The first cooling circulation loop is sequentially connected with a first circulation water system and a third circulation water system, and the second cooling circulation loop is sequentially connected with a second circulation water system and a third circulation water system. The integrated machine set for cooling the milk can produce chilled water with large temperature difference and output pure water of 2 DEG C, thereby effectively reducing cost of users and occupation space.
Description
Technical field
The present invention relates to a kind of cooling unit, specifically a kind ofly can cool to 2 ℃ for milk being carried out to cooling one unit by the pure water of ordinary temp is disposable.
Background technology
Growing along with milk industry, because the needs of technique, is used for the unit of cooling milk to obtain applying more and more widely on producing.2 ℃ of pure water that need to use the large temperature difference on producing carry out cooling to milk, but conventional handpiece Water Chilling Units or can not produce the cold water of the large temperature difference; Can not produce the pure water of 2 ℃.For milk industry, need 2 ℃ of pure water of the large temperature difference.In order to produce needed water, user has to buy plurality of devices, to meet the needs of production technology.Increased equipment purchasing expense on the one hand, increased on the other hand occupation area of equipment, maintaining is simultaneously got up and is also relatively bothered.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can be by the disposable milk cooling integrated unit that cools to 2 ℃ of the pure water of ordinary temp.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of milk cooling integrated unit, comprise the first refrigeration cycle that the first compressor, the first condenser, the first expansion valve and the first evaporimeter that are communicated with by circulating successively by pipeline form, and the second refrigeration cycle of forming of the second compressor, the second condenser, the second expansion valve and the second evaporimeter that are communicated with by circulating successively by pipeline, described the first refrigeration cycle is connected with the first circulation, the 3rd circulation successively; The second refrigeration cycle is connected with the second circulation, the 3rd circulation successively.
Described the first circulation is comprised of the first water pump, First Heat Exchanger, the first evaporimeter being communicated with that circulate successively by pipeline;
The second circulation is comprised of the second water pump, the second heat exchanger, the second evaporimeter being communicated with that circulate successively by pipeline;
The 3rd circulation is comprised of the first water inlet pipe, the 3rd water pump, First Heat Exchanger, intermediate connection tube, the second heat exchanger, the first outlet pipe being communicated with that circulate successively by pipeline.
Described heat exchanger is plate type heat exchanger.
The present invention can cool to 2 ℃ by the pure water of ordinary temp is disposable, in milk production process, need not purchase two handpiece Water Chilling Units, has reduced expense, and has saved land used space, and maintenance is convenient.
Accompanying drawing explanation
Accompanying drawing 1 is pipeline catenation principle figure of the present invention.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of milk cooling integrated unit, comprise the first refrigeration cycle that the first compressor 11, the first condenser 21, the first expansion valve 31 and the first evaporimeter 41 that are communicated with by circulating successively by pipeline form, and the second refrigeration cycle of forming of the second compressor 12, the second condenser 22, the second expansion valve 32 and the second evaporimeter 42 that are communicated with by circulating successively by pipeline, described the first refrigeration cycle is connected with the first circulation, the 3rd circulation successively; The second refrigeration cycle is connected with the second circulation, the 3rd circulation successively.
The first circulation is comprised of the first water pump 51, First Heat Exchanger 61, the first evaporimeter being communicated with that circulate successively by pipeline, the second circulation is comprised of the second water pump 52, the second heat exchanger 62, the second evaporimeter being communicated with that circulate successively by pipeline, and the 3rd circulation is comprised of the first water inlet pipe 71, the 3rd water pump 53, First Heat Exchanger, intermediate connection tube 72, the second heat exchanger, the first outlet pipe 73 being communicated with that circulate successively by pipeline.The first water inlet pipe is communicated with the high-temperature-hot-water of extraneous user side, finally from the first outlet pipe, exports the low temperature pure water of 2 ℃, for using in milk production process through the 3rd water pump, First Heat Exchanger, intermediate connection tube, the second heat exchanger.
In addition, heat exchanger is plate type heat exchanger, and expansion valve is electric expansion valve or heating power expansion valve or capillary.
Operation principle of the present invention is:
1, the first refrigeration cycle, the high-temperature high-pressure refrigerant steam that the first compressor 11 is discharged enters the first condenser 21, refrigerant vapour is condensed into the refrigerant liquid of middle temperature high pressure and enters the first expansion valve 31 by the first condenser 21, the refrigerant liquid that the refrigerant liquid of middle temperature high pressure is low-temp low-pressure by reducing pressure by regulating flow when the first expansion valve 31 enters the first evaporimeter 41, the refrigerant liquid of low-temp low-pressure becomes the gaseous refrigerant of low-temp low-pressure and returns to the first compressor 11 at the heat of the interior absorption refrigerating medium of the first evaporimeter 41, form a kind of refrigeration cycle and repeat according to this.The high temperature section that this first refrigeration cycle is unit, the first evaporator temperature is higher.
2, the second refrigeration cycle, the high-temperature high-pressure refrigerant steam that the second compressor 12 is discharged enters the second condenser 22, refrigerant vapour is condensed into the refrigerant liquid of middle temperature high pressure and enters the second expansion valve 32 by the second condenser 22, the refrigerant liquid that the refrigerant liquid of middle temperature high pressure is low-temp low-pressure by reducing pressure by regulating flow when the second expansion valve 32 enters the second evaporimeter 42, the refrigerant liquid of low-temp low-pressure becomes the gaseous refrigerant of low-temp low-pressure and returns to the second compressor 12 at the heat of the interior absorption refrigerating medium of the second evaporimeter 42, form a kind of refrigeration cycle and repeat according to this.The low-temperature zone that this second refrigeration cycle is unit; The second evaporator temperature is lower.
3, the first circulation, the first water pump 51 extracts water at low temperature and enters First Heat Exchanger 61 from the first evaporimeter 41, returns the first evaporimeter 41 after heat exchange.
4, the second circulation, the second water pump 52 extracts lower temperature water and enters the second heat exchanger 62 from the second evaporimeter 42, turns back to the second evaporimeter 42 after heat exchange again.
5, the 3rd circulation, the 3rd water pump 53 is sent into First Heat Exchanger 61 by the first water inlet pipe 71 from user side extracting high-temperature hot water, with the water at low temperature in First Heat Exchanger 61 carry out heat exchange become in warm water, by intermediate connection tube 72, enter the second heat exchanger 62 again, carry out heat exchange with the water at low temperature in the second heat exchanger 62 and become water at low temperature, this water at low temperature is delivered to user side by the first outlet pipe 73.
The present invention produces 2 ℃ of pure water of the large temperature difference, can fully meet milk production technology demand.
