixed usage segments, it’s clear that they will benefit more from simultaneous cooling and heating. With these shifting spectrums of various constructions, four-pipe systems have grown in popularity in recent years. With buildings being a combination of retail, hospitality & offices, and some being dedicated to residential use, there have been diverse load requests over the years. 

This combination might not be limited to just modern buildings. Older buildings are being retrofitted with four-pipe systems as well. The benefit of increased energy efficiency and lower operating cost makes it an economical investment. Climaveneta’s four-pipe system can provide a complete solution, with controllers and pumps for water circulation in the primary circuit.

Choosing Automatic Tube Cleaning System for Chillers

Did you know that your organization can achieve up to 10% energy savings through automatic tube cleaning systems?

Since chillers consume higher power in any commercial or institutional HVAC facility, smooth operations necessitate the use of an Automatic Condenser tube Cleaning System (ACCS) for increased efficiency, reduced energy consumption, and thereby lower operating costs.

An automatic tube cleaning system is essential for heat exchangers or chillers. They are specially designed to prevent common issues like rusting, fouling, and bioaccumulation in condenser tubes while keeping the chillers efficient and reliable for a longer time.

What are some of the problems that arise with cooling systems?
Water-based chillers are prone to fouling and scaling. This can reduce the heat transfer in the condenser tubes, resulting in increased energy consumption and reduced efficiency.

Furthermore, the use of harsh chemicals increases the maintenance cost and downtime of a chiller system. ACCS is the ultimate solution for preventing all of these issues and keeping condenser tubes clean.

How does the Automatic Condenser Cleaning System (ACCS) work?
Specialized & soft ACCS balls are designed for cleaning the tubes. These balls are injected at set intervals into the cooling water flow while monitoring the condition of the balls through the window of the ball collector. Under the force of water, ACCS balls travel along the mainline to reach the condenser tubes where the cleaning of internal tubes starts.

These tubes are cleaned by the scrubbing and wiping action of the ACCS balls, preventing any kind of buildup on the tube surface. After that, all the balls are routed to the ball trap and the system water runs through them as usual. These system balls then move to the ball collector where they are rinsed well and cleaned for the next ACCS cycle.

The Benefits of Installing an Automatic Condenser Cleaning System

• Improved Efficiency:
  ACCS prevents the accumulation of mud, scale, and biological fouling in the tubes that degrades the performance of the heat exchanger. It is also beneficial as it leads to lower energy consumption and operating cost reduction.
  
• The Increased Life Cycle Of Chillers:
  The ACCS runs automatically and cleans the tubes with specially designed ACCS balls regularly, preventing corrosion. The elimination of corrosion and fouling plays an important role in an extended condenser life.
  
• Eliminates Downtime:
  Advanced ACCS technology eliminates the downtime and maintenance costs for a chiller system. Since it works automatically, dependability on chemicals or manual cleaning is almost reduced to nil.
  
• Lower Water Treatment Costs:
  Various water treatments need to be carried out to prevent the scaling of ancillary equipment. With the ACCS system, you can save on the cost of chemicals used for water treatment.
  
• Environment Friendly:
  As the automatic tube cleaning system uses no harsh chemicals, it is an environmentally friendly option for the chiller system. Most of the maintenance techniques used for fouling mitigation use chemical inhibitors, which are not only expensive but also harmful to the environment.

From keeping a daily record of the chiller operation to using innovative maintenance solutions, organizations have to be adaptive towards latest technologies  for the systems to yield optimum efficiency and increase energy savings. With most organizations switching to greener technologies, ACCS is a good option as it provides automatic and eco-friendly process for the maintenance of chillers.

Chiller Acoustic Solutions by Climaveneta

Chillers are noise-producing equipment in a building and become more prominent when multiple chillers are installed. Installing effective noise control measures has become the order of the day, especially with specific guidelines and a very thin boundary existing between commercial & residential areas in some locations. Special care has to be taken for effective noise control depending on the installation site, ambient & surrounding conditions, without compromising the efficiency.

Climaveneta India offers low-noise version chillers to meet the required noise requirement level – be it Air Cooled or Water Cooled chillers.

Air Cooled Chiller Acoustic Solution

Fan and compressors, the moving parts, are the prominent noise-making items in chillers. The fan and air moving through the condenser coil also make noise. As fan blades cut through the air, they generate noise.

