step S10, acquiring the temperature of an electric control module in the refrigerating device at regular time;
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 electric control module is lower than the dew point temperature, increasing the heating power of the heating device.
Increasing the heating power of the heating device comprises starting the heating device, and starting the heating device to increase the heating power of the heating device from zero to a target value so as to improve the heating power; the increase of the heating device can also be realized under the condition that the heating device is started, and the heating power of the heating device is directly increased. When the heating power is increased, the heating power can be directly increased to the preset power, the heating power can also be directly increased according to a preset adjustment value, and the power adjustment value is increased on the basis of the current heating power when the heating power is adjusted every time.
The heating device can comprise a single heating element, and the current of the heating element can be directly increased when the heating power is increased; or the heating device may comprise a plurality of heating elements, the number of heating elements that are switched on may be increased to increase the heating power of the heating device.
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 tank, 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 heating power of the heating device is increased to avoid a large power consumption of the refrigeration device.
In the technical scheme disclosed in this embodiment, when the temperature of the electronic control module is lower than the dew point temperature, the control driving device drives the radiator to move relative to the liquid storage tank so as to reduce the heat exchange amount between the radiator and the liquid storage tank, 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 heat dissipation control method for a refrigeration apparatus according to the present invention is provided based on the first embodiment, and in this embodiment, the step S30 includes:
step S31, when the temperature of the electric control module is lower than the dew point temperature, acquiring a power adjustment value of the heating device;
and step S32, increasing the heating power of the heating device according to the power adjustment value.
The power adjustment value may be a preset power adjustment value or obtained according to the temperature difference, that is, step S31 includes: acquiring a preset power adjustment value; or acquiring a difference value between the temperature of the electronic control module and the dew point temperature, and determining a power adjustment value of the heating device according to the difference value.
After adjustment is carried out according to the power adjustment value, the temperature of an electric control module in the refrigerating device can be continuously obtained at regular time to determine whether power adjustment needs to be continuously carried out or not, namely when the temperature of the electric control module is smaller than the dew point temperature, target power is obtained, when the target power is larger than preset power, the heating power of the heating device can be directly adjusted to the preset power, and the operation parameter of the refrigerating device is adjusted to increase the return air temperature; and when the target power is less than or equal to the preset power, adjusting the heating power of the heating device to the target power. Increasing the return air temperature can be achieved by reducing the rotational speed of the indoor fan or reducing the opening degree of the expansion valve.
According to the technical scheme disclosed by the embodiment, the electric control module moves according to the moving distance, and the phenomenon that the temperature of the electric control module is too high due to too much one-time adjustment of the heating power is avoided.
Further, referring to fig. 6, a third embodiment of the heat dissipation control method for a refrigeration apparatus according to the present invention is provided based on the first embodiment, and in this embodiment, after step S20, the method further includes:
step S40, when the temperature of the electric control module is lower than the dew point temperature, the target heating power of the heating device is obtained;
when the target heating power is less than or equal to a preset power, the step S30 is executed, that is, the heating power of the heating device is increased.
And when the target heating power is greater than the preset power, adjusting the operating parameters of the refrigerating device so as to improve the return air temperature of the liquid storage tank.
It can be understood that, when the target heating power is greater than the preset power, the heating power of the heating device may be adjusted to the preset power, and then the operation parameters of the refrigeration device may be adjusted to increase the return air temperature of the liquid storage tank. When the target heating power is higher than the preset power, the temperature of the electronic control module can be increased by other methods, for example, the radiator is controlled to move relative to the liquid storage tank, so that the heat exchange quantity between the heat outlet pipe and the radiator is reduced. The return air temperature of the liquid storage tank can be improved by reducing the opening degree 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.
Further, a fourth embodiment of the refrigeration apparatus control method according to the present invention is provided based on any one of the first to third embodiments, 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.
And when the temperature of the electric control module is higher than the preset temperature, reducing the heating power of the heating device.
It can be understood that when the temperature of the electronic control module is higher than the preset temperature, the temperature of the electronic control module is very high, and at the moment, the heating power can be directly turned off, so that the electric quantity loss is reduced while the temperature of the electronic control module is reduced. After the heating device is turned off, the temperature of the electric control module may still be high, and at this time, the electric control module may be cooled in other ways, that is, when the temperature of the electric control module is higher than the preset temperature, whether the heating device is turned on or not is judged; when the heating device is started, the step of reducing the heating power of the heating device is executed; and when the heating device is not started, adjusting the operation parameters of the refrigerating device so as to reduce the return air temperature of the liquid storage tank.
The preset temperature may be 75 ℃. When the heating device is not started, heating can be performed in other manners, for example, the temperature of the electronic control module is reduced through the temperature reduction device, the heat exchanger can be moved to reduce the temperature of the electronic control module, or an auxiliary heat dissipation device such as a fan can be started to dissipate heat, or the heat radiator is driven to move relative to the liquid storage tank, so that the heat exchange amount between the heat radiator and the liquid storage tank is increased. Reducing the amount of heat exchange between the heat sink and the liquid reservoir may include driving the heat sink to move parallel relative to the liquid reservoir to increase the contact area between the heat sink and the liquid reservoir; or the radiator is driven to move towards the liquid storage tank so as to reduce the distance between the radiator and the liquid storage tank; alternatively, the heat sink is driven to move downward.
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 increasing 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 increased, the rotating speed of the indoor fan can be increased, the heat exchange quantity of the indoor heat exchanger can be increased, 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 increased aiming at a single-cold 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, increasing the rotating speed of an indoor fan of the refrigerating device; and when the operation mode of the refrigerating device is a heating mode, increasing the rotating speed of an outdoor fan of the refrigerating device.
In order to avoid that the requirement of a user is not met after the wind speed is reduced, when the rotating speed of the indoor fan is increased, the rotating speed of the indoor fan is increased according to a preset rotating speed adjusting value, the return air temperature of the indoor unit is obtained after a preset time interval, and when the return air temperature is smaller than the set temperature, the step of increasing the rotating speed of the indoor fan according to the preset rotating speed adjusting value is returned to be executed until the return air temperature reaches the set temperature or the surface temperature of the electric control module reaches the preset temperature. The same principle of increasing the rotating speed of the outdoor fan is not repeated herein.
The opening degree of the expansion valve can be increased while the rotating speed of the indoor fan is increased, and after the opening degree of the expansion valve is increased, the temperature of a refrigerant throttled by the expansion valve is reduced, so that the return air temperature is reduced, and the return air temperature can be increased by increasing the opening degree of the expansion valve 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 increased (or the rotation speed of the outdoor fan is increased) 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 higher than the preset temperature, the indoor fan speed is increased (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.
