Drying room blower fan, outdoor fan are run simultaneously, and freezer wind turbine is not run；The delivery outlet of compressor is defeated by high-pressure working medium gas at this time
Enter into oil eliminator, after lubricating oil separation is come out, high-pressure working medium gas enters in drying chamber heat exchanger, passes through drying room blower fan
Effect, thermal energy is disseminated to the inside in drying library by drying chamber heat exchanger, and working medium after heat exchange is first logical along four-way valve
Connector enter third pass joint so that flow through freezer heat exchanger, expansion valve, liquid storage device, after enter in outdoor heat exchanger,
Under the action of outdoor fan, the working medium in outdoor heat exchanger absorbs the thermal energy of outdoor air, and the working medium for absorbing thermal energy later passes through
Second pass joint of four-way valve enter four-way connection, subsequent working medium by be again introduced into after gas-liquid separator suction port of compressor into
Row persistent loop works, it is ensured that drying library carries out the lasting progress of drying operation；
The method of operation is when only freezer being needed to have demand, and the heat of freezer is scattered to outdoor, and four-way valve must not be electric at this time,
Outdoor fan, freezer wind turbine are run simultaneously, and drying room blower fan is not run；The delivery outlet of compressor is defeated by high-pressure working medium gas at this time
Enter into oil eliminator, after lubricating oil separation is come out, high-pressure working medium gas flows through drying chamber heat exchanger, along the first of four-way valve
Pass joint enters the second pass joint and then flows through outdoor heat exchanger, and under the action of outdoor fan, outdoor heat exchanger dissipates thermal energy
It is multicast to that outdoor, working medium enters after flowing through liquid storage device, expansion valve in freezer heat exchanger later, in the effect of freezer wind turbine
Under, the working medium in freezer parallel operation absorbs the thermal energy in freezer, to reduce the temperature of freezer, absorbs the work of thermal energy later
Matter enters four-way connection, subsequent working medium by being again introduced into compressor after gas-liquid separator by the third pass joint of four-way valve
Entrance carries out persistent loop work, it is ensured that freezer carries out the lasting progress of refrigeration operation；
Starting stage baking room and freezer have a demand simultaneously, control system make four-way valve must not electricity, it is drying room blower fan, cold
Library wind turbine to be hidden to run simultaneously, outdoor fan is not run, after drying library has reached the inside drying temperature of setting later, control system
So that four-way valve must not be electric, outdoor fan, freezer wind turbine are run simultaneously, and drying room blower fan is not run；
Starting stage baking room and freezer have a demand simultaneously, control system make four-way valve must not electricity, it is drying room blower fan, cold
Library wind turbine to be hidden to run simultaneously, outdoor fan is not run, after freezer has reached the inside refrigerated storage temperature of setting later, control system
So that four-way valve obtains electric, drying room blower fan, outdoor fan are run simultaneously, and freezer wind turbine is not run.
It only needs to arrange a set of system between freezer and baking room, by control four-way valve energization whether with
And whether the wind turbine of corresponding region works, you can is carried out at the same time refrigeration and drying, or is individually refrigerated or dried, saving is set
Standby cost and operating cost.
Specific embodiments of the present invention are described in detail above, but content is only the preferable implementation of the invention
