How a Heat Pump Cools Your Residence

In Edmonton, heat pumps can be a popular choice to heat and cool your house.

They seem almost like an air conditioner. In fact, they work in a similar fashion during warm weather. Since they have a reversing valve, they can shift humidity in the opposite direction as well as add comfort to your house when temperatures drop.

Not sure if you use a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and run it online. If you find you own a heat pump, or you’re thinking over purchasing one, learn more about how this HVAC equipment keeps homes comfy.

How Heat Pumps Operate

Heat pumps rely on a refrigeration system much like an air conditioner. Most can work akin to a ductless mini-split, since they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to move humidity. The outdoor unit also contains a compressor and is enclosed by metal fins that function as a heat sink to help transfer heat efficiently.

Summertime Cooling

In cooling mode, the refrigerant is in the evaporator coil. Air from indoors moves over the coil, and the refrigerant extracts humidity. Wetness in the air also condenses on the coil, falling into the condensate pan below and flows away. The following cool air circulates through the ductwork and back into your residence.

Meanwhile, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, leading it to heat up even more. As it moves through the condensing coil, the outdoor fan and metal fins help to emit heat to the outside. The refrigerant heads back into your house, traveling through an expansion valve that chills it considerably, readying it to go through the process from the start.

When your heat pump is installed and maintained properly, you’ll get efficient cooling comparable to an energy-efficient air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange process occurs the other way around. By flowing in the opposing direction, refrigerant pulls heat from the outdoor air and adds it into your home to warm the inside.

Heat pumps working in heating mode are most efficient when the temperature is above freezing outside. If it becomes too cold, a backup electric resistance heater kicks on to keep your house comfy, but your heating bills rise as a result.

Heat pumps operate longer than furnaces because the air doesn’t turn as hot. This helps maintain a more stable indoor temperature. Also, because heat pumps move hot air rather than making it from a fuel source, they can operate well above 100% efficiency. You should receive 30–40% savings on your heating expenses by getting a heat pump.
