The hotel uses air energy plus water tank to provide central heating water, but the room hot water temperature is always unstable?

I can tell you clearly that the problem of high and low water pressure during bathing is caused by the use of booster pump in your water supply system. When using water for bathing, the pressure of cold and hot water is released, and the head, pressure and water consumption of cold and hot water pumps are different, resulting in pressure loss and alternating pressurization of cold and hot water pumps.

Solution 1: Look at the floor height. If the floor is not high, the cold water will be supplied by the city network and the hot water booster pump will be used separately without affecting the tap water supply. The transformation is quiet, but the conditions are limited.

Solution 2: Change the water supply mode. The highest water supply point is more than 7 meters, and cold and hot water storage tanks are set up respectively to supply water by natural pressure. But pay attention to the height of the water tank, the lowest pressure area and the highest pressure load to avoid insufficient pressure or excessive pressure. The transformation action is the biggest and the cost is high, but it can save the electricity fee of the booster pump, and the energy saving effect is good.

Solution 3: Provide small household pressurized water pumps for the hot and cold water pipes in each room to stabilize the pressure. The transformation power is the smallest, but the cost is the highest and the maintenance rate is the highest. Not recommended.
