Example Taking dairy farming as an example, dairy cows are cold-resistant but not heat-resistant, but there is a certain limit to cold. Generally, the most suitable living temperature for dairy cows is 12℃ to 14℃. When the temperature of the lactating dairy cow shed is higher than 24℃ or lower than minus 4℃, the milk production will decrease. In order to achieve the above breeding conditions, the temperature of the cow shed is adjusted to between 12℃ and 18℃ through this device. Its working logic is described as follows:

1. Summer working condition: when the indoor temperature is greater than 25°C, the cooling mode of the ground source heat pump unit 5 is turned on to cool the cowshed. When the temperature reaches 18°C, the cooling mode is stopped;

2. Winter working conditions: When the indoor temperature is lower than 10°C, turn on the heating mode of the ground source heat pump unit 5 to heat the cowshed. When the temperature reaches 18°C, stop the heating mode.
