Description

Solar energy, air can binodal ability central heaters

Technical field

The utility model relate to a kind of have solar energy heating and air can heat the binodal of integrated application function can central heater.

Background technology

Though solar energy can be produced free hot water, in practical application, the configuration of solar energy heating has but become a relatively stubborn problem; Because sunshine in summer, duration was short during sunshine in winter, so the quantity of heat production in summer is more much more than the winter; But actual conditions be summer water few, winter, water was many, if we are by the water consumption in winter configuration solar thermal collector; So, water temperature superelevation phenomenon will appear during summer, sometimes in addition reach 100 the degree; Too the hot water of high-temperature brings fatefulue infringement not only for hot water pipe net, water tank and makes troubles to the user; More can make producing incrustation scale in the solar thermal collector, have a strong impact on the serviceability of heat collector, directly shorten the service life of complete equipment.If it is we are by the water consumption in summer configuration solar thermal collector, so, will water temperature during winter on the low side; Lean on the electrical auxiliary heater heat hot water, traditional solar energy electrical auxiliary heater load is big, and potential safety hazard is many; Operating cost is also high; Rainy weather in this way, above-mentioned various reasons brings many unsatisfactory defectives all for traditional solar water heating system.

Summary of the invention

Therefore; The purpose of the utility model be to provide a kind of can be when using summer because of the too high infringement water heater of water temperature; When winter or rainy weather, can utilize highly-efficient solar collecting again, use again air can absorb the solar energy, air of such integrated use mode heat production in the next life water of heat in the air can binodal can central heater.

The purpose of the utility model is to realize like this.

A kind of solar energy, air ability binodal ability central heater; Comprise solar heat collector, air ability heater and heat storage box; Solar heat collector comprises absorber plate and heat pipe, and air can comprise compressor, evaporimeter, condenser by heater, and condenser comprises the water coil of the usefulness of absorbing heat again; Be provided with first heat exchanger tube in the heat storage box; Said heat pipe, water coil and first heat exchanger tube form water-flow circuit, also are provided with second heat exchanger tube in the said heat storage box, and the entrance point and the port of export of second heat exchanger tube stretch out heat storage box.

Technique scheme also can be done following further perfect.

Said second heat exchanger tube is the ripple heat exchange coil.

The wall thickness of said ripple heat exchange coil is not more than 0.3 millimeter.

The entrance point of said ripple heat exchange coil is provided with filter.

The port of export of said ripple heat exchange coil is provided with heat-exchanger rig, and said heat-exchanger rig is the multiple tube of pipe in the outer tube sleeve, and interior pipe is communicated with the port of export of ripple heat exchange coil, the entrance point conducting of the gap of outer tube and interior pipe and ripple heat exchange coil.

When reaching design temperature in the time that the heat-collecting temperature of solar energy is being set, magnetic valve is opened, and running water directly gets in the solar thermal collector; High-temperature-hot-water in the heat collector is extruded and is transported in the heat storage box heat-storage medium in the heating heat storage box through pipeline, and along with constantly extruding of hot water, the heat-collecting temperature of solar energy becomes and is lower than design temperature; At this moment closed electromagnetic valve, heat collector gets into the thermal-arrest state again, repeats above-mentioned action again after the enough heat; When run into wet weather or the time rainy day gas when fine, heat collector does not reach design temperature yet in setting-up time, at this moment magnetic valve is opened equally automatically; With having heated in the heat collector but the hot water that does not reach design temperature is expressed into heat release in the heat storage box, the heat-storage medium temperature in heat storage box be reduced to air can the constant temperature start-up temperature, at this moment air can start and heats; Magnetic valve cuts out simultaneously, and heat collector gets into cold water efficient heat-collecting state again, and air can be in the process of heating; If heat-collecting temperature reaches design temperature, magnetic valve is opened equally hot water is clamp-oned heat release heating heat-storage medium in the heat storage box, reaches design temperature until water tank temperature; Air can be shut down, and system gets back to the thermal-arrest time status again, comes to this; System moves according to Changes in weather automatically, and the collecting efficiency of system is greatly improved when making winter, adds the integrated use of air ability; It is equally very energy-conservation that system had both reached winter, and can not make the effect of heat-storage medium temperature superelevation summer again, ensured again in the time of efficient energy-saving that system stability is durable.Because air can adopt round-the-clock because of need working at any time, rather than regularly detects the control of the work that gets into again, so, effectively reduced the number of configured that air can unit, reduced the input at system's initial stage, accelerated investment payback period.

The utility model inner disk is put SUS304 food-grade stainless steel ripple heat exchange coil, and the ripple heat exchange coil is handled through high-temperature technology, though wall thickness only has 0.25mm; Bearing capacity but reaches 16Mpa, and bearing capacity is far longer than tap water pressure when having guaranteed the heat transfer rate, guarantees that product stablizes durable; The water or other heat-storage medium that store in the heat storage box are only made the heat accumulation media, do not use, when needs use hot water; Cold water process in the stainless steel ripple heat exchange coil of pressure-bearing fully absorbs the heat of heat accumulation media, thereby reaches the effect of physics heat exchange; The hot water instant heating i.e. usefulness, and the fresh health of water quality has thoroughly been stopped the phenomenon of water pollution once again.Stainless steel ripple heat exchange coil cooling water inlet is equipped with the pure water device, and cold water just gets in the ripple heat exchange coil after being filtered into pure water and absorbs heat, and becomes the fresh pure hot water that can directly drink, has solved the technical barrier that hot water is difficult to filter at once.The utility model has improved the quality of using in each water field greatly, cooperates clear energy sources products such as solar energy, air ability to use, and is in the pink of condition energy-conservation.
