Abstract
The utility model discloses a distributed energy source and ground source heat pump coupled system. A gas engine is capable of burning natural gas to drive a generator. The generator is capable of generating electricity to drive a sewage source heat pump to produce partial heat, the gas engine is capable of burning the natural gas to drive the generator, and the generator is capable of generating the electricity to drive the sewage source heat pump the produce the partial heat, and meanwhile, smoke which is produced by the gas engine enters into an absorption heat pump. Heat in the smoke which is discharged by the gas engine is absorbed by the absorption heat pump. Heat is directly supplied for buildings through heat supply pipelines. After the heat is supplied by the absorption pump, smoke off gas which is discharged out enters into a condensation exchanger, thus other partial heat is recycled. In the waste heat recycling process, waste heat which is discharged by the condensation exchanger is 10% of heat which is produced by combustion of all natural gas. According to the distributed energy source and ground source heat pump coupled system, the partial heat is placed in medium water of a ground source heat pump system through a steam-water heat exchanger, and 9% of the waste heat can be recycled, and the temperature of the medium water can be raised 2 DEG C, and meanwhile, efficiency of a heat pump can be raised about 6% again by the rise of the temperature of the medium water.
Description
Technical field
The utility model relates to distributed energy and pump coupled heat system, especially a kind of distributed energy and soil source heat pump coupled system.
Background technology
Be accompanied by the increase of electricity needs and the aggravation of world energy sources crisis, readjust the energy structure, improve energy utilization rate, improve energy security, the solution environmental pollution is own through becoming the emphasis of China's energy strategy.Distributed energy resource system is a kind of multiple-supplying supply system that is based upon on the cascaded utilization of energy ideal basis, by at Demand-side according to the different demands of user to the energy, realize the energy supply pattern of " temperature counterpart, cascade utilization ", the loss of conveying process is down to minimum, thereby realize the maximization of efficiency of energy utilization and environmental benefit.The Distribution of Natural formula energy is to utilize natural gas to be fuel, and after the combustion machine generated electricity by gas-firing, the high-temperature flue gas of generation was sent into waste heat utilization equipment, can be used for heating winter, can be used for cooling summer, but productive life hot water also, and driving the shortage of heat part can be supplied by the combustion gas of afterburning.Thereby realize the cascade utilization to the energy, can improve efficiency of energy utilization to 80%-90%.That but this conventional distributed energy resource system exists is single, energy utilization rate promotes the problems such as limited, economic not good enough.Therefore produced gradually new distributed energy coupled system, it is based on conventional distributed energy technology be coupled environment, regenerative resource, conventional energy resource system, novel regional complex ENERGY PLANNING, intelligent grid and intelligence communication control technology etc., consisted of a kind of new distribution type energy resource system, but still the situation that exists a part directly to discharge with the flue gas waste gas of low-grade energy.Pollute environment, wasted energy.
Summary of the invention
The utility model is the coupling of distributed energy and soil source heat pump system, solved after the waste heat recovery still the energy waste problem that the direct discharging with the flue gas waste gas of heat causes, and improved the efficient of using energy source.
The utility model is to overcome the technical scheme that its technical problem adopts to be, a kind of distributed energy and soil source heat pump coupled system, comprise distributed energy subsystem, soil source heat pump subsystem, wherein the distributed energy subsystem comprises: gas engine, generator, condensing heat exchanger, absorption heat pump; The soil source heat pump subsystem comprises: soil source heat pump, vapor-water heat exchanger, soil source intermediary waterpipe, water return pipeline, heat supply pipeline, exhaust emission pipe; The gas engine gas-firing drives generator, and the generator generating is as the power supply that drives soil source heat pump; The flue gas of gas engine generation simultaneously enters into absorption heat pump, and the heat that absorption heat pump is prepared directly is space heating by heat supply pipeline; The flue tail gas that absorption heat pump gives off enters into condensing heat exchanger; The flue gas of discharging after the condensing heat exchanger heat exchange enters into vapor-water heat exchanger, and vapor-water heat exchanger is replaced the heat in flue gas in soil heat exchange intermediary's water later, and the waste gas that vapor-water heat exchanger is discharged is discharged by exhaust emission pipe.
Usually the sewage source heat pump system of northern China, the too low intermediary's water temperature that causes of the soil moisture in winter is too low, causes the soil source heat pump can not normal boot-strap.And in said system, condensing heat exchanger gives off all natural gas firing that fume afterheat accounts for and produces 10% of heat, the utility model is replaced this part heat in intermediary's water of soil source heat pump system by vapor-water heat exchanger, can reclaim at least 9% waste heat, can make the temperature of intermediary's water improve 2 ℃, the raising of intermediary's water water temperature simultaneously can improve heat pump efficiency 6% left and right again.
Coupling by distributed energy and soil source heat pump, realize that the system capacity step takes full advantage of, according to the performance of heat pump (Energy Efficiency Ratio be 4.0 consider), 40% electric power that gas engine sends can produce heat or the cold more than 160%, more than 40%, the final primary energy comprehensive utilization ratio of the coupled system of afterheat recovery type distributed energy and soil source heat pump can reach more than 200% in conjunction with the primary energy comprehensive utilization ratio of residual neat recovering system.Native system can also make the electric energy of online difficulty be fully used, and heats by soil source heat pump, and the benefit of the Distribution of Natural formula energy is further promoted, and promotes the benign development of industry.
The beneficial effects of the utility model are: native system realized the taking full advantage of of NG Distributed Energy System fume afterheat, and improved the evaporator end water inlet water temperature of soil source heat pump subsystem, improved entire system efficient.
