Why HVAC Experts Recommend Energy-Efficient Air Handling Units (AHUs) For Sustainable and Effective Management of Air Quality in Large Spaces

GUIDE TO CHOOSING ENERGY-EFFICIENT AIR HANDLING UNITS (AHUS) FOR SUSTAINABLE AND EFFECTIVE MANAGEMENT OF AIR QUALITY IN LARGE COMMERCIAL AREAS

According to one recent estimate, the world’s population may reach 8.5 billion in 2030 and 9.7 billion by

Reaching net zero goals will be difficult given this rate of population expansion. Many nations are going through an energy-intensive period of commercialization and urbanization, specifically driving growing demand for energy services. When we add the issues of combating climate change, energy saving becomes a critical goal for all business enterprises.

Energy is squandered in business enterprises in several ways. For instance, inefficient appliances waste energy in the commercial sector, and extra heat produced during peak occupation hours could be put to better use. Because there are few easy and reasonably inexpensive ways to track and manage the energy used in buildings and businesses, enormous amounts of energy are lost every day.

A meticulous inspection of any commercial building is required to design solutions to properly manage several parameters like air quality and humidity to maintain appropriate temperature and air quality in large open spaces. Depending on specific business needs, HVAC experts offer several solutions to improve occupant safety, comfort, productivity, structural preservation, and increased energy efficiency.

VENTILATION AND COOLING CHALLENGES IN LARGE COMMERCIAL COMPLEXES

Large entrances, insufficient insulation, air leakage, and inefficient heat distribution are all factors in energy loss in large buildings. Excessive outside air penetration makes buildings more susceptible to high energy expenses. Even in enclosed large areas, creating the proper air distribution (also known as thermal stratification) is challenging. Warm air rises, whereas cold air tends to settle, creating stratified layers prone to stagnation. In addition, cold downdrafts frequently arise along vertical surfaces due to temperature differences. These may result in unwelcome cold areas in the structure. By bringing in a lot of cold air at once, conventional HVAC cooling systems can make the issue worse.

Another factor is the variation in fresh air needs as per occupancy levels in different parts of a large facility. When the building is completely occupied, additional air may be required to meet the structure’s needs for fresh air. Hence, it is crucial to design the HVAC system when the requirement for air intake fluctuates so that these variations may be rapidly and readily addressed.

Finally, in large buildings, poor airflow, air stratification, and moisture accumulation can all work together to foster the growth of hazardous mold. In addition, stale air can be a thriving place for bacteria, viruses, and other airborne toxins to thrive.

Condensation of moisture is also common in large structures, especially those that are not insulated. Like all moisture concerns, this one could result in fungus growth troubles and structural damage to the building. Finally, in large buildings, poor airflow, air stratification, and moisture accumulation can all work together to foster the growth of hazardous mold. In addition, stale air can be a thriving place for bacteria, viruses, and other airborne toxins to thrive.

Troubleshooting ventilation and cooling issues can be challenging, particularly in buildings with several integrated HVAC components. It’s crucial to identify the root cause of any issues your building has if you’re encountering these or other similar issues. Energy-smart HVAC solution experts can help resolve most of these issues by using innovative solutions, significantly improving the affected buildings’ comfort, safety, productivity, and energy savings.

AIR HANDLERS CAN EFFICIENTLY MANAGE COMPLEX VENTILATION AND AIR PURIFICATION NEEDS OF VAST AREAS

One of the most efficient ways to manage the proper ventilation requirements for purifying and rejuvenating the interior air in a building is using an air handling unit, often known as an AHU. An essential part of any sizable air-cooling system, AHU allows simultaneously cooling vast areas while also assisting in regulating indoor air quality (IAQ). The system is fixed to a building’s ground floor, basement, or roof during installation.

By regulating temperature and airflow across different parts of a commercial complex, an AHU installation ensures that the occupants receive fresh air with comfortable cooling. AHUs are used frequently in conjunction with other heating and cooling systems. These units are often large and attached to ducts that distribute regulated air throughout the structure and expel exhausted air.

HOW AIR HANDLING UNIT (AHU) WORKS

An AHU unit is made up of components mounted in sizable, easily accessible box-shaped units called modules. These modules contain the necessary ventilation components for cleaning, cooling, or replenishing the indoor air in a location. Air handling devices pull outside air, clean it, and distribute it throughout the rooms. They can also pull indoor air that has been “recycled.” Several filters trap particles, viruses, bacteria, odors, and other air contaminants.

