Abstract: The present disclosure discloses an integrated regulation and control device and method for light, heat and water in a greenhouse, and a greenhouse. The regulation and control device includes a shading and condensing plate arranged at a top of a chamber of a greenhouse; a cavity is formed in the shading and condensing plate; the shading and condensing plate is further provided with a water inlet and a water outlet which are communicated to the cavity; the regulation and control device further includes an energy supply system and a heat dissipation device; the energy supply system can inject a cold source into the cavity through the water inlet; the energy supply system can also transport a heat source to the heat dissipation device; the heat dissipation device can dissipate heat of the heat source into the greenhouse.

Abstract: The present disclosure discloses a water recycling type greenhouse, including a greenhouse body; a water collection device is arranged in the greenhouse body; the water collection device is provided with an air inlet and an air outlet; a condensation portion and a reheating portion are arranged in the water collection device; and the water recycling type greenhouse further includes an energy supply system. Air in the greenhouse body can be poured into the water collection device from the air inlet, flow through the condensation portion and the reheating portion in sequence, and finally be discharged into the greenhouse body again from the air outlet. When the heated air is discharged into the greenhouse body again, a decrease of the temperature of the greenhouse is not likely to occur, and normal growth of plants is not easily affected.
