The majority of cooling and heating systems are made up of two pieces of equipment: an interior air handler and an outside unit. These systems have a refrigeration cycle in both the outdoor and indoor units. The cycle collects and releases heat from and to the interior unit. Unlike an air conditioner, a heat pump may reverse the refrigeration cycle and deliver heat instead of cooling. A reversing valve connects an indoor and outdoor unit, letting warm airflow into your house or company. The device is also forced back into “cooling” mode during defrosting to prevent it from freezing over in colder temperatures. However, due to a few crucial internal characteristics, it is conceivable for a heat pump to alter the direction of heat exchange. Three significant differences between heat pumps and air conditioners are listed below.
