Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Fig. 1 is a schematic view of an air conditioning system for dissipating heat of an electric controller through a refrigerant according to some embodiments of the present disclosure.
As shown in fig. 1, the air conditioning system includes a compressor 1, an oil separator 2, a four-way valve 3, an outdoor heat exchanger 4, a refrigerant heat dissipation module 5, a throttling part 6 of the refrigerant heat dissipation module 5, an indoor heat exchanger 8, a throttling part 7 of the indoor heat exchanger 8, and a gas-liquid separator 9. In addition, the air conditioning system further includes various electric controllers (not shown in fig. 1), such as a driving board. A refrigerant heat dissipation module 5 is arranged around (for example, behind) an electric controller which needs heat dissipation, and the electric controller dissipates heat through the refrigerant heat dissipation module 5. The refrigerant flow passing through the refrigerant heat dissipation module 5 can be controlled by adjusting the opening of the throttling part 6. The air conditioning system also comprises means (not shown in fig. 1) for adjusting the temperature of the electric controller, which means adjust the opening of the throttling member 6 according to the temperature of the electric controller and the ambient temperature, and in addition, in combination with the ambient humidity.
Fig. 2 is a schematic flowchart of a method for adjusting a temperature of an electric controller based on an ambient temperature according to some embodiments of the present disclosure. The method may be performed, for example, by a device that adjusts the temperature of an electrical controller.
As illustrated in fig. 2, the method of this embodiment includes:
in step S21, the electric controller temperature and the ambient temperature are acquired.
The temperature of the electric controller and the ambient temperature can be detected by a temperature sensor, and transmitted to a device for adjusting the temperature of the electric controller.
In step S22, the electric controller temperature and the ambient temperature are compared.
In step S23, the opening degree of the throttling element 6 is adjusted according to the comparison result between the temperature of the electric controller and the ambient temperature, so that the consistency between the temperature of the electric controller and the ambient temperature meets the preset requirement.
In some embodiments, adjusting the opening degree of the throttling member 6 comprises:
under the condition that the temperature of the electric controller is higher than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds a first threshold value, the opening degree of the throttling part 6 is increased, more refrigerants pass through the refrigerant heat dissipation module 5, and the temperature of the electric controller is reduced more quickly. The first threshold may be set as required for control accuracy, for example, to 0.1 degrees celsius. As a specific example, the first threshold may be 0 degrees celsius.
Under the condition that the temperature of the electric controller is smaller than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the second threshold value, the opening degree of the throttling part 6 is reduced, less refrigerants pass through the refrigerant heat dissipation module 5, and the temperature of the electric controller is enabled to be close to the ambient temperature more quickly. The second threshold may be set as required for control accuracy, for example, to 0.1 degrees celsius. As a specific example, the second threshold may be 0 degrees celsius.
Under the condition that the temperature of the electric controller is equal to the ambient temperature, the opening degree of the throttling part 6 is kept, namely the flow rate of the refrigerant is proper, and the flow rate of the refrigerant can not be changed.
And keeping the opening degree of the throttling component 6 under the conditions that the temperature of the electric controller is higher than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature does not exceed a first threshold value.
And keeping the opening degree of the throttling component 6 under the conditions that the temperature of the electric controller is less than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature does not exceed a second threshold value.
Under the ideal state, the temperature of the electric controller is equal to the ambient temperature, and condensation is not easy to generate at the moment. Or the difference between the temperature of the electric controller and the ambient temperature is controlled within a reasonable small range, and the probability of generating condensation can be greatly reduced. Thereby avoiding the short circuit or burning of the electric controller caused by condensation.
Fig. 3 is a schematic flowchart of a method for adjusting a temperature of an electric controller based on an ambient temperature according to some embodiments of the present disclosure. The method may be performed, for example, by a device that adjusts the temperature of an electrical controller.
As illustrated in fig. 3, the method of this embodiment includes:
in step S31, the electric controller temperature and the ambient temperature are periodically acquired.
In step S32, the electric controller temperature and the ambient temperature are periodically compared.
In step S33, if the temperature of the electric controller is greater than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the first threshold value in the current adjustment period, the opening degree of the throttling element 6 is increased to the first opening degree a.
The first opening a is, for example, a 50% maximum opening, but the disclosure does not limit the specific value of the first opening a.
Therefore, the flow of the refrigerant is increased, the temperature of the electric controller is reduced, and the temperature of the electric controller is basically close to the ambient temperature.
In step S34, if the temperature of the electric controller is less than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the second threshold value in the current adjustment period, the opening degree of the throttling member 6 is decreased to the third opening degree n.
The third opening degree n may be, for example, a minimum opening degree of the throttle member 6. The third opening degree n is, for example, a 10% maximum opening degree, but the present disclosure is not limited to a specific numerical value of the third opening degree n.
Therefore, the flow of the refrigerant is reduced, the temperature of the electric controller is basically close to the ambient temperature, the condition that the temperature is too low when the electric controller dissipates heat is avoided as much as possible, condensation generated by the electric controller is further avoided, and short circuit or burning of the electric controller caused by the condensation is avoided.
In step S35, after step S33, if the electric controller temperature is greater than the ambient temperature and the difference between the electric controller temperature and the ambient temperature exceeds a first threshold value in the next adjustment cycle, the opening degree of the throttling part 6 is increased to a second opening degree m, wherein the first opening degree a is smaller than the second opening degree m.
The second opening degree m may be, for example, a maximum opening degree of the throttle 6, i.e., a 100% maximum opening degree, but the present disclosure is not limited to a specific value of the second opening degree m.
