Know How Heat Pump Provides Both Heating & Cooling!

When heating and air conditioning professionals talk about a heat pump, you might assume they are referring to a heating system only. But, this is just half of the truth. A heat pump is designed with all of the same components as a standard central AC, but with a little bit extra added in. That enables it to both heat and cool your home with a single system.

Heat pump units need professional installation, maintenance, and repair services in order to function properly when you need them most. That is why you should leave your Heat Pump Service in Christchurch to the professionals.

Heat Transfer Mechanism

A heat pump can heat homes with mind-blowing efficiency because it doesn’t need to generate new heat. Rather, the heat pump makes use of heat that is already present in the air outside. Now, this doesn’t mean that you should open your windows during the winter months in hopes that warm air will flow in. How then does this method of heat transfer work?

Refrigerant Cycle

To know how a heat pump heats, you first need to learn how a central air conditioner cools because they do it the same way!

A central air conditioning doesn’t generate new “cooling effect.” When you use an air conditioner to cool the air in your home, that cooling effect that you feel is actually the absence of heat. The central air conditioner removes heat from the air in your home by evaporating refrigerant in the indoor evaporator coil. At that point, the heated refrigerant heads out to the condenser coil in the outdoor unit. There, it is condensed and its heat is released.

Reverse Process

The heat pump cools a home in much the same way as the central air conditioner. Using a component called a reversing valve, the system reverses its function by reversing the flow of its refrigerant and the function of its coils.

That means that in its heating mode the heat pump evaporates refrigerant in the outdoor coil. That enables it to expel heat from the air outside. That refrigerant is then compressed, which further improves its thermal energy. At that point, the refrigerant heads to the indoor coil, where it is condensed in order to release its heat. That enables you to warm your home without generating new heat!
