Theoretically, the evaporation temperature of the refrigeration evaporator is adjusted to be reduced, so that the temperature of the refrigerating chamber can be directly lowered, moisture in air is condensed, and the humidity of the compartment is reduced; on the contrary, the evaporation temperature of the refrigeration evaporator is increased, so that the moisture condensation can be reduced, and the humidity control function is realized. However, in the conventional dual-temperature dual system, due to the pressure balance of the system and the characteristics of a single refrigerant, the temperature of the refrigerating chamber may be too low in the process of implementing refrigeration dehumidification by reducing the evaporation temperature of the refrigerating evaporator.
Fig. 1 schematically illustrates a refrigeration system (hereinafter, referred to as a refrigeration system) of a refrigerator with a humidity adjusting function according to the present invention, where an arrow in fig. 1 is a flowing direction of a refrigerant. The communication between the components described below may be through a conduit. The refrigerating system mainly comprises a compressor 1, a condenser 2, a gas-liquid separator 3, an evaporative condenser 4, a freezing evaporator 5, a refrigerating evaporator 6, an electronic expansion valve 7, a freezing capillary tube 9 and a humidity sensor (not shown in the figure). The humidity sensor is arranged in the refrigerating chamber and used for detecting the humidity of the refrigerating chamber. The gas-liquid separator 3 has an inlet and two outlets, which are a lower outlet and an upper outlet, respectively. The outlet of the compressor 1 communicates with the inlet of the gas-liquid separator 3 via the condenser 2. The upper outlet of the gas-liquid separator 3 is communicated with the inlet of the compressor 1 after passing through the evaporative condenser 4, the freezing capillary 9, the freezing evaporator 5 and the evaporative condenser 4 in sequence. The outlet at the lower end of the gas-liquid separator 3 is communicated with the inlet of the compressor 1 after passing through the electronic expansion valve 7, the refrigeration evaporator 6 and the evaporative condenser 4 in sequence.
The refrigerating system of the utility model adopts non-azeotropic refrigerants as the refrigerant. The refrigerant condensed by the condenser 2 enters the gas-liquid separator 3, the mixed refrigerant is separated in the gas-liquid separator 3, and the high boiling point liquid refrigerant flows out from the outlet at the lower end of the gas-liquid separator 3 and then enters the refrigeration evaporator 6 for heat exchange through the electronic expansion valve 7; the low boiling point refrigerant from the upper port of the gas-liquid separator 3 flows through the refrigeration loop of the refrigeration evaporator 5; because two non-azeotropic refrigerants are used for refrigerating together, the evaporating temperatures of the refrigerating evaporator 6 and the freezing evaporator 5 can be independently adjusted and controlled, and therefore the refrigerating temperature and the refrigerating humidity can be simultaneously guaranteed. Therefore, by adjusting the opening degree of the electronic expansion valve 7, the flow rate of the refrigerant to the refrigeration evaporator 6 can be adjusted, and the evaporation temperature of the refrigeration evaporator 6 is changed, thereby realizing the adjustment of the humidity of the refrigeration chamber.
Preferably, the outlet pipeline of the refrigerating evaporator 6 is communicated with the outlet pipeline of the freezing evaporator 5 after meeting, and then communicated with the evaporative condenser 4, and then communicated with the inlet of the compressor 1 through the evaporative condenser 4. The refrigerant that flows out in the refrigerated storage evaporimeter 6 and the refrigerant that flows out in the freezing evaporimeter 5 mix in the pipeline after crossing, and the refrigerant after the mixture exchanges heat in evaporative condenser 4 with the refrigerant that the upper end opening of vapour and liquid separator 3 flows out, improves heat exchange efficiency.
In order to realize the low temperature control of the freezing evaporator 5, a bypass is preferably added, and a bypass capillary tube 8 is arranged on the bypass and is connected with a passage formed by the electronic expansion valve 7 and the refrigerating evaporator 6 in parallel. In the preferred scheme, a pipeline at the outlet at the lower end of the gas-liquid separator 3 is divided into two paths, and one path is communicated with an inlet of the compressor 1 after sequentially passing through the electronic expansion valve 7, the refrigeration evaporator 6 and the evaporative condenser 4; one path of the liquid passes through a bypass capillary tube 8 and an evaporative condenser 4 in sequence and then is communicated with an inlet of the compressor 1. Preferably, the outlet pipeline of the bypass capillary tube 8 and the outlet pipeline of the refrigeration evaporator 6 are communicated with the evaporative condenser 4 after meeting, and then are communicated with the inlet of the compressor 1 through the evaporative condenser 4. More preferably, the outlet pipeline of the bypass capillary tube 8, the outlet pipeline of the refrigerating evaporator 6 and the outlet pipeline of the freezing evaporator 5 are converged and then communicated with the evaporative condenser 4, and then communicated with the inlet of the compressor 1 through the evaporative condenser 4.
