Description
Technical field
The present invention relates to air-conditioning/heat pump heating hot water system technology field.
Background technology
With the improvement of people ' s living standards, North of Yangtze River area needs heating, air-conditioning, hot water and dehumidifying.Heating system generally provides 65-75 DEG C of hot water to user, user's indoor location radiator device by municipal hot water pipe net or by gas-fired water heating boiler.Radiator device uses parallel way, is connected to hot water inlet pipe and hot water return pipe.Parallel way ensures that each radiator amount is impartial, and each radiator device temperature is basically identical.But, many cells are for various reasons, it is impossible to use central heating, user's Use out of range gas price is expensive, and heat pump heating is the mode of very energy-conservation.But, Railway Project is run into using air source heat pump heating at present, current technology still has some deficits.Current small-sized heat pump, outside the heat pump of removing carbon dioxide gas working medium, general leaving water temperature is limited to less than 55 DEG C, radiating mode is restricted within doors, it is general to use floor heating mode, because the water temperature of floor heating is at 30-40 DEG C, the radiator area of equal heating load is bigger than high-temperature water heating system during using wall-hanging radiator；The problem at key is that weather is colder, and heating amount demand is bigger, and heat pump efficiency is lower, it is impossible to matched with heat demand, the solution of current industry is to use electricity auxiliary heating, i.e., electric heater is connected on heat-pump hot-water export pipeline.Although auxiliary electrical heater can provide enough heat heating, radiator temperature must be raised, for example, the radiator device heat supply water temperature of design heat pump heating is 55 DEG C, 45 DEG C of return water temperature, and 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, it is 70 DEG C that mean temperature difference of being conducted heat under the premise of heat exchanger area is constant will improve 15 DEG C, i.e. heat supply water temperature, 60 DEG C of return water temperature, and in this case, heat pump has had been out heating capacity；As long as heating amount increases by 30%, heat supply water temperature is 65 DEG C, 55 DEG C of return water temperature, and heat pump is also ineffective.Certain large-scale special manufacturer of famous brand air-conditioner installs a set of heat pump floor heating air conditioning and water heating system in 150 square metres of houses of Hefei cell, because winter power consumption is very big, heating takes and takes more than one times more than hot gas heating, user has to the heat pump heating system of useless more than 140,000 yuan of installation, and change more than 10,000 yuan again and use hot gas boiler heating instead, business men general headquarters messenger repairs, and recognizes that this unit development is unsuccessful.
Hot gas boiler can only heat supply, it is impossible to cooling, has many places without combustion gas, and electricity is to popularize；Heat pump is the product of energy-conservation, can inexpensively provide tow taste heat, being capable of refrigeration air-conditioner, there is a tractor serves several purposes, the bottleneck of Winter heat supply load change can be broken through, heat pump product promotion to huge numbers of families, to improve people's quality of life, energy saving is contributed share, and this is spirit of the invention.
