Description
Technical field:
The present invention relates to a kind of water storage device of air-source heat pump hot water group, particularly relate to a kind of small-capacity water tank of air source heat pump water heating units.
Background technology:
Mostly existing air-source heat pump hot water group is to be made up of compressor, air side heat exchanger, blower fan, water-side heat, restricting element, intelligence control system and corresponding water system, its operation principle is that cold-producing medium evaporates the airborne heat of absorption in air side heat exchanger, compressed machine compression back condensation heat release in water-side heat, the heat that absorbs is discharged in the water system, provide the domestic hot-water to the user, this water mode COP value that heats is high, energy-conserving and environment-protective, and overall economic efficiency is good.
Existing storage tank is the pressure-bearing type structure, the cost height, and interface is many, the pipeline complexity.In addition, the storage tank temperature fluctuation is big, has reduced the dischargeable capacity of water tank, the comfortableness that influence is used.The water storage process of circulation heated type is: moisturizing is directly in water tank, make water temperature reach instructions for use gradually through unit circulation heating again, when this just causes unit just to open, the water tank water temperature is very low, along with the operation water temperature of unit raises gradually, reach setting value up to water temperature, thereby the stand-by period is longer, in addition, in use be the guaranteed water level requirement, cold water is directly mended water tank and is mixed with high-temperature water in the water tank, the water tank water temperature is descended, finally can not use, reduce the dischargeable capacity of water tank, the comfortableness that influence is used.
What directly-heated type water storage process adopted is that cold water advances the water supplementing method that hot water goes out, it is exactly that high-temperature-hot-water directly arrives attemperater that cold water comes out through unit, so there is not circulating above-mentioned drawback, and under identical leaving water temperature, the condensation temperature of unit is low, efficient is higher, but this mode also has its inadequate natural endowment:
1, the circulation heated type is still adopted in the insulation of storage tank, and the water tank water storage is temperature limited as previously mentioned.
Under 2 low in the winter time ring environment temperature, the low water temperature condition, very little through the discharge of unit because the decay of the heating capacity of unit is bigger for obtaining high water temperature, do not satisfy instructions for use, therefore must be equipped with bigger storage tank shifts to an earlier date water storage.
3, because discharge is little, degree of regulation to flow control valve has proposed requirements at the higher level, machine can not reach stable duty at short notice, in the start-up course, for avoiding machine pressure excessive, the discharge amplitude of accommodation is big, add the heat loss of cold machine, can sneak into a large amount of cold water in the water tank, influence follow-up water storage process, even water temperature does not also reach instructions for use when water tank system full water.
For satisfying instructions for use, above-mentioned dual mode all needs to be equipped with large water tank, and the drawback that large water tank brings is: 1, cost height; 2, installing space is limited; 3, the water tank volume is big, and leakage heat is many, the energy consumption for keeping temperature height; 4, adopt unit circulation heat tracing, the water tank water storage is temperature limited.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of small-capacity water tank of air source heat pump water heating units, satisfying under the prerequisite that the user makes water consumption, reduced compact water storage tank, it is few to leak heat, and energy consumption for keeping temperature is low; Cabinet insulation adopts the small-power heating tape to be incubated immediately, and the water storage temperature is not limited.
Technical solution problem of the present invention adopts following technical scheme:
Small-capacity water tank of air source heat pump water heating units, described storage tank has into water water inlet interface, water outlet interface, recirculated water interface and inner water tank, between inner water tank and tank shell, be provided with heat-insulation layer, it is characterized in that, outer wall at described heat-insulation layer inner close fitting inner water tank is provided with insulation heating tape, the startup of described insulation heating tape/close by the water temperature in the water tank and control.
Be provided with in the described storage tank and the corresponding to temperature-sensitive pipe of storage tank inner chamber height, the airtight temperature-sensing probe of being close to tube wall that is provided with in the temperature-sensitive pipe, described temperature-sensing probe and controller and insulation heating tape form one can control the control loop that the insulation heating tape starts/closes.
Described storage tank also is provided with can be with storage tank inner chamber and the extraneous breather pipe that communicates.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention is by being provided with the insulation heating tape in storage tank, guarantee that the water temperature in the storage tank does not descend and wasted work province, specifically, the existing large water tank insulation unit circulation heat tracing technology that adopt more, since compressor can not frequent starting characteristic, water tank temperature generally descends and just restarts compressor about 5 ℃, and will move about 7 minutes continuously, thereby cause fluctuating temperature big, big energy-consuming; Because of the characteristic of freon refrigeration system, the water storage temperature can not be above 55 ℃ simultaneously.The present invention's electricity is incubated the startup of heating tape and closes the water temperature that is subjected in the storage tank and control, when recording water temperature, temperature-sensing probe is lower than when setting value, control by controller starts the insulation heating tape, so that the water temperature in the storage tank satisfies water demand, can make the storage tank miniaturization of heat-pump hot-water unit, advantage is: 1, cost is low, and is good in economic efficiency; 2, the water tank volume reduces, and for split type unit, saves indoor installing space, for the monoblock type unit, alleviates main frame weight; 3, the leakage heat loss is little, and use cost is low.
