Description
Technical field
The present invention relates to a kind of energy blood circulation, particularly relate to a kind of domestic distributed energy blood circulation.
Background technology
There are 1,300,000,000 people, about 700,000,000 urban populations, 200,000,000 families in China.Household electricity, disappear with heat, heat supply, the energy of refrigeration
Consumption accounts for more than the 40% of city energy.Along with stepping up of people's living standard, the requirement to house is more and more higher, house face
Long-pending the most increasing.Heat supply, cooling, cook, popularized in city and rural area with hot water etc..Current home-use energy general
All over mode it is: use electric energy air-conditioning heat supply and refrigeration, the direct combustion heat supplying of natural gas, electrothermal heater, Natural Gas Water Heater, sky
So gas directly burns and cooks.These, with can mode be all directly to consume high-grade energy, not only cause energy waste, and give
Family brings financial burden.
Energy-saving and emission-reduction are fundamental state policies of country.Greatly developing distributed energy is that national industrial policies are advocated energetically
With can mode.Particularly domestic distributed energy resource system is also in blank.Therefore, the residential energy sources system that exploitation is advanced is to joint
The living standard that can reduce discharging and provide the common people is particularly significant.Wherein, domestic distributed energy resource system is the science to residential energy sources
Change and utilize.If the energy utilization rate of traditional energy resource consumption mode is only 20 ~ 30%. employing distributed energy resource systems, its energy
Utilization rate can reach to 70%, at least improves more than 30% than the efficiency of traditional energy Land use systems.The present energy of China is total
Consume about 3,000,000,000 tons of mark coals.Wherein, home energy source consumes the most annual 1000000000 tons of mark coals, even if energy-conservation ten thousand/, every year
Amount of energy saving be also up to 1,000,000 tons mark coals more than.
Existing family substantially uses distributing energy mode, and its basic feature is as follows: 1) domestic air conditioning: directly
Use electrical energy drive operation of heat pump, to domestic heat or heating；2) domestic heat: in addition to central heating system, family is basic
Upper employing coal-burning stove for heating.Very big owing to polluting, the particularly hardly possible employing in city coal heating.But employing natural gas straight
Connect combustion heating water, then use water as medium and pass through radiator, or floor heating.3) domestic hot-water: domestic domestic hot-water is exhausted
Major part uses gas furnace manufacture hot water, some household electricity water heater hot-water supply.4) cook: urban family is cooked the most complete
Portion uses natural gas to be fuel, cooks with gas-cooker.
Mode can there is following defect in distributing: 1) domestic air conditioning is high-grade energy.China's power generation
Average energy consumption is that about 350 grams of mark coals, being equivalent to conversion efficiency of thermoelectric is 35%.Therefore, with the energy of driven by power air-conditioning waste
It is about about 60%.The particularly little air-conditioning of domestic, efficiency is lower, more wastes the energy.2) fuel gas buring temperature be up to 1000 DEG C with
On, ideal thermal efficiency (the Kano thermal efficiency), close to 80%, falls within high-grade energy.And household heating and the temperature used by manufacture hot water
Degree is only about 80 DEG C, and its Carnot efficiency is only about 16%.Virtually have lost the utilization of energy value of about 60%.Therefore,
Natural gas heat supply and the hot water for life waste energy are extremely serious.3) energy of household gas range waste is more serious.Cooking, boil
The energy efficiency of meal is also less than 20%, if it is considered that the decline of energy quality, the usable value of natural gas is about about 10%.
In sum, household electricity, with heat and the lowest by the utilization rate of gas.About about 20 ~ 30%.If able to
According to the thermodynamic (al) basic theories scientific utilization energy, having a high potential of household energy conservation.Greatly facilitate energy-saving and environmental protection and minimizing
Home energy source is paid wages.

The operation principle of the present invention is as follows:
Gas electricity generator 3, gas electricity generator 3 electricity is entered through gas control valve 2 from combustion gas storage tank 1 combustion gas out
Utility network is entered through domestic distribution system.The flue gas that another road is discharged from gas electricity generator 3, typical temperature is 500 ~ 550
℃.This part of waste heat enters Household residual heat utilization system.A portion waste heat enters absorption by residual heat pump control valve 6
Heat pump 7, as the drive energy of absorption heat pump 7.Absorption heat pump 7 produces heat source after absorbing fume afterheat, or
The low-temperature receiver of refrigeration.For fan coil system, heat or cold that absorption heat pump 7 provides can directly pass through fan coil 9
Enter coil pipe heat supply/refrigeration terminal 10.For using the room of floor heating/radiator 12, it is only used for heat supply, and cannot be used for supplying
Cold.
The flue gas discharged from absorption heat pump 7, still has the temperature of 200 DEG C.This part energy is controlled by heat pump waste heat
Valve 14 enters hot-water heater 18, and as a part of energy of heat hot water, after heat exchange, flue-gas temperature drops to 80
About DEG C, enter air through chimney 20.
From another part of the flue gas of gas electricity generator 3 discharge by waste heat life control valve 5, entrance directly heats and is
System.Wherein, cook, cooking time family necessary.The flue-gas temperature discharged due to gas electricity generator 3 reaches more than 500 DEG C.Cause
This, can be entered by flue gas control valve 16 of cooking with the waste heat of gas electricity generator 3 and cook cooker 17, and for cooking, cooking provides
Thermal source.For cooking, flue gas that cooking is later enter hot-water heater 18, provide a part of thermal source for hot water for life.
For the part that life heat is inadequate, waste heat life control valve 5 and gas bypass valve 15 can be passed through by a part
The waste heat of gas electricity generator 3 is sent directly in hot-water heater 18 as a part of thermal source, reaches to meet the purpose of life heat.
Absorption heat pump 7 waste heat, the waste heat of cook waste heat and bypath system are simultaneously introduced hot-water heater 18, and from hot water
The hot water that case 19 introduces carries out heat exchange, makes the water circulating-heating of boiler 19.Hot water in boiler 19 may be used for having a bath, washing
Dish, laundry and other household use.For being fitted without the family of absorption heat pump 7, the hot water in boiler 19 was gone back in winter
May be used for the heat supply in heater room.
The present invention is used to utilize energy saving of system more than 50% than domestic traditional energy, the most energy-conservation 3.5 tons of marks of each family
Coal.Each family year generating income about 9000 yuan, substantially with the natural gas appropriate litigation fees consumed.Remove the natural gas that generating is multiplex
Expense, each family reduces heat supply, refrigeration and gas for domestic use more than 5000 yuan, significantly reduces the financial burden of family, improve
The quality of the life of people.
