HVAC units regulate temperature of room. In winters, it transforms cool air into temperate and does the vice versa in summers. In summer season it makes warm air cool and quite pleasant. In addition to this regulation, it also flushes out allergens and dust particles refreshing the air and enhancing ventilation of the room. Knowing about the basics of HVAC is imperative because it will help you know about the system of AC, its parts and their functioning. This knowledge will again help you out in proper maintenance of AC and prolonging the lifespan. Also, you can make the most use of it. Here are mentioned some of the parts and their purpose: Refrigerant Refrigerant mixes gas and liquid that passes through the lines of AC in HVAC package. On using low temperature refrigerants are present in liquid form but slowly take up the gaseous form on being heated. This process makes a crucial and important stage of cooling system. Compressor Compressor uses copper tubes which are helpful in making HVAC system flow throughout. It is a very important part of HVAC. In its simplest state, compressor pushes refrigerant in a coil. After that, it throws out the gas in condenser. This part controls the cooling capacity of AC. Condenser coil Condenser coil works in a similar fashion as radiator of car. It contains aluminium fins. It also has a copper tube which keeps running in a specific (back and forth) position. Hot air is produced from the condenser. From here, it reaches the expansion valve. Actuator valves Actuator valve is the device that joins HVAC system with valves. It compresses the air. There are many types of actuator valves available in market these days. V series by Barber Colman is known for their reliability and efficiency. Functions of HVAC System Usually HVAC has three basic functions: cooling, heating and ventilating. Heat in this system is generated by oil, gas or electricity. Heat is generated and forces a fan, gets free in a duct system. When the temperature of room gets to the set one, burner gets stop automatically. If the inner temperature plummets down, heater will get switched on to produce more heat. On the other hand, compressor powers cooling system. It flushes out the heat from the room and drags the cool air inside. Ventilation is designed to pass the air to the interior. So, this working of HVAC system makes it a complete package for rooms. Ventilation is very necessary for refreshes and relaxed experience.
