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 anti-frosting 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.Air source hot pump water heater utilizes contrary Carnot's principle, 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 environment temperature dependence is excessive to external world for the air source hot pump water heater of prior art, and in use frosting easily influences performance and service life.
The utility model content

The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, operation realizes uninterrupted hot-water supply under low temperature environment; 3, defrost is effective, and defrost goes out 5% of water inventory with hot water is no more than, does not influence leaving water temperature.4, environment above zero can be realized frostless operation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the inner partial structurtes schematic diagram of the utility model embodiment heating water tank.
Fig. 3 is the structural representation of the utility model embodiment restricted baffle.
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, heat(ing) coil 3, supercooling tube group 4, check valve 5, gas-liquid separator 6, outdoor radiator 7, aerofoil fan 8 and defroster 9.
Compressor 2, heat(ing) coil 3, supercooling tube group 4, check valve 5, gas-liquid separator 6, outdoor radiator 7 usefulness copper pipes are concatenated into a closed circuit, are equipped with to act as the working medium of transmitting heat in this closed circuit.
Aerofoil fan 8 adopts speed change to become the 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 radiator 7 surperficial air, increases the heat exchange amount, thereby reduces the frosting area of operation under outdoor radiator 7 low temperature environments; Keep the low cruise state when environment temperature is too high,, prevent that compressor 2 is overheated to keep the evaporating temperature and the evaporating pressure of refrigeration working medium.Aerofoil fan 8 cooperates with outdoor radiator 7, and outdoor radiator 7 is played heat radiation.
On the pipe between pressure-relief valve 12 and the hot water effluent's interface 31, be connected with three-way connection 15, on three-way connection 15, be connected with frost-free means 9 with pipe.Frost-free means 9 comprises defrost diaphragm valve 91 and the spray equipment 92 that is chained together with pipe, and defrost diaphragm valve 91 is connected with three-way connection 15, and spray equipment 92 is positioned at the top of outdoor radiator 7.Do the time spent, the hot water that sprays out in heating water tank 1 from spray equipment 92 drenches on outdoor radiator 7, the temperature of outdoor radiator 7 is raise, the effect of played defrost, preventing frosting, the frostless operation of unit.
Controller adopts single-chip microcomputer, and input is for inserting the temperature sensor in the water tank 1, the start and stop of output control compressor 2, aerofoil fan 8 and frost-free means.Controller can be installed on the shell of heating water tank 1, also can independently install on the wall.Can present embodiment be set at the basic operational mode of temperature difference control and the economic operation model that is jointly controlled by the clock and the temperature difference by controller.
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 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 is discharged.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, send into gas-liquid separator 6 after forming the low-pressure low-temperature steam, 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.Outdoor radiator 7 temperature are lower than 5 when spending, 91 conductings of defrost diaphragm valve, the hot water that sprays out in heating water tank 1 from spray equipment 92 drenches on outdoor radiator 7, and the temperature of outdoor radiator 7 is raise, remove the frost on the outdoor radiator 7, realize the omnidistance frostless operation of unit.
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.
