The specific embodiment
The specific embodiment to this hot water apparatus describes in conjunction with the accompanying drawings.
As accompanying drawing 1, this highly effective air source heat pump hot water device includes the air source heat pump type water heater of being made up of compressor 1, expansion valve 2, air surface cooling heat exchanger 3 and refrigerant pipe heated type boiler 4 and the refrigerant pipe that is used to be connected.Its compressor 1 adopts the low back pressure type cryogenic compressor that is suitable for the low temperature environment operation, and it is all kinds condensation heat release formula heat exchanger of medium with the cold-producing medium that boiler 4 can be selected double pipe heat exchanger type, vertical or horizontal shell coiled and shell-type helix tube etc.Described air surface cooling heat exchanger 3 disposes two groups of cold-producing medium coil pipes of a, b, wherein a group cold-producing medium coil pipe constitutes hot water heating and cooling agent loop through the cold-producing medium coil pipe that refrigerant pipe connects compressor 1, expansion valve 2 and boiler 4, and b group cold-producing medium coil pipe connects compressor 1, expansion valve 2 and a group cold-producing medium coil pipe through refrigerant pipe and constitutes the non-heated condition compressor operating of boiler refrigerant loop.Constitute heat exchanger 3 defrosting running refrigerating agent loops by refrigerant pipe connection compressor 1, a group cold-producing medium coil pipe.
As accompanying drawing 2, this hot water apparatus is serially connected with bathroom heating surface cooling heat exchanger 11 in the refrigerant line between compressor 1 and boiler 4 on the basis of accompanying drawing 1 embodiment.
As accompanying drawing 1, accompanying drawing 2, the conversion of each cold-producing medium operating loop of this hot water apparatus is finished by the conversion valve 5,6,7,8,9,10 that is disposed in the refrigerant line.
As accompanying drawing 3 and accompanying drawing 4, be provided with different water temperatures waters demarcation strip 12 in the case in the boiler 4 of the present utility model, so that form in the water tank by the high-low-temperature zone of cooling water inlet end to the hot water outlet end, avoid hot and cold water directly to mix, improve the water efficiency of heating surface, guarantee that the water tank hot water exit has hot water stable and that meet the requirements temperature.
The operation principle of this highly effective air source heat pump hot water device is as follows:
As accompanying drawing 1, the high-temperature gas cold-producing medium that compressor 1 is discharged through valve 5 to the condensation of refrigerant heating tube of boiler 4 to water tank in the water heating, condensed liquid refrigerant enters a group cold-producing medium coil pipe of surface cooling heat exchanger 3 to expansion valve 2 throttlings through valve 6, liquid refrigerant absorbs heat in the air through the evaporation of a group cold-producing medium coil pipe, and the cold-producing medium that becomes gaseous state is back to compressor to be continued compression and repeat the above-mentioned boiler condensation heating work circulation that puts hot water.After water temperature reaches set water temperature in the boiler; valve 7,8 is opened; close through time- delay valve 5,6; the high-temperature gas cold-producing medium is by the b group cold-producing medium coil pipe of valve 7 to heat exchanger 3; after evaporating, a group cold-producing medium coil pipe absorbs airborne heat to expansion valve 2 throttlings through valve 8 again; the cold-producing medium that becomes gaseous state after the evaporation heat absorption is back to compressor 1 and continues compression, carries out the compressor of the non-heated condition of boiler and does not shut down operation.When carrying out the non-heating of water tank operation, compressor should be by VFC with the frequency limitation of compressor in low-limit frequency or be offloaded under the minimum load and move, to reduce the power consumption of compressor.When 3 frostings of table cold heat exchanger, valve 7,8 is closed, and valve 9 is opened, and the high-temperature gas cold-producing medium is organized the cold-producing medium coil pipe through a that valve 9 enters table cold heat exchanger 3, carries out defrosting with condensation heat.Its defrosting operation should be finished at short notice, so that in time change the heating operation to boiler over to.
The operation principle of accompanying drawing 2 is identical with accompanying drawing 1, its difference is to have installed a small-sized bathroom heating heat exchanger 11 between the refrigerant pipe of compressor 1 and boiler 4 additional, the high-temperature gas cold-producing medium that its compressor 1 is discharged is introduced into bathroom heating heat exchanger 11 through valve 5, condensation heat earlier to bathroom heating heating, is entered boiler through valve 10 again water is heated.When the boiler water temperature reaches design temperature or temporarily stops bathing need stopping water being heated the time, after the high-temperature gas cold-producing medium enters 11 heating of bathroom heat exchanger, finish through valve 7 to b group cold-producing medium coil pipes condensation heat is discharged to airborne operation, close after valve 10 time-delays this moment.After increasing bathroom heating heat exchanger 11, the fouling that can alleviate boiler 4 heat(ing) coils.
Expansion valve that the utility model uses should adopt electric expansion valve.
The used air surface cooling of the utility model heat exchanger when indoor, also can adopt the band fin or the fin serpentine coil formula natural convection air heat exchanger that do not dispose blower fan as being installed in.
