Description

A kind of economical cold storage refrigeration system of energy-saving safe

Technical field

The utility model belongs to technical field of refrigeration equipment, and in particular to a kind of economical refrigeration system of energy-saving safe System.

Background technology

Freezed more than existing cold storage refrigerating system using liquefied ammonia, but the freezer freezed in recent years using liquefied ammonia leaks the peace such as blast Total event emerges in an endless stream, and a series of policy requirements have been put into effect to this country relates to ammonia freezer and rectified and improved, and reforming mode is usually Following two, one is to be changed to freon once to be freezed, and refrigerating efficiency of freon it is low while can also destroy smelly Oxygen layer, causes greenhouse effects;Another reforming mode is to use secondary refrigeration method, i.e., make ammonia or freon refrigerator Cold passes to refrigerating medium, and refrigerating medium, which again transports cold, to be realized between freezer and freeze, but traditional secondary refrigerating method is mostly not Possess defrosting function, and refrigerating efficiency is low, and power consumption is high.

The content of the invention

The problem of existing for prior art, the utility model provides a kind of economical cold storage refrigeration system of energy-saving safe. The technical solution of the utility model is:

A kind of economical cold storage refrigeration system of energy-saving safe, including warm fluid defrosting tank, heat exchanger, evaporator, refrigerating medium Surge tank, condenser, expansion valve and compressor, the warm fluid defrosting tank connect the heat exchanger, and the evaporator connects institute State refrigerating medium surge tank, the heat exchanger successively with the condenser, the expansion valve, the evaporator and the compressor Refrigeration cycle is formed, the warm fluid defrosting tank and the refrigerating medium surge tank pass through warm fluid pump and cooling pump and freezer respectively Connection.

Further, the economical cold storage refrigeration system of the energy-saving safe also include cooling system, the cooling system with The condenser connection, the cooling medium of the cooling system is water.

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.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model, wherein, 1, compressor;2nd, evaporator;3rd, refrigerating medium surge tank;4、 Expansion valve;5th, condenser;6th, cooling system;7th, heat exchanger;8th, warm fluid defrosting tank;9th, between freezer;10th, cooling pump;11st, warm up Liquid pump.

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 In, this is small for the refrigeration cycle that refrigerant is formed in heat exchanger 7, condenser 5, expansion valve 4, evaporator 2 and compressor 1 Scope interior circulation, and refrigerating medium then between freezer 9 a wide range of interior atmospheric circulating, it is ensured that production, operation security.

When carrying out freezer defrosting, the refrigerating medium of between freezer 9 interior operations is all returned in refrigerating medium surge tank 3 and stored, Now comb is sky in freezer, and the defrosting liquid in warm fluid tank 8 is squeezed between freezer into 9 by warm fluid pump and defrosted, after defrosting Warm fluid is returned to be continued to repeat above-mentioned process of refrigerastion after warm fluid tank 8.

The present embodiment partial circulating in close range by refrigerant, refrigerant addition subtracts significantly compared with directly refrigeration It is small, it is easy to replace refrigerant to carry out systemic circulation by refrigerating medium in 9 between management, freezer, it is achieved thereby that refrigerant is operated with freezer Between separation, improve the safety in utilization of whole system.

When night, the charge for electricity is small, refrigeration machine oepration at full load, cold can be stored in refrigerating medium, daytime, power consumption was big When, refrigeration unit can be closed, allows the cold of storage to be circulated, the peak load shifting of electric power is realized.

The present embodiment can effectively improve refrigeration, solve the unsafe present situation of traditional freezer, accomplished saving electric power Cost, personnel cost, realize energy-conservation purpose, operating personnel through simple training can normal operating, simplify refrigerating operation mistake Journey, with good economic benefit and social benefit.
