Question

An air-to-air heat pump has many of the same components as an air conditioning system. The major difference is that a heat pump also has a (an)________.

Answer 1

The major difference between an air-to-air heat pump and an air conditioning system is the presence of an evaporator in the heat pump.

Step-by-step explanation:

Air-to-air heat pumps are similar to air conditioning systems but have an additional component known as an evaporator. The basic components of a heat pump include a condenser, an expansion valve, an evaporator, and a compressor. In the heating mode, heat transfer occurs in the evaporator from the colder outdoor air, turning it into a gas. The compressor then increases the temperature and pressure of the gas and forces it into the condenser coils inside the heated space. Heat is transferred from the gas to the room as the gas condenses into a liquid.