The AHU lowers the energy needed for air cooling since the exchanger mixes internal and outdoor air, lowering the temperature contrast when the air enters the coil and leading to lower energy consumption. The fans can operate as per the required flow rate thanks to the equipment’s variable regulation, which reduces consumption. Coils, heat exchangers, and other components are all optimized to provide the lowest pressure drop to achieve the highest efficiency, resulting in extremely low maintenance and operating costs.

Curtailing heat problems in industrial plants with the help of evaporative cooling

By Debashish Roy Choudhury AVP, ARCTIC Division, DRI | Added 05 September 2022

Heat is a very common problem in industrial plants. Insufficient cooling intervenes with the day-to-day operations of the plant, which causes the main problem of poor performance of the company. The rising temperature can make the environment within the premises uncomfortable, rendering it unsuitable for working conditions. In case employees are exposed to a prolonged period of excessive heat, it gives way to a phenomenon called heat stress that sharply affects the productivity of the workers. Therefore, achieving optimal industrial ventilation is imperative for industrial plants to ensure the highest performance from the employees.

But considering that industrial spaces are inherently complex structures loaded with heavy machinery, cooling the premises becomes tricky. Additionally, the critical processes being carried out emanate a lot of heat that amplifies the heat issue of the space. This mandates the installation of a highly effective cooling solution to ventilate the industrial plants substantially. Controlling the temperature is essential to retain the integrity and efficiency of the industrial workspace.

Along with the complexity of the place, a lot of energy is wasted in cooling down the extra space. Here, Industrial Evaporative Cooling is the most viable solution suitable for cooling such a large space. It is best suited to provide cooling solutions in the most economical way. It requires minimal capital costs for installations, and the average price for system setup is one-fourth the cost of setting up an air conditioning system.

The mechanisms involved in Industrial Evaporative Cooling make use of natural resources, hence, the entire process is environmental-friendly. It extracts 100 percent natural fresh air from the surroundings to cool down the large industrial space. In the process, it also ensures a continuous supply of fresh oxygen to the room which removes all the fumes, odor, carbon dioxide, and other airborne impurities, and the built-in dust from the enclosed space. This continuous influx and circulation of fresh air reduce the sultriness within the premises. At the same time, it eliminates the stagnant indoor air, which is a major reason for the growth of viruses and bacteria. It is quite evident that evaporative cooling not just cools down the industrial plant, but also plays an imperative role in improving indoor air quality. It majorly contributes to reducing the carbon footprint.

Making use of natural resources, evaporative cooling automatically reduces the temperature by 10 °C to 12°C by simply filtering hot, dry air through the water-saturated cooling pads. Here, water evaporation initiates the formation of cool vapor to achieve the cooling effect. Along with this, the innovative cooling solution is well-equipped with high adsorbent materials responsible for amplifying saturation efficiency. All the factors cumulatively reduce the running cost of the machines by adding to the productivity of the machines. The energy consumption is substantially reduced where it utilizes 80 percent less electricity in comparison to other air conditioning alternatives available in the market. Installing brands like ARCTIC can efficiently help in meeting the air quality requirements, where it is adept at achieving cooling solutions in a comfortable and hassle-free way.

There are instances where the machines are vulnerable to getting damaged due to overheating of parts.

Energy recovery ventilators providing energy-efficient solutions for improving IAQ

By Rahul Aeron AVP, DRI-Desiccant Rotors International | Added 17 August 2022

The rapid rate of urbanization has given rise to the issue of air pollution. Efforts are being made at the global level to tackle the issue wreaking havoc on the environment. Looking at the magnitude of outdoor air pollution people fail to recognize the indoor air pollution existing in their close proximity. But the indoor air pollution is as detrimental as outdoor air pollution and at times can even exceed the degree of damage incurred on the individual as it is unable to find an escape from the enclosed space.

Moreover, the present age building structures with tight designs for restricting filtering of the air inside are further compounding the problem by leaving no space for ventilation. The presence of indoor air pollutants like formaldehyde, asbestos, VOCs dust, pollen, dirt, pet dander, biological growth, and excess humidity within the enclosed space, invariably deteriorates the Indoor Air Quality (IAQ) making it 2-3 times more polluted than the outdoor air. The vulnerability of the occupants increases substantially as poor IAQ leads to serious short-term and long-term health effects that may not show immediate signs but remain present as an underlying ailment in a subtle way. While breathing issues, lethargy, and pain in the eye, are some of the common and direct consequences of poor ventilation, there has been an emergence of a phenomenon called ‘Sick Building Syndrome’ that impacts the overall health and well-being of the person. People with pre-existing allergies and asthma conditions are the worst affected.

