Heated swimming pool, also called indoor heated swimming pool; That is, the water temperature of the swimming pool is kept at 26-28 degrees, which is suitable for the human body. At the time of design, the water in indoor swimming pools is generally heated in various ways to maintain a constant temperature.

Constant temperature system

In winter, heat pump takes refrigerant as heat medium, absorbs heat energy in air (indirect heat exchange in evaporator), upgrades low-temperature heat energy to high-temperature heat energy through compressor, and circulates water in heating system (indirect heat exchange in condenser).

In summer, heat pumps use refrigerants as refrigerants to absorb cold energy in the air (indirect heat exchange in the condenser), reduce high-temperature heat energy to low-temperature cold energy through the compressor, and circulate water in the refrigeration system (indirect heat exchange in the evaporator), so that the heat energy (cold energy) that cannot be directly utilized can be regenerated into heat energy (cold energy) that can be directly utilized, and only a small amount of electric energy is consumed, thus obtaining energy-saving returns of 2-6 times the input power.
