Mitsubishi Air Conditioning Prices. Performance.
The amount of heat that can be pumped up to the temperature difference between the hot and cold spots. The greater this difference, the lower the throughput of the machine.
Heat pumps have a performance, called COP (coefficient of performance), greater than unity. Although this may seem impossible, is because you are actually using moving heat energy instead of producing heat as in the case of the electric heaters.
Mitsubishi Mini Split Air Conditioning. Compressor.
A very important part of this heat is taken from the enthalpy of atmospheric air. In all heat pump verifies that the heat transferred to the hot reservoir is the sum of the heat extracted from the cold over the power consumed by the compressor, which is transmitted to the fluid.
Ductless Air Conditioning Cost. The Effectiveness of a Heat Pump.
Since the effectiveness of a heat pump depends on its use, there are two different expressions of the COP. If the machine is being used to cool an environment, the practical effect is the heat extracted from the cold:
If the heat pump is being used to heat a zone, the useful effect is heat introduced: A typical heat pump has a COP of between two and six, depending on the difference between the temperatures of the two foci.
