It's very hot, but many people still go to the heated swimming pool. What is the principle of constant temperature in swimming pool? Such a large pool of water consumes a lot of energy.

The difference between constant temperature swimming and ordinary indoor swimming pool lies in the addition of a constant temperature device. The principle is similar to our water heater. When the water in the swimming pool is pumped away by the pump, the sand tank will flow into the heat pump for heating and then flow back to the swimming pool. Therefore, the bigger the swimming pool, the higher the heat pump power is needed, and of course, the more fuel or electricity is needed. At present, most of the products used in our country are coal-fired, gas-fired heat pumps are the main ones, and the new ones are air heat pumps, with lower cost and energy consumption than before.
