Abstract
The utility model discloses a kind of Novel heat pump hot water apparatus.It is comprised of compressor, plate type heat exchanger, expansion valve, water pump, air heat exchanger, ptc heater, nano-fluid etc.Be different from normal air source heat pump water heater, this installs maximum feature is that evaporimeter is divided into two parts, making essence in heat pump operation principle is water-loop heat pump, but absorb origin of heat in air, solved the shortcoming that the pressure drop of air source heat pump duplex matter system is large, heat transfer temperature difference is large, heating efficiency is on the low side.In addition, adopt nano-fluid technology, significantly improved the heat transfer coefficient of heat exchanger; Air heat exchanger is used large spacing fin, reduces frosting in winter probability; Use the heat-carrying built-in ptc heater defrosting that circulates, improve defrosting speed and effect.
Description
Technical field
The utility model relates to a kind of energy saver of heat-pump hot-water, and its core is the application of nano-fluid technology and secondary indirect heat exchange technology.
Background technology
Air source hot pump water heater has advantages of solar water heater energy-saving and environmental protection, safety, has solved again solar water heater and has relied on sunlight to adopt heat and inconvenient shortcoming is installed.Due to plurality of advantages such as height are safe, height is energy-conservation, the life-span is grown, do not discharge pollutants, and can effectively solve current domestic relevant department to saving the energy, environmental protection, security and various aspects compared with thorny problem, and day by day be subject to the extensive concern of all sectors of society.
And air source hot pump water heater is usingd air as thermal source, its Energy Efficiency Ratio (COP) with normally whether work direct relevant with the temperature of air-source.The evaporimeter of air source heat pump adopts air-cooled fin-tube heat exchanger, and the coefficient of heat transfer is lower, and heat exchanger volume is larger, causes Working fluid flow resistance larger, increases compressor load, and then reduces heating energy efficiency ratio.And winter temperature is generally difficult to reach due energy-saving effect at areas to the south, the Changjiang river air source hot pump water heater of-5 ℃, and this has limited the market space of air source hot pump water heater greatly.
The utility model improves common heat pump hot water thermal hydrophone, adopts the secondary pattern of indirectly absorbing heat, and evaporimeter is divided into two parts, although increased the energy consumption of circulating pump, has reduced Working fluid flow resistance, and heat pump compressor energy consumption declines, more energy-conservation by contrast.Adopt in addition unique antifreeze nano-fluid as heat-carrying agent, the coefficient of heat transfer is significantly improved, and can guarantee that fluid normally works in the time of-20 ℃.
Utility model content
Water-loop heat pump, nano-fluid technology, the technological synthesis of secondary indirect heat exchange are got up, in energy-conservation, solve air source hot pump water heater easy frosting in winter, defrosting difficulty, affect the problem of quality of water supply.
The nano-fluid heat-pump water heater that indirectly absorbs heat, described device comprises: heat pump compressor (1), plate type heat exchanger, expansion valve (3), water pump, air heat exchanger, ptc heater (5), nano-fluid;
Heat pump compressor (1) work makes working medium become high pressure high temperature vapor, by water-cooled condenser (2), after being provided, heat becomes high pressure supercooled liquid for hot water heating, then through expansion valve (3) throttling, become the saturated two-phase mixed state of low pressure, enter water-cooled evaporimeter (4) absorption cycle heat-carrying agent; The heat of nano-fluid becomes low area overheat steam, finally returns to compressor and enters next circulation, has realized the result that the heat of nano-fluid is shifted to hot water;
Blower fan (8) starts makes outdoor air enter air heat exchanger (7), transfers heat to nano-fluid, then provides circulation power by circulating pump (6), makes nano-fluid continuously for heat pump fluid provides heat.
Accompanying drawing explanation
By describing in more detail exemplary embodiment of the present utility model with reference to accompanying drawing, above and other aspect of the present utility model and advantage will become and more be readily clear of, in the accompanying drawings:
Fig. 1 is systematic schematic diagram of the present utility model.

The specific embodiment
Hereinafter, now with reference to accompanying drawing, the utility model is described more fully, various embodiment shown in the drawings.Yet the utility model can be implemented in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present utility model is conveyed to those skilled in the art fully.
Hereinafter, exemplary embodiment of the present utility model is described with reference to the accompanying drawings in more detail.
In Fig. 1, heat pump compressor 1 work makes working medium become high pressure high temperature vapor, by water-cooled condenser 2, after being provided, heat becomes high pressure supercooled liquid for hot water heating, then through expansion valve 3 throttlings, become the saturated two-phase mixed state of low pressure, enter that water-cooled evaporimeter 4 (plate type heat exchanger) absorption cycle heat-carrying agent---the heat of nano-fluid becomes low area overheat steam, finally return to compressor and enter next circulation, realized the result that the heat of nano-fluid is shifted to hot water.
Blower fan 8 starts makes outdoor air enter air heat exchanger 7, transfers heat to nano-fluid, then provides circulation power by circulating pump 6, makes nano-fluid continuously for heat pump fluid provides heat.Nano-fluid has antifreeze feature, and climatic adaptation ability is strong; Heat transfer coefficient is high, greatly improves the whole Energy Efficiency Ratio of device.
Ptc heater 5 is only used during air heat exchanger frosting in the winter time.Normal air source heat pump to melt frost generally adopts the method for working medium reverse circulation, need to absorb heat from high temperature heat source (as hot water), causes hot water temperature to be fluctuateed larger, affects quality of water supply.And adopt PTC heating, and for after defrosting provides heat, also can be evaporimeter heat is provided, make heat pump maintenance work, guarantee that hot water temperature is constant.
The foregoing is only embodiment of the present utility model, be not limited to the utility model.The utility model can have various suitable changes and variation.All any modifications of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
