(Combined Cooling Heating and Power is produced in hot and cold, Electricity Federation, CCHP) be that one is based upon on cascaded utilization of energy conceptual foundation, will freeze, heat the supply system of (comprising for warm supplying hot water) and power generation process integration.Its maximum feature is exactly carry out cascade utilization to the energy of different quality, temperature higher, the heat energy with larger available energy is used to generating, the heat energy that temperature is lower is then used to heat supply or refrigeration.Not only increase the utilization ratio of the energy like this, and decrease the discharge of carbide and pernicious gas, also there is good economic benefit and social benefit.
As far back as 2000, long-rangely to develop cooperatively " hot and cold, cogeneration system " with USDOE, Oak Ridge National Laboratory, University of Maryland, long-range Central Air-Conditioner is carried out " without seam " with the American-European GTG produced combine, larger Central Air-Conditioner joins less generator: combustor GTG tail gas being introduced Central Air-Conditioner.Generator tail gas utilization rate of waste heat is 80% ~ 90%.Less Central Air-Conditioner is equipped with larger generator: a combustor GTG tail gas part being introduced Central Air-Conditioner, a part introduces custom-designed waste heat generator.Generator tail gas utilization rate of waste heat about 40% ~ 80%.Directly use generator tail gas cooling and warming: specialized designs tail gas generator, generator tail gas is all introduced generator.Generator tail gas utilization rate of waste heat is 40% ~ 70%.
Although in power industry, generating set capacity is larger, and efficiency is higher, and per kilowatt investment is lower, and cost of electricity-generating is also lower; But in particular cases many, it is the indispensable important supplement of centrally connected power supply that is produced from small-sized hot and cold, Electricity Federation:
(1) demand that can meet special occasions is produced in small-sized hot and cold, Electricity Federation.Such as, to power supply safety stability requirement high user, as hospital, bank etc.; The comparatively diversified user of energy demand, also needs the supply of heat or cold energy while needing electric power.
(2) small-sized hot and cold, Electricity Federation is produced power supply mode and can be made up the deficiency of bulk power grid in security and stability.Small gas cogeneration of heat and power system is actual is a kind of internet of energy facilities, it by cellular small-sized, carry out being connected to each other of energy supply facility, improve the energy supply reliability in city, under mains breakdown and unexpected storms (such as earthquake, snowstorm, artificial destruction, war) situation, the power supply of responsible consumer can be maintained.
(3) small-sized hot and cold, that Electricity Federation product power supply mode is the energy comprehensive cascade utilization provides possibility.In the centralized power supply system of routine, form of energy is relatively single-.When user not only needs electric power, and need the confession of other form of energy as cold energy and heat energy seasonable, when meeting above-mentioned needs by means of only electric power, be difficult to the comprehensive cascade utilization realizing energy; And power supply mode is produced with features such as its small scale, flexibility are strong in small-sized hot and cold, Electricity Federation, the organic combination circulated by difference can realize the comprehensive cascade utilization of energy while meeting consumers' demand, and overcome cold energy and heat energy cannot the difficulty of long-distance transmissions.
(4) small gas cogeneration of heat and power can more effective resource allocation, stablize, utilize the resource such as natural gas, coal bed gas constantly, reduce the adjustment of combustion gas, reduce the reserve-production ratio decline because gas peak regulation causes, the wasting of resources that underground natural gas storage tank loss etc. are unnecessary, reduces the construction investment of gas ductwork, improves equipment operating efficiency, thus reach and reduce combustion gas and utilize cost, improve the competitiveness of use gas enterprise.
(5) under planned economic system, industry divides with product, and product and the task of energy facilities are single, electric power, heating power, combustion gas are independent separately, and the overlapping investment construction of energy facilities, adds operating cost, reduce efficiency, directly cause the raising of energy cost.Small-sized hot and cold, Electricity Federation is produced and has been broken traditional boundary, heating, hot water, electricity, cold, combustion gas, water resources rational use and environmental pollution improvement are considered as a whole, with minimum fund, resources and environment cost, exchange the highest returns of investment, energy conversion efficiency and energy facilities usefulness for.
(6) not only self-pollution is little for small cogeneration, and the regulation effect of environmental pollution is also very outstanding.Substantially do not have the pollution of sulfur dioxide, carbon monoxide and dust, nitrogen oxide is 25-65ppm, is the 1/10-1/20 of coal-fired utility.Because the efficiency of energy utilization of user side is high, real minimizing carbon dioxide isothermal chamber gas purging.Gas turbine generating itself does not need substantially with water, and required water is all that water-saving performance is fabulous for heat supply.
Although hot and cold, chp system exists above-mentioned advantage, still there is following shortcoming in existing hot and cold, chp system: one is hot and cold, chp system small scale, is arranged in building, can only uses natural gas or oil product; Although two are hot and cold, chp system scales than big power station and large-scale cogeneration of heat and power little, but is produced from small-sized hot and cold, Electricity Federation littlely can not install one to single household, hot and cold, the CCHP of a building Huo Yige community, building can only be adapted to, flexible unlike small-sized household air-conditioner, family water heater or family space heater.
Therefore, for the shortcoming that current small-sized hot and cold, electric system exists, the utility model proposes a kind of novel hot and cold, cogeneration system, use cryogenically heat energy and solar association to drive.This kind of system, under the prerequisite of advantage having hot and cold, the electric combined supply system of tradition, can also be broken away from the dependence of traditional combined supply system to natural gas, the oil product energy, rely on the coupling of the multiple low grade energy, improve the utilization rate of the energy; Realize the zero-emission of pollutant, the propelling of energy-saving and emission-reduction is had great importance.
The utility model adopts geothermal energy.The utilization of geothermal energy can be divided into geothermal power generation for now and directly utilize two large classes, is approximately 7000MW ~ 8500MW in the world at present for the geothermal energy resources generated electricity and directly utilize.As shown in table 1, geothermal energy resources can be divided into high temperature, middle gentle low temperature three class by temperature.The underground heat that temperature is greater than 150 DEG C exists in vapour form, is high-temperature geothermal; The underground heat of 90 DEG C-150 DEG C exists with forms such as the mixtures of water and steam, is middle temperature underground heat; Temperature is greater than 25 DEG C, is less than the underground heat of 90 DEG C with form existence such as warm water (25 DEG C-40 DEG C), warm water's (40 DEG C-60 DEG C), hot water (60 DEG C-90 DEG C), is low temperature underground heat.
