How To Select A DC Inverter Swimming Pool Heat Pump

At present, the swimming pool and SPA industry is booming day by day, and the requirements for supporting equipment and products are also getting higher and higher. However, many people still don't know how to choose the basic product of DC inverter swimming pool heat pump due to limitations of professional knowledge. We'll cover this in more detail below.

Here is the content list:

• Flow rate

• Head and shaft power

• Efficiency

Flow rate

DC inverter swimming pool heat pump flow refers to the heat output through the pump port in a unit of time. Of course, it is a measure of the pressure, potential energy, and kinetic energy obtained by the whole system circulation filtration in the pump resistance, so the flow rate is the flow under a certain head.

Head and shaft power

The head, also known as the DC inverter swimming pool heat pump head, unit weight of liquid through the pump to obtain energy. The system head of a particular swimming pool circulation filtration system has a certain range of changes, the initial filtration, the system head is small, and at this time the flow is large. After running for a period of time, the filter interceptor gradually blocks the water channel, the pressure head becomes larger, and the flow rate correspondingly becomes smaller. For pumps with the same inlet and outlet diameters, when the vacuum gauge on the suction tube and the pressure gauge on the outlet tube are installed at the same level, the pump head is the sum of the suction and pressure ranges. Factors affecting the size of the pump head are the structure of the pump (impeller size, bending degree), speed, and flow. Shaft power refers to the power transferred to the pump shaft by the motor, that is, the power consumed by the pump shaft. These two factors can be used as a reference for purchasing a DC inverter pool heat pump.

Efficiency

The ratio of effective power Ne(refers to the mechanical energy obtained by fluid power) and shaft power of the DC inverter swimming pool heat pump is called efficiency, n = Ne/No. Because the heat pump can not put the motor input power to the pool completely without waste, so there must be energy loss in the heat pump, so the use efficiency to measure the size of the energy loss and the effective use of energy. The causes of energy loss include volume loss, hydraulic loss, mechanical loss, etc.

Through the description of the above parameters, we know that the most important thing for the selection of a circulating heat pump swimming pool /SPA pool is that the flow and head should meet the design requirements of the water body, and then consider the requirements of energy consumption from the two parameters of shaft power and efficiency. The basic requirements of the pump should start from the main performance parameters of the circulating pump. Therefore, the choice of DC inverter swimming pool heat pump can be considered from the flow, head, shaft power, and efficiency.
