We literally compare the heat pump to a refrigerator. When we think of a heat pump we can think of a system that has a cold side and a warm part just like a refrigerator.
As a refrigerator extracts the heat inside it and releases it backwards (the black coil called the condenser), the heat pumps extract the heat from the water, soil or air and place it in the house.
The heat pump’s magic to transfer heat from one side to another is based on the special properties of the refrigerants present in the system. These refrigerants take heat by evaporation and give it through condensation at low or ambient temperatures.
The refrigeration cycle is very simple to explain. It is in a refrigeration cycle that part of the refill is in the liquid state and the part is in the gaseous state as we see in a gas lighter.
The process begins when the compressor begins to compress the gaseous refrigerant into a heat exchanger with air or water. This switch can simply be a pipe like the refrigerator.
Compressed refrigerators increase their temperature if the refrigerant can yield heat to the outside when it condenses on the wall of the heat exchanger and goes into the liquid phase.
This liquid is pushed by the gas coming out of the compressor to a very small hole through which it passes in the liquid form, here is the most interesting phenomenon. pompa de caldura
After the liquid passes through the orifice, the downstream pressure of the liquid is very low compared to the one before, and the refrigerant begins to vaporize with ambient heat absorption until it becomes gas and enters the compressor.
The refrigeration cycle was resurfacing.
Today the heat pump is one of the most advanced and environmentally friendly heating systems on the market.
