Air energy heat pump: absorbs heat from the air through the evaporator, the compressor consumes electric energy and does work to compress low-temperature and low-pressure gas into high temperature and high pressure gas, high temperature and high pressure gas releases heat in the condenser to heat the pool water, and then the expansion valve throttling and reducing pressure, the liquid refrigerant enters the evaporator again to absorb heat, and the cycle is reciprocating to realize the pool water heating.
Water source heat pump: extract heat from groundwater, surface water and other water sources to heat the pool water, the principle is also based on the reverse Carnot cycle, but the heat source is the water source.
Three integrated heat pumps: pool water heating, dehumidification and air conditioning in one. First, the indoor hot and humid air is heat exchanged with the outdoor fresh air, and then the warm and humid air flows through the evaporator to dehumidify and release latent heat and sensible heat, which is absorbed by the refrigerant. The refrigerant then heats the pool water and air through the heat exchanger to achieve the air conditioning dehumidification function, and at the same time, the fresh air is added to ensure the indoor air quality.
Equipment selection:
It should be considered according to the size of the swimming pool, water temperature requirements, local climate conditions and other factors. In general, the larger the pool area, the higher the water temperature requirements, and the colder the climate, the greater the required heat pump power.
Also consider the energy efficiency ratio of the equipment, the corrosion resistance of the material, the ease of operation and the maintenance cost. For example, air energy heat pump has the advantages of high efficiency, energy saving, environmental protection and safety, and is not subject to regional restrictions, and is one of the common options for swimming pool heating equipment.
Installation points:
Avoid installation in places that contain lubricants such as mineral oil, have large power supply variations, have strong electromagnetic fields, have corrosive gases, are closed without air recirculation, are permeable to oil, and have flammable gases or materials.
It is best to build the support surface above the ground to ensure that the weight of the equipment can be supported without noise due to vibration, while allowing condensate and rainwater to drain smoothly.
The drain pipe should be kept open, and the pressure regulator should be switched on and off periodically to eliminate lime deposits; In a non-icing environment, connect the drain pipe and pressure reducing valve vertically downwards.
