The specific embodiment
as shown in Figure 1, the utility model is achieved like this, the exhaust outlet connecting integration of screw compressor 1 shell and tube condenser 4 in parallel, integrated shell and tube condenser in parallel 4 connects stop valve 5, stop valve 5 connects device for drying and filtering 6, device for drying and filtering 6 connects visor 7, visor 7 connects major loop magnetic valve 8, major loop magnetic valve 8 connects heating power expansion valve 11 and bypass solenoid valve 9 in parallel, heating power expansion valve 11 connects dry evaporator 10, dry evaporator 10 connecting screw rod formula compressor 1 air entries, bypass solenoid valve 9 connects high temperature expansion valve 2, high temperature expansion valve 2 connecting screw rod formula compressor 1 mouth sprays form the loop.In addition, connect cooling water flow adjustable valve 3 between integrated shell and tube condenser in parallel 4 cooling water import and exports.
When 1) unit was opened, stop valve, major loop magnetic valve were opened, and bypass solenoid valve is closed.Cold-producing medium is compressed into high temperature and high pressure gas in screw compressor, enter integrated shell and tube condenser in parallel with thermal release to hot water and cooling water, the cooling water flow adjustable valve is regulated aperture according to hot water effluent's temperature and recuperation of heat amount, completes 100% of compressor heat exhaust and reclaims or the part recuperation of heat; Then pass through stop valve, device for drying and filtering, visor, major loop magnetic valve, after the heating power expansion valve reducing pressure by regulating flow, (chilled water that is cooled is delivered to each end to heat of vaporization in dry evaporator in the absorption chilled water, satisfy user's needs), cold-producing medium becomes low-temp low-pressure gas and returns to screw compressor.
2) in running, during greater than 80 ℃, open bypass solenoid valve when compressor exhaust temperature, refrigerant liquid is injected in helical-lobe compressor through bypass solenoid valve and high temperature expansion valve, thereby reduces compressor exhaust temperature; When compressor exhaust temperature is down to below 70 ℃, close bypass solenoid valve.
