Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

In combination with FIG. 1 , as shown in FIG. 2 , FIG. 2 is a schematic flow diagram of a temperature control method provided by the present application. The temperature control method provided in the embodiment of the present application can be applied to the above-mentioned working equipment 110, data acquisition equipment 120, and A temperature control device 130 , a second temperature control device 140 and a temperature control device 150 . The temperature control method includes: S201-S203.

S201. The temperature control device determines the heat dissipation state of the working equipment.

Wherein, the heat dissipation state includes: a first state or a second state. The heat dissipation rate in the first state is smaller than the heat dissipation rate in the second state.

In a practicable manner, the method for the temperature control device to determine the heat dissipation state of the working equipment may include: the temperature control device may obtain the operating temperature of the working equipment at the time of measurement, and when the above-mentioned operating temperature is greater than or equal to the preset first temperature When the threshold is reached, it means that the operating temperature of the working equipment is too high at the measurement moment, resulting in a low heat dissipation rate, and the temperature control device can determine that the heat dissipation state of the working equipment is the first state. When the above-mentioned operating temperature is less than the preset first temperature threshold and greater than or equal to the preset second temperature threshold, it means that the operating temperature of the working equipment at the measurement moment is relatively high, which leads to a relatively high heat dissipation rate, and the temperature control device can determine The cooling state of the working equipment is the second state.

Exemplarily, the preset first temperature threshold is 30 degrees Celsius (°C), and the second temperature threshold is 26°C. When the temperature control device obtains that the operating temperature of the working equipment at the measurement moment is 30°C, which is equal to the first temperature threshold of 30°C, the temperature control device can determine that the cooling state of the working equipment is the first state. When the temperature control device acquires that the operating temperature of the working equipment at the measurement moment is 28°C, which is less than the first temperature threshold of 30°C and greater than the second temperature threshold of 26°C, the temperature control device can determine that the cooling state of the working equipment is second state.

In another practicable manner, the method for the temperature control device to determine the heat dissipation state of the working equipment may include: the temperature control device may obtain the first data and the second data respectively, and when the first data satisfies the first preset condition, The temperature control device determines that the cooling state is the first state. Wherein, the first data includes: the return air temperature of the first space where the working equipment is located, the operating temperature of the working equipment, and the preset return temperature. When the second data satisfies the second preset condition, the temperature control device determines that the cooling state is the second state. Wherein, the second data includes: the inlet air temperature of the first space where the working equipment is located, the heat load of the working equipment, the air volume threshold of the second temperature control equipment, the operating temperature of the working equipment, and the specific heat capacity of the air.

S202. When the heat dissipation state is the first state, the temperature control device runs the first temperature control device and stops running the second temperature control device.

Wherein, the operating power of the first temperature control device is greater than the operating power of the second temperature control device.

When the heat dissipation state is the first state, it means that the heat dissipation demand of the current working equipment is high, and the temperature control device can operate the first temperature control equipment with high power and good cooling effect, and stop the operation of the second temperature control equipment.

In a practicable manner, the method for the temperature control device to operate the first temperature control device may include: operating the first temperature control device according to the preset operating strategy of the first temperature control device, so that the first temperature control device can The heat dissipation requirements of the working equipment in the first state are met.

Optionally, the operating strategy of the first temperature control device may include: adjusting the operating power of the first temperature control device, and intermittently operating the first temperature control device.

Exemplarily, it is preset that the first temperature control device is a DX machine room precision air conditioner, and the second temperature control device is an intelligent fresh air system. When the temperature control device determines that the equipment is in the first state, that is, the heat dissipation demand of the current working equipment is high, the precision air conditioner in the DX machine room is run and the intelligent fresh air system is turned off.

S203. When the heat dissipation state is the second state, the temperature control device runs the second temperature control device and stops running the first temperature control device.

When the heat dissipation state is the second state, it means that the heat dissipation demand of the current working equipment is low, and the temperature control device can operate the second temperature control equipment with lower power and slightly worse cooling effect, and stop the operation of the first temperature control equipment.

In a practicable manner, the method for the temperature control device to operate the second temperature control device may include: operating the second temperature control device according to the preset operating strategy of the second temperature control device, so that the second temperature control device can The heat dissipation requirements of the working equipment in the second state are met.

