detecting whether the environmental humidity meets a target humidity or not under the condition that the environmental temperature is lower than the target temperature, wherein if the environmental humidity is higher than the target humidity, the environmental humidity is adjusted to the target humidity, and then the environmental temperature is adjusted to the target temperature; and if the environment humidity is lower than the target humidity, adjusting the environment temperature and the environment humidity simultaneously.
2. The system of claim 1, wherein the controller is further configured to: under the condition that the ambient temperature is higher than the target temperature, adjusting the temperature of the heat exchange working medium to the target temperature; and adjusting the opening degree of the heat exchange working medium adjusting valve according to the difference value between the target temperature and the environment temperature.
3. The system of claim 1, further comprising:
a heater for increasing the ambient temperature;
the controller is used for turning on the heater under the condition that the ambient temperature is lower than the target temperature.
4. The system of claim 1, further comprising:
a humidifier for increasing the ambient humidity;
the controller is used for starting the humidifier under the condition that the environmental humidity is lower than the target humidity.
5. The system according to any one of claims 1 to 4, wherein the environment detection means comprises:
temperature detection means for detecting an ambient temperature of the target space;
and the humidity detection device is used for detecting the environmental humidity of the target space.
6. The system according to any one of claims 1 to 4, further comprising:
the fan is used for supplying air to the target space;
and the controller is used for determining the air supply amount of the fan according to the difference value between the ambient temperature and the target temperature.
7. An environment control method based on the environment control system of any one of claims 1 to 6, the method comprising:
detecting whether the ambient temperature is higher than a target temperature;
under the condition that the environmental temperature is higher than the target temperature, firstly adjusting the environmental temperature to be the target temperature, and then adjusting the environmental humidity to be the target humidity;
detecting whether the environmental humidity meets a target humidity or not under the condition that the environmental temperature is lower than the target temperature, wherein if the environmental humidity is higher than the target humidity, the environmental humidity is adjusted to the target humidity, and then the environmental temperature is adjusted to the target temperature; and if the environment humidity is lower than the target humidity, adjusting the environment temperature and the environment humidity simultaneously.
