Technical field
The present invention relates to a kind of air conditioner, especially a kind of air conditioner that utilizes gas engine to be used as power source drive compression machine work realization refrigeration or to heat.
Background technology
At present, central air-conditioning mostly is greatly and adopts motor-driven compressor work or adopt fuel combustion to be undertaken realizing air conditioning function after the heat exchange by cold-producing medium.Applied for " gas heat pump type air conditioner " (application number: 02130144 of patent of invention on August 23rd, 2002 in China as Mitsubishi Heavy Ind. Ltd., publication number: 1403765, open day: on March 19th, 2003, look and remove day: on November 17th, 2004).It also is a kind of gas heat pump type air conditioner, mainly comprises: a compression set, and it has a gas engine as drive source, and forms a kind of refrigeration cycle by circulating refrigerant; A bypass line part, it is arranged on around the space that off-premises station is installed, and comes out by branch in the engine cool water system of pipeline conversion equipment and gas engine; Wherein the used heat of discharging from gas engine is collected and is turned back to the engine cooling water, and cold-producing medium is heated by engine cooling water, to strengthen the air heat ability.But its indoor cold-producing medium is to adopt circulation fluorine class cold-producing medium, technological requirement height; And be vulnerable to story height and remote restriction, indoor online quantity is restricted.
Summary of the invention
The fuel gas wind-cooled heat pump cold/hot water air-conditioner that the purpose of this invention is to provide a kind of energy-saving and environmental protection, economical operation.
The technical solution adopted for the present invention to solve the technical problems is: compressor of air conditioner 2 connection that matches with gas engine 1, the cold-producing medium circulation pipe that links with compressor of air conditioner 2 connects four-way change-over valve 3 respectively, the cold-producing medium circulation pipe water receiving heat exchanger 4, expansion valve 6, check valve 7 and the wind heat exchanger 9 that connect four-way change-over valve 3 connect four-way change-over valve 3, and on water-to-water heat exchanger 4 and connect the equipment 5 of not holding.
The present invention also can and connect assisted capillary 8 on check valve 7.Can and not hold between the equipment 5 yet water pump is installed at water-to-water heat exchanger 4.
The present invention mainly is by the kind compressor of air conditioner of giving of the mechanical energy of utilizing gas engine work to produce, provide required low-temperature receiver of user or thermal source through cross valve commutation again, again low-temperature receiver or thermal source are produced the required chilled water of air-conditioning or the hot water supply air-conditioning is not held equipment through water-to-water heat exchanger.Its adopts gas engine to drive and must motor-driven, thereby has following advantage: be not subjected to electric network influencing, and economical operation, cold and hot equilibrium, and energy-saving and environmental protection, cost are relatively low.Indoor cold-producing medium of the present invention is to adopt recirculated water, and technological requirement is relatively low; And be not subjected to story height and remote restriction, indoor online quantity is also unrestricted.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment 1, the present invention is by gas engine 1, compressor of air conditioner 2, four-way change-over valve 3, water-to-water heat exchanger 4, do not hold equipment 5, expansion valve 6, check valve 7 and wind heat exchanger 9 constitute, as its name suggests, described four-way change-over valve 3 is provided with 4 connectivity ports, compressor of air conditioner 2 connection that matches with gas engine 1,2 cold-producing medium circulation pipes that link with compressor of air conditioner 2 connect 2 connectivity ports of four-way change-over valve 3 respectively, connect the cold-producing medium circulation pipe water receiving heat exchanger 4 of one of four-way change-over valve 3 remaining 2 ports, expansion valve 6, another connectivity port that check valve 7 and wind heat exchanger 9 connect four-way change-over valve 3 constitutes refrigerant circulation loop, and on water-to-water heat exchanger 4 by the water pipe closed circuit and connect the equipment 5 of not holding, gas engine 1 comprises gas-firing, the engine of fuel gas such as liquid gas.Consult Fig. 1.
When need freeze, gas engine 1 drives compressor of air conditioner 2 work, make refrigerant gas that cold-producing medium through compressor of air conditioner 2 changes HTHP into through four-way change-over valve 3 heat exchanger 9 of giving a dinner for a visitor from afar, after carrying out heat exchange, wind heat exchanger 9 and air become the cryogenic high pressure refrigerant liquid, connect expansion valve 6 through check valve 7, the cryogenic high pressure refrigerant liquid becomes low-temperature low-pressure refrigerant liquid after expansion valve 6 diffusions, low-temperature low-pressure refrigerant liquid absorbs the heat in the chilled water after water-to-water heat exchanger 4 and chilled water carry out heat exchange, make chilled water become chilled water, for not holding equipment 5 to give indoor refrigeration, in water-to-water heat exchanger 4, become low-temperature low-pressure refrigerant gas after the heat absorption of low-temperature low-pressure refrigerant liquid and return compressor of air conditioner 2 circulation compression work through four-way change-over valve 3.
When need heat, regulate check valve 7, make the cold-producing medium recycled back, be that gas engine 1 drives compressor of air conditioner 2 work, make cold-producing medium produce the refrigerant gas of HTHP through four-way change-over valve 3 water receiving heat exchangers 4 through compressor of air conditioner 2, high-temperature high-pressure refrigerant gas after water-to-water heat exchanger 4 and chilled water carry out heat exchange release heat in chilled water, make chilled water become hot water for not holding equipment 5 to give indoor heating, change the cryogenic high pressure refrigerant liquid after high-temperature high-pressure refrigerant gas heat release turns cold in water-to-water heat exchanger 4 into and become low-temperature low-pressure refrigerant liquid through check valve 7 heat exchanger 9 of giving a dinner for a visitor from afar after expansion valve 6 diffusion, low-temperature low-pressure refrigerant liquid becomes low-temperature low-pressure refrigerant gas and returns compressor of air conditioner 2 circulation compression work after wind heat exchanger 9 and air carry out heat exchange.
In sum, it mainly is to pass to compressor of air conditioner 2 by the mechanical energy of utilizing 1 work of combustion gas (as natural gas) engine to produce, produce required air conditioning water of user or hot water by the loop direction that four-way change-over valve 3 changes cold-producing medium, promptly provide required low-temperature receiver of user or thermal source, again low-temperature receiver or thermal source are produced the required chilled water of air-conditioning or the hot water supply air-conditioning is not held equipment 5 through water-to-water heat exchanger 4 through four-way change-over valve 3.
Embodiment 2, and the present invention can be by on check valve 7 and connect assisted capillary 8, thereby can strengthen the expansion to cold-producing medium.Consult Fig. 1, all the other are with embodiment 1.
Embodiment 3, and the present invention can and not hold between the equipment 5 at water-to-water heat exchanger 4 yet water pump is installed.Thereby make it not be subjected to story height and remote restriction, indoor online quantity is also unrestricted.Consult Fig. 1, all the other are with embodiment 1 or 2.
The present invention also can carry out comprehensive reutilization as conversion device for pipeline is set to the cylinder sleeve and the using waste heat from tail gas of gas engine by waste-heat recovery device is installed, and also solves problems such as air-conditioning defrost and domestic hot-water.
