Description
Technical field
The present invention relates to a kind of heat-pump water heater, more particularly relates to a kind of air-source heat pump water heater.
Background technology
Air-source water heater, also referred to as " air source hot pump water heater ", it is that the low-temperature heat quantity in air is absorbed into come, passes through
Fluorine medium gasifies, and is then heated up by being pressurized after compressor compresses, then converts feedwater heating, the high temperature after compression by heat exchanger
Heat energy heats water temperature with this.Air-source water heater has the characteristics of energy-efficient, manufactures identical hot water amount, is general electric heating
4-6 times of hydrophone, its annual thermal effect ratio is electrically heated 4 times, utilizes efficiency height.But current air-source water heater exists
During winter operation, because outdoor temperature is relatively low, system evaporability is limited, refrigerant not evaporating completely in evaporator, causes
Fraction of liquid is had in into compressor, can now form liquid hit phenomenon, causes the service life reduction of compressor, system operation
Stability weakens；Meanwhile under worst cold case air energy heat pump water heater heating capacity it is low, firing rate is slow, easy frosting is whole
Industry problem encountered.
The content of the invention
Goal of the invention：Present invention aims in view of the shortcomings of the prior art, there is provided one kind prevents liquid hammer, slows down frosting
The air-source heat pump water heater with inflation type heat exchanger.
Technical scheme：A kind of air-source heat pump water heater with inflation type heat exchanger of the present invention, including water tank and
Outdoor unit, the water tank is interior to set condenser, and the outdoor unit includes compressor, heat exchanger and flow controller, the compressor
Outlet is connected with the entrance of the condenser, and the outlet of the condenser is connected by the flow controller with the heat exchanger, institute
It is inflation type evaporator to state heat exchanger.
Technical solutions of the utility model are further defined to, and the outdoor unit also includes Fin and tube evaporator, the pipe
Wing formula evaporator is arranged between the flow controller and the heat exchanger.
Further, the condenser is arranged at the internal or external of the water tank.
Further, the flow controller is electric expansion valve.
Beneficial effect：The utility model discloses a kind of air-source heat pump water heater with inflation type heat exchanger, is placed in room
The heat exchanger of outer machine is inflation type evaporator, beneficial to increase disengagement area, in summer operation, outdoor temperature is higher and sunshine compared with
Sufficient and abundant, now evaporation efficiency is higher, and the operational energy efficiency of system is higher, more saves；Using inflation type heat exchanger and heat
The outer machine of pump combines, and refrigerant is introduced into Fin and tube evaporator and enters back into inflation type evaporator, refrigerant can be completed to flash to saturation
Gas or overheated gas, it is more favourable to compressor, prevent the situation of liquid hammer；The utility model by inflation type heat exchanger with
The outer machine of heat pump is combined, and the maximization of disengagement area can be realized in limited space, so that the vapor pres- sure of whole system
Power is obviously improved, and evaporating temperature rise, bigger so as to recept the caloric, the speed of frosting is slower, and the cycle is longer, the defrosting week of system
Phase also can be elongated, and power consumption is smaller.

Embodiment
Technical solution of the present invention is described in detail below by accompanying drawing, but protection scope of the present invention is not limited to
The embodiment.
Embodiment 1：A kind of air-source heat pump water heater with inflation type heat exchanger, its structural representation as shown in figure 1,
Including water tank 2 and outdoor unit 7.
Condenser 3 is set in the water tank 2, and water tank 2 mainly includes inner bag, and condenser 3 is internal or external at inner bag.
Outdoor unit 7 includes compressor 1, heat exchanger 6 and flow controller 4.The outlet of the compressor 1 and the condenser 3
Entrance is connected, and the outlet of the condenser 3 is connected by the flow controller 4 with the heat exchanger 6, and the flow controller 4 is electronics
Expansion valve, the heat exchanger 6 are inflation type evaporator, and the structural representation of the inflation type evaporator is as shown in Figure 3.Inflation type
Heat exchanger mainly answers aluminium sheet by forming inflation type evaporator after the steps such as the annealing of aluminium sheet, roller brush, printing, cladding plate, hot rolling,
Processing technology is ripe, and easy to operate, stream is easily realized, and cost is not high, while can be bent into according to demand different
Shape.
In addition, in the present embodiment, the outdoor unit 7 also includes Fin and tube evaporator 5, and the Fin and tube evaporator 5 is set
Between the flow controller 4 and the heat exchanger 6, the structural representation of the Fin and tube evaporator 5 is as shown in Figure 2.
During a kind of work for air-source heat pump water heater with inflation type heat exchanger that the present embodiment provides, compressor 1
The high steam of discharge enters in the condenser 3 in water tank 2, after the water heat exchange in water tank, forms highly pressurised liquid, passes through electronics
The throttling action of expansion valve 4, low-pressure gas-liquid mixed state is formed, is introduced into the evaporator 5 of outdoor unit 7 and enters inflation type heat exchanger again
In, the heat in absorption air, low-pressure steam is formed, finally enter and a circulation is formed in compressor 1.
Using the present embodiment, have the advantages that：
（1）Heat exchanger 6 is inflation type evaporator, is advantageous to increase disengagement area, when heat transfer temperature difference is environment temperature and is changed
The hot timing of coefficient one, heat exchange area is bigger, then heat exchange amount is higher, therefore efficiency is higher, especially in summer operation, outdoor temperature
Higher and sunshine is relatively sufficient and abundant, and now evaporation efficiency is higher, and the operational energy efficiency of system is higher, more saves.
（2）Liquid hammer can be prevented to a certain extent by being combined by inflation type heat exchanger with machine outside heat pump：Normal conditions
Under, when air energy heat pump water heater is run in the winter time, because outdoor temperature is relatively low, system evaporability is limited, and refrigerant is evaporating
Not evaporating completely in device, causes to enter in compressor and has fraction of liquid, can now form liquid hit phenomenon, cause compressor
Service life reduction, the stability of system operation weakens.
（3）Combined using inflation type heat exchanger with machine outside heat pump, refrigerant is introduced into Fin and tube evaporator and enter back into inflation
Formula evaporator, refrigerant can be completed to flash to saturated gas or overheated gas, more favourable to compressor.Pass through inflation type heat exchanger
Frosting can be slowed down by being combined with machine outside heat pump, the heating capacity of air energy heat pump water heater is low under worst cold case, firing rate is slow,
Easy frosting is whole industry problem encountered.By both effective combinations, evaporating surface can be realized in limited space
Long-pending maximization, so that the evaporating pressure of whole system is obviously improved, evaporating temperature rise is bigger so as to recept the caloric, knot
The speed of frost is slower, and the cycle is longer, and the defrosting cycle of system also can be elongated, and power consumption is smaller.
As described above, although the present invention has been represented and described with reference to specific preferred embodiment, but it must not be explained
For to the limitation of itself of the invention., can be right under the premise of the spirit and scope of the present invention that appended claims define are not departed from
Various changes can be made in the form and details for it.
