An air handler is essential in heating, ventilation, and cooling systems. As the name specifies, the unit is responsible for managing conditioned air. From air conditioners to furnaces, the role of air handlers is to move air throughout the building.
An air handling unit is a vital element connected to the HVAC system, but several functionalities differ from one AHU to another. The performance of these units may be affected by the climatic conditions in the region where they are used.
Some units are exclusively utilised for air circulation, while many offer air circulation, air conditioning, and heating. The units are usually customised to meet the needs of customers.
Air handlers – Working
There are various air handlers, but most have standard components such as an evaporator coil, motorised blower, mesh air filter, and more. If cooled or warmed air had to be distributed across the area, the air handling could transfer air to respective components.
Most of the time, the AHU is confused with the evaporator coil as the coil situated outside transfers thermal energy. When AC systems are used, the evaporator coil will eradicate heat and humidity from the office space.
Heat is added to the rooms when you use the heater in HVAC systems. The Air handler also consists of a motorised blower to blow cool or warm air through the building’s ductwork.
Consider the essential factors.
Initially, evaluate the desired airflow that the air handler should manage. If you are aware of this, it will help you choose the right size and capacity for the unit. Ensure you consider the thermal load of the space which needs to be conditioned. Several calculations are involved when evaluating the desired airflow; you need to use L/s (litres per second) as the measurement unit.
Buyers who desire to purchase air handlers should evaluate the size, and your building capacity is the crucial factor to be considered. A small office requires a compact air handling unit, whereas huge buildings require larger handling units.
You need to check the place for installing the air handler. At times, people use the rooftop, which will help them save space. However, the mechanical room is a good choice which many individuals prefer.
Every AHU is different as they serve other purposes. Consider the weather conditions in your locality throughout the year, and it is essential to select the air handlers accordingly. Many people invest in a heating air handler which is not useful in the winter season and vice versa. Top stores offer a wide assortment of air handlers, so purchase the best.
Other factors to consider
Though the factors mentioned above are important, it is essential to consider various other attributes such as the air handler, casing type, filter types, and more. There are two different types, including direct and indirect gas-fired air handlers. You can go for the most common AHU used in the regional market.
Advantages of air handlers
Air handlers can be easily installed outside the building. Though air conditioning outdoor units are installed on the roofs, the indoor units need a separate space inside the building.
Moreover, maintenance on every indoor unit necessitates splurging money. On the other hand, air handlers are easily grouped and installed outside, and maintenance service can be finished in that location.
Find the best air handlers as per the requirements. Many online stores are offering high-end units at cost-effective rates. Check them out to make an informed buying decision.
