What is the principle of water air conditioning?

The so-called water air conditioner should be a groundwater circulation system. We know that the normal temperature about 15 meters underground is 18 degrees. In the summer, a water pump is used to pump the water up and pass it through the indoor fan coil to achieve cooling purposes. The return water is The pipes flow back into the ground. Winter cycles like this too. Currently, the state does not advocate the use of groundwater as water for air conditioning.

The other type is the lithium bromide refrigerator, which uses salt water to heat to form high-pressure steam to absorb and release heat to achieve the refrigeration effect. As it ages, the refrigeration capacity will decrease.
