How Does a Split Unit Heat Pump Provide Heating?

A split unit heat pump provides heating through a process called the refrigeration cycle. This cycle involves four main components: the indoor unit, the outdoor unit, the refrigerant, and the compressor.

First, the outdoor unit absorbs heat from the outside air, even in cold temperatures. The refrigerant, a fluid that easily changes between gas and liquid, flows to the outdoor coil.

Next, the absorbed heat warms the refrigerant, causing it to evaporate and turn into a gas. Then, the compressor, located in the outdoor unit, compresses the gas. This compression increases the refrigerant’s temperature and pressure.

Afterward, the hot gas travels to the indoor unit through insulated pipes. In the indoor unit, the refrigerant releases its heat into the indoor air as it passes through the indoor coil. This process heats the air, which is then circulated throughout the living space.

Finally, the refrigerant, now cooled and back in liquid form, returns to the outdoor unit. The system continuously repeats this cycle, providing consistent heating.

How Does a Split Unit Heat Pump Provide Cooling?

A split unit heat pump provides cooling through a series of specific steps. First, it has two main components: an indoor unit and an outdoor unit. The indoor unit contains an evaporator coil, while the outdoor unit houses a compressor and a condenser coil.

When cooling is needed, the heat pump absorbs heat from the indoor air. The indoor unit’s evaporator coil cools down the air by using a refrigerant that evaporates within the coil. This process removes heat from the air, making the indoor space cooler.

Next, the compressor in the outdoor unit compresses the refrigerant gas, increasing its temperature and pressure. This heated gas then flows to the condenser coil, where it releases the absorbed heat into the outside air. The refrigerant then cools down and condenses back into a liquid form.

The cycle repeats as the cooled refrigerant returns to the indoor unit. The fan in the indoor unit blows the cool air back into the living space. This continuous process of absorbing, compressing, and releasing heat keeps the indoor environment comfortable and cool.

Overall, the split unit heat pump efficiently cools a space by transferring heat from indoors to outdoors.
