Shanghai World Expo Park adopts river water source air conditioning, and uses water instead of electricity to adjust the temperature.

1, using the characteristics of river water that it is warm in winter and cool in summer, this is relative. In winter, the temperature of river water is higher than that of air, and it is easy to bring heat. In summer, the temperature of river water is lower than that of air, which is easy to take away cold energy.

2. It doesn't mean that the river water source air conditioner can be warm in winter and cool in summer, but the river water is relatively warm in winter and cool in summer, so it is easier to replace the outdoor part of the air conditioner with the required cold and heat, at least much easier than exchanging cold and heat in the air.

I wonder if you can understand this explanation. This energy collection system is called surface water heat pump system. Rivers, lakes and seas can be used, and so can sewage.
