Description
Technical field
The utility model relates to air source heat pump, particularly a kind of low-temperature air source heat pump heating uniform high-efficiency at low ambient temperatures.
Background technology
Air source heat pump is also known as Teat pump boiler, and absorb air heat source hot water preparing by heat pump, energy-saving efficiency is more than 4 times of electric heater, also more energy-conservation than solar water heater, is energy-saving environment-friendly hot water system the most advanced in the world at present.
The inverse Carnot's principle of heat pump, with few electric energy, absorbs low temperature heat energies a large amount of in air, become high temperature heat by the compression of compressor, transfer to water tank, heat hot water, so its energy consumption is low, efficiency is high, speed is fast, security is good, the feature of environmental protection is strong, hot-water supply endlessly.As hot-water heating system, it has the advantage being difficult to compare, and is therefore widely used in many fields.
As swimming pool heat pump is used widely in swimming pool constant temperature field, the COP value of swimming pool heat pump under GB operating mode is general between 2.90-4.5, easily meets the demands; But environment temperature is lower than after 5 DEG C, unit efficiency starts decay, and common air source heat pump nearly all can not use at-5 DEG C; Although ultralow temperature swimming pool unit normally can heat under-15 DEG C even low temperature environment of-30 DEG C, efficiency is now also lower, generally all below 2.0.
In general, existing air source heat pump ubiquity following technological deficiency:
1, compressor easy burn-out.Current Teat pump boiler on the market generally adopts circulating heating system, this system As time goes on exposed day by day goes out this technological deficiency, namely runs under high temperature and high pressure condition, easily makes that compressor is aging, carbonization, in addition system lubrication effect is bad, causes compressor to be easily burned.
2, the easy fouling fracture of double-tube heat exchanger.The leaving water temperature of Teat pump boiler can reach 50 degrees Celsius usually, in this temperature range, water is the easiest fouling, if can not periodic cleaning heat exchanger, for plate type heat exchanger, will burst, for double pipe heat exchanger, in it, pipe could break, thus causes whole heat-pump hot-water unit to lose function!
3, fault of water pump.Water pump is the requisite equipment of circulating heating, and accumulate over a long period along with the problem such as increased frequency and incrustation scale of start and stop, the fault of water pump will highlight!
4, existing this water circulation mode of heating efficiency is lower, and valve member, pipeline are not all cleaning maintenance spare interface, and engineering staff cannot operate this work, and along with the continuous increase of use amount, energy consumption also increases year in year out, and maintenance cost is corresponding increase also.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned technological deficiency, provides a kind of Cryogenic air thermal source pump, eliminates the parts such as circulating pump, valve member, pipeline, structure is simple, easy for installation, changes mode of heating, heating Direct Uniform, makes whole unit energy-conservation more than 20%.
The utility model solves the technical scheme that its technical problem adopts: a kind of low-temperature air source heat pump, comprise boiler, condenser, compressor, evaporating heat exchanger, Intermediate Heat Exchanger, filter and reservoir, described condenser, reservoir, filter, Intermediate Heat Exchanger, evaporating heat exchanger are communicated with by pipeline successively with compressor, compressor is communicated with condenser again, the first expansion valve is provided with between filter and Intermediate Heat Exchanger, be provided with the second expansion valve between Intermediate Heat Exchanger and evaporating heat exchanger, described condenser is directly installed in boiler.
Described evaporating heat exchanger is shell-and-tube heat exchanger, and the heat exchanger tube cross sectional shape of evaporating heat exchanger is oval.
Described condenser is directly installed on boiler inner bottom part.
Described condenser and boiler are integral type structure.
The heat exchanger tube of described condenser is the compo pipe directly carrying out heat exchange with water, and compo pipe directly carries out heat exchange with water, buys or get by illegal means effect in replacement original equipment, can obtain heat higher sooner.
The beneficial effects of the utility model are: condenser is directly installed on water tank inner bottom part, and the heat exchange compo pipe of condenser, directly to cool water heating, can make the effective homogeneous heating of the water in boiler, and remove indirect heating manner, efficiency is high;
Evaporating heat exchanger adopts oval shell-and-tube heat exchanger, and aerodynamic characteristic is good, and it is low to stream resistance, and in cross-sectional area, equal situation, heat transfer perimeter is long, is conducive to conducting heat better, more compact structure;
Heat pump fluorine Cycle Unit is installed simple, and this mode of heating is not high to site requirements, and can save a series of accessories such as a lot of valve member of water circulation, pipeline, circulating pump, on-the-spot noise drops to minimum point;
Because eliminate circulating pump, hydronic mode changes, and makes whole unit operation energy-conservation more than 20%;
Maintain also simple than the mode of traditional water circulation, maintain a people at ordinary times, within 1 hour, workload all operations is complete, does not almost have maintenance cost.
