The specific embodiment
Referring to figs. 1 through Fig. 4, the utility model discloses a kind of outer disc type air source water heater, comprise press-bearing water tank 3 and coiling outer coil pipe 23 thereon, the outer wall of described press-bearing water tank 3 is provided with spiral groove 22, described outer coil pipe 23 is arranged in the groove 22 of outside, and the contact area of outer coil pipe 23 and this groove 22 is greater than the surface area of 1/2nd outer coil pipes 23.
As shown in the figure, in present embodiment, formed groove 22 by compacting to press-bearing water tank, this groove 22 has a curved bottom 21 and is positioned at the arc-shaped transition portion 211 of curved bottom 21 both sides, what outer coil pipe 23 adopted is pipe, by the pipe that is installed in the groove 22 is pushed, make pipe have the cambered surface 231 that cooperates with the curved bottom 21 and the arc-shaped transition portion 211 of groove 22, this cambered surface 231 fits tightly together with curved bottom 21 and arc-shaped transition portion 211.Thereby make the contact area of outer coil pipe and water tank bigger, surpassed 1/2nd, reach best heat-transfer effect.Curved bottom 21 is an arc surface, thereby 23 employings of outer coil pipe is pipe, because tubing on the market mostly is pipe greatly now, and purchase and supporting easily, and also fluid is best in the pipe internal mobility.Certainly, above-mentioned be of the present utility model one preferred, curved bottom 21 and the arc-shaped transition portion 211 that is positioned at curved bottom 21 both sides also can be other smooth cambered surfaces such as elliptical arc surface.Further, 23 in groove 22 and outer coil pipe are provided with heat-conducting glue 24, and heat-conducting glue has been eliminated the minim gap of 22 of outer coil pipe 23 and grooves, has improved heat exchange efficiency.
As shown in the figure, in present embodiment, press-bearing water tank 3 comprises first water tank 25 and second water tank 26 that links to each other with first water tank 25 by pipeline, first water tank 25 and second water tank 26 are installed in the square outer container 27, be filled with insulation material in the square outer container 27, described outer coil pipe 23 coils on first water tank 25 and second water tank 26.The not only convenient of said structure placed or hung, and reduces floor space.
As shown in the figure, the utility model comprises that also one increases enthalpy heat exchanger 6 and increases enthalpy compressor 1 with this increases that enthalpy heat exchanger 6 links to each other, the outlet of described outer coil pipe by reservoir and filter with increase the enthalpy heat exchanger and link to each other, the inlet of described outer coil pipe links to each other with the output that increases the enthalpy compressor by cross valve.Because air source water heater the season of cold general efficient can decrease, in order to improve heating capacity in cold season, system has used and has increased enthalpy compressor 1, and use increases the enthalpy heat transfer technology, accomplish both to have increased the degree of supercooling of system, also realized the two stages of compression of separate unit machine, made air source water heater when low temperature environment, use ability to strengthen greatly.Especially, the utility model has adopted micro computer to manage control, and intelligent degree height is installed and used more convenient.
Referring to Fig. 1, outer disc type air source water heater system principle is as follows, and outer disc type air source water heater includes and increases enthalpy compressor 1, cross valve 2, press-bearing water tank 3, reservoir 4, filter 5, increases compositions such as enthalpy heat exchanger 6, magnetic valve 7, check valve 8, throttling arrangement 9 and 10, air-cooled evaporimeter 11, gas-liquid separator 12.Enter press-bearing water tank 3 from increasing the HTHP cold media gas that enthalpy compressor 1 comes out by cross valve 2, carry out heat exchange, make water temperature be raised to the needed temperature of domestic hot-water (general 45 ℃～60 ℃), use so that life to be provided with water in water tank.The cold media gas of HTHP is after press-bearing water tank 3 heat absorptions, and cooling becomes HTHP refrigerant liquid through reservoir 4 and filter 5, is divided into two-way then.Major loop is through increasing enthalpy heat exchanger 6, and the low-temp low-pressure refrigerant with minor loop in increasing enthalpy refrigerant heat exchanger 6 carries out heat exchange, and temperature decreases, and degree of supercooling increases.Go into air-cooled evaporimeter 11 and evaporate through main throttling arrangement throttling is laggard then, the low-temp low-pressure cold media gas that is come out by air-cooled evaporimeter 11 after entering gas-liquid separator 12 and separate by cross valve, is got back to and is increased enthalpy compressor 1 and finish a circulation.The HTHP refrigerant liquid of minor loop enters time choke valve 10 through magnetic valve 7 earlier, through the low-temp low-pressure refrigerant of throttling during increasing enthalpy heat exchanger 6 and the HTHP refrigerant of major loop carry out heat exchange, the cold media gas that flashes to preference temperature in increasing the enthalpy heat exchanger is through check valve 8, sucked by the middle gas supplementing opening that increases enthalpy compressor 1, the coolant quantity of minor loop is controlled automatically by magnetic valve 7.Increase enthalpy compressor 1 cold media gas that the gas of major loop and minor loop is collapsed into HTHP is discharged, carry out next one and circulate.
Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe; but embodiment of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
