Description

Family's heat pump heating air conditioning hot dehumidification combination system
Technical field
The present invention relates to air-conditioning/heat pump heating hot water system technology fields.
Background technique
As the improvement of people's living standards, North of Yangtze River area needs heating, air-conditioning, hot water and dehumidifying.Heating system 65-75 DEG C of hot water usually is provided to user by municipal hot water pipe net or by gas-fired water heating boiler, and user's indoor location radiator dissipates Hot device.Radiator device uses parallel way, is connected to hot water inlet pipe and hot water return pipe.Parallel way guarantees each heating Piece heat dissipation capacity is impartial, and each radiator device temperature is almost the same.But many cells are for various reasons, cannot use collection Middle heating, user's Use out of range gas price is expensive, and heat pump heating is very energy-efficient mode.But at present using air-source heat Pump heating encounters Railway Project, and technology still has some deficits at present.Current small-sized heat pump, outside the heat pump of removing carbon dioxide gas working medium, General leaving water temperature is limited to 55 DEG C hereinafter, radiating mode is restricted within doors, generally using floor heating mode, because of floor The water temperature of heating is at 30-40 DEG C, and the radiator area of same heating load is than high-temperature water heating side when using wall-hanging radiator Formula it is big;The problem of key is that weather is colder, and heating amount demand is bigger, and heat pump efficiency is lower, cannot match with heat demand, The solution of industry is using electricity auxiliary heating at present, i.e. electric heater connects on heat-pump hot-water export pipeline.Although auxiliary Electric heating can provide enough heat heating, but radiator temperature must increase, for example, the radiator of design heat pump heating Radiator heat supply water temperature is 55 DEG C, and 45 DEG C of return water temperature, 20 DEG C of indoor air temperature, radiator mean temperature difference is (55+45)/2 - 20=30 DEG C, and heating load 50% is improved, mean temperature difference of conducting heat under the premise of heat exchanger area is constant will improve 15 DEG C, that is, supply Hot water temperature is 70 DEG C, and 60 DEG C of return water temperature, in this case, heat pump has lost heating capacity;As long as heating amount increases 30%, heat supply water temperature is 65 DEG C, and 55 DEG C of return water temperature, heat pump is also ineffective.Certain large-scale special manufacturer of famous brand air conditioner is closing A set of heat pump floor heating air conditioning and water heating system is installed in fertile 150 square metres of houses of certain cell, since winter power consumption is very big, heating Taking is more than expense one times or more of hot gas heating, and user has to the heat pump heating systems of useless more than 140,000 yuan of installations, and changes more than 10,000 again Member uses hot gas boiler heating instead, and business men general headquarters messenger maintenance recognizes that this unit development is unsuccessful.
Hot gas boiler can only heat supply, be unable to cooling supply, there are many place do not have combustion gas, electricity is universal;Heat pump is energy-efficient Product can inexpensively provide tow taste heat, can refrigeration air-conditioner, have the advantages of a tractor serves several purposes, it is negative that Winter heat supply can be broken through The bottleneck that lotus changes, it is energy saving to contribute share to improve people's quality of life heat pump product promotion to huge numbers of families, this It is spirit of the invention.
