Exchanger, condensate collector and subcooler, the condensed water that the air-cooled heat exchanger generates, into the condensation water collection
Device, the condensed water enter subcooler, the subcooler connection heating expansion valve and heating solenoid valve；The heating expansion valve and
The heating recycle system of heating solenoid valve connection air source hot pump water heater.
Preferably, the subcooler is equipped with refrigerant inlet, refrigerant outlet, condensation water inlet and condensation-water drain.
Preferably, the condensed water discharge after the condensation-water drain will heat up.
Preferably, the heating recycle system further include oil-to-water heat exchanger, it is solenoid operated four-way valve, gas-liquid separator, unidirectional
Valve, refrigeration expansion valve, refrigeration solenoid valve, liquid storage device and device for drying and filtering.
Preferably, the air cooling fin of the air-cooled exchanger generates condensed water.
Preferably, the subcooler uses coaxial heat exchanger.
The beneficial effect of the utility model compared with prior art is: using the condensed water of air cooling fin, can also cry " useless

Detailed description of the invention
Fig. 1 is the system structure diagram of the utility model specific embodiment；
Fig. 2 is the subcooler structural schematic diagram of the utility model specific embodiment；
Fig. 3 is the existing system structural schematic diagram of the utility model specific embodiment.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, specific embodiment of the utility model, including air-cooled heat exchanger, condensate collector and
Subcooler, the condensed water that air-cooled heat exchanger generates, into condensate collector, condensed water enters subcooler, subcooler connection
Heat expansion valve and heating solenoid valve；Heating expansion valve connects the heating cyclic system of air source hot pump water heater with heating solenoid valve
System.
Further, subcooler is equipped with refrigerant inlet, refrigerant outlet, condensation water inlet and condensation-water drain.
Further, the condensed water discharge after condensation-water drain will heat up.
Further, heating recycle system further include oil-to-water heat exchanger, solenoid operated four-way valve, gas-liquid separator, check valve,
Refrigeration expansion valve, refrigeration solenoid valve, liquid storage device and device for drying and filtering.
Further, the air cooling fin of air-cooled heat exchanger is an evaporator, generates condensed water.
In Teat pump boiler refrigerant circulating process, air cooling fin is an evaporator, absorbs the heat in air, warp
The air for crossing air cooling fin will cool down, and close to the dew point of air, just have liquid water precipitation.The operative liquid water is gathered up
Come, flows back into refrigerant cooling circuit, liquid refrigerant is subcooled, be then discharged out.
The temperature of this part water is at 28 DEG C hereinafter, and calcic, magnesium ion, subcooler do not have the risk of fouling.It can incite somebody to action
Degree of supercooling promotes 2-3 DEG C, and heat efficiency promotes 1.5%.Air cooling fin condensation water recovery and use.
Subcooler uses coaxial heat exchanger, and refrigerant is from refrigerant inlet into going out from refrigerant outlet, and condense water inlet
Make to condense hydrothermal exchange with condensation-water drain, and the condensed water after will heat up exhausts.
This air energy heat pump water heater is absorbed heat from Cryogenic air, is then transferred into the water tank of high temperature, by hot water
Standby rear use is stored in water tank, in principle, it is identical as refrigeration machine is worked according to inverse Carnot cycle principle,
Structural schematic diagram as depicted in figs. 1 and 2, the improvement of the progress on existing system structural representation Fig. 3.
When this air source hot pump water heater system normal circulation, generally can all there be certain degree of supercooling in the outlet of condenser.
If liquid in the two-phase refrigerant pressure in " liquid pipe " is slightly lost without degree of supercooling, liquid will shwoot, that is, be saturated
Liquid will necessarily be evaporated due to the reduction of pressure.Liquid evaporation can absorb the heat of surrounding, and remaining liquid cools down therewith, and reaches
Saturation temperature under to relevant pressure, two-phase refrigerant side is advanced like this, side shwoot, side saturation, until reaching evaporator inlet.
The mass dryness fraction for eventually arriving at the two-phase refrigerant of evaporator will be more much larger than the mass dryness fraction of design, and liquid phase ingredient reduces, and is just unable to satisfy
The evaporation capacity of evaporator, refrigeration effect can reduce certainly.The prior art guarantees 3-5 DEG C of supercooling using economizer is increased
Degree, refrigeration effect are not so good.
The utility model uses the condensed water of air cooling fin, can also be " useless cold " recycling, increases subcooler and replaces warp
Help device, and structure is simple, reduces refrigeration cost, improves heating efficiency and heating capacity, meets low-carbon environment-friendly demand instantly, is promoted
Air source hot pump water heater operational efficiency solves the condenser mistake used in air source hot pump water heater present in the prior art
Low, the low technical problem of Energy Efficiency Ratio of cold degree.
The foregoing is merely this patent preferred embodiments, not limit this patent range, all using specification and attached
Equivalent structure or equivalent flow shift made by figure content is directly or indirectly used in other relevant technical fields, belongs to
The scope of this patent.