Therefore, under the condition that the temperature of the electric controller is continuously higher than the ambient temperature in the continuous adjusting period, the adjusting and controlling force is increased, the flow of the refrigerant is increased, the temperature of the electric controller is reduced as soon as possible, and the temperature of the electric controller is basically close to the ambient temperature.
In step S36, after step S33, in case the electric controller temperature is less than the ambient temperature and the difference between the electric controller temperature and the ambient temperature exceeds the second threshold value in the next adjustment cycle, the opening degree of the throttling part 6 is decreased to a fourth opening degree b, wherein the fourth opening degree b is in the opening degree range between the first opening degree a and the third opening degree n.
For example, the fourth opening b is (the first opening a + the third opening n)/2.
Therefore, when the overshoot occurs, the flow rate of the refrigerant is adjusted back. In addition, in the process of adjusting back, the opening degree of the adjusting back can be selected to be within the opening degree range between the first opening degree a and the third opening degree n, so that the flow rate of the refrigerant is changed stably, and the condensation caused by the drastic change of the flow rate of the refrigerant is prevented.
In step S37, the opening degree of the throttling element 6 is continuously adjusted according to S33-S36 until the temperature of the electric controller is substantially close to the ambient temperature, and the opening degree of the throttling element 6, that is, the flow rate of the refrigerant is kept appropriate, without changing the flow rate of the refrigerant.
The condition that the temperature of the electric controller is basically close to the ambient temperature comprises the following steps: the temperature of the electric controller is equal to the ambient temperature, the temperature of the electric controller is greater than the ambient temperature, the difference between the temperature of the electric controller and the ambient temperature is not more than a first threshold value, the temperature of the electric controller is less than the ambient temperature, and the difference between the temperature of the electric controller and the ambient temperature is not more than a second threshold value.
Fig. 4 is a schematic flowchart of a method for adjusting a temperature of an electric controller based on an ambient temperature and an ambient humidity according to some embodiments of the present disclosure. The method may be performed, for example, by a device that adjusts the temperature of an electrical controller. The parameters such as the threshold and the opening (e.g. a, b, m, n) of this embodiment are the same as those of the previous embodiment, and are not described herein again.
As illustrated in fig. 4, the method of this embodiment includes:
in step S41, the electric controller temperature, the ambient temperature, and the ambient humidity are periodically acquired.
The temperature of the electric controller and the ambient temperature can be detected by a temperature sensor, and transmitted to a device for adjusting the temperature of the electric controller. The ambient humidity may be detected, for example, by a humidity sensor and transmitted to a device for regulating the temperature of the electrical controller.
In step S42, the electric controller temperature and the ambient temperature are periodically compared.
In step S43, the opening degree of the throttling member 6 is adjusted according to the comparison result between the temperature of the electric controller and the ambient temperature and the ambient humidity. See steps S431 to S435 for an exemplary manner.
In step S431, if the temperature of the electric controller is greater than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the first threshold value in the current adjustment period, the opening degree of the throttling part 6 is increased to the first opening degree a.
In step S432, if the temperature of the electric controller is lower than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the second threshold, and the ambient humidity is not lower than the preset humidity (indicating that the environment is relatively humid and is likely to generate condensation), the opening degree of the throttling element 6 is reduced to the third opening degree n, so that the flow rate of the refrigerant is reduced, and the temperature of the electric controller is close to the ambient temperature. In addition, the frequency of a fan of the air conditioner can be increased simultaneously, so that the local environment around the electric controller becomes dry, and the probability of condensation is reduced.
In addition, in the case that the temperature of the electric controller is lower than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the second threshold, if the ambient humidity is lower than the preset humidity (indicating that the environment is dry and condensation is not easily generated), step S435 may be performed, i.e., the opening degree of the throttling part 6 is maintained.
In step S433, after step S431, if the temperature of the electric controller is greater than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds a first threshold value in the next adjustment cycle, the opening degree of the throttling part 6 is increased to a second opening degree m, wherein the first opening degree a is smaller than the second opening degree m.
Therefore, under the condition that the temperature of the electric controller is continuously higher than the ambient temperature in the continuous adjusting period, the adjusting and controlling force is increased, the flow of the refrigerant is increased, the temperature of the electric controller is reduced as soon as possible, and the temperature of the electric controller is basically close to the ambient temperature.
In step S434, after step S431, if the temperature of the electric controller is less than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the second threshold in the next adjustment cycle, if the ambient humidity is not less than the preset humidity, the opening degree of the throttling element 6 is decreased to a fourth opening degree b, wherein the fourth opening degree b is within the opening degree range between the first opening degree a and the third opening degree n. In addition, the frequency of the fan can be increased simultaneously, so that the local environment around the electric controller becomes dry, and the probability of condensation is reduced.
Furthermore, after step S431, if the temperature of the electric controller is less than the ambient temperature and the difference between the temperature of the electric controller and the ambient temperature exceeds the second threshold in the next adjustment cycle, if the ambient humidity is lower than the preset humidity, step S435 is performed, i.e., the opening degree of the throttling part 6 is maintained.
Therefore, when the over-adjustment occurs, whether the flow rate of the refrigerant is adjusted back or not is determined according to the environment humidity condition. If the adjustment back is determined, the opening range between the first opening a and the third opening n can be selected according to the opening of the adjustment back, so that the flow of the refrigerant is changed stably, and the condensation caused by the violent change of the flow of the refrigerant is prevented.
In step S435, the opening degree of the throttle 6 is maintained.
According to automatically controlled ware temperature and ambient temperature to combine ambient humidity to adjust refrigerant flow, the temperature that appears when can avoiding automatically controlled ware heat dissipation as far as possible is crossed the condition excessively, and then avoids the condensation that produces from this, thereby avoids the automatically controlled ware short circuit or burn out that the condensation leads to.
