Pool heat pump heat exchanger

The external piping may flow the pool water to be heated, while the internal piping will flow the refrigerant heated by the compressor. During operation, the refrigerant evaporates from liquid state to gaseous state in the internal pipe to absorb the heat of external water flow, so as to achieve the purpose of heating water. High heat exchange efficiency due to close proximity of two fluid flow regions, but may be limited by cleaning maintenance and pressure loss.

In the application scenario of pool heat pump, whether coaxial heat exchanger or shell-and-tube heat exchanger, the core purpose is to circulate and absorb the low-grade heat energy (such as heat energy in air) in the environment through the compressor in the heat pump system, and then transfer the heat energy to the pool water through the heat exchanger to heat the pool water. This process follows the principle of reverse Carnot cycle, realizes large heat transfer with small electric energy input, and has the characteristics of energy saving and high efficiency
