How many degrees can the spray in the tin house drop?

Every gram of water drops by 2 degrees. According to the technical effect of spray cooling on the roof of iron house, each gram of water can cool the air per cubic meter by about 2 degrees, and the efficiency of spray cooling is very high for outdoor air. Spray cooling on the roof of iron house means that when the ambient temperature drops below the domestication temperature point (or set point), the shape temperature memory alloy will deform and return to its original normal memory state, and the magnetic coupling system will be driven by the transmission mechanism to close the valve.
