In the embodiment of the present disclosure, an explanation is made on a scheme using an air conditioner as an execution subject.

Based on the above structure of the air conditioner, as shown in fig. 2, an embodiment of the disclosure provides a method for heat dissipation of the air conditioner, including:

S21, when the air conditioner is used for refrigerating, the air conditioner starts a refrigerant circulation loop.

S22, the air conditioner controls the start and stop of the heat exchange branch and/or the cooling liquid circulation loop according to the temperature of the electric box.

By adopting the method for heat dissipation of the air conditioner, when the air conditioner refrigerates, the air conditioner starts the refrigerant circulation loop and controls the start and stop of the heat exchange branch and/or the cooling liquid circulation loop according to the temperature of the electric box. The cooling liquid circulation loop is used for radiating the electric box, or the cooling medium circulation loop is introduced through the heat exchange branch to exchange heat with the cooling liquid circulation loop, so that the electric box is radiated, the electric box is radiated step by step based on the temperature of the electric box, and the radiating effect of the electric box is improved. And the multistage circulation loop is used for radiating heat, so that the influence of external environmental factors is small, the heat radiating effect of the mobile air conditioner is improved, and the influence of the temperature and the humidity of the external environment on the heat radiation of the electric box is reduced, so that the service life of electric elements in the electric box is prolonged.

Based on the above structure of the air conditioner, as shown in fig. 3, an embodiment of the disclosure provides a method for heat dissipation of the air conditioner, including:

S21, when the air conditioner is used for refrigerating, the air conditioner starts a refrigerant circulation loop.

S31, the air conditioner detects the temperature of the electrical box.

S32, when the temperature of the electrical box is higher than the first temperature, the air conditioner starts a cooling liquid circulation loop.

S33, when the temperature of the electrical box is higher than the second temperature, the air conditioner starts the heat exchange branch.

Wherein the second temperature is greater than the first temperature.

By adopting the method for heat dissipation of the air conditioner, which is provided by the embodiment of the disclosure, the air conditioner detects the temperature of the electrical box. When the temperature of the electrical box is higher than the first temperature, the temperature of the electrical box is relatively high, and the heat dissipation requirement of the electrical box can be met only by circulating the cooling liquid at normal temperature through the cooling liquid circulation loop, so that the cooling liquid circulation loop is opened by the air conditioner. When the temperature of the electrical box is higher than the second temperature, the electrical box is higher in temperature, and the cooling liquid circulation at normal temperature is only carried out through the cooling liquid circulation loop, so that the cooling capacity of the cooling medium in the cooling liquid circulation loop is introduced into the cooling medium circulation loop by the air conditioner on the heat exchange branch circuit to cool the cooling liquid in the cooling liquid circulation loop, and the electrical box is efficiently cooled. Based on the temperature of the electric box of the mobile air conditioner, the cooling liquid circulation loop and the on-off of the heat exchange branch are controlled step by step to radiate the electric box, so that the radiating effect of the electric box of the mobile air conditioner is improved.

Based on the above structure of the air conditioner, as shown in fig. 4, an embodiment of the disclosure provides a method for heat dissipation of the air conditioner, including:

S21, when the air conditioner is used for refrigerating, the air conditioner starts a refrigerant circulation loop.

S31, the air conditioner detects the temperature of the electrical box.

S41, when the temperature of the electrical box is greater than the first temperature, the air conditioner calculates a first temperature difference value between the temperature of the electrical box and the first temperature.

S42, the air conditioner adjusts the rotating speed of the water pump according to the first temperature difference value.

S33, when the temperature of the electrical box is higher than the second temperature, the air conditioner starts the heat exchange branch.

Wherein the second temperature is greater than the first temperature.

By adopting the method for air conditioner heat dissipation provided by the embodiment of the disclosure, when the temperature of the electrical box is greater than the first temperature, the air conditioner calculates the first temperature difference value between the temperature of the electrical box and the first temperature, and the first temperature difference value can represent the degree that the current temperature of the electrical box exceeds the first temperature, so that the air conditioner adjusts the rotating speed of the water pump according to the first temperature difference value, and the cooling capacity of the cooling liquid circulation system can be matched with the degree that the current temperature of the electrical box exceeds the first temperature, thereby improving the heat dissipation energy efficiency of the electrical box.