Optionally, the operating strategy of the second temperature control device may include: adjusting the operating power of the second temperature control device, and intermittently operating the second temperature control device.

Exemplarily, it is preset that the first temperature control device is a DX machine room precision air conditioner, and the second temperature control device is an intelligent fresh air system. When the temperature control device determines that the equipment is in the second state, that is, the heat dissipation demand of the current working equipment is low, the intelligent fresh air system is operated and the precision air conditioner of the DX machine room is turned off.

The technical solutions provided by the above embodiments bring at least the following beneficial effects: It can be seen from S201-S203 that, firstly, the heat dissipation state of the working equipment is determined. When the cooling state is the first state, the first temperature control device is operated, and the second temperature control device is stopped. When the cooling state is the second state, the second temperature control device is operated, and the first temperature control device is stopped. Wherein, the heat dissipation rate in the first state is lower than the heat dissipation rate in the second state, and the operating power of the first temperature control device is greater than that of the second temperature control device. Therefore, when the heat dissipation rate of the working device is small, the operation of the second temperature control device can be stopped. The second temperature control device controls the temperature only through the first temperature control device with higher operating power. The device controls the temperature. In this way, temperature control equipment with high operating power is avoided for a long time, energy is saved, and the operating cost of working equipment is reduced.

In an optional embodiment, the temperature control device determines the heat dissipation state of the working equipment. On the basis of the method embodiment shown in FIG. 2, this embodiment provides a possible implementation, as shown in FIG. 3 , FIG. 3 is a schematic flow diagram II of a temperature control method provided by the present application. In S201, the method for the temperature control device to determine the heat dissipation state of the working equipment includes: S301-S302.

S301. The temperature control device acquires first data.

Wherein, the first data includes: the return air temperature of the first space where the working equipment is located, the operating temperature of the working equipment, and the preset return temperature.

Optionally, the preset hysteresis temperature may be the product of the initial hysteresis temperature and the adjustment coefficient of the working equipment.

Optionally, the first data further includes: the second cooling capacity of the first temperature control device at the measurement moment, and the second operating power of the first temperature control device at the measurement moment.

In a manner that can be implemented, referring to FIG. 1 , the method for the temperature control device to obtain the first data may include: the data acquisition device 120 monitors the return air temperature of the first space where the working equipment 110 is located in real time, and real-time or periodically The return air temperature is sent to the temperature control device 150. The temperature control device 150 can read the preset operating temperature of the working equipment 110 and the preset hysteresis temperature.

S302. When the first data satisfies the first preset condition, the temperature control device determines that the cooling state is the first state.

Wherein, the first preset condition includes: the return air temperature is greater than or equal to the first reference value.

Optionally, the first reference value is: the sum of the operating temperature and the preset hysteresis temperature.

Optionally, the preset hysteresis temperature may be the product of the initial hysteresis temperature and the adjustment coefficient. In this case, the first preset condition includes:

T≥Tc+μTd;

Among them, T is the return air temperature, Tc is the operating temperature, μ is the adjustment coefficient, and Td is the initial return temperature.

Exemplarily, the first data acquired by the preset temperature control device includes: the return air temperature of the first space where the working equipment is located is 32°C, the operating temperature of the working equipment is 28°C, and the preset return temperature is 2 °C (that is, the product of the initial hysteresis temperature of 5 °C and the adjustment coefficient of 0.4). It can be seen from the above that the first reference value is the sum of the operating temperature of 28°C and the preset return temperature of 2°C, which is 30°C, and the return air temperature of 32°C is greater than the first reference value of 30°C. Therefore, the heat dissipation speed of the working equipment at this time is smaller, the temperature control device determines that the cooling state is the first state.

The technical solution provided by the above embodiment brings at least the following beneficial effects: It can be seen from S301-S302 that after the temperature control device acquires the first data, when the first data satisfies the first preset condition, the temperature control device can determine that the heat dissipation state is first state. In this way, the temperature control device can determine the heat dissipation state of the working equipment, so that the first temperature control equipment can be operated subsequently according to the heat dissipation state.

In an optional embodiment, when the heat dissipation state is the first state, the temperature control device operates a method for the first temperature control device.
