Description
Technical field
The present invention relates to heat-pump water heater, more particularly, relate to a kind of store heat at a lower temperature and when the user uses, can satisfy the water circulating heat pump hot water apparatus of instant-heating pattern.
Background technology
At present, air source hot pump water heater mainly is to utilize the attemperater store heat, is about to water and is heated to above the temperature (as 55 ℃) that the user needs and stores, and needs in order to the user.There are problems in such method of operation: the one, and inevitably there is dissipation loss in hot water; The 2nd, the high temperature that heats reduces the efficient of heat pump assembly, and functional reliability reduces; The 3rd, than under the low ambient temperature, the heat capacity of its device is lower, is difficult to satisfy user's needs.To above problem, can design a kind of radiation loss less, instant-heating, and efficient more and reliable, the stronger Teat pump boiler of low-temperature working ability becomes the problem that presses for solution simultaneously.
Summary of the invention
The object of the present invention is to provide and a kind ofly can prolong working life, improve the thermal efficiency of device and water circulating heat pump hot water apparatus that can instant-heating.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of water circulating heat pump hot water apparatus, it comprises the heat pump structure, this heat pump structure comprises that compressor, condenser, flow controller, evaporimeter and above-mentioned compressor, condenser, flow controller, evaporimeter are communicated with into enclosed construction successively through pipeline; It also comprises cold water storage cistern and middle reservoir; Said cold water storage cistern is communicated with said middle reservoir through pipeline, water valve earlier; Reservoir is communicated with condenser, evaporimeter respectively through pipeline again in said; And said evaporimeter also is connected to form a water circulation structure of being made up of cold water storage cistern, middle reservoir, evaporimeter through pipeline and said cold water storage cistern; On said condenser, be provided with hot water outlet.
The present invention is owing to having adopted said structure, so it has following beneficial effect:
In the present invention, the moisture of middle reservoir is two supplies, and one the road flows into condenser and another road inflow evaporator.The water that middle reservoir is supplied with is that evaporimeter provides heat, and the water of evaporimeter flows back to cold water storage cistern again and reheated after reducing temperature; The water that middle reservoir is supplied with obtains heat in condenser, when being increased to user's design temperature, can supply the user to use, so the present invention does not need the attemperater stored hot water, it can directly be supplied with the user and use, and is the instant-heating type.Because the water through heating can directly be used by the user, promptly directly is heated to suitable temperature at use side and can supplies the user to use, so the temperature that heats of the present invention greatly reduces; According to thermodynamic (al) law of correlation; Heat the reduction of temperature, will improve the efficient of heat pump cycle, improve its working condition simultaneously; Reduce the delivery temperature and the pressure of compressor, prolong working life; Because the temperature of device thermal energy storage reduces, thereby dwindled the temperature difference with environment, reduced the radiation loss of device, thereby improved the thermal efficiency of device; Because other mode of heatings have higher efficient and ability when the water of heating lower temperature in the winter time; Like air source heat pump; When the hot water of producing 20 ℃-30 ℃, better performance is arranged, also make device stronger to the adaptive capacity of low temperature, winter, service behaviour increased substantially.
After the detailed description that combines advantages embodiment of the present invention, it is clearer that characteristics of the present invention and advantage will become.
Description of drawings
Fig. 1 is a block diagram of the present invention.
Among the figure: 100. heat pump structures, 1. compressor, 2. condenser, 3. choke valve, 4. evaporimeter, 5. in reservoir, 6. hot water outlet, 7. cold water storage cistern, 8. water valve.
The specific embodiment
With an embodiment the present invention is done further detailed explanation below, but should explain that protection scope of the present invention is not limited only to this.
Consult Fig. 1; A kind of water circulating heat pump hot water apparatus; It comprises heat pump structure 100, and this heat pump structure 100 comprises that compressor 1, condenser 2, flow controller 3, evaporimeter 4 and above-mentioned compressor 1, condenser 2, flow controller 3, evaporimeter 4 are communicated with into enclosed construction successively through pipeline; It also comprises cold water storage cistern 7 and middle reservoir 5; Said cold water storage cistern 7 is communicated with said middle reservoir 5 through pipeline, water valve 8 earlier; Reservoir 5 is communicated with condenser 2, evaporimeter 4 respectively through pipeline again in said; And said evaporimeter 4 also is connected to form a water circulation structure of being made up of cold water storage cistern 7, middle reservoir 5, evaporimeter 4 through pipeline and said cold water storage cistern 7; On said condenser 2, be provided with hot water outlet 6.
During the work of this embodiment, compressor 1 starts operation, and the moisture that is supplied to come by middle reservoir 5 is two-way; One the road flows into condenser 2 and another road inflow evaporator 4, and then, the hot water that heats through condenser 2 supplies users to use by hot water outlet 6 outflows; And; Again after device provides heat, after the water Returning water case that after reducing temperature, flows out evaporimeter 4 reheated middle temperature, reservoir 5 was subsequent use in water valve 8 flows into again through the water of evaporator 4.In reservoir 5 and cold water 7 by similar approach, through water pipe line can be in a plurality of heat-pump water heaters supplies warm water, and reclaim cold water.Each heat-pump water heater is all worked with the instant-heating mode, when the user does not use hot water, shuts down.
In this embodiment, the water source of temperature during the device of this embodiment needs, as 20 ℃-30 ℃, its heat can be provided by modes such as solar energy, underground water, air source heat pump, waste heats.In this embodiment, be a small-sized water resource heat pump in the essence of user side unit, be that with a big key difference of conventional water resource heat pump condenser of this device and the required water of evaporimeter are from same water source, promptly from the supply of middle reservoir 5.
The heating capacity of the device of this embodiment and weather are irrelevant; The supply water temperature of warm water is suitable in only requiring can prepare hot water endlessly; And in cold season that needs most heat and area, the ability of warm water was stronger during various energy-conservation mode of heatings provided, simultaneously; For middle warm water insulation also is more prone to easy, heat loss is littler.
Though described embodiment of the present invention in conjunction with accompanying drawing; But those skilled in the art can make various distortion or modification within the scope of the appended claims; As long as be no more than the described protection domain of claim of the present invention, all should be within protection scope of the present invention.
