GREENHOUSE WITH WATER RECIRCULATION SYSTEM

Disclosed in the present invention is a greenhouse with water recirculation system. The greenhouse includes a greenhouse body, where a water collecting device is arranged in the greenhouse body, the water collecting device is provided with an air inlet and an air outlet, and a condensing portion and a reheating portion are arranged in the water collecting device. An energy supply system is further included. Air in the greenhouse body can be injected into the water collecting device from the air inlet, flows through the condensing portion and the reheating portion in sequence, and is finally discharged into the greenhouse body again from the air outlet. In such a process, the condensing portion has a low temperature under cold supply of the energy supply system, and when the air with higher humidity flows through the condensing portion, moisture is condensed on a surface of the condensing portion, such that the water collecting device has the function of taking water from the greenhouse air. When the dehumidified air with a lower temperature flows through the reheating portion, since the reheating portion has a high temperature under heat supply of the energy supply system, the reheating portion can heat the air flowing therethrough. A temperature of the greenhouse is less likely to be reduced when the heated air is discharged into the greenhouse body again, and normal growth of plants is less likely to be affected.