The intensity of the problem magnifies in large commercial and industrial spaces which have complex, packed structures leaving no scope for influx or outflux of air and generally are huddled with a large number of people. While the poor IAQ can negatively impact health, in places like offices, schools, and other workplaces, the uncomfortable conditions can immensely meddle with the concentration power of the individual and lead to reduced productivity of the occupants within the building.

The menace of poor IAQ can be curtailed by introducing clean fresh air from outside to the building. Energy Recovery Ventilation (ERV) is the most viable solution for improving the IAQ by ensuring the continuous circulation of cool fresh air. The ERV is balanced mechanical ventilation that preconditions the fresh air coming inside by recovering energy from the outgoing stale air to match the indoor temperature. ERV is highly efficient at getting rid of the stale air inside the building and replacing it with fresh air from outside. It is a versatile technology that is not just limited to the exchange of dry heat but goes a step further and removes the moisture from the space as well. Adding to the list of advantages, it is well adept at minimizing the energy loss where the heat exchangers transfer moisture and heat from outgoing stale / exhaust air to incoming fresh air through out the year.

Therefore, energy recovery ventilation is the way ahead for smart buildings which have value for energy saving. It functions smoothly without interfering with the operating capacity of the HVAC systems but contributes immensely to enhancing its efficiency. This is the most sustainable solution for achieving comfortable conditions within a building in the most environmental-friendly way.

Quality air solution to cool down warehouses is of utmost importance given to the inherently large space it poses. These areas have high ceilings; where all kinds of goods from lightweight cartons to heavy-load goods are stored. It forms an essential part of the logistics where goods are stockpiled to be moved from one place to another.

The warehouses are majorly managed by an on-ground workforce who use a mix of manual as well as heavy-weight machinery for the smooth movement of the goods. Given to the nature of work being carried inside tremendous amount of heat is invariably generated within the vicinity of the warehouse. Unfortunately, this gives rise to high temperatures making the working conditions unsuitable for people within the warehouse. Exposure to excessive heat can lead to a condition of heat stress which can acutely intervene with the working efficiency of the individuals and negatively affect their productivity. Therefore, temperature control is one of the most important and efficient factors required for the maintenance of the warehouse.

Considering the large area, Industrial Evaporative Cooling is the most economical cooling solution for warehouses. Cooling down a large warehouse at times becomes very tricky as going for conventional methods consumes a lot of energy. Compounding the problem, a lot of energy is wasted because of the extra space. In such instances, evaporative colling requires minimal capital cost for installation and the average cost to set up the system is one-fourth as compared to the air conditioning option.

Additionally, it is an energy-efficient mechanism making use of natural resources that further reduces the running costs of the machines. The best part of installing innovative cooling solutions are that it is being backed up with high saturation efficiency and highly adsorbent materials that amplify the efficiency of the system. This results in minimized consumption of energy accounting for 80 percent less electricity usage as compared to other alternatives.

As stated above as evaporative cooling utilizes natural resources it is highly environmentally-friendly in its approach. It works by taking 100 per cent natural fresh air from the surroundings for cooling down the large warehouse and at the same time also ensures that there is a continuous supply of oxygen within the premises. The mechanism is well adept at the influx and circulation of fresh air in the otherwise packed and sultry warehouse. This plays an instrumental role in effectively reducing the temperature by 10° C to 12° C by simply directing hot, dry air through the water-saturated cooling pads for filtration. As a result, the water evaporates which induces the formation of cooling vapor. This in addition to cooling down the warehouse also eliminates the stagnant indoor air which if left unattended can encourage the growth of viruses and bacteria. In the process, it gets rid of the fumes, odor, carbon dioxide & other airborne impurities, and built-in dust from the enclosed air and consequently improves the indoor air quality at the same time. Cumulatively, it is a given that industrial evaporative cooling is helpful in reducing the carbon footprint.

In addition to the above-stated benefits, the cooling solution is vital to ensure the smooth functioning of the machines which could potentially be damaged due to the overheating of the parts. On the other hand, maintaining a cool temperature helps the employees to deliver error-free work that boosts their morale and productivity, which adds to the profitability of the company.

The advantage of working with an established brand like ARCTIC is the deep understanding and expertise in duct designing, specially designed cooling pads, exhaust design systems for stale hot air displacement and allowing cool fresh air to be introduced effectively & economically; all coming from decades of knowledge. This in turn leads to repeat business orders and long-term relationships for the ARCTIC brand.
