Through the warmer months, air-supply heat pumps operate equally to central air conditioners by making use of a refrigerant to extract warmth from indoors and expelling it outside with the compressor. Whilst running in the course of the chilly-climate months, heat pumps benefit from a reversing valve to switch from cooling to heating modes to work in reverse.
Heat pumps use refrigerant to extract heat from outside to heat dwelling places. In case you are looking at purchasing a heat pump, Look at with your neighborhood HVAC seller about accessible HVAC Electricity tax credits.
TC stands for Thermocouple. TC is usually a form of temperature sensor consisting of two wires of different metals joined at Each individual end. It truly is normally used in gas furnaces and hot h2o tanks for valve and operation controls.
ACU stands for Air-con Unit. ACU is usually a generic expression used to indicate an air-con device, regardless of the sort. The air con device is often AHU, FCU or some other form of air conditioners that gives airflow and air conditioning to a space.
Air Return: Air return refers back to the Portion of the system that marks the beginning in the ventilation cycle. Air return sucks in air, draws it from the filter, and after that passes with the primary system.