Compressors are also a source of noise generation. The compressor humming noise is caused by pulsating vibration, radiated as sound. We typically get tonal noise at the Mid and high-speed operations. To mitigate this issue Climaveneta provides an acoustic enclosure for the compressor to reduce the noise level. Due to the barrier, the compressor noise will be reduced by 4-5 dbA. Sometimes even higher.

Climaveneta has designed and manufactured solutions for reducing the noise level of condenser fans. These are basically low-pressure drop acoustic silencers that will easily provide access to the fans for maintenance purposes.

Overall noise level reduction with compressor sound attenuator and condenser fan attenuation will be 8 dbA approx.

Providing VFD fans is another way of reducing noise levels during nighttime running/low ambient/noise-sensitive applications.  Noise level reduction, during part loads, will be 3-4 dbA approx. There have been instances where the compressor – evaporator section is provided with acoustically lined panels. However, this might affect the air intake resulting in increased power consumption.

Water Cooled Chiller Acoustic Solution

For Water Cooled chillers, acoustic panels are provided with a structural framework with access for water piping connection, cable entries and operate the control panel. Noise level reduction is 8 dbA approx.  In case of any maintenance issue, the panels will have to be dismantled for easier access.

While the above methodology is implemented in fewer installations, a more common method is to provide acoustic insulation in the plant room.  This will also reduce the structural reverberations.

In most of the installations, water-cooled chillers are installed at the basement level to make use of the space, easier maintenance and reduce noise levels

The New Pillar of Infra: Data Centers Can Deliver More Computing Power While Improving Sustainability

Pandemic marked a pivotal point for many data centers and digital infrastructure providers; more was expected of them, and they were able to deliver. To meet the rising demand for computing power and digital services, data centers had to expand. Their demand has grown from a few megawatts to over 800 megawatts today. This is expected to double in the next 4-5 years. Mumbai & Chennai are considered hubs for DCs due to the existing infrastructure. NCR and Hyderabad are emerging hotspots due to the policies concerning data infra.

Many new data centers are being built today at a location where customers can rent and share space as well as computing power. New technologies like 5G mobile networks, artificial intelligence (AI), and high-performance computing have increased data centers demand. However, meeting this demand is just the tip of the iceberg.

Customers, as well as government and industry regulatory bodies, put constant pressure on data centers  to deliver more and demand less. Data  centers  today are under constant pressure to increase computing power while using less energy and reducing their carbon footprint. While this will be a pillar of the Indian economy in the coming years, India has a unique opportunity to learn from other countries’ experiences. Designers, DC providers, regulatory bodies, and suppliers will bear a significant amount of responsibility in this regard. Cooling systems’ efficiency and effectiveness are the solution to the dilemma of reducing data  center energy consumption while maintaining sustainability.

Data Center Trends

Adopting Best Cooling Practices:
Back in the day, traditional air-cooling systems could keep a safe, controlled environment for low rack densities of 2 kW to 5 kW per rack. Today’s operators, on the other hand, aim for densities of up to 20 kW, which are beyond the capabilities of traditional air-cooling systems. Modern cooling systems, such as rear door heat exchangers, PAC, and liquid cooling, maybe a good fit. Chillers can now operate at chilled water temperatures of up to 22 degrees Celsius, and this limit is constantly being pushed.

Plugging Into the Smart Grid:
There are ways to make your data center more efficient while maintaining sustainability, thanks to daily innovations and technological advancements. Smart grids create an automated power delivery network by allowing energy and information to flow in both directions. Operators of data centers can draw clean power from the grid and integrate renewable energy sources, making them occasional power suppliers.

Minimizing unused IT Equipment:
Distributed computing, which combines several computers into a single machine, is a great way to reduce unused IT equipment. By combining the processing power of multiple data centers, they can increase processing power while eliminating the need for separate facilities for different applications.
More effort must be put into designing data centers that address cooling, energy consumption, and waste to create truly green data centers that are beneficial to the environment.

● Installing energy-efficient servers
● Opting for more effective cooling solutions
● Optimizing hardware refresh cycles

Focusing on these key areas can help the global IT industry achieve, if not exceed, the reduction in carbon footprint that cloud computing has enabled.
The industry is at an inflexion point and it is a golden opportunity to establish this foundation and the latest trends and best practices.

Why Does Hospital Temperature Matter?

A hospital is considered to be a safe place that contributes to the well-being of patients and prevents the spread of disease. Hence, maintaining comfortable temperature and humidity, along with maintaining a clean, germ-free environment must be given special attention in this sector. The temperature, humidity levels, and good ventilation can affect the equipment and procedures in operating rooms, isolation rooms, and other sensitive areas within the hospital. A proper HVAC system allows for the right temperature, humidity control, filtration, ventilation, and energy efficiency. 

