Referring to fig. 4, a first embodiment of a heat dissipation control method of a refrigeration apparatus according to the present invention is provided, in which the refrigeration apparatus includes an electronic control module, a liquid storage device, and a heat sink, and the liquid storage device and the electronic control module exchange heat through the heat sink; the refrigerating device also comprises a driving device in driving connection with the radiator, the driving device drives the radiator to move relative to the liquid storage device, and the heat dissipation control method of the refrigerating device comprises the following steps:
step S10, acquiring the temperature of an electric control module in the refrigerating device;
the temperature of the electric control module can be detected by a temperature sensor arranged in the electric control box or on the surface of the electric control box, and the temperature of the electric control module can be acquired in real time so as to reduce the condensation risk of the electric control module in real time.
The temperature of the electric control module in the refrigeration device can be obtained at regular time, the regular obtaining can be realized through time intervals, and the time intervals between the temperatures of the electric control modules obtained each time can be equal or different; for example, if the time intervals are equal and the temperature of the electronic control module can be obtained at intervals of 5min, or the time intervals are unequal, the temperature of the electronic control module can be obtained once every 5 minutes and then once every 7 minutes, the temperature of the electronic control module can be updated at the time intervals, for example, the obtained times that the temperature of the electronic control module is normal are greater than the preset times, the time intervals are increased, the obtained temperature of the electronic control module is normal can mean that the temperature of the electronic control module is less than the preset temperature and greater than the dew point temperature, the preset temperature is greater than the dew point temperature, and the preset temperature can be the maximum temperature of the electronic; the time interval may also be calculated by a preset algorithm or model, for example, the algorithm may be a random number algorithm.
Step S20, obtaining the dew point temperature corresponding to the outdoor environment of the refrigeration device;
the dew point temperature of the outdoor environment can be calculated through the ambient temperature and the ambient humidity, the ambient temperature can be detected through a temperature sensor arranged on the outdoor unit, the ambient humidity can be detected through a fresh air pipeline or a humidity sensor of the outdoor unit, and the temperature sensor and the humidity sensor can be integrated into one sensor.
It is understood that the ambient temperature and the ambient humidity may also be detected by other devices, or the ambient temperature and the ambient humidity may also be obtained by a weather forecast, a current weather forecast is obtained by a server or other terminals, and the current ambient temperature and the current ambient humidity are obtained according to the weather forecast.
And step S30, when the temperature of the electronic control module is lower than the dew point temperature, controlling the driving device to drive the radiator to move relative to the liquid storage device so as to increase the distance between the radiator and the liquid storage device or reduce the contact area between the radiator and the liquid storage device.
The moving manner of the step S30 may include multiple manners, and the heat sink is driven to move parallel to the liquid storage device, so as to reduce the contact area between the heat sink and the liquid storage device;
or the radiator is driven to move away from the liquid storage device, so that the distance between the radiator and the liquid storage device is increased.
The radiator and the liquid storage device can move in parallel, and the contact area between the radiator and the liquid storage device can be adjusted by moving the radiator due to the fact that the liquid storage device is cylindrical; the driving radiator is far away from the liquid storage device to move, the farther the radiator is away from the liquid storage device, the larger the thermal resistance is, and the lower the heat exchange efficiency is. The liquid storage device described in this embodiment can be a compressor or a liquid storage tank connected with the return air port of the compressor.
The radiator and the liquid storage device can be connected in a sliding mode through a sliding structure, the driving device drives the sliding device to drive the radiator to move, and the sliding device can comprise a sliding rail arranged on the liquid storage device or a sliding groove arranged on the radiator; also can be a chute arranged on the liquid storage device and a slide rail arranged on the radiator. It will be appreciated that the heat sink and the reservoir may be connected by other means, such as a rolling connection or a rotational connection via a rotational device.
When the driving device is controlled to move, the driving device can be controlled to move according to a preset distance value, and can also be controlled to move according to the temperature difference between the temperature of the electric control module and the dew point temperature, a motor in the driving device can be a stepping motor, and the step number of the stepping motor can be obtained according to the distance value.
It can be understood that, because the temperature change from high to low in the liquid storage device is small, after the driving device drives the heat radiator to move relative to the liquid storage device, if the temperature of the electronic control module is still less than the dew point temperature, the heating device in the electronic control module can be controlled to heat the electronic control module or adjust the operating parameters of the refrigeration device to increase the return air temperature of the liquid storage device. The return air temperature of the liquid storage device can be increased by increasing the opening of the expansion valve and/or reducing the rotating speed of the indoor fan.
