Description

A kind of high-low pressure cool-heat-exchanger
Technical field
Freezer equipment field is the utility model is related to, specifically a kind of high-low pressure cool-heat-exchanger.
Background technology
Cold storage refrigerating system includes the parts such as compressor, condenser, throttle valve and the evaporator that is arranged in freezer, existing letter Singly introduce its refrigeration principle:As shown in Figure 1, the low-temp low-pressure gaseous refrigerant come out from evaporator enters the suction of compressor Tracheae, by the compression of compressor, original low-temp low-pressure gaseous refrigerant is changed into high temperature and high pressure gaseous refrigerant from pressure The exhaust pipe of contracting machine is discharged and sent to condenser, within the condenser refrigerant transfer heat to surrounding air or water and condense Into liquid, what is finally come out from condenser is medium temperature high pressure liquid refrigerant, carries out decompression processing into throttle valve afterwards, is depressured Refrigerant afterwards subsequently enters in evaporator and absorbs cooled medium(Water or air in freezer)Heat and vaporize change For the gaseous state of low-temp low-pressure, the gaseous refrigerant of subsequent low-temp low-pressure is again introduced into the air intake duct of compressor so as to carry out circulation system It is cold.
In order to improve the refrigeration effect of cold storage refrigerating system, it would be desirable to allow and come out and enter in evaporator from throttle valve Refrigerant temperature is more low better, only in this way could absorb more heats from freezer inner periphery air or water so as to play into one Step reduces the effect of cold storehouse temperature, it is therefore desirable to extends compressor operating time, process energy consumption is big, especially for large-scale Freezer, its operating cost are especially high;Compressor works long hours at the same time, substantially reduces its service life, and compressor is as system The core component of cooling system, manufacture and maintenance cost are all very high.
Utility model content
In order to overcome above-mentioned technical disadvantages, the utility model provides a kind of high-low pressure cool-heat-exchanger, exchanger connection Between the condenser and compressor of cold storage refrigerating system, thus without additionally allow by way of compressor continuous service so as to The temperature further reduced in freezer is played, but by the double evaporation-cooling of refrigerant so as to be lowered into the condensation in throttle valve So as to be lowered into the physics mode of the temperature of condensing agent in evaporator indirectly, which does not have to expend and appoints the temperature of agent What electric energy just can play further refrigeration effect, greatly reduce the refrigeration cost of freezer;Greatly reduce compressor at the same time The duration of runs, directly extends the working life of compressor.
To reach above-mentioned purpose, the technical scheme adopted by the utility model is that:Set respectively including tank body, above tank body into Tracheae I, air outlet pipe I, air inlet pipe II and air outlet pipe II, the air inlet connection cold storage refrigerating system evaporator of the air inlet pipe I Air outlet pipe connects the vertical siphunculus being arranged in tank body, the gas outlet connection freezer refrigerating system of the air outlet pipe I with its gas outlet The air intake duct of system compressor, the liquid outlet of the air inlet connection cold storage refrigerating system condenser of the air inlet pipe II and its gas outlet Connection is arranged on the import of the condenser pipe in tank body, and the outlet of the condenser pipe connects cold storage refrigerating system section by air outlet pipe II Flow the inlet of valve.
Operation principle is as follows:
The set cool-heat-exchanger will originally be evaporated equivalent to the auxiliary system of a cold storage refrigerating system from cold storage refrigerating system The gas-liquid mixed refrigerant that the air outlet pipe of device comes out no longer flows directly into the air intake duct of cold storage refrigerating system compressor, but first flows To the air inlet of the air inlet pipe I of this cool-heat-exchanger, flowed into afterwards by vertical siphunculus in tank body, the process is equivalent to condensing agent From an aperture, less pipeline flows into the very big pipeline in an aperture, also corresponds to suppress and is mixed in the higher gas-liquid of the pressure of small space Condensing agent is closed once to flow in the very big container in space, at this time in tank body the pressure of condensing agent than small in vertical siphunculus It is more, further reduced with pressure reduction condensing agent temperature, at the same time, originally will go out liquid from cold storage refrigerating system condenser The medium temperature high-pressure refrigerant of mouth out no longer flows directly into the throttle valve of cold storage refrigerating system, but first flows to this cool-heat-exchanger Air inlet pipe II and flow into the condenser pipe in tank body, be the refrigerant liquid of medium temperature high pressure in condenser pipe at this time, and from vertical logical In pipe inflow tank body is the refrigerant of low-temp low-pressure, therefore the refrigerant particle of low-temp low-pressure will surround condenser pipe and to cold Refrigerant in solidifying pipe carries out cooling processing, after cooling, the refrigerant in refrigerant suction condenser pipe in tank body Heat vaporizes the air intake duct for being changed into gaseous state and flowing into cold storage refrigerating system compressor again, and the temperature of the refrigerant in condenser pipe Further reduce and flow to the inlet of cold storage refrigerating system throttle valve;
Stress herein:
For the cold storage refrigerating system without the cool-heat-exchanger, original throttle valve that flows into is medium temperature high-pressure refrigeration Agent, we have been described above inside the background technology of the application, and original refrigeration system is in order to further reduce in freezer Temperature, it is necessary to which the working time of extra raisings compressor could allow the temperature of the refrigerant out of throttle valve inflow evaporator It is lower, and the cold storage refrigerating system with this cool-heat-exchanger is directly the refrigerant for providing low temperature of throttle valve, therefore evaporate Device directly obtains the relatively low refrigerant of temperature, so as to further reduce the air or water of surrounding by temperature relatively low refrigerant Temperature, so as to play the effect for reducing cold storehouse temperature, the purely physical process of the process, any electricity need not be expended by further freezing Can, allow freezer to use more energy conservation and environmental protection;No longer further cooled down by way of extending compressor operating time at the same time, The duration of runs of compressor is substantially reduced, effectively extends the service life of compressor.
The utility model devises, and the tank body upper seal connects a upper cover, set respectively on upper lid air inlet pipe I, Air outlet pipe I, air inlet pipe II and air outlet pipe II, the vertical siphunculus are located at tank body cavity sidepiece and are open below close to tank body tank Bottom, the condenser pipe are located at middle part or middle and upper part in tank body cavity.
The utility model devises, and connects a spout in vertical siphunculus lower part, and the opening direction of the spout is towards tank body Interior condenser pipe.
The utility model devises, and the condenser pipe is continuous U-shaped coil pipe or round coil.
