Abstract
A heat pump water heater with phase-transition heat storage water tank comprises a compressor, a condenser, a heat storage element, a water tank, a restricting element, an evaporator and a fan. The main technical characteristic of the heat pump water heater is that: the heat storage element is arranged in the water tank to form a phase-transition heat storage area. The utility model has the advantages of effectively improving the heat storage capacity of the water tank, improving the temperature characteristic of the water tank, simplifying the structure of the heat pump water heater and facilitating maintenance of the heat storage element, etc.
Description
Technical field:
The utility model relates to a kind of Teat pump boiler, particularly a kind of Teat pump boiler with the phase-transition heat-storage water tank.
Background technology:
At present, known Teat pump boiler supporting water tank, water is as heat storage medium, heat-retaining capacity density is less, causes the volume and weight of water tank bigger.And some adopt the heat pump assembly of heat storage technology, and thermal storage member and heat exchanger integrated design constitute heat regenerator, and heat-storing material contacts with the heat exchanger member, and versatility is bad, and maintenance is comparatively difficult.For overcoming these defectives, the Teat pump boiler of band phase-transition heat-storage water tank is developed.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of Teat pump boiler with the phase-transition heat-storage water tank, it can improve effectively water tank amount of stored heat, improve water tank temperature characterisitic, simplify Teat pump boiler structure, be convenient to the maintenance of heat accumulating element.
The technical scheme that its technical problem that solves the utility model adopts is:
It comprises compressor, condenser, heat accumulating element, water tank, restricting element, evaporimeter, blower fan, and described heat accumulating element is placed in the water tank, forms the phase-transition heat-storage district.
Described heat accumulating element is placed on high-temperature region in the water tank.
Described heat accumulating element is the different heat accumulating element unit combination of phase transition temperature.
Described heat accumulating element is a separate unit.
The utility model is compared the beneficial effect that is produced with background technology:
1, because adopting, the utility model in water tank, places heat accumulating element, the heat-storing material that employing undergoes phase transition in the relevant temperature scope, heat-storing material is in phase transition process, the heat that absorbs and discharge is bigger, under the constant situation of hot water storage tank appearance and size and gross weight, the water tank amount of stored heat significantly improves; And because the approximate isothermal exothermic character that phase change heat storage material has, leaving water temperature is more stable.
2, since the utility model can several phase transition temperatures are different heat accumulating element mix on demand and be positioned in the water tank, so can obtain the regenerator temperature scope of broad, further improve the temperature characterisitic of water tank.
3, because heat accumulating element has stronger bearing capacity, can directly place press-bearing water tank, thereby simplify the structure of heat pump assembly.
4, adopt the separate unit structure owing to be positioned over the heat accumulating element of water tank, and appearance and size is less,, is convenient to maintenance so can take out one by one by the service ports of water tank.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to accompanying drawing 1, present embodiment comprises compressor 1, condenser 2, heat accumulating element 3, water tank 4, restricting element 5, evaporimeter 6, blower fan 7.The HTHP gaseous working medium that compressor 1 is discharged enters condenser 2, condenser 2 is immersed in the hot water of water tank 4, heat pump fluid liquefies at condenser 2 after enter evaporimeter 6 after restricting element 5 decompressions, blower fan 7 is used for carrying out the air circulation that heat transmits at evaporimeter, heat pump fluid is drawn airborne heats and is vaporized at evaporimeter 6, and gaseous working medium enters the suction end of compressor 1.In hot water storage tank 4, heat accumulating element 3 is placed on the high-temperature area of water tank 4, forms a phase-transition heat-storage district.The process of accumulation of heat is as follows, heat pump fluid is the higher zone of formation temperature around condenser 2, heat transmits to the lower zone of temperature with conduction pattern, when heat accumulating element 2 skin temperatures are higher than the condensing temperature of phase-change material, solid-state heat-storing material heat absorption back liquefaction in the heat accumulating element, reduce heat accumulating element coolant-temperature gage on every side simultaneously, in water tank, form the heat condition of transmitting of heat-accumulating process thus.Exothermic process is as follows, the water that temperature is lower enters water storage box 4 backs by the phase-transition heat-storage district, solidifies after the liquid heat-storing material heat release in the heat accumulating element 3, skims over the heat accumulating element 3 corresponding rising of current temperature on every side simultaneously, become the higher water of temperature gradually, send then.
Nontoxic, heat proof material making that the heat accumulating element 3 that the utility model adopted, shell adopt, inside charges into heat-storing material, and the reliable sealing means sealing of these used for heat-storage material is in the enclosure.Under the Teat pump boiler service condition, heat accumulating element 3 can be not damaged in corresponding temperature, pressure limit.Heat-storing material is nontoxic, non-stimulated to human body, and the structural material of the parts that cisten mechanism material and heat pump water heater hot-water are contacted does not have corrosion, and not volatile.