It can be understood that, when the operation parameter of the refrigeration device is adjusted, the refrigeration and the heating of the refrigeration device are affected, and the refrigeration requirement or the heating requirement needs to be considered when the operation parameter is adjusted, then after the operation parameter of the refrigeration device is adjusted for a preset time interval, the return air temperature of the refrigeration device can be obtained, the return air temperature is compared with the set temperature to determine whether the current operation parameter meets the refrigeration or heating requirement of the user (for example, if the return air temperature is greater than the set temperature in the refrigeration mode, the refrigeration requirement is not met, and if the return air temperature is less than the set temperature in the heating mode, the heating requirement is not met), when the current operation parameter is met, the current operation parameter is maintained, and when the current operation parameter is not met, the operation parameter. It should be understood that other control methods may be used to meet the cooling or heating requirements of the user, and are not described herein.
In the technical scheme disclosed in this embodiment, when the temperature of the electronic control module is less than the dew point temperature, the control driving device drives the radiator to move relative to the liquid storage device, so as to reduce the heat exchange amount between the radiator and the liquid storage device, improve the temperature of the radiator, further improve the temperature of the electronic control module tightly attached to the radiator, and avoid condensation of the electronic control module.
Further, referring to fig. 5, a second embodiment of the refrigeration apparatus control method according to the present invention is provided based on the first embodiment, and in this embodiment, step S30 includes:
step S31, when the temperature of the electric control module is smaller than the dew point temperature, the moving distance of the radiator is obtained;
and step S32, controlling the driving device to drive the radiator to move relative to the compressor according to the moving distance.
The moving distance may be a preset moving distance or may be obtained according to a temperature difference, that is, step S31 includes: acquiring a preset moving distance; or acquiring a difference value between the temperature of the electronic control module and the dew point temperature, and determining the moving distance of the radiator according to the difference value.
After the heat radiator moves for the preset distance, the temperature of an electric control module in the refrigerating device can be continuously obtained at regular time to determine whether the heat radiator needs to continuously move, namely the moving distance and a target position corresponding to the current position are obtained; and when the target position does not exceed the limit position, controlling the driving device to drive the radiator to move to the target position, and when the target position exceeds the limit position, controlling a heating device in the electronic control module to operate, or adjusting the operating parameters of the refrigerating device to improve the return air temperature of the liquid storage device. It can be understood that the driving device may be controlled to drive the radiator to move to the extreme position, and then the heating device in the electronic control module is controlled to operate, or the operation parameter of the refrigeration device is adjusted to increase the return air temperature of the liquid storage device.
When the radiator and the liquid storage device move in parallel, the limit position is the position with the smallest contact area between the radiator and the liquid storage device, if the contact area between the radiator at the target position and the liquid storage device is smaller than that of the limit position, the target position is not beyond the limit position, and if the contact area between the radiator at the target position and the liquid storage device is equal to that of the limit position, the target position is beyond the limit position; when the radiator and the liquid storage device move relatively, the limit position is the position with the farthest distance between the radiator and the liquid storage device, if the distance between the radiator at the target position and the liquid storage device is smaller than or equal to the distance of the limit position, the target position does not exceed the limit position, and if the distance between the radiator at the target position and the liquid storage device is larger than the distance of the limit position, the target position exceeds the limit position.
Alternatively, it can be understood by those skilled in the art that when the temperature of the electronic control module is less than the dew point temperature, the operating parameters of the refrigeration device may be adjusted to increase the return air temperature of the liquid storage device, and step S10 is continuously executed after a preset time interval, and when the temperature of the electronic control module is still less than the dew point temperature, the driving device is controlled to drive the heat sink to move relative to the liquid storage device, so as to increase the distance between the heat sink and the liquid storage device or decrease the contact area between the heat sink and the liquid storage device.
When the moving distance of the radiator is determined according to the difference between the temperature of the electronic control module and the dew point temperature, a difference interval corresponding to the difference can be obtained, the moving distance corresponding to the difference interval is determined, and the radiator moves according to the movement.
According to the technical scheme disclosed by the embodiment, the heat exchanger is prevented from being moved too much at one time according to the moving distance, so that the temperature of the electric control module is prevented from being too high.
