Teat pump boilerTechnical field
The utility model relates to a kind of Teat pump boiler.
Background technology
At present, in Teat pump boiler industry, the storage of heat is all the sensible heat with water, to improve the mode of the temperature of water, carry out heat accumulation, hot water storage in attemperater for user, in order to store enough hot water, heat-pump hot-water apparatus only has by increasing the temperature of volume and the raising water storage of attemperater, so can cause Teat pump boiler volume excessive, and due to the distinctive operating characteristic of heat pump, heating higher temperature can reduce efficiency and the reliability of system.In addition, the attemperater of Teat pump boiler generally adopts bottom delivery port make-up water source, the mode of the outside hot-water supply of water inlet is established at top, therefore unavoidably can cause the mixing of hot and cold water, so can make the water temperature in attemperater constantly reduce, when its temperature is reduced to can not use time, remaining heat has in fact just been wasted.Although each producer is all making great efforts to reduce hot and cold water mixing, in fact, due to the restriction of this heat accumulation mode of sensible heat heat accumulation, its effect is extremely limited.
Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, and a kind of Teat pump boiler is provided, and it cancels the use of attemperater, but can reach the i.e. result of use of use of hot water instant-heating.
Its technical scheme is as follows:
A kind of Teat pump boiler, comprise heat storage box, compressor, condenser, throttling arrangement and evaporimeter, heat storage box inside is provided with memory space, heat storage box also comprises the first heat exchange pipeline and the second heat exchange pipeline, the second heat exchange pipeline is provided with water nozzle and water inlet, condenser comprises the 3rd heat exchange pipeline and the 4th heat exchange pipeline, the first heat exchange pipeline, the 3rd heat exchange pipeline, throttling arrangement, evaporimeter, compressor connect and compose closed circuit successively, the 4th heat exchange pipeline is provided with delivery port and water supplement port, and delivery port is connected with water inlet.
Below further technical scheme is described:
Described heat storage box inwall is also provided with heat-insulation layer.
Described the first heat exchange pipeline and the second heat exchange pipeline are located in memory space.
Wherein, also comprise electric controller and fan, fan and described evaporimeter are suitable, and electric controller and described compressor are electrically connected.
Below the principle of aforementioned techniques scheme, effect etc. are described:
1, cancelled the use of attemperater, the volume of newly-designed heat storage box is much smaller, thereby has reduced widely the volume of water heater, neither affects the heating efficiency of heat pump simultaneously, make again the hot water can plug and play, promoted greatly efficiency and convenience.
2, make dexterously water source carry out heat temperature raising twice, in the 4th heat exchange pipeline, carry out in heat temperature raising and the second heat exchange pipeline, carrying out heat temperature raising for the second time for the first time, hot water instant-heating i.e. stablizing effect and the continuation of use have been guaranteed, so also improved heat energy service efficiency, make compressor avoid frequent starting and exceed ground power output, thereby having improved service life and guaranteed heat stability.

The specific embodiment
Below embodiment of the present utility model is elaborated:
As shown in Figure 1, a kind of Teat pump boiler, comprise heat storage box 10, frequency-changeable compressor 34, condenser 20, throttling arrangement 31 and evaporimeter 32, heat storage box 10 inside are provided with insulating 16 and memory space, in memory space, fill phase-change heat-storage material 15, heat storage box 10 also comprises the first heat exchange pipeline 11 and the first heat exchange pipeline 12, the first heat exchange pipeline 11 and the first heat exchange pipeline 12 are located in memory space, the first heat exchange pipeline 12 is provided with water nozzle 13 and water inlet 14, condenser 20 comprises the 3rd heat exchange pipeline 21 and the 4th heat exchange pipeline 22, the first heat exchange pipeline 11, the 3rd heat exchange pipeline 21, throttling arrangement 31, evaporimeter 32, frequency-changeable compressor 34 connects and composes closed circuit successively, the 4th heat exchange pipeline 22 is provided with delivery port 23 and water supplement port 24, delivery port 23 is connected with water inlet 14, also comprise fan 33 and electric controller, fan 33 is suitable with evaporimeter 32, electric controller and frequency-changeable compressor 34 are electrically connected.
Teat pump boiler in use, the first heat exchange pipeline 11, the 3rd heat exchange pipeline 21, throttling arrangement 31, evaporimeter 32, frequency-changeable compressor 34 have connected and composed the heat pump of closed circuit successively, frequency-changeable compressor 34 starts, fan 33 starts, make the heat in heat pump absorbing environmental, afterwards, heat pump is the phase-change heat-storage material 15 heat supplies intensification that makes it to be heated by the first heat exchange pipeline 11 in heat storage box 10, and the 3rd 21 of heat exchange pipelines are the intensification that makes it to be heated of the water extraction heating load in the 4th heat exchange pipeline 22.Therefore, when cold water source enters from water supplement port 24, while flowing through the 4th heat exchange pipeline 22, the heat that first directly sorption type heat pump system provides carries out heat temperature raising, carry out heat temperature raising for the first time, when the first heat exchange pipeline 12 is flowed through by water inlet 14 in water source, phase-change heat-storage material 15 is to the intensification that makes it to be heated of water source transferring heat, be the heat temperature raising for the second time at water source, then by water nozzle 13, flow out for user.
The present embodiment tool has the following advantages:
1, cancelled the use of attemperater, the volume of newly-designed heat storage box 10 is much smaller, thereby has reduced widely the volume of water heater, neither affects the heating efficiency of heat pump simultaneously, make again the hot water can plug and play, promoted greatly efficiency and convenience.
2, make dexterously water source carry out heat temperature raising twice, in the 4th heat exchange pipeline 22, carry out in heat temperature raising and the second heat exchange pipeline 12, carrying out heat temperature raising for the second time for the first time, guaranteed that cool water heating is i.e. stablizing effect and the continuation of use of hot water instant-heating, so also improved heat energy service efficiency, make frequency-changeable compressor 34 avoid frequent starting and exceed ground power output, thereby having improved service life and guaranteed heat stability.
3, in heat storage box 10, be provided with thermal insulation separation thermosphere 16 and fill the phase-change heat-storage material 15 with larger latent heat, guaranteeing that on the one hand heat stores and heat transfer effect, also greatly reduces the volume of heat storage box 10 on the one hand, thereby has reduced the volume of water heater.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
