Abstract
The utility model provides an instant heating type heat pump heater in multi-level serial connection, which is wide in environmental temperature adaptation range, usable for all seasons and capable of controlling heat output. The instant heating type heat pump heater in multi-level series comprises at least two groups of independent steam compression type heat pump devices, each group of steam compression type heat pump device is formed by a compressor, a condenser, a throttling element and an evaporator which are in end-to-end communication through a pipeline, and the condensers of the steam compression type heat pump devices are sequentially and serially connected and communicated by the aid of tap water pipelines. The instant heating type heat pump heater in multi-level serial connection is simple in structure, and low-temperature adaptation and low-temperature heating performance of an air source heat pump heater are effectively improved.
Description
Technical field
The utility model relates to a kind of Teat pump boiler, particularly a kind of plural serial stage instant heating type heat pump water heater.
Background technology
In the Teat pump boiler of many forms, air source hot pump water heater is widely used in China Yangtze river basin, southwest and south China with its distinct advantages, but is restricted in the process of promoting northwards.When temperature descended, evaporating pressure decreased low temperature environment down, thereby the heat pump fluid inspiratory volume is increased, and the unit displacement reduces, and causes heating capacity to decay significantly, is difficult to meet consumers' demand.And along with the reduction of outdoor environment temperature, the pressure ratio of compressor increases, and the substantial deviation optimal value causes the normal compression process of compression process substantial deviation, and reliability of system operation is reduced.In addition, as press worst cold case design source pump, then when environment temperature is higher because of the source pump heating capacity makes the source pump frequent start-stop much larger than the hot water load, reduce the heating performance of unit.Therefore, improve air source hot pump water heater low temperature adaptability, improve its low-temperature heating performance, become important research project in recent years.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of to environment temperature wide accommodation, the four seasons can with and the plural serial stage instant heating type heat pump water heater that can carry out heating capacity output control.
For achieving the above object, the utility model is taked following technical scheme:
The plural serial stage instant heating type heat pump water heater comprises independently vapor compression heat pump device of at least two groups, and each is organized the vapor compression heat pump device and forms through pipeline head and the tail connection successively by compressor, condenser, restricting element, evaporimeter; Each is organized the condenser of vapor compression heat pump device and connects successively, and tap water pipe line is communicated with each condenser successively.
At least one blower fan of evaporimeter arranged outside of above-mentioned heat pump assembly.
Also be provided with electrical auxiliary heater, tap water pipe line is communicated with electrical auxiliary heater through behind each condenser, is communicated with the hot water end again.
The above-mentioned heat pump assembly independence separately of respectively organizing, under the effect of blower fan, evaporimeter absorbs heat with evaporation working medium from surrounding environment; Refrigerant vapor gets into condenser after compressor compresses; To running water release heat and the condensation flow through, by throttling, the pressure and temperature of working medium all reduces when passing through restricting element subsequently in condenser; Turn back to evaporimeter then; So move in circles, running water flows into electrical auxiliary heater after when flowing through condenser, having absorbed the working medium heat, flow to the terminal user of confession of hot water at last and uses.The utility model can be opened one group or the water of the many groups of unlatching heat pump assembly heat production in next life simultaneously separately according to environment temperature, comes the regulating and controlling heat pump heating capacity with this, when the heat pump heating capacity does not reach user's request, can also start electrical auxiliary heater and continue heating.
The utility model is simple in structure, to the environment temperature wide accommodation, has improved the low temperature adaptability and the low-temperature heating performance of air source hot pump water heater effectively.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further.
As shown in Figure 1; The plural serial stage instant heating type heat pump water heater; Comprise two groups of vapor compression heat pump devices and an electrical auxiliary heater 7; These two groups of vapor compression heat pump devices all are made up of compressor, condenser, restricting element, evaporimeter and blower fan, and the outlet of the compressor 1 of first group of heat pump assembly is through the inlet of pipeline connection condenser 2, and the outlet of condenser 2 links to each other with the inlet of restricting element 3 through pipeline; The outlet of restricting element 3 links to each other with the inlet of evaporimeter 4 through pipeline, and the outlet of evaporimeter 4 links to each other with the inlet of compressor 1 through pipeline; The compressor 1 of second group of heat pump assembly ', condenser 2 ', restricting element 3 ' and evaporimeter 4 ' between pipeline connect identical with first group of heat pump assembly.Condenser 2 and condenser 2 ' to connect, blower fan 5 is arranged on the outside of evaporimeter 4.
As shown in Figure 1, be example with first group of vapor compression heat pump device, its running is following: under the effect of blower fan 5; Evaporimeter 4 absorbs heat with evaporation working medium from surrounding environment, and refrigerant vapor is through compressor 1 compression back entering condenser 2, in condenser 2 to the running water release heat and the condensation of the tap water pipe line 8 of flowing through; When passing through restricting element 3 subsequently by throttling; The pressure and temperature of working medium all reduces, and turns back to evaporimeter 4 then, so moves in circles.Running water by the road 8 ductwork pressure (or pump) effect flow through successively down condenser 2 and condenser 2 ', and with the heat pump fluid heat exchange after flow into electrical auxiliary heater 7, flow to hot water terminal 6 at last and supply users' uses.If the heat pump heating capacity reaches user's request, then electrical auxiliary heater 7 is stopped using, otherwise electrical auxiliary heater 7 brings into operation.
Above-mentioned description to embodiment is to be convenient to the understanding of the those of ordinary skill of this technical field and to use the utility model.Those of ordinary skill in the art obviously can easily make various modifications to embodiment, and among the embodiment that is applied to other in the General Principle of this explanation and needn't pass through performing creative labour.Therefore, the utility model is not limited to the foregoing description, and those skilled in the art are according to the content of above announcement, the improvement of having done under the situation that does not break away from the utility model category and revise all should protection domain at the utility model within.