Optionally, the air conditioner adjusts the rotation speed of the water pump according to the first temperature difference value, including: the air conditioner determines a first target rotating speed corresponding to a first temperature difference value according to a preset first corresponding relation; the air conditioner adjusts the rotating speed of the water pump to a first target rotating speed; wherein the first temperature difference is positively correlated with the first target rotational speed.

The first correspondence relationship is a correspondence relationship between the first target rotation speed and the first temperature difference, and may be determined in any manner, for example, may be determined according to a developer or a user setting, or may be measured through experiments. The first temperature difference is positively correlated with the first target rotational speed, the greater the first temperature difference, the greater the first target rotational speed. The smaller the first temperature difference value, the smaller the first target rotational speed.

Therefore, the air conditioner can enable the first target rotating speed to be matched with the first temperature difference value, and therefore the air conditioner adjusts the rotating speed of the water pump to the first target rotating speed, accuracy of the first target rotating speed is improved, and therefore heat dissipation energy efficiency of the electric box is improved.

Optionally, the air conditioner opens the heat exchange branch, including: the air conditioner opens the second throttle valve.

Therefore, the air conditioner opens the second throttle valve, the refrigerant in the refrigerant circulation loop flows from the condenser to the second throttle valve, is throttled and depressurized by the second throttle valve, and becomes a low-temperature low-pressure gas-liquid two-phase state, and exchanges heat with the cooling liquid in the cooling liquid circulation loop in the cooler, so that the cooling liquid becomes low-temperature liquid, and enters auxiliary components in the electric box for heat dissipation.

Optionally, the air conditioner opens a second throttle valve, including: the air conditioner detects the initial temperature of the cooling liquid in the cooling liquid circulation loop; the air conditioner calculates a second temperature difference value between the temperature of the electric box and the second temperature; and the air conditioner adjusts the opening degree of the second throttle valve and/or the rotating speed of the water pump according to the second temperature difference value and the initial temperature of the cooling liquid.

Thus, as the initial temperature in the cooling liquid circulation loop can represent the current cooling capacity of the cooling liquid circulation loop, the second temperature difference value between the temperature of the electric box and the second temperature can represent the degree that the current temperature of the electric box exceeds the second temperature, namely the requirement of the electric box on the cooling capacity of the cooling liquid circulation loop. Therefore, the air conditioner detects the initial temperature of the cooling liquid in the cooling liquid circulation loop, calculates a second temperature difference value between the temperature of the electric appliance box and the second temperature, and finally adjusts the opening of the second throttle valve and/or the rotating speed of the water pump according to the second temperature difference value and the initial temperature of the cooling liquid, so that the opening of the second throttle valve and/or the rotating speed of the water pump can be matched with the current cooling capacity of the cooling liquid circulation loop and the requirement of the electric appliance box on the cooling capacity of the cooling liquid circulation loop, and the energy efficiency of heat dissipation of the electric appliance box is improved.

Optionally, the air conditioner adjusts the opening of the second throttle valve and/or the rotation speed of the water pump according to the second temperature difference value and the initial temperature of the cooling liquid, including: the air conditioner determines an initial opening degree and/or an initial rotating speed corresponding to the second temperature difference value and the initial temperature of the cooling liquid according to a preset second corresponding relation; the air conditioner adjusts the opening degree of the second throttle valve to the initial opening degree and/or adjusts the rotating speed of the water pump to the initial rotating speed.

The second correspondence relationship is a correspondence relationship between the initial opening degree and/or the initial rotation speed and the second temperature difference value and the initial temperature of the cooling liquid, and may be determined in any manner, for example, may be determined according to a developer or a user setting, or may be measured through experiments. The second temperature difference is positively correlated with the initial opening and/or the initial rotational speed. The larger the second temperature difference is, the larger the initial opening degree is, the larger the initial rotational speed is, the smaller the second temperature difference is, the smaller the initial opening degree is, and the smaller the initial rotational speed is. The initial temperature of the coolant is inversely related to the initial opening degree and/or the initial rotational speed. The higher the initial temperature, the smaller the initial opening degree, the smaller the initial rotational speed, and the lower the initial temperature, the larger the initial opening degree and the larger the initial rotational speed.

