Description of the drawings:
FIG. 1 is a schematic diagram of a direct-cooling single-system dual-temperature-control refrigeration system according to the present invention.
FIG. 2 is a flow chart of the refrigeration method of the present invention with dual temperature control for direct cooling single system.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The direct cooling type single-system double-temperature control refrigerating system comprises a compressor 1, a condenser 2, a drying filter 3, a capillary tube 4, a freezing evaporator 5 and a refrigerating evaporator 6 which are sequentially connected through pipelines, wherein a compensation heating wire 7 is adhered to the surface of the refrigerating evaporator 6.
The compressor 1 is driven by the motor to convey and compress the steam of the refrigerator, so that the refrigerant performs refrigeration cycle in the system, and the condenser 2 dissipates the heat of the high-pressure and high-temperature refrigerant gas conveyed by the compressor 1 to the outside of the refrigerator, so that the refrigerant gas is liquefied by heat dissipation and is converted into normal-temperature and high-pressure refrigerant liquid. The drying filter 3 absorbs moisture in the refrigeration system, prevents the refrigeration system from being blocked by ice, absorbs oil stains generated by decomposition in the refrigeration system, compresses dust generated by abrasion of the system, and prevents the refrigeration system from being blocked by dirt. The capillary tube 4 maintains a certain pressure difference between the condenser refrigerant and the evaporator refrigerant, and additionally controls the refrigerant flow rate, changes the refrigerant flow rate, and reduces the refrigerant liquid pressure and temperature. The refrigerant liquid after being decompressed from the capillary tube 4 enters the freezing evaporator 5, is evaporated under low pressure and is changed into gas from liquid, and the heat in the box is absorbed by the freezing evaporator 5, thereby achieving the purpose of refrigerating the freezing chamber. The refrigerant passes through the refrigeration evaporator 6 to absorb the heat in the refrigerating box, thereby achieving the purpose of refrigerating the refrigerating chamber. The compensation heating wire 7 detects the temperature in the refrigerator according to the refrigeration sensor, and judges whether the compensation heating wire 7 needs to perform compensation work or not by combining the temperature actually set by a user, so that the independent temperature control of the refrigeration chamber is realized.
In the direct cooling type single-system double-temperature control refrigerating system, the size of the compensating heating wire is approximately 300mmx250mm, and the power of the heating wire is about 8W-20W.
As shown in fig. 2, when the user needs to adjust the temperature, the user firstly presses the unlocking key for 3 seconds to unlock the refrigerator and then adjusts the temperature of the refrigerating chamber, and the intelligent mode is adopted.
Refrigeration temperature range: 1 ℃, 2 ℃, 3 ℃, 4 ℃, 5 ℃, 6 ℃, 7 ℃, 8 ℃, 9 ℃, 10 ℃, 11 ℃ and 12 ℃.
Freezing temperature range: 6 ℃ below zero, 7 ℃ below zero, 8 ℃ below zero, 9 ℃ below zero, 10 ℃ below zero, 11 ℃ below zero and 12 ℃ below zero.
The refrigerating chamber temperature control mainly controls the start and stop of the compressor by a refrigerating system with a direct-cooling single-system double-temperature control mode so as to meet the requirement of the temperature in the refrigerator, the refrigerating chamber temperature is passively refrigerated by the temperature of the refrigerating chamber, and then according to the actual requirement of a customer, the temperature of a sensor in the refrigerator is detected to control the start and stop of the heating wire to compensate so as to control the temperature in the refrigerator, so that the two chambers are controlled by the temperature respectively.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
