PTAC means Packaged Terminal Air Conditioner. PTAC is usually a compact style of air conditioners that mixes the compressor, condenser, evaporator and expansion valve in one one unit.

Air Conditioner – Linked to the inside cooling coil, the compressor pumps refrigerant back and forth, extracting heat and humidity through the indoors.

Heating: The HVAC system may perhaps contain a furnace, boiler, warmth pump, or electric powered heaters to provide heating. Heat is produced because of the heating supply and then dispersed within the home with the air-managing tools.

COP means Coefficient of Performance. COP would be the universal measurement unit to the Electricity performance of air conditioners. COP is calculated by dividing the cooling output in kW by the ability input in kW. By way of example, an air conditioner incorporates a cooling capability of two.

IFR stands for Indoor Enthusiast Relay. IFR is utilized to manage the operation on the indoor supporter motor. Upon energized, it'll bodily lid and shut the circuit therefore letting electricity to pass through and start the indoor enthusiast motor.
