Background technique
People are higher and higher to the quality requirements of food, are to guarantee that food quality has efficacious prescriptions in freezer by food storing Formula, the fresh-keeping ice house that performance is high, effect is good are more and more required by market.The development need refrigerant of freezer, but pass There are problems in controlling cryogen, wherein depletion of the ozone layer and greenhouse effects are especially prominent, novel environment-friendly refrigerant in use Research and use need it is further perfect.So selecting to use refrigerating medium as the indirect cooling refrigeration system circulation of progress Refrigeration modes obtained more and more concerns.
Utility model content
The purpose of this utility model is to provide a kind of indirect cooling system with defrosting function of spent glycol as refrigerating medium System experimental bench.
A kind of indirect cooling system experimental bench of band defrosting function, the experimental bench include that refrigerant circulation, refrigerating medium follow Ring, cooling water circulation and cooling water defrosting circulation;
The refrigerant circulation be rolling rotor compressor gas outlet, condensing heat exchanger, high-pressure reservoir, solenoid valve, Expansion valve, evaporating heat exchanger, gas-liquid separator, rolling rotor compressor air inlet are sequentially connected by pipeline;
The cooling water circulation is cooling water pump outlet, shut-off valve one, condensing heat exchanger, shut-off valve six, shut-off valve Two, cooling water tank, cooling water water pump water inlet are sequentially connected by pipeline;
The refrigerating medium circulation is refrigerating medium pump outlet, air-cooler, shut-off valve three, refrigerating medium water tank, refrigerating medium water The mouth of a river is pumped into be sequentially connected by pipeline;
The cooling water defrosting circulation is cooling water tank water outlet, cooling water water pump, shut-off valve four, air-cooler, cut-off Valve five, shut-off valve two, cooling water tank water inlet are sequentially connected by pipeline.
The utility model has following technical effect that
1, pass through control valve, it can realize that the performance study to indirect cooling refrigeration system can remove it again Frost simultaneously carries out frosting and Defrosting Characteristics research to it.
2, it not only can reach the requirement of refrigeration using the refrigeration system of indirect cooling refrigerating medium, but also making for refrigerant can be reduced Dosage, and the equipment that refrigerant flows through, convenient for centralized management, security performance greatly reinforces.
3. for the defrosting for cooling down refrigeration system indirectly, storehouse temperature fluctuation is smaller by the way of cooling water defrosting, and Energy consumption is moderate.
Detailed description of the invention
Fig. 1 is the indirect cooling system experimental bench schematic diagram with defrosting function.
Specific embodiment
System is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein Specific embodiment is only used to explain this system, is not used to limit this system.
Such as Fig. 1, a kind of indirect cooling system experimental bench of band defrosting function, the experimental bench includes refrigerant circulation, carries Refrigerant cycle, cooling water circulation and cooling water defrosting circulation;The refrigerant circulation includes: rolling rotor compressor 1, condensation Heat exchanger 2, high-pressure reservoir 3, solenoid valve 4, expansion valve 5, evaporating heat exchanger 6, gas-liquid separator 7;The cooling water circulation packet It includes: cooling water water pump 8, shut-off valve 1, shut-off valve 2 10, shut-off valve 6 19, condensing heat exchanger 2, cooling water tank 11;It is described Refrigerating medium circulation includes: refrigerating medium water pump 12, air-cooler 13, freezer 14, shut-off valve 3 15, refrigerating medium water tank 16;The cooling Water defrosting circulation includes: cooling water tank 11, cooling water water pump, shut-off valve 2 10, shut-off valve 4 17, shut-off valve 5 18, cold wind Machine 13;
Refrigerant circulation be 1 gas outlet of rolling rotor compressor, condensing heat exchanger 2, high-pressure reservoir 3, solenoid valve 4, Expansion valve 5, evaporating heat exchanger 6, gas-liquid separator 7,1 air inlet of rolling rotor compressor are sequentially connected by pipeline;Overheat Refrigerant gas is compressed by rolling rotor type cold compressor, and the high temperature and high pressure gaseous refrigerant being discharged from compressor is water cooled Board-like condensing heat exchanger condensation, liquid refrigerant enter plate-type evaporator after throttling at throttle valve, evaporation endothermic becomes refrigeration Agent superheated steam, superheated steam are again introduced into compressor and are compressed, and form refrigerant circulation;
Cooling water circulation is 8 water outlet of cooling water water pump, shut-off valve 1, condensing heat exchanger 2, shut-off valve 6 19, shut-off valve 2 10, cooling water tank 11,8 water inlet of cooling water water pump are sequentially connected by pipeline;Shut-off valve 4 17, shut-off valve 5 18 are in Normally off, shut-off valve 6 19 are in normally open.Cooling water provides power by cooling water pump, absorbs refrigerant within the condenser The heat released is condensed, returns in cooling water tank, is radiated by spray equipment.When cooling water tank temperature reaches 30 DEG C, wind Fan starting forms forced convertion and helps cooling water-cooled;
Refrigerating medium circulation is 12 water outlet of refrigerating medium water pump, air-cooler 13, shut-off valve 3 15, refrigerating medium water tank 16, refrigerating 12 water inlet of agent water pump is sequentially connected by pipeline, and refrigerating medium exchanges heat in plate-type evaporator and refrigerant, is stored in refrigerating In the water tank of agent, air-cooler 13 is located in freezer 14, and low temperature refrigerating medium is sent into cooler by coolant pump and is provided to freezer Cooling capacity, then refrigerating medium is again introduced into evaporator and exchanges heat;
Cooling water defrosting circulation is 11 water outlet of cooling water tank, cooling water water pump 8, shut-off valve 4 17, air-cooler 13, cuts Only valve 5 18, shut-off valve 2 10,11 water inlet of cooling water tank are sequentially connected by pipeline.Close shut-off valve 3 15, shut-off valve 6 19, open shut-off valve 4 17, shut-off valve 5 18.Cooling water provides power by cooling water pump, and cooling water is passed through cooler In coil pipe, cooling water tank is returned to after defrosting;
Pass through control valve, it can realize that the performance study to indirect cooling refrigeration system can defrost to it again And frosting and Defrosting Characteristics research are carried out to it.
The above is only the preferred embodiment of this patent, it is noted that for the common skill of the art For art personnel, under the premise of not departing from this system principle, several improvements and modifications can also be made, these improvements and modifications Also it should be regarded as the protection scope of this patent.
