For example, the temperature inside the greenhouse body 100 can be adjusted by setting an upper limit temperature and a lower limit temperature. Specifically, the real-time temperature monitored by the temperature sensor 231 is compared with a set upper limit temperature or a set lower limit temperature, and if the real-time temperature is greater than the upper limit temperature, the central controller 232 sends a control instruction to control the ventilation fan 212 to be opened and the ventilation hole 213 to be opened, and the opening degrees of the first heat exchange medium flow regulating valve 201 and the second heat exchange medium flow regulating valve 202 are appropriately reduced to reduce the temperature in the greenhouse body 100, so that the real-time temperature is lower than the upper limit temperature.
