Heat Pumps For Cold Climates

Are you looking for a cold climate heat pump for hot water at home? If yes, you should look no further than the Arctic Cold Climate Heat Pump. This heat pump is specifically designed to operate in below-freezing temperatures, i.e., -25 C or – 15F. However, the air below the freezing contains the same amount of relative energy like the same it does above freezing temperature. You should understand the concept that air has energy, and in space, the temperature is absolute zero, i.e., 273 C, where the air doesn’t contain any energy. It is the concept behind the working of the Arctic Heat Pump.

The following principle a heat pump uses is the warm air always moves to the cold air. Generally, warm air contains more energy and more molecules colliding than cold air. So naturally, warm hair migrates to the cold air to establish an equilibrium condition. The Arctic series heat pump uses Freon, which does not freeze until – 50 C. This heat pump can cause the warmer – 25 C air  for transferring energy to the heat pump containing colder Freon.

Another principle a heat pump considers is that the pressure determines the boiling point. Different substances have different boiling points. The boiling point can change with changing pressure. Water boils at 100 C at 14.69 Psi sea level. With less pressure, the water will boil faster than usual. On Mount Everest, the pressure remains at only 4.89 psi, making the water boil around 71 C. because of the less pressure.

A heat pump for hot water works on the refrigeration cycle which uses Freon. The cycle involves transitioning the state from liquid to gaseous  at a much colder temperature than water. By adjusting the Freon pressure, the heat pump unit can manipulate the occurrence of phase change. In addition, the heat pump uses a refrigerant known as R410a, which is perfect for storing energy in cold climate conditions.

You can set the refrigerant temperature to boil as cold as – 50 C by minimizing pressure inside the heat pump. The cold – 50 C Freon passes through the heat exchanger, and the warmer energy of the surrounding air – 25 C, moves to the colder Freon naturally across the heat exchanger. This process causes the Freon to absorb more energy.

When the heat pump starts heating up, the Freon gas evaporates and converts to gas. After that, the Freon gas goes to the compressor, which causes a significant increase in temperature as the volume reduces. Then, the hot gas gets transferred over the heat exchanger, and on the other side is the colder water or glycol. The energy goes from the hot air to cold air and starts heating the water or glycol loop in the home. The refrigerant begins losing its heat energy which causes it to cool back to the liquid to start the refrigeration cycle again.

All of them are the basic principles behind the refrigeration cycle. If you understand these principles, you can know how a heat pump works even at – 25 C or – 15 F. simply, a heat pump is a way of transferring energy from one source to another. A geothermal heating system uses the same principle, which pulls out the warmer energy from the ground and provides it to the house by doing a series of heat exchange processes.
