An embodiment of the invention provides refrigeration equipment, a temperature and humidity adjusting method and a device capable of accurately adjusting temperature and humidity, which avoid passive temperature adjustment in the humidity adjusting process and avoid excessively low temperature in the refrigeration equipment, thereby being beneficial to storage and improving the use experience of users.
The refrigerating device 100 of the present embodiment may be a refrigerator, a freezer, a wine cabinet, etc., and the following embodiments take a wine cabinet applied in a home environment as an example, illustrate a temperature and humidity adjustment method of the wine cabinet, and achieve better storage effects on wine and cigars, especially an environment with constant temperature and humidity and small fluctuation of temperature and humidity.
The refrigeration apparatus 100 includes a refrigeration compartment 101 for refrigerating an article, an evaporation compartment 102, a compartment temperature detection module 5 for obtaining a temperature of the refrigeration compartment 101, a compartment humidity detection module 4 for obtaining a humidity of the refrigeration compartment 101, an evaporation temperature detection module 3 for obtaining a temperature of the evaporation compartment 102, and a refrigeration system including an evaporator 10 provided in the evaporation compartment 102.
Fig. 1 is a schematic diagram of a temperature and humidity adjustment method according to an embodiment of the present application, and although the present application provides the method operation steps described in the following embodiment or flowchart, the method is based on conventional or non-creative labor, and there is no logically necessary causal relationship in the steps, and the execution sequence of the steps is not limited to the execution sequence provided in the embodiment of the present application.
Specifically, the method comprises the following steps:
step 101: acquiring the room temperature and the room humidity of the refrigeration room 101;
step 102: calculating a dew point temperature according to the compartment temperature and the compartment humidity;
step 103: and when the room temperature is within a preset temperature interval and the room humidity is higher than the preset humidity interval, acquiring the evaporation temperature in the evaporation room 102, and controlling the evaporation temperature to be lower than the dew point temperature and the room temperature to be within the preset temperature interval.
By the method, the temperature and the humidity in the refrigeration equipment 100 can be kept constant better, particularly when the humidity is too high, the humidity is only reduced, the fluctuation of the humidity is reduced, the final temperature and the humidity reach a stable state, the passive temperature regulation in the humidity regulation process is avoided, the humidity in the refrigeration equipment 100 is prevented from being too low, the storage is facilitated, and the use experience of a user is improved.
In step 101, chamber humidity refers to relative humidity, and both chamber temperature and chamber humidity may be obtained by the sensor.
In step 102, the dew point temperature may be calculated according to the chamber temperature and the chamber humidity by means of a table lookup, or the corresponding value may be calculated by a built-in formula.
For example, the current temperature is 0 ℃, the humidity is 50%, the corresponding saturated vapor pressure is determined according to the current temperature, the current vapor pressure is calculated according to the saturated vapor pressure and the humidity, and the corresponding temperature value is determined when the current vapor pressure is saturated, and the temperature value is the dew point temperature.
In step 103, the evaporation temperature of the surface of the evaporator 10 in the evaporation chamber 102 is obtained. The current refrigeration state of the evaporator 10 can be more intuitively and accurately embodied.
Further, in one embodiment, step 103 includes:
outputting a signal of decreasing the opening degree to an electronic expansion valve for controlling the evaporator 10;
a signal to decrease the rotation speed is output to the evaporation fan 20.
In another embodiment, step 103 includes:
outputting a signal for increasing the rotation speed to the compressor;
a signal to decrease the rotation speed is output to the evaporation fan 20.
A signal for decreasing the opening degree is output to the electronic expansion valve for controlling the evaporator 10, and a signal for increasing the rotation speed is output to the compressor. The temperature of the surface of the evaporator 10 can be reduced in both modes, the electronic expansion valve outputs a reduced opening degree, so that the pressure difference at two ends of the evaporator 10 is increased, more refrigerant is gasified, the refrigerating capacity of the evaporator 10 is improved, and the temperature is reduced; the increase in the rotational speed of the compressor can increase the refrigeration capacity of the system, further reducing the temperature of the evaporator 10 to a temperature less than the dew point temperature. The saturated steam pressure in the evaporation chamber is reduced, the steam is more easily condensed and separated out, and then frost is formed in the evaporation chamber, so that the quantity of the steam on the whole loop is reduced.
The signal for decreasing the rotation speed is output to the evaporation fan 20, so that the heat transfer between the refrigerating compartment 101 and the evaporation compartment 102 is reduced, and the lower the rotation speed of the evaporation fan 20 is, the smaller the heat exchange amount is, so that the temperature of the evaporator 10 is reduced, and the temperature of the refrigerating compartment 101 is reduced as little as possible.
The heat exchange between the refrigerating room and the evaporating room is reduced, so that the temperature reduction amount is small, but the vapor in the refrigerating room is condensed and separated out in the evaporating room, and the air returned to the refrigerating room is drier, so that the humidity is reduced, and finally, the humidity of the air is reduced under the condition that the temperature in the refrigerating room is little fluctuated, namely, the influence on the temperature fluctuation is reduced while dehumidification is performed.
Further, the step 103 further includes:
and in the process of controlling the evaporation temperature to be lower than the dew point temperature, outputting a signal for increasing the rotation speed to the evaporation fan 20 when the room temperature is higher than the highest temperature threshold. That is, if the refrigerating compartment 101 itself has a refrigerating demand, the evaporator fan 20 can continue to supply cold energy to the refrigerating compartment 101 so that the temperature of the refrigerating compartment 101 is kept as stable as possible, while reducing heat exchange between the refrigerating compartment 101 and the evaporating compartment 102.
And, step 103 further comprises:
and in the process of controlling the evaporation temperature to be lower than the dew point temperature, outputting a rotating speed reducing signal to the evaporation fan 20 when the room temperature is lower than a temperature minimum threshold. That is, if the temperature in the refrigerating compartment 101 is further reduced in addition to reducing the heat exchange between the refrigerating compartment 101 and the evaporating compartment 102 by the evaporating fan 20, the fan rotation speed is further reduced, the heat exchange amount between the evaporating compartment 102 and the refrigerating compartment 101 is further reduced, and the temperature of the refrigerating compartment 101 is kept as stable as possible.
Further, the method further comprises the steps of:
and when the humidity of the compartment is in the preset humidity range, controlling the evaporation temperature not to be lower than the dew point temperature.
This prevents condensation of water vapor in the evaporation compartment 102 when the temperature and humidity are no longer regulated, and reduces the humidity of the refrigeration compartment 101, so that the humidity of the system is ensured to be constant when the evaporation temperature is maintained not lower than the dew point temperature.
