Further specify below below in conjunction with accompanying drawing the present invention being done:
Shown in accompanying drawing; Refrigeration system and heating are merged into system of waste heat recovering energy conserving Cooling and Heat Source among the present invention; The output that the waste heat recovering energy conserving cold and heat source system comprises cold and hot recovery source pump 1, stainless steel heat tracing water tank 2, stainless steel savings attemperater 3 and waste heat recovery automatic electric control device 9 said cold and hot recovery source pump 1 pipeline respectively connects the input of the terminal air conditioner water circulatory system 11, stainless steel heat tracing water tank 2, stainless steel savings attemperater 3; The output of the said terminal air conditioner water circulatory system 11 connects the input of cold and hot recovery source pump 1 through chilled water circulating pump 5 pipelines; The output of said stainless steel heat tracing water tank 2, stainless steel savings attemperater 3 connects the input of cold and hot recovery source pump 1 through heating water-circulating pump 4 pipelines; The input pipeline of said stainless steel heat tracing water tank 2 connects running water; The output of said stainless steel heat tracing water tank 2 connects the input that stainless steel is saved attemperater 3 through heat accumulation water booster pump 6 pipelines, and the output pipeline of said stainless steel savings attemperater 3 connects domestic hot-water's water system 10.The input pipeline of said stainless steel heat tracing water tank 2 connects hot water backwater system 12.Said stainless steel heat tracing water tank is provided with moisturizing booster pump 13 with the pipeline that is connected between the running water, and said stainless steel savings attemperater 3 is provided with domestic hot-water supply frequency conversion booster pump 7 with the pipeline that is connected between domestic hot-water's water system 10.Said cold and hot recovery source pump 1, stainless steel heat tracing water tank 2, stainless steel savings attemperater 3, heat water-circulating pump 4, chilled water circulating pump 5, heat accumulation water booster pump 6, domestic hot-water supply frequency conversion booster pump 7, moisturizing booster pump 13 respectively circuit connect waste heat recovery automatic electric control device 9.Said waste heat recovery automatic electric control device 9 circuit connect frequency-changing control system device 8.
Operation principle of the present invention is: cold and hot recovery source pump is the two-way energy that obtains from water and in the air; When refrigeration, make hot water to the heat that is discharged into the space, in heat supplying process, from outdoor air, absorb heat through air-cooled evaporimeter through the water-cooled evaporimeter.And the produced cold air of cold and hot recovery source pump, hot gas reached refrigeration, heats the course of work of circulation; Cold air is through the chilled water circulating pump; Domestic hot-water and heating installation are through heating water-circulating pump, stainless steel heat tracing water tank and stainless steel savings attemperater; And waste heat recovery automatic electric control device, frequency-changing control system device can provide indoor required cold air, hot water simultaneously, do not need the complicated external control device of extra increase.
Two hot-water lines one that are connected with cold and hot recovery source pump go out one time; The supply domestic hot-water and winter heating installation; The domestic hot-water adopts converter plant, motor-driven valve, flow switch, check-valves, Pressure gauge, thermometer, filter, Hand-operated butterfly valve, air bleeding valve, by-passing valve, pressure-reducing valve to be heated to about 55 ℃ through the circulation of stainless steel heat tracing water tank and to stainless steel savings attemperater, directly gets into domestic hot-water's water system, and domestic hot-water's return water system then gets into the heating that circulates again of stainless steel heat tracing water tank.Winter heating then air conditioner water is handed over through plate and stainless steel heat tracing water tank circulation heating entering central air-conditioning heating system.
Two cold water pipes one that are connected with cold and hot recovery source pump go out one time; Get into the central air-conditioning refrigeration system through chilled water circulating pump, flow switch, Pressure gauge, check-valves, Hand-operated butterfly valve, differential-pressure bypass valve, air bleeding valve, thermometer etc.; Through frequency conversion fan automatically be distributed to space when not needing cold air winter.
The present invention is a core with technology such as heat pump of recovering residual heat unit, waste heat recovery automatic electric control device, Polyurethane foaming double-layer stainless steel attemperater and frequency-changing control systems; Machine room specially; Need not change original pipeline, need not auxiliary electric heater unit and stand-by boiler; High benefit produces frozen water, heating installation and domestic hot-water more than 55 ℃ (winter-8 ℃); Energy savings and administrative expenses have been accomplished effective reduction environment temperature and cost efficiency significantly, for replacing the advanced energy conserving system of equipment such as boiler, refrigeration unit, cooling tower, heat exchanger.In addition, the present invention need not change inner air-conditioning duct of existing building thing and knot draining internal pipeline, changes into the open-type system to original domestic hot-water's closed system, and adopts aggregate measures such as converter technique to get into high, medium and low hot water zone, the realization hydraulic equalization.
Annual cold air of the present invention and hot water can economic benefits and social benefits be supplied simultaneously, and can accomplish not have cold water the time, hot water can be provided separately; When not having hot water, can cold air be provided separately, be that a cover is just thrown the environmental protection and energy-saving system that cost is low, energy-saving effect is high, payoff period is the shortest.With the power-economizing method of present implementation bigger difference is arranged, every day of the present invention can regular supply cold air, heating installation and domestic hot-water's (8 ℃) more than 55 ℃, and the domestic hot-water in summer can freely supply, and is the alternative system that really can replace boiler.
The present invention is after cold and hot recovery source pump start, and according to the message that cooling signal, heat supply signal provide, system can automatically switch, and accomplishes following pattern: one, cold air only is provided, and single running supplies the usefulness of room conditioning; Two, the cold air ability equals the hot water ability, and cold air and hot water supply are provided simultaneously; Three, the cold air ability is greater than the hot water ability; Four, the cold air ability is less than the hot water ability; Five, the hot water running only is provided, the usefulness of domestic hot-water and heating installation is provided.
The automatic control operation of hot and cold water of the present invention realizes screen management, can be used for directly doing on the man-machine interface start and shuts down function, is set at hot and cold water pattern or single cold air operation simultaneously according to loading demand, also can single hot water running.Can set the cold water operating temperature minimum is 5 ℃, and the hot water operating temperature is up to 60 ℃, meets central air-conditioning changes in temperature and domestic hot-water's usefulness fully.
The present invention does not receive the restriction of above-mentioned embodiment; The above embodiment; Be a kind of of the more preferably specific embodiment; Those skilled in the art all should be the substitute mode of equivalence not deviating from the change done under spirit of the present invention and the principle, modification, substitute, combination, simplifying, and is included within protection scope of the present invention.
