Heating, Ventilating and air-conditioning is known as HVAC. HVAC systems are used to provide ventilation and reduce air infiltration and maintain the pressure relationships between spaces. HVAC systems are vitally important for the preservation of historic artifacts. The main purpose of HVAC is to maintain good quality of air through ventilation with filtration and provide comfortable air. It is Easier to maintain due to reduced number of components and few units to access.HVAC chillers vary in terms of condenser cooling method, cooling specifications and process pump specifications.
There are several condenser cooling methods. HVAC chillers include a compressor, condenser, thermal expansion valve, evaporator, reservoir, and stabilization assembly. The components used in HVAC systems were hand held with industrial revolution. HVAC systems are playing a main role of maintaining proper air flow. It needs a proper amount of designed air flow through out the HVAC system. To maintain the proper air flow HVAC air filters are needed, there are three different types of air filters are used to maintain the proper air.