In this way, the air conditioner determines the initial opening and/or the initial rotating speed corresponding to the second temperature difference and the initial temperature of the cooling liquid according to the preset second corresponding relation, so that the initial opening and/or the initial rotating speed can be matched with the second temperature difference and the initial temperature of the cooling liquid, and the accuracy of the initial opening and/or the initial rotating speed is improved. The air conditioner adjusts the opening of the second throttle valve to the initial opening and/or adjusts the rotating speed of the water pump to the initial rotating speed, so that the energy efficiency of heat dissipation of the electric box is improved.

Optionally, after the air conditioner adjusts the opening of the second throttle valve to the initial opening and/or adjusts the rotation speed of the water pump to the initial rotation speed, the air conditioner further includes: the air conditioner detects environmental parameters of a space where the air conditioner is located and/or the moving speed of the air conditioner; the air conditioner corrects the initial opening degree and/or the initial rotating speed according to the environmental parameters and/or the moving speed of the air conditioner to obtain a target opening degree and/or a second target rotating speed; the air conditioner adjusts the opening degree of the second throttle valve to a target opening degree and/or adjusts the rotating speed of the water pump to a second target rotating speed.

Wherein, the air conditioner may correct one or both of the initial opening degree and the initial rotational speed according to one or both of the environmental parameter and the moving speed of the air conditioner. For example, the air conditioner corrects the initial opening degree and the initial rotation speed according to the environmental parameter; or the air conditioner corrects the initial opening and the initial rotating speed according to the moving speed of the air conditioner; or the air conditioner corrects the initial opening degree, the initial rotating speed and the like according to the environmental parameters and the moving speed. The air conditioner may correct the initial opening degree and/or the initial rotational speed according to the environmental parameter and/or the moving speed of the air conditioner by any method. For example, according to a preset third corresponding relation, determining a compensation opening degree and/or a compensation rotating speed corresponding to the environmental parameter and/or the moving speed of the air conditioner, and determining the sum of the compensation opening degree and the initial opening degree as a target opening degree and/or determining the sum of the compensation rotating speed and the initial rotating speed as a second target rotating speed; according to a preset fourth corresponding relation, determining a first coefficient and/or a second coefficient corresponding to the environmental parameter and/or the moving speed of the air conditioner, and determining the product of the first coefficient and the initial opening as a target opening and/or determining the sum of the second coefficient and the initial rotating speed as a second target rotating speed; etc. The third and fourth correspondence may be determined in any manner, for example, according to a developer or user setting, or may be measured experimentally.

The environmental parameters include any parameters affecting the heat dissipation of the electrical box, such as temperature, humidity, etc. The moving speed is inversely related to the target opening degree and the second target rotation speed, the faster the moving speed, the smaller the target opening degree, the lower the second target rotation speed, the slower the moving speed, the greater the target opening degree, and the higher the second target rotation speed.

In this way, the air flow rate around the air conditioner can be fast in the moving process of the air conditioner, so that the heat dissipation of the electric box is influenced. Therefore, the air conditioner detects the environmental parameter of the space where the air conditioner is located and/or the moving speed of the air conditioner, corrects the initial opening and/or the initial rotating speed according to the environmental parameter and/or the moving speed of the air conditioner to obtain the target opening and/or the second target rotating speed, and finally adjusts the opening of the second throttle valve to the target opening and/or adjusts the rotating speed of the water pump to the second target rotating speed. The opening of the second throttle valve and the rotating speed of the water pump are corrected from two dimensions of the moving speed of the air conditioner and the environmental parameters, so that the influence of the moving speed of the air conditioner and the environmental parameters on the heat dissipation of the electric box is considered, and the heat dissipation effect of the electric box is improved.

Optionally, the air conditioner controls the start and stop of the heat exchange branch and/or the cooling liquid circulation loop according to the temperature of the electrical box, and the air conditioner further comprises: when the temperature of the electric box is smaller than the third temperature, the air conditioner closes the heat exchange branch; when the temperature of the electric box is smaller than the fourth temperature, the air conditioner closes the cooling liquid circulation loop; wherein the third temperature is greater than the fourth temperature.

Therefore, when the temperature of the electrical box is smaller than the third temperature, the heat dissipation requirement of the electrical box can be met only by circulating the cooling liquid through the cooling liquid circulating path, and therefore the air conditioner closes the heat exchange branch circuit to reduce energy consumption. When the temperature of the electric box is smaller than the fourth temperature, the temperature of the electric box is lower at the moment, and heat dissipation is not needed, so that the air conditioner closes the cooling liquid circulation loop.
