Description
Technical field
The present invention relates to freezer technical field, in particular to a kind of freezer circulation with high and low temperature refrigeration handoff functionality
System.
Background technique
Freezer is widely applied in modern agricultural and sideline product and food production, is divided at present according to the difference of repertory
High temperature cold storage and low-temperature cold-storage, wherein high temperature cold storage is mainly used for storing fresh fruit, egg product and Chinese medicine etc., low temperature
For storing frozen good food, existing high/low temperature dual temperature freezer mostly uses greatly two sets of refrigeration compressors, works as storage freezer
When the article of room needs to refrigerate, cryogenic refrigeration compressor set is closed, starts high-temperature refrigeration compressor set, temperature is relatively high
Cooling air is sent into storeroom；When the article of storeroom needs to freeze, high-temperature refrigeration compressor set is closed, starts cryogenic refrigeration
The relatively low cooling air of temperature is sent into storeroom by compressor set, and high and low temperature switching is cumbersome, increases freezer power consumption.
Summary of the invention
In order to overcome defect present in background technique, the present invention provides a kind of with high and low temperature refrigeration handoff functionality
The freezer circulatory system.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of to refrigerate handoff functionality with high and low temperature
The freezer circulatory system, including compressor and the condenser being connected with compressor, it is characterised in that: the condenser and gas-liquid separation
The inlet of device connects, and the liquid outlet of the gas-liquid separator is connect with solenoid valve, the solenoid valve respectively with refrigerating evaporator
It is connected with refrigeration evaporator, the refrigerating evaporator and refrigeration evaporator are connect with fluid reservoir, the fluid reservoir and the compression
Machine connection, the gas outlet of the gas-liquid separator and the air inlet of condenser/evaporator connect, and the first of the condenser/evaporator goes out
Liquid mouth is connect through first throttle valve with refrigerating evaporator, and the second liquid outlet of the condenser/evaporator is through second throttle and liquid storage
Tank connection.
In the above scheme, the solenoid valve is two-position three way magnetic valve.
In the above scheme, the condenser is horizontal condenser.
Compared with prior art, the beneficial effects of the present invention are: using two-position three way magnetic valve, the opening when needing to refrigerate
Refrigeration evaporator closes refrigerating evaporator, and compressor refrigeration, freezer are in the state in high temperature library at this time；When needing to freeze, beat
Refrigerating evaporator is opened, refrigeration evaporator is closed.Compressor refrigeration at this time, freezer are in the state of Freezing room, pass through two-position three way
The switching in high and low temperature library is realized in the switching of solenoid valve state, simple, convenient, while avoiding the repeated priming of compressor
And increase freezer power consumption.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
In figure: 1- compressor；2- condenser；3- gas-liquid separator；4- solenoid valve；5- refrigerating evaporator；6- refrigeration evaporation
Device；7- fluid reservoir；8- condenser/evaporator；901- first throttle valve；902- second throttle.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of freezer circulatory system with high and low temperature handoff functionality provided by the invention, including compression
Machine 1 and the condenser 2 being connected with compressor 1, condenser 2 are connect with the inlet of gas-liquid separator 3, and gas-liquid separator 3 goes out
Liquid mouth is connect with solenoid valve 4, and solenoid valve 4 is connect with refrigerating evaporator 5 and refrigeration evaporator 6 respectively, refrigerating evaporator 5 and refrigeration
Evaporator 6 is connect with fluid reservoir 7, and fluid reservoir 7 is connect with compressor 1, gas outlet and the condenser/evaporator 8 of gas-liquid separator 3
Air inlet connection, the first liquid outlet of condenser/evaporator 8 are connect through first throttle valve 901 with refrigerating evaporator 5, condenser/evaporator
8 the second liquid outlet is connect through second throttle 902 with fluid reservoir 7.
Wherein, solenoid valve 4 is two-position three way magnetic valve.
Wherein, condenser 2 is horizontal condenser.
The operation principle of the present invention is that: when the article of storeroom needs to refrigerate, first throttle valve 901 is closed, opens the
Then two throttle valves 902 open refrigeration evaporator 5 by two-position three way magnetic valve 4, close refrigerating evaporator 6, at this time compressor
Refrigeration, freezer are in high temperature library state；When the article of storeroom needs to freeze, first throttle valve 901 is opened, closes the second section
Valve 902 is flowed, refrigerating evaporator 6 is then opened by two-position three way magnetic valve 4, closes refrigeration evaporator 5, at this time compression mechanism
Cold, freezer is in Freezing room state.
The above is only embodiments of the present invention, are not intended to limit the scope of the invention, all to utilize the present invention