Filtration and Indoor Air Quality

Filtration and indoor air quality is critical for infection control. Premium filters remove minute particles in the air and other devices can be used to control virus. Advanced filtration & ventilation systems prevent cross contamination within and between operating rooms, isolation rooms, and other areas that require clean and safe air for patients and staff alike. The HVAC system is also required in the hospital to filter outflow air so that there isn’t any airborne transmission outside of the facility or a sick patient’s room.

Hospital Ventilating Systems

Hospital HVAC systems are responsible for an adequate level of fresh air supply that must be circulated for proper air flow. In regards to the air flow of hospital facilities and individual patients’ rooms, the pressure relationships need to be kept in mind. The positive pressure is maintained to protect  against inflow of any external or unclean air. Negative pressure on the other hand, restricts air flow to other areas from contaminated areas, preventing the spread of airborne transmission of disease.

Temperature and Humidity Controls

Often, temperature and humidity are linked to comfort level; but in a hospital, temperature and humidity can affect the healing process too. Humidity levels in a hospital are essential for infection control and may affect the rate at which a patient heals. Compared to other traditional commercial facilities that maintain room temperature, hospital HVAC systems must work extra hours to provide different temperatures for different parts of the facility. Sensitive testing and research equipment requires certain temperatures to operate  for proper functioning. Operating rooms generally require a lower set temperature than other rooms. 

Energy Efficiency in Hospitals

HVAC systems contribute to a big part of hospitals’ energy usage. Regular maintenance with proper operation can reduce energy consumption and hence operating costs. All system and equipment upgrades maximize energy efficiency, cut energy costs and hence save money.

Climaveneta has had numerous opportunities to assist and help ensure  energy efficiency for chillers in the hospitals. The HVAC solutions by Climaveneta have been designed to match  the specific requirements of the hospital – say chilled water & hot water needs. 

Climaveneta’s chillers/Heat Recovery Systems/Heat Pumps is specifically designed to operate at very high levels of efficiency at both full and partial loads.

Drive Customers In And Odours Out..Is Your Restaurant Properly Pressurized?

In today’s world, where presentation, ambience, service and vibes are all significant factors in the catering sector, it’s critical that your restaurant and kitchens smell great! The sense of smell can influence a customer’s opinion about whether a restaurant is good, awful, or indifferent, and, of course, whether or not to stay. Newer or even well-maintained HVAC systems can significantly increase ventilation by bringing clean air and neutralising smelly particles in the air. So, having stated that, is it time to upgrade your restaurant’s HVAC systems?

What Is A Restaurant HVAC System?
A commercial heating, ventilation, and air conditioning system in restaurants regulates the temperature inside the premises and improvement in air circulation & ventilation in other areas.

But Why Are These Restaurant HVAC Systems So Important?
HVAC systems are an essential component of many business buildings, including restaurants. play an important role in ensuring high indoor air quality, providing a luxurious experience for guests, improving working conditions in the kitchen, and more. Restaurants that fail to maintain their HVAC system properly might lose business if external environmental odours enter their facility and kitchen smell enters the service area.

Don’t Let Your Customers Take Kitchen Odors Home
Yes, the aroma of good food can entice people to enter your restaurant, but sometimes unwanted kitchen odours escape, leaving customers smelling like the kitchen long after they’ve left.

What is causing this?
Most of the time, it is a problem with air not travelling to kitchen hoods. Because the air isn’t travelling to the kitchen hoods, underlying air from the kitchen can seep into the dining area in some circumstances. This is caused due to the problems with building pressurisation. Exhaust hoods and makeup air units keep food odours from the kitchen from entering the dining area, producing a more pleasant environment for both guests and employees.

Get The Right Smells in the dining area:
People rely on their sense of smell to make decisions. Bad odours, according to customers, indicate a filthy kitchen and dining room. According to research, every negative review of a restaurant gets shared with others which will be an impediment to doing business. An upgraded or newer HVAC system will improve ventilation & filtration while also improving air quality in your restaurant, Creating a better environment for both diners and employees.

Professionally installed HVAC systems facilitate managing temperatures remotely while maintaining a balance between comfortable air temperatures and optimizing utility bills. Energy efficiency and cost-cutting features are also crucial to the long-term viability of a business.
