The utility model carry out secondary refrigeration principle be；Evaporator carries out Cooling capacity exchanging with refrigerating medium, passes through cooling pump
Refrigerating medium is transported between freezer and carries out refrigeration cool-down, refrigerating medium under normal pressure between freezer and secondary refrigeration system circulate,
Refrigerating medium cycle of higher pressure mode effectively reduces equipment and personnel's maintenance cost between more traditional freezer, while improving the peace of freezer
Quan Xing；Compressor connects heat exchanger, the heat for collecting compressor, and heat is stored in warm fluid defrosting tank, right
When being defrosted between freezer, refrigerating medium in freezer is all transported in refrigerating medium surge tank, warm fluid medium is then passed through into warm fluid
Pump is defrosted between being transported to freezer, effectively saves energy consumption；When carrying out plant maintenance, maintenance between freezer, changing, by refrigerating medium
All deliver in refrigerating medium surge tank and store, solve the problem of system maintenance is difficult.In addition, can be by this when night, the charge for electricity is small
Utility model oepration at full load, makes cold be stored in refrigerating medium, when daytime, power consumption was big, can close system of the present utility model
Cold group (evaporator, expansion valve, compressor, condenser, cooling system are referred to as refrigeration unit) allows the cold of storage to be followed
Ring, can be achieved the peak load shifting of electric power.
The beneficial effects of the utility model are：The utility model can effectively solve the peace that existing cold storage refrigerating system is present
Full sex chromosome mosaicism, meanwhile, the utility model carries out freezer defrosting using waste heat, saves energy consumption, also stores cold using refrigerating medium,
Peak load shifting, avoids peak of power consumption.

Embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings, described is to this practicality
New explanation rather than restriction.
Fig. 1 provides a kind of economical cold storage refrigeration system of energy-saving safe, including warm fluid defrosting tank 8, heat exchanger 7, steaming
Send out device 8, refrigerating medium surge tank 9, condenser 5, expansion valve 4, compressor 1 and cooling system 6, the warm fluid defrosting connection of tank 8 institute
State heat exchanger 7, the evaporator 2 connects the refrigerating medium surge tank 9, the heat exchanger 7 successively with the condenser 5,
The expansion valve 4, the evaporator 2 and the formation refrigeration cycle of the compressor 1；The cooling system 6 and the condensation
Device 5 is connected, and the cooling medium of the cooling system is water；The warm fluid defrosting tank 8 and the refrigerating medium surge tank 9 pass through respectively
9 connection between warm fluid pump 11 and cooling pump 10 and freezer.
The medium that the refrigerant of the present embodiment is selected in liquefied ammonia, warm fluid defrosting tank and refrigerating medium surge tank is from commercially available stainless
Lose metal, nontoxic, non-flammable refrigerating medium.Make after cold, evaporator 2 passes to cold in refrigerating medium surge tank 3
Refrigerating medium, refrigerating medium realizes between freezer 9 and the interior circulation of refrigerating medium surge tank 3 by cooling pump 10, cold is delivered to cold
But 9 between, to realize the purpose of cooling, wherein the volume of refrigerating medium surge tank 3 is 1.5 times of refrigerating medium total amount.In the present embodiment
