Description
Technical field
The utility model relates to a kind of refrigerator refrigeration systems based on PCM phase-change heat-exchange double-condenser, belong to refrigerator, refrigerator-freezer
Equal refrigerating fields.
Background technique
In summer operation, the heat that condenser distributes has been exhausted directly in indoor environment traditional domestic refrigerator, thus
The energy consumption for increasing compressor reduces the COP of refrigerator.In response to this problem, the utility model devises a kind of based on PCM
The refrigerator refrigeration system of phase-change heat-exchange double-condenser, this is the condenser and traditional fiber tube wrapped up by phase-change material
The domestic refrigerator that formula condenser is together in parallel makes refrigerant walk different circuits, to flow through different by the switching of valve
Condenser.In one day, environment temperature night be it is minimum, noon is highest.During environment temperature peak value, refrigerant is
Flow through the condenser wrapped up by phase-change material.Requirement to phase-change material is that its fusion temperature will be lower than external peak environment
Temperature, phase-change material is constantly from 7PCM condenser draw heat, to be gradated by solid-state as liquid, storage 7PCM condenser
Heat, the energy consumption of compressor can be thus reduced, to increase the COP of refrigerator.
After phase-change material is changed into liquid from solid, refrigerant is set to begin to flow through traditional threaded pipe type by switch valve
Condenser.When night, ambient temperature is lower than phase-change material fusion temperature, and phase-change material becomes solid from liquid again
Body circuits sequentially.
Utility model content
The main component of general domestic refrigerator includes: compressor 1, condenser 8, capillary 9, evaporator 10, these portions
Part is connected by refrigerant tubing.The purpose of this utility model is that: be mounted in original refrigerator refrigeration system solenoid valve,
PCM condenser 7.
To achieve the above object, the technical solution adopted in the utility model is a kind of based on PCM phase-change heat-exchange double-condenser
Refrigerator refrigeration system, the refrigerator refrigeration system include compressor 1, solenoid valve a2, solenoid valve b3, solenoid valve c4, solenoid valve d5,
Phase-change material 6, PCM condenser 7, condenser 8, capillary 9 and evaporator 10；Compressor 1, condenser 8, capillary 9 and evaporation
Device 10 is sequentially connected with composition domestic refrigerator refrigeration structure by refrigerant tubing；Solenoid valve b3 is arranged in compressor 1 and condenser 8
Between pipeline on, solenoid valve c4 is arranged on the pipeline between condenser 8 and capillary 9；8 phase of PCM condenser 7 and condenser
It connects, phase-change material 6 is filled in PCM condenser 7, PCM condenser 7 is connect by solenoid valve a2 with compressor 1, condenser 8
It is connect by solenoid valve d5 with capillary 9.
Compared with prior art, the utility model can be according to the variation of external environment come switching solenoid valve, to make
Refrigerant walks different circuits, flows through different condensers.
Detailed description of the invention
Fig. 1 is the structure connection diagram of the utility model.
In figure: 1, compressor, 2, solenoid valve a, 3, solenoid valve b, 4, solenoid valve c, 5, solenoid valve d, 6, phase-change material, 7,
PCM condenser, 8, condenser, 9, capillary, 10, evaporator.
Specific embodiment
As shown in Figure 1, a kind of refrigerator refrigeration system based on PCM phase-change heat-exchange double-condenser, the refrigerator refrigeration system packet
Include compressor 1, solenoid valve a2, solenoid valve b3, solenoid valve c4, solenoid valve d5, phase-change material 6, PCM condenser 7, condenser 8, hair
Tubule 9 and evaporator 10；Compressor 1, condenser 8, capillary 9 and evaporator 10 are sequentially connected with group by refrigerant tubing and get married
With refrigeration for refrigerator structure；Solenoid valve b3 is arranged on the pipeline between compressor 1 and condenser 8, and solenoid valve c4 setting is condensing
On pipeline between device 8 and capillary 9；PCM condenser 7 is connected with condenser 8, and phase-change material is filled in PCM condenser 7
6, PCM condensers 7 are connect by solenoid valve a2 with compressor 1, and condenser 8 is connect by solenoid valve d5 with capillary 9.
Working method: during environment temperature peak value, solenoid valve a2 and solenoid valve d5 are opened, solenoid valve b3 and solenoid valve c4
It closes, refrigerant flows through PCM condenser 7 at this time, and the melting temperature of selected phase-change material is lower than environment temperature peak value, phase-change material
6 constantly from 7 draw heat of PCM condenser, to be gradated by solid-state as liquid, stores the heat of PCM condenser 7, thus
The energy consumption that compressor can be reduced increases the COP of refrigerator.The circulating path of refrigerant is compressor 1, solenoid valve a2, PCM
Condenser 7, solenoid valve d5, capillary 9 and evaporator 10.
After phase-change material becomes liquid from solid-state, switch valve is closed solenoid valve a2 and solenoid valve d5, solenoid valve b3
It is opened with solenoid valve c4, refrigerant flows through traditional threaded pipe type condenser 8, when night, ambient temperature at this time
Lower than phase-change material fusion temperature, phase-change material changes from liquid into solid again, and the circulating path of refrigerant is compressor 1, electromagnetism
Valve b3, condenser 8, solenoid valve c4, capillary 9 and evaporator 10, circuit sequentially.
