[specific embodiment]
The utility model is mainly by compressor 2, heat regenerator 1, condenser 14, electric cabinet 3, expansion valve 13 constitutes with evaporimeter 12, compressor 2 places on the compressor bracket 11, adopt bolt to connect between the two, compressor bracket 11 is welded on the evaporimeter 12, condenser upper bracket 10 is welded on the condenser 14, condenser 14 is welded on the unit underframe 5 with evaporimeter 12, heat regenerator support 9 is welded on heat regenerator 1 bottom, heat regenerator 1 is connected with bolt between the condenser upper bracket 10 by heat regenerator support 9, place on the condenser 14, electric cabinet 3 places on the electric cabinet support 4, adopt bolt to connect between the two, and electric cabinet support 4 is welded on the condenser 14, expansion valve 13 is welded on evaporimeter 12 porch, device for drying and filtering 8, magnetic valve 15 is connected in turn between condenser 14 and the evaporimeter 12 by copper pipe, and ball valve 6 is welded on the outlet copper pipe place of condenser 14.
Each parts of unit connect order successively by the pipeline trend: compressor 2, heat regenerator 1, condenser 14, ball valve 6, device for drying and filtering 8, magnetic valve 15, expansion valve 13, evaporimeter 12 return compressor 2, form a kind of refrigeration cycle.
The utility model is that the method for utilizing both vapor compression is also recycled the heat radiation of unit when obtaining chilled water, with the handpiece Water Chilling Units of the band recuperation of heat that obtains hot water.The high temperature and high pressure gas that ejects from compressor, before entering condenser, be introduced into heat regenerator and do preliminary condensation, to be heated to 50-60 ℃ by the water of heat regenerator, enter condenser again and do last condensation and become high-pressure sub-cooled liquid, the hot water that comes out from heat regenerator is directly supplied with the place of using hot water to need.
Compressor 2 produces the refrigerant gas of HTHP, compressor 2 is under the driving of motor, from evaporimeter 12, suck gaseous refrigerant, and make in the evaporimeter 12 relevant pressure P0 required when keeping the cold-producing medium evaporation, become the gas of HTHP after compressed machine 2 compressions of the gaseous refrigerant that sucks, enter heat regenerator 1 then.Heat regenerator 1 carries out heat exchange, obtain available hot water, when the refrigerant gas of HTHP is flowed through heat regenerator 1 shell-side, carry out heat exchange with the water of the hot device 1 pipe side of flowing through, in with the preliminary condensation of the refrigerant gas of HTHP, can produce the available hot water (50-60 ℃) of high temperature, reach the energy-conserving and environment-protective effect.
