Description

The modified condenser processing method of air-source water heater

Technical field

The present invention relates to the hot water supply system in a kind of dwelling house and other places, especially the modified condenser of air-source water heater.

Background technology

Air-source water heater pollutes little and safety than general electric heater power saving and safety than fuel oil, gas heater, is not subjected to weather and the restriction of meeting optical position than solar water heater, therefore popularizes day by day in recent years.Air-source water heater mainly contains compressor, condenser, expansion valve, four critical components of evaporimeter are formed, its condenser is being undertaken the vital task of heat exchange, general condenser integral body is cylinder body at present, spiral helicine condenser pipe is arranged in the internal bladder cavity, be fixed in the internal bladder cavity by support, wall of inner container is outward an adiabator layer, outermost is a shell, condenser pipe has refrigerant inlet and outlet, condenser has the import and the outlet of water, this condenser pipe places the internal bladder cavity water body to rely on the structure of support location that 3 drawbacks are arranged: the one, and by compression involving of machine vibration, the blank area of condenser pipe is easy to wear, get loose, fracture.The 2nd, in hot water, soak easy scaliness for a long time, influence heat conduction efficiency.The 3rd, the chemical substance that may exist in the water is to the corrosion of copper condenser pipe and reduce service life.To this, " ease spring " serial air-source water heater of U.S. that Ningbo of Zhejiang An Yuan company sells makes a useful improvement, the former condenser pipe of internal bladder cavity water body that places is moved to outside the wall of inner container, and be wrapped on the whole wall of inner container outer surface with the spirality trend, this is favourable to purifying water.For making condenser pipe and wall of inner container increase contact area, be that the pipe of 0 font changes D font pipe into cross section.This new design has overcome some drawbacks that place water body to produce, but has also produced 3 new drawbacks: the one, and it is unbalanced that D shape condenser pipe inwall bears the interior pressure that compressor applies, unfavorable to service life.The 2nd, under the identical situation of diameter, the heat transference efficiency of condenser pipe unit length reduces.The 3rd, condenser pipe is long, and it is big to prolong the stroke pressure loss, also influences the energy consumption and the service life of compressor.

Summary of the invention

The objective of the invention is above-mentioned deficiency at prior art, set about from the embedding tube seat design that improves internal bladder cavity inner structure, wall of inner container, outer the moving of condenser pipe, the modified condenser processing method of a whole set of air-source water heater is provided with interpolation four aspects of heat-reflecting layer.

The present invention realizes purpose by following measure: the modified condenser processing method of this air-source water heater is taked following several measures;

Handle in the clear chamber of A, internal bladder cavity: condenser pipe in the chamber and support are cleaned out the chamber;

The processing of B, inner bladder outer wall: extrude the embedding tube seat that spiral is walked to concave outside the tank on the wall, well width is slightly larger than the outer electrical path length of the condenser pipe for the treatment of embedding, and groove depth is omited 0.5-1 times above the condenser pipe external diameter for the treatment of embedding; Be coated with the copper layer on the inner bladder outer wall;

The processing of C, condenser pipe: on the condenser pipe diameter extended line direction or have two or a slice fin on the periphery tangential direction;

The installation of D, condenser pipe: the nearly semicanal of finned condenser pipe or homogeneous tube embedded in the embedding tube seat, and condenser pipe body and fin thereof are all to be pasted mutually with inner bladder outer wall, is close to inner bladder outer wall as far as possible;

E, add and cover heat-reflecting layer: at adiabator layer and comprise between the wall of inner container of the condenser pipe that twines and be covered with the aluminium foil heat-reflecting layer.

The modified condenser of this air-source water heater, whole one-tenth drum shape, there is cold-producing medium to import and export and water entrance, outermost layer is an outer shell, it in it adiabator layer, by outer and in also have heat-reflecting layer, finned condenser pipe layer, copper coating, inner bladder outer wall successively, nearly semicanal of finned condenser pipe or full pipe embed in the embedding tube seat of indent on the inner bladder outer wall, condenser pipe and two or a slice fin is all is close to inner bladder outer wall with inner bladder outer wall pastes mutually.

The width of embedding tube seat is slightly larger than the outer electrical path length for the treatment of the embedding condenser pipe, and the degree of depth slightly surpasses 0.5-1 times of condenser pipe external diameter.

Finned condenser pipe, have two fins then on condenser pipe diameter extended line direction, have only a fin on condenser pipe periphery tangential direction.

The invention has the beneficial effects as follows that condenser pipe is embedded in interior the location firmly of embedding tube seat of inner bladder outer wall, the influence of machine vibration by compression is not very little, and is easy to wear, come off and rupture, and do not contact with water body, polluted water not, scaliness is not corroded, and does not have the unbalanced problem of pressure-bearing of D shape pipe, the setting of fin on the interpolation of heat-reflecting layer and the condenser pipe, improve heat conduction efficiency, rationally shortened condensation section length, reduced the pressure loss that prolongs journey.

The specific embodiment

The present invention is described in detail below in conjunction with embodiment and with reference to accompanying drawing: see figures.1.and.2, the present invention has done the improvement of five aspects: the one, the former condenser pipe 4 of inner bag 10 chamber water bodys that places moves on the outer wall of inner bag 10, and write off the support in the internal bladder cavity.The 2nd, the embedding tube seat 2 of distribution spirality trend on the outer wall of inner bag staving.The 3rd, the other fin 3 of establishing of condenser pipe 4 sides.The 4th, inner bladder outer wall copper coating layer 9.The 5th, add heat-reflecting layer 8.Existing division is as follows:

Handle in the clear chamber of A, internal bladder cavity: condenser pipe in the chamber and support are cleaned out the chamber, avoid the pollution of the relevant composition with plastic stent of copper pipe to water quality;

E, add and cover heat-reflecting layer: at adiabator layer and comprise between the wall of inner container of the condenser pipe that twines and be covered with heat-reflecting layer.

The modified condenser of this air-source water heater, whole one-tenth drum shape, there is cold-producing medium to import and export and

water entrance

1 and 5, outermost layer is 6 layers on a shell, it in it

adiabator layer

7,4 layers of the condenser pipes, copper coating 9, the inner bladder outer wall 10 that also have heat-reflecting layer 8, band fin 3 successively, on the condenser pipe 4 near semicanals of band fin 3 or the full pipe embedding inner bladder outer wall 10 in the embedding tube seat 2 of indent, condenser pipe 4 and two or a slice fin 3 is all is close to inner bladder outer wall 10 with inner bladder outer wall pastes mutually.

The width of embedding tube seat 2 is slightly larger than the outer electrical path length for the treatment of embedding condenser pipe 4, and the degree of depth slightly surpasses 0.5-1 times of condenser pipe 4 external diameters.

The condenser pipe 4 of band fin 3, have two fins 3 then on condenser pipe 4 diameter extended line directions, have only a fin 3 on condenser pipe 4 periphery tangential directions.