Further, a third embodiment of the refrigeration apparatus control method according to the present invention is provided based on the first or second embodiment, and in this embodiment, after step S10, the method further includes:
when the temperature of the electronic control module is less than or equal to the preset temperature, the step S20 is executed, that is, the dew point temperature corresponding to the outdoor environment of the refrigeration device is obtained.
When the temperature of the electronic control module is higher than the preset temperature, controlling the driving device to drive the radiator to move relative to the liquid storage device so as to reduce the distance between the radiator and the liquid storage device or increase the contact area between the radiator and the liquid storage device;
or when the temperature of the electric control module is higher than the preset temperature, adjusting the operating parameters of the refrigerating device to reduce the return air temperature of the liquid storage device.
Controlling the driving device to drive the compressor to move relative to the liquid storage device to increase the heat exchange amount between the radiator and the compressor may include: driving the radiator to move in parallel relative to the liquid storage device so as to increase the contact area between the radiator and the liquid storage device; or the radiator is driven to move towards the liquid storage device, so that the distance between the radiator and the liquid storage device is reduced. For a specific implementation, reference is made to the first embodiment, which is not described herein again.
When the temperature of the electric control module is high, the electric control module may be caused to malfunction, the temperature of the electric control module must be ensured not to be too high, when the temperature of the electric control module is obtained, whether the temperature of the electric control module is higher than a preset temperature or not can be judged, and the condensation condition is considered when the temperature of the electric control module is lower than or equal to the preset temperature; when the temperature of the electronic control module is higher than the preset temperature, the surface temperature of the electronic control module can be reduced, for example, the electronic control module is cooled by a cooling device, the heat exchanger can be moved to reduce the temperature of the electronic control module, or auxiliary heat dissipation devices such as a fan and the like can be started to dissipate heat, or the heat radiator is driven to move towards the liquid storage device, so that the distance between the heat radiator and the liquid storage device is reduced.
The purpose of reducing the return air temperature can be achieved by adjusting the rotating speed of the fan and the opening degree of the expansion valve, and it can be understood that a cooling device can be added to the return air pipeline to reduce the return air temperature so as to achieve the purpose of adjusting the return air temperature. For example, the return air temperature can be reduced by increasing the opening of the expansion valve and/or reducing the rotating speed of the indoor fan.
When the refrigerating device operates in a refrigerating mode, the rotating speed of the indoor fan can be directly reduced, the rotating speed of the indoor fan can be reduced, the heat exchange quantity of the indoor heat exchanger can be reduced, the temperature of a refrigerant at the outlet of the indoor heat exchanger can be reduced, and the rotating speed of the indoor fan can be directly reduced for a single-cooling refrigerating device model without considering the operation mode of the refrigerating device; for a cold-hot air conditioner, because the flow directions of the refrigerants in the refrigerating mode and the heating mode are opposite, the temperature of the refrigerant at the outlet of the indoor heat exchanger needs to be reduced in the refrigerating mode, and the temperature of the refrigerant at the outlet of the outdoor heat exchanger needs to be reduced in the heating mode, so that the operation mode of the refrigerating device is obtained; when the operation mode of the refrigerating device is a refrigerating mode, reducing the rotating speed of an indoor fan of the refrigerating device; and when the operation mode of the refrigerating device is a heating mode, reducing the rotating speed of an outdoor fan of the refrigerating device.
The opening degree of the expansion valve can be increased while the rotating speed of the indoor fan is reduced, and the return air temperature can be reduced by increasing the opening degree of the expansion valve because the refrigerant in the flow path is increased after the opening degree of the expansion valve is increased, no matter the refrigerating device is in a refrigerating or heating mode.
It can be understood that the rotation speed of the fan may be adjusted first, and then the opening degree of the expansion valve is adjusted, it can be understood that after the rotation speed of the indoor fan is reduced (or the rotation speed of the outdoor fan is reduced) for a preset time period, the step S10 may be executed again, and when the temperature of the electronic control module is greater than the preset temperature, the opening degree of the expansion valve is increased; alternatively, after increasing the opening degree of the expansion valve for a preset time period, the process may return to step S10, and when the temperature of the electronic control module is greater than the preset temperature, the indoor fan speed is decreased (or the outdoor fan speed is decreased).
In the technical scheme disclosed in this embodiment, whether direct judgement indoor ambient temperature is greater than preset the temperature, is greater than when presetting the temperature and cools down electrical control module, avoids electrical control module high temperature to break down.