The refrigerant condensed by the condenser 2 enters the gas-liquid separator 3, the mixed refrigerant is separated in the gas-liquid separator 3, and the high boiling point liquid refrigerant is divided into two parts after flowing out from the lower outlet of the gas-liquid separator 3: one path enters the refrigeration evaporator 6 through the electronic expansion valve 7 for heat exchange, and the other path is throttled, cooled and depressurized through the bypass capillary tube 8 and then is mixed with a refrigerant after heat exchange in the refrigeration evaporator 6; the low boiling point refrigerant from the upper port of the gas-liquid separator 3 flows through the refrigeration loop of the refrigeration evaporator 5; because two non-azeotropic refrigerants are used for refrigerating together, the evaporating temperatures of the refrigerating evaporator 6 and the freezing evaporator 5 can be independently adjusted and controlled, and therefore the refrigerating temperature and the refrigerating humidity can be simultaneously guaranteed. Therefore, the opening degree of the electronic expansion valve 7 of the refrigerant flowing through the passage of the refrigeration evaporator 6 is adjusted, the flow rate leading to the refrigeration evaporator 6 is adjusted, the evaporation temperature of the refrigeration evaporator 6 is changed, and the humidity adjustment is realized.
In addition to the above-mentioned scheme, a condensation preventing pipe 10 and/or a drying filter 11 are additionally arranged on a connecting pipeline of the inlets of the condenser 2 and the gas-liquid separator 3. The condensation preventing pipe 10 is additionally arranged, so that the condensation on the surface of the refrigerator can be effectively prevented; the addition of the dry filter 11 can filter out impurities carried in the refrigerant, so as to ensure that the capillary tube is not dirty and blocked.
The refrigerating system provided by the utility model can be applied to a refrigerator, so that the refrigerator has a humidity adjusting function, and the humidity of a refrigerating chamber can be adjusted while the refrigerating temperature is ensured.
The utility model also provides a control method of the refrigerator refrigeration system with the humidity adjusting function, and the control method can be used for controlling the refrigerator refrigeration system with the humidity adjusting function. As shown in fig. 2, the control method of the refrigerator cooling system with humidity adjustment function includes the following steps:
step S1: detecting the humidity of the refrigerating chamber, and judging the humidity of the refrigerating chamber and the target humidity;
step S2: when the humidity of the refrigerating chamber is higher than the target humidity, the opening degree of the electronic expansion valve 7 is reduced, the flow leading to the refrigerating evaporator 6 is reduced, the evaporation temperature of the refrigerating evaporator 6 is reduced to be lower than the dew point temperature, the moisture condensation of the air in the chamber is accelerated, and the dehumidification is realized;
step S3: when the humidity of the refrigerating chamber is lower than the target humidity, the opening degree of the electronic expansion valve 7 is increased, the flow leading to the refrigerating evaporator 6 is increased, the evaporating temperature of the refrigerating evaporator 6 is increased to be higher than the dew point temperature, the water loss of the chamber is reduced, and humidity control is achieved.
Wherein the dew point temperature may be calculated from the target temperature and the target humidity.
The control of temperature is ensured while adjusting humidity by adjusting the opening degree of the electronic expansion valve 7 in the refrigeration system. The temperature control of the refrigerating chamber requires a certain temperature difference between the evaporating temperature of the refrigerating evaporator and the temperature of the refrigerating chamber. For more precise control of the temperature and humidity of the refrigerating compartment, it is preferable that, before step S1, a step of gradually adjusting the opening degree of the electronic expansion valve 7 and recording the corresponding refrigerating evaporator evaporation temperature so as to establish a mapping relationship between the refrigerating evaporator evaporation temperature and the opening degree of the electronic expansion valve 7 is further included. When the humidity of the refrigerating chamber is greater than the target humidity and the difference value between the temperature of the refrigerating chamber and the target temperature is smaller than a first preset temperature difference value, the temperature of the refrigerating chamber is closer to the target temperature, and the opening degree of the expansion valve is adjusted according to the mapping relation between the evaporating temperature of the refrigerating evaporator and the opening degree of the electronic expansion valve 7, so that the evaporating temperature of the refrigerating evaporator is reduced, the difference value between the evaporating temperature of the refrigerating evaporator and the temperature of the refrigerating chamber is not greater than a second preset temperature difference value, and the overlarge difference value between the evaporating temperature of the refrigerating evaporator and the temperature of the refrigerating chamber is avoided. When the humidity of the refrigerating chamber is smaller than the target humidity and the difference value between the temperature of the refrigerating chamber and the target temperature is smaller than a first preset temperature difference value, the temperature of the refrigerating chamber is closer to the target temperature, and the opening degree of the expansion valve is adjusted according to the mapping relation between the evaporating temperature of the refrigerating evaporator and the opening degree of the electronic expansion valve 7, so that the evaporating temperature of the refrigerating evaporator is increased, and the difference value between the evaporating temperature of the refrigerating evaporator and the temperature of the refrigerating chamber is not larger than a second preset temperature difference value. Wherein the first preset temperature difference value can be set to 1-3 ℃, such as 1 ℃, 2 ℃, 3 ℃ and the like, preferably the first preset temperature difference value can be set to 2 ℃; the second predetermined temperature difference may be set to 15 ℃ to 20 ℃, such as 15 ℃, 20 ℃, etc., preferably the second predetermined temperature difference may be set to 20 ℃.
Finally, it should be noted that: the above embodiments and examples are only used to illustrate the technical solutions of the present invention, and are not limited thereto; although the present invention has been described in detail with reference to the foregoing embodiments and examples, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments or examples may still be modified, or some of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments or examples of the present invention.
