Enter heat exchanger from hot fluid inlet, cooled down in heat exchanger by low-temperature low-pressure refrigerant, water temperature be reduced to 7 DEG C after from hot fluid
Outlet outflow, and expansion evaporation becomes refrigerant vapour from cold fluid outlet outflow after refrigerant heat absorption.
Remaining low-temperature condenser, warm condenser and high-temperature evaporator are the heat transfer process of refrigerant and water, with it is low
Warm evaporator is principle of uniformity.
Cryogenic compressor and high temperature compressor belong to compression device, absorb and are expanded from cryogenic vaporizer and high-temperature evaporator
The refrigerant vapour of evaporation is simultaneously compressed, and is the main power consuming portions of the complete unit, refrigerant is changed into high temperature height after compression
The refrigerant vapour of pressure, generally require higher than environment temperature, arrange to low-temperature condenser and warm condenser and enter heat release.In low temperature cold
Intercycle distilled water is given in the refrigerant heat release of the high temperature of condenser 3, water temperature is increased to 35 DEG C, and heating for the first time is completed, and can be carried
For 35-45 DEG C of hot water, but now hot water temperature is difficult to reach the demand of big Alternative, it is necessary to further be lifted.
Water circulating pump is middle distilled water system water circulating pump, and as intermediate heat transfer medium, pure steaming is used in the circulation
Distilled water, the corrosion of heat exchanging equipment is reduced, the system distilled water disposably adds.And moisturizing and expansion buffer equipment are set, with
Receive and supplement distilled water because the expansion and the change of contraction that temperature change is brought.

The liquid refrigerant of the medium temperature high pressure after supercooling to come in warm condenser by expansion valve throttle orifice throttling after, into
For the vaporific hydraulic pressure refrigerant of low-temp low-pressure, be evaporation endothermic of the refrigerant in cryogenic vaporizer and high-temperature evaporator (i.e.
Refrigeration) create conditions.
In warm condenser, returned from the hot water of the high-temperature high-pressure refrigerant steam that high temperature compressor comes with technical load side
Water is exchanged heat, and heat is discharged into water, heats water, and water temperature can be made to rise to 65-70 DEG C, even more high, and refrigerant sheet
Body, which then cools, is changed into the liquid refrigerant of medium temperature high pressure, flows to choke valve.
I.e.：12 DEG C of water enter cryogenic vaporizer by cooling water inlet, and low-temperature low-pressure refrigerant steam (generally R22) is in low temperature
The heat of outside 12 DEG C of chilled waters is absorbed in evaporator 311 by exchanging heat, chilled water is cooled to 7 DEG C, produces 7 DEG C of chilled waters.
The vaporization of refrigerant itself heat absorption simultaneously is sucked by cryogenic compressor 312, is compressed into the refrigerant vapour of HTHP, and refrigerant steams
Vapour enters low-temperature condenser 313 and condenses heat release, while intercycle distilled water is heated to 35 DEG C from 30 DEG C, condensed medium temperature
High-pressure refrigerant enters the further decompression cooling of low-temperature circuit expansion valve 314, is finally sucked by cryogenic vaporizer 311, back and forth follows
Ring.The final heat extraction of the circulation is present in the form of hot water in 30 DEG C/35 DEG C of water, waits next high temperature circulation.
Low-temperature low-pressure refrigerant steam in high temperature circulation loop enters high-temperature evaporator 321 and absorbs 35 DEG C of water of opposite side
Heat, water temperature are down to 30 DEG C, are compressed after refrigerant vapour heat absorption by high temperature compressor 322, form the refrigeration of HTHP
Agent steam, it is sent into warm condenser 323 and condenses heat release, while the hot water for heating opposite side has been thusly-formed 65 DEG C to 65 DEG C
Hot water, the refrigerant vapour after heat release is again by the further expansion cooling of high-temperature circuit expansion valve 324, into high-temperature evaporator
321 heat absorptions, are and so on circulated.
Whole units' installation forms a complete water chiller-heater unit in metal shell, being equipped with automatically controlled and display system.Should
Unit introduces 35 DEG C of water the evaporator of another heat-pump apparatus, after heat by evaporator equivalent to being absorbed, then is set by this
Standby condenser is released, and produces the water of higher temperature, leaving water temperature is typically up to 65-70 DEG C, and the two integration of equipments are one
Rise, as an equipment.It is exactly on the whole while 7 DEG C of chilled waters can be produced, while 65-70 DEG C of hot water can be produced.Realize
The actual effect of dual-use.
During installation, it is only necessary to adapter mouth access corresponding cold water pipes and hot water pipeline can supply simultaneously chilled water and
Hot water.
As have recorded the result of 7 experiments and the dimensional structure of unit in table 1 below.
The device parameter of table 1 and size
Understand, refrigeration side provides 7 DEG C of chilled waters, and heating side provides 60 DEG C of hot water, refrigerating capacity 500kW -1700kW, heating
