Description
Technical field
The utility model relates to a kind of air source hot pump water heater, particularly relates to a kind of air source hot pump water heater with flexible defrost function.
Background technology
Air source hot pump water heater claims Teat pump boiler again, produces hot water by absorbing air heat source, and energy-saving efficiency is more than 4 times of electric heater, and is also more energy-conservation than solar water heater, is the most advanced in the world at present energy-saving environment-friendly hot water system.The contrary Carnot's principle of air source hot pump water heater, with few electric energy, absorb a large amount of low temperature heat energy in the air, compression by compressor becomes high temperature heat, transfer to water tank, heat hot water, so its energy consumption is low, efficient is high, speed is fast, security is good, the feature of environmental protection is strong, hot-water supply endlessly.It has the advantage that is difficult to compare as hot-water heating system.
But the air source hot pump water heater of prior art often only is provided with a heating water tank, makes that to add thermal effect bad, and thermal conversion efficiency is low.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design, the air source hot pump water heater with flexible defrost function that defrosting effect is good are provided.
The technical scheme in the invention for solving the above technical problem is: a kind of air source hot pump water heater with flexible defrost function comprises heating water tank, compressor, four-way control valve, output heat exchanger, supercooling tube group, heats check valve, gas-liquid separator, outdoor radiator and aerofoil fan; It is characterized in that: comprise that also defrost magnetic valve and heat of compressor reclaim coil pipe; Described defrost magnetic valve is connected gas-liquid separator and heats between the check valve; Described heat of compressor reclaims coil pipe and is connected between four-way control valve and the outdoor radiator.
The described heating water tank of the utility model is provided with into water interface, is in series with pressure-relief valve, filter, ball valve successively with pipe on the water inlet interface.
The described heating water tank of the utility model is provided with the water outlet interface, and the pipe that is communicated with the water outlet interface is provided with the leaving water temperature sensor.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design.2, be provided with heat of compressor and reclaim coil pipe, reclaim heat of compressor, reduce thermal loss, effectively improve rate of heat exchange, reduce the working medium degree of superheat, improve the compressor return air pressure and temperature when environment temperature is low, compressor liquid refrigerant can not occur and return the liquid phenomenon, the frosting critical-temperature increases, and the low-temperature heating state keeps reliability service and reduces the defrosting number of times down; Can give the cooling of compressor winding when environment temperature is high, avoid the generation of compressor damage phenomenon.3, aerofoil fan 8 adopts multi-change speed axial flow motor, and environment temperature is crossed and entered the state of running up when hanging down, and to increase the convection current of outdoor spreader surface air, increases the heat exchange amount, thereby reduces the frosting area of operation under the outdoor radiator low temperature environment; Keep the low cruise state when environment temperature is too high,, prevent the overheat of compressor protection to keep the evaporating temperature and the evaporating pressure of refrigeration working medium.4, be provided with defrost magnetic valve 9, can reach the effect of flexible defrosting.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1, the utility model embodiment comprises heating water tank 1, compressor 2, output heat exchanger 3, supercooling tube group 4, heat check valve 5, gas-liquid separator 6, outdoor radiator 7, aerofoil fan 8, defrost magnetic valve 9, four-way control valve 10 and heat of compressor reclaims coil pipe 11.
Four-way control valve 10 reclaims coil pipe 11 usefulness pipes and is connected connection with compressor 2, output heat exchanger 3, gas-liquid separator 6, heat of compressor respectively.Defrost magnetic valve 9 usefulness pipes turn on gas-liquid separator 6 and heat between the check valve 5.
Aerofoil fan 8 adopts multi-change speed axial flow motor, cooperates with outdoor radiator 7, and outdoor radiator 7 is played heat radiation.
The operation principle of the utility model embodiment: the working medium that is the high temperature and high pressure gas shape that compressed machine 2 is discharged enters heat(ing) coil 3 in the heating water tank 1 by four-way control valve 10 and makes water in the thermal source heating heating water tank 1, the working medium that is positioned at pipe in heating process is emitted heat, temperature reduces, and further condensing into liquid, the heat(ing) coil 3 from heating water tank 1 flows out.During high-pressure working medium liquid process supercooling tube group 4, pressure is descended, cause the gasification of part working medium, absorb gasification latent heat, make the also corresponding reduction of itself temperature, become the damp steam under the low-temp low-pressure, the outer radiator 7 of inlet chamber.Worker quality liquid absorbs airborne heat and solar radiant heat and gasifies in outdoor radiator 7, forms to send into heat of compressor behind the low-pressure low-temperature steam and reclaim coil pipe 11.And then enter gas-liquid separator 6 through four-way control valve 10, and gas-liquid separator 6 will be in the working medium of liquid condition to be separated with the working medium that is in gaseous state, and the working medium that is in liquid condition is siphoned away by compressor 2.So circulation endlessly.When the needs defrost, 10 actions of four-way control valve, defrost magnetic valve 9 energising is opened, and the HTHP working medium that compressor 2 is discharged is got back to compressor 2 again successively after four-way control valve 10, heat of compressor reclaim the outdoor radiator 7, defrost magnetic valve 9, gas-liquid separator 6 of coil pipe 11, frosting.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
