What is HVAC unit?
The HVAC unit is a term used for the centralized heating, ventilation and air conditioning system. The HVAC unit allows comfortable control of the internal temperature and climate of the building. Before the advent of the modern HVAC system, effective cooling and heating of the interior was often limited to a specific room or part of a building with localized heating or cooling.
The HVAC unit provides interior cooling by drawing warm inner air into the system through a series of air racing channels. The air then moves through a series of chilled coils. When the air moves through the coils, the heat in the air is transmitted to the coolant in the coils. The fan or blower sends the chilled air back to the inside of the building via the pipeline.
When cold air is directed to the building, the heated refrigerant is directed to the unit outside the building. Here the coolant heated flows through a series of coils through a cooling fan. The cooling fan helps to dispel heat from the refrigerant, which is then directedItem to the interior of the HVAC unit to re -start the cooling process.
The heating function in the HVAC unit operates in almost the same way as the cooling function. The air is drawn into the system through a line of pipes. As the air flows through the system, the furnace is heated through heat exchangers. The fan or blower sends heated air back to the interior of the building via a line of pipes.
In addition to heating and cooling the interior of the building, the HVAC unit can actually improve the quality of the inner air by ventilation and filtration. As mentioned earlier, HVAC systems attract internal air through a line of pipes. The air movement prevents stagnation and circulates the inner air and removes odors and excessive humidity. As the air move, some of the existing inner air, can also be replaced from the air taken from the outside of the building itself. Constant introduction of fresh airHU also helps maintain air quality in the building.
When the air is drawn into the HVAC unit, it is also focused through a series of filters. The inner air of the building is a mixture of various things such as particles of human skin, insects, insects, pets and pollen. The filter system protects the unit from these and other air pollutants that could cause damage if it could be entered into the internal functioning of the unit.
The filters not only protect the HVAC system, but some types of filters are designed to improve the quality of the building. The HEPA filter (highly effective particle fever) captures at least 99.7% of all airy particles and removes almost all allergens from the air. Because pollutants are trapped in the filter, they are prevented from re -entering the building when the air -mounting them back into it.
