Description
Technical field
The utility model is related to a kind of freezer, specially photovoltaic freezer.
Background technology
At present, solar energy power generating is applied into freezer, the method for main use is：Daytime uses solar power generation
Refrigerating plant work is driven, unnecessary electricity charges to battery.Night is stored in the electricity in battery using daytime
Drive refrigerating plant work or refrigerating plant work is driven using grid power.
1st, electricity is stored using battery, substantial amounts of battery need to be configured, while also to configure high-power inverter and fill
Electric installation, initial investment is relatively costly.Service lifetime of accumulator is limited, and changing battery can cause freezer use cost to increase
Plus.
2nd, powered using night power network, cannot be realized in the remote districts of power shortage power supply.
Utility model content
The utility model provides a kind of photovoltaic freezer, it is not necessary to configure battery, inverter and charging device,
Solve the problems, such as that the investment of photovoltaic freezer prior art and use cost are high, and in power shortage power supply
The limitation that remote districts cannot use.
Photovoltaic freezer, including evaporator, First Heat Exchanger, the second heat exchanger and frequency-changeable compressor；Described
Evaporator and the second heat exchanger are arranged in freezer, and described First Heat Exchanger is arranged in cold-storage device；Described evaporation
Device is connected by the first magnetic valve with the import of frequency-changeable compressor, is connected with the outlet of frequency-changeable compressor by the second magnetic valve；
Described First Heat Exchanger is connected by the 3rd magnetic valve with the import of frequency-changeable compressor, is compressed by the 4th magnetic valve and frequency conversion
The outlet connection of machine；The second described heat exchanger is connected by water circulating pump with cold-storage device.
Storage has hypothermic saline in described cold-storage device.
When freezer needs refrigeration, the first magnetic valve, the second magnetic valve are connected, and the 3rd magnetic valve, the 4th magnetic valve are closed
Close, refrigerant is freezed by evaporator to freezer；When freezer need not freeze, the 3rd magnetic valve, the 4th magnetic valve
Connect, the first magnetic valve, the second closed electromagnetic valve, refrigerant are carried out cold by First Heat Exchanger to the salt solution in cold-storage device
But, cold is stored；When working at night, water circulating pump is opened, and the hypothermic saline in cold-storage device is pumped into the second heat exchanger, is passed through
Heat exchange is lowered the temperature to freezer.
The photovoltaic freezer that the utility model is provided, the method for realizing the operation of photovoltaic freezer night：
Cold-storage is carried out using cold-storage device, daytime cold-storage, evening is by the heat exchange between freezer and cold-storage device come Keep cool
Storehouse temperature.The problem of photovoltaic freezer night operation is can solve, while cheap；Even if in power network not
The area that can be reached can also use photovoltaic freezer, have actively work to promoting rapid test paper precooling, cold storing and fresh-keeping
With.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the utility model is described with reference to the drawings.
As shown in figure 1, photovoltaic freezer, including evaporator 5, First Heat Exchanger 11, the second heat exchanger 10 and change
Frequency compressor 7；The described heat exchanger 10 of evaporator 5 and second is arranged in freezer 6, and described First Heat Exchanger 11 is arranged on
In cold-storage device 8；Described evaporator 5 is connected by the first magnetic valve 1 with the import of frequency-changeable compressor 7, by the second electromagnetism
Valve 2 is connected with the outlet of frequency-changeable compressor 7；Described First Heat Exchanger 11 is entered by the 3rd magnetic valve 3 and frequency-changeable compressor 7
Mouth connection, is connected by the 4th magnetic valve 4 with the outlet of frequency-changeable compressor 7；The second described heat exchanger 10 passes through water circulating pump 9
It is connected with cold-storage device 8.
Storage has hypothermic saline in described cold-storage device 8.
When freezer 6 needs refrigeration, the first magnetic valve 1, the second magnetic valve 2 are connected, the 3rd magnetic valve 3, the 4th electromagnetism
Valve 4 is closed, and refrigerant is freezed by evaporator 5 to freezer 6；When freezer 6 need not freeze, the 3rd magnetic valve 3,
Four magnetic valves 4 are connected, and the first magnetic valve 1, the second magnetic valve 2 are closed, and refrigerant is by First Heat Exchanger 11 in cold-storage device 8
Salt solution cooled down, store cold；When working at night, water circulating pump 9 is opened, and the hypothermic saline in cold-storage device 8 is pumped into
Second heat exchanger 10, is lowered the temperature by heat exchange to freezer 6.
1st, increase the thickness of the library of freezer 6, the transmission of heat inside and outside storehouse is reduced, to reduce thermal loss；2nd, using change
Frequency refrigeration compressor, the dynamic tracking to solar panel peak power output is realized by regulating frequency, is made full use of too
Positive energy cell panel output electric energy；3rd, cold-storage is carried out using cold-storage device 8, daytime the salting liquid in cold-storage device 8 is cooled down,
Night, the hypothermic saline of storage in cold-storage device 8 was pumped into the heat exchanger in freezer 6 by water circulating pump 9, by freezer 6
Temperature in interior heat brings out that Keep cool storehouse 6.
