How does a heat pump's coil function?

A coil is a crucial part of a heat pump, which moves heat from one location to another. The coil, which is commonly formed of copper tubing, is intended to make it easier for heat to be transferred from the refrigerant to the heated or cooled water or air.

The coil is utilized in both the indoor and exterior units of a heat pump. The coil serves as the evaporator coil in the outside unit, transferring heat from the ambient air or water to the refrigerant in the coil. The heat is subsequently transferred into the indoor unit by the refrigerant.

The coil in the indoor unit serves as the condenser coil, dissipating the heat from the outdoor unit into the space's air or water. After cooling, the refrigerant goes back to the external unit to continue absorbing heat.

The indoor and outdoor coils, a compressor, and a reversing valve make up a closed loop system that the coil in a heat pump uses to circulate refrigerant. The reversing valve enables the refrigerant flow to be switched around, allowing the heat pump to perform both cooling and heating duties.

The coil is a crucial part of a heat pump because it makes it easier for heat to move from one area to another, which enables the system to deliver effective heating and cooling.

A heat pump moves heat energy from one place to another using refrigerant. When in heating mode, the heat pump transports heat from the water or air outside to warm the interior space. The heat pump releases heat to the outside air or water while it is in cooling mode, which cools the interior space.

The heat transfer process happens in the coil. The refrigerant is at a low pressure and temperature in the outdoor unit's evaporator coil. The coil absorbs heat from the environment when warm outdoor air or water flows over it, which causes the refrigerant to evaporate and change into a gas.

The gaseous refrigerant is then compressed and has its temperature and pressure raised as it passes through the compressor. The refrigerant then passes through the indoor unit's condenser coil while being hot and under high pressure.

The hot refrigerant releases its heat energy into the indoor air or water in the condenser coil, which then heats or cools the surrounding area. The cycle then starts over when the refrigerant condenses back into a liquid.

Overall, the coil is essential for moving heat energy from one place to another, enabling the heat pump to properly perform heating and cooling duties. The coil used in a heat pump can be of several types, but the three most typical forms are air-source, water-source, and ground-source coils.

What do the coils used in heat pump systems go by?

Evaporator coils and condenser coils are the two types of coils used by heat pumps. The heat pump's condenser coil is found in the indoor unit, while the evaporator coil is found in the outdoor unit.

While the condenser coil is sometimes referred to as the outside coil or the heating coil, the evaporator coil is also occasionally referred to as the indoor coil or the cooling coil.

The heat from the water or outdoor air is absorbed by the evaporator coil and transferred to the refrigerant. The heat energy is subsequently transferred by the refrigerant to the indoor unit, where it is released by the condenser coil into the indoor air or water.

Typically, copper tubing with aluminum fins connected makes up the evaporator and condenser coils. The coils' surface area is increased by the fins, resulting in more effective heat transfer between the refrigerant and the air or water around it.

Some heat pumps may additionally feature auxiliary or supplemental heating coils in addition to these two primary coils. In extremely cold climates or when the heat pump is unable to supply enough heat to meet the requirements for indoor heating, these coils are often employed as a backup heat source.
