In every kind of climate, a heat pump (varmepumpe) is there to give heat or coolness. It plays a vital role in one residential space. With the function it provides, it gives comfort to each and every one. But heat pump is not just a simple thing that operates to its purpose. So, let’s get to know its basics.
Basically, a heat pump is an air conditioning device that moves heat energy from one place to another. It works like absorbing or extracting heat on the inside and pumping it outside. So how does it work? The example of this heat pump concept is an air conditioner. When the air conditioner is working, it gives cool temperatures inside the house, but if you go outside, at the back of the unit, it exhausts warm air. That is for the reason that air conditioner pumping out the heat inside the room. Heat pumps work the same but it is fully reversible through its mechanism so no need for a manual rotating of the unit in order to do both functions. It could supply cooling and heating depends on the needed temperature in the house all year round.
The heat pump system works with the help of two heat surfaces. One heat transfer surface is located outside the structure and the other is located inside the structure. These are called the evaporator, the one who absorbs the heat and the condenser which is responsible for rejecting it. On heat pumps, both of the surfaces function as either condenser or the evaporator. The heat transfer is possible through refrigerant, it is a chemical substance that absorbs and rejects heat energy quickly, therefore, it facilitates the desired heat transfer. There is two basic types of heat pump, the air source which absorbs heat from the outdoor air in winter and rejects heat into the outdoor in air summer. And the ground-source heat pumps or called earth-energy which draw heat from the ground.
