Once the temperature in the greenhouse 1 is too low, the temperature sensor 11 will transmit the low temperature signal to the control panel, and the control panel will open the suction fan 3, the electric heating wire 23, and the electromagnetic valve connected to the shunt pipe 5 and the heating pipe 22. First, the air in the greenhouse 1 will be sucked in by the suction fan 3, and enter the heating pipe 22 through the opening of the electromagnetic valve. After the air is heated by the electric heating wire 23, the air forms a heat flow and is then discharged through the hot air outlet hood 24; when the temperature in the greenhouse 1 is too high, the temperature sensor 11 will transmit the high temperature signal to the control panel, and the control panel will respectively open the micro pump 20, the cooling fan 21, and the electromagnetic valve at one end of the transmission pipe 14 and the shunt pipe 5. First, the air in the greenhouse 1 will be sucked in by the suction fan 3, The hot air enters the refrigeration box 15 from the transmission pipe 14 when the solenoid valve is opened, and the micro pump 20 discharges the coolant in the refrigerant box 19 into the cooling pipe 16. After the hot air passes through the cooling pipe 16, the coolant inside it absorbs the heat in the air, and the hot air is turned into cold air and then discharged through the cold air outlet hood 18, and the coolant that absorbs the heat enters the refrigerant box 19 again through the cooling pipe 16, and the heat dissipation fan 21 is used to cool the high-temperature coolant, so as to keep the low temperature state of the coolant; in the process of hot and cold air discharge, the driving motor 7 drives the threaded moving rod 8 to rotate, and the sleeve 12 moves the temperature control box 2 left and right on the threaded moving rod 8 under the drive of the thread, so that the hot air outlet hood 24 and the cold air outlet hood 18 move to discharge air in the greenhouse 1, so that the temperature distribution in the greenhouse 1 is more uniform, which reduces people's labor and improves work efficiency.
