Cell panel 18 is positioned at door body 19 upper surface.
When this utility model is positioned at outdoor, solar panel 18 can be utilized continually under fine day sunshine condition
Ground charges for accumulator 15, thus is greatly improved power-off ability to work of the present utility model, extends cold storing and fresh-keeping under outage condition
Time.
Described direct current compressor 8 connects external DC source 21 by direct current incoming line 20.
Described direct current incoming line 20 is provided with the second temperature detect switch (TDS) 22, and the second temperature detect switch (TDS) 22 connects the second temperature controller
23.Described first alternating current incoming line 13 is provided with the first outage detection device 24, and described direct current incoming line 20 is provided with
Two outage detection devices 25；
Described battery connection line 14 is provided with the first temperature detect switch (TDS) 26, first and detects switch 27 and the second detection switch
28, the first outage detection device 24 connects the first detection switch 27, and the second outage detection device 25 connects the second detection switch 28；First
Temperature detect switch (TDS) 26 connects the first temperature controller 29.
Described first temperature controller 29 and the second temperature controller 23 are all located in cold room 2.It is thus possible in the temperature of cold room 2
During less than design temperature, connect the first temperature detect switch (TDS) 26 and the second temperature detect switch (TDS) 22, timely to direct current compressor 8 for accumulator 15
Power supply creates conditions.
Each throttling arrangement is capillary tube or choke valve.
Described first outage detection device 24 preferably employs A.C. contactor, and described first detection switch 27 is preferably described friendship
The normally-closed contact of stream catalyst.After external alternating current power supply 12 disconnects, as the first outage detection device 24 normally-closed contact from
So just switch to closure state.Certainly, alternating current power supply connect after, as the first outage detection device 24 normally-closed contact the most just
Switch to off-state.
Described second outage detection device 25 preferably employs D.C. contactor, and described second detection switch 28 is the most described directly
The normally-closed contact of stream catalyst.After external DC source 21 disconnects, normally-closed contact (the i.e. second power-off inspection of D.C. contactor
Survey device 25) the most just switch to closure state.Certainly, after external DC source 21 is connected, the normally closed of D.C. contactor is touched
Point nature just switches to off-state.
During work, when the first alternating current incoming line 13 connects external alternating current power supply 12, the first detection switch 27 disconnection,
Thus disconnect the connection of accumulator 15 and direct current compressor 8, now AC compressor 4 works, each layer refrigeration of the first vaporizer 7
Coil pipe constantly outside released cold quantity, cold-storage device 3 absorbs a large amount of cold in the process, and accumulator 15 is charged simultaneously.
When external alternating current power supply 12 power-off, the first outage detection device 24 feedback control first detects switch 27 connection；This
Time, if direct current incoming line has connected the external DC sources 21 such as vehicle electronic circuit, then the second outage detection device 25 feedback control
Second detection switch 28 disconnection, now accumulator 15 is off with direct current compressor 8, external DC source drive
Direct current compressor 8 works.Certainly, when the temperature in the second temperature controller 23 detects cold room 2 is less than design temperature scope, meeting
Automatically disconnect the second temperature detect switch (TDS) 22, thus close direct current compressor 8.Temperature in the second temperature controller 23 detects cold room 2
When degree is higher than design temperature scope, meeting turn on automatically the second temperature detect switch (TDS) 22, thus start direct current compressor 8.Direct current compressor 8
During work, each layer refrigeration coil of the second vaporizer 11 constantly outside released cold quantity, cold-storage device 3 absorbs in a large number in the process
Cold.
When external alternating current power supply 12 and external DC source 21 are in off-position, the first outage detection device 24 feeds back
Controlling the first detection switch 27 connection, the second outage detection device 25 feedback control second detects switch 28 connection simultaneously.Now, as
When temperature in really the first temperature controller 29 detects cold room 2 is less than design temperature scope, can automatically disconnect the first temperature detect switch (TDS)
26, thus disconnect the connection of accumulator 15 and direct current compressor 8；After the temperature in cold room 2 is increased to set point, the
One temperature controller 29 turn on automatically the first temperature detect switch (TDS) 26, now accumulator 15 is powered to direct current compressor 8, thus starts direct current pressure
Contracting machine 8.When direct current compressor 8 works, each layer refrigeration coil of the second vaporizer 11 constantly outside released cold quantity, in the process
Cold-storage device 3 absorbs a large amount of cold.
Cold-storage device 3 absorbs a large amount of cold in AC compressor 4 or direct current compressor 8 when working, thus in exchange compression
During machine 4 or direct current compressor 8 are shut down, it is possible to discharge a large amount of cold to cold room 2, thus delayed in cold room 2 temperature
The speed risen, thus extend the interval between twice start of compressor, reduce the number of starts and the start-stop rate of compressor, it is achieved joint
The about effect of electric energy.
Above example is only in order to illustrative not limiting the technical solution of the utility model, although with reference to above-described embodiment pair
This utility model has been described in detail, and it will be understood by those within the art that: still can enter this utility model
