The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with concrete accompanying drawing, realization of the present utility model is described in detail.
As shown in Figure 1, the preferred embodiment provided for the utility model.
The Split heat pump hot water machine that the present embodiment provides, comprise water tank 5, main frame 1 and refrigerant pipeline, and described refrigerant pipeline connects described water tank 5 and main frame 1, forms a refrigerant circulation circuit, in this refrigerant circulation circuit, is filled with heat transferring medium.Described refrigerant pipeline comprises that refrigerant inlet pipe 81 and refrigerant go out pipe 82, described refrigerant inlet pipe 81 guiding heat transferring mediums are flowed back in described main frame 1 by described water tank 5, described refrigerant goes out the described heat transferring medium of pipe 82 guiding and flows to described water tank 5 by described main frame 1 is interior, described refrigerant inlet pipe 81 is provided with a temperature sensor 7, this temperature sensor 7 for detection of in refrigerant inlet pipe 81 in the temperature of the interior heat transferring medium after heat exchange of water tank 5.According to the exchange heat principle of mobile equilibrium, convert and can obtain the mean temperature of whole water tank 5 interior waters by certain formula, when the controller of system receives that mean temperature that temperature sensor 7 detects reaches the water temperature of setting, just sending signal controlling compressor 3 shuts down, when the controller of system is received mean temperature that temperature sensor 7 detects lower than the water temperature set, just send 3 continuous runnings of signal enabling compressor, so, avoiding arranging a plurality of holes and blind pipe on water tank 5 installs heat detector and detects the water temperature in water tank 5, not only the magnitude setting of temperature sensor reduces, structure is simplified, install more convenient, also reduced the risk that water tank 5 leaks simultaneously, guaranteed the reliability that Split type hot water is used, in addition, this design also makes the control of Hot water units more accurate.
Particularly, described main frame 1 comprises compressor 3 and heat exchanger 2, the air entry of described compressor 3 connects the first port of described heat exchanger 2 by a pipeline, the exhaust outlet of described compressor 3 connects described refrigerant and goes out pipe 81, and the second port of described heat exchanger 2 connects described refrigerant inlet pipe 82.Particularly, described heat exchanger 2 mainly is comprised of an evaporimeter 22 and a blower fan 21.The heat transferring medium that flows into evaporimeter 22 absorbs the heat of outside air by evaporimeter 22, blower fan 21 takes away the air turned cold in time, accelerates Air Flow.Heat transferring medium flows in compressor 3 after heat exchanger 2 is tentatively heated, and compressor 3, by the compression heat transferring medium, further heats up heat transferring medium, then goes out pipe 82 by refrigerant and guide in water tank 5, to the heating of the water in water tank 5.
Further, on described refrigerant inlet pipe 81, between described temperature sensor 7 and described heat exchanger 2, be provided with throttle part 6.Control the flow of heat transferring medium by this throttle part 6 is set, reduced the loss of heat energy, improve the rate of heat exchange of heat transferring medium.When described compressor 3 shuts down, described throttle part 6 is closed fully, prevents the internals of heat transferring medium impingement heat transfer device 2 and by its damage.During concrete enforcement, described throttle part 6 can be electric expansion valve, heating power expansion valve or capillary, but select electric expansion valve, is good, to realize the accurate adjusting to the heating capacity of system, the refrigerant inlet pipe can be closed in case of necessity simultaneously.
Further, the exhaust ports of described compressor 3 also is provided with check valve 4.Like this, can prevent the heat transferring medium adverse current, when described compressor 3 shuts down, avoid heat transferring medium to impact the internals of described compressor 3 and cause damage.
Further, described main frame 1 also comprises housing 11, and described housing 11 has cavity 12, and described compressor 3, check valve 4, throttle part 6 and heat exchanger 2, temperature sensor 7 all are arranged in described cavity.Like this, temperature sensor 7 is positioned at described main frame 1.Like this, the length specification of the connecting line of temperature sensor 7 is certain, can in factory, unify to install fixing, so, the workman field erected workload reduced, simultaneously, be not subject to the distance limit between described water tank 5 and main frame 1, simplified installation, improved the stability that Teat pump boiler is used.In addition, by housing 11, form an overcoat, prevent the pollution corrosion of external environment to the main frame inner part.
Further, described water tank 5 comprises inner bag 54 and is located at the heat(ing) coil 53 in described inner bag 54; There is water inlet 55 and delivery port 51 on described inner bag 54; Cold water is flowed into by described water inlet 55, and hot water is flowed out by described delivery port 51; The arrival end of described heat(ing) coil 53 connects described refrigerant and goes out pipe 82, and the port of export of described heat(ing) coil 53 connects described refrigerant inlet pipe 81.In use, described heat(ing) coil 53 mostly is spiral coil or serpentine coil, thereby strengthens the heat exchange area of described heat(ing) coil 53, improves its heat exchange efficiency.
Further, described water inlet 55 is located at the bottom of described inner bag 54, and described delivery port 51 is located at the top of described inner bag 54.Usually, the entrance of described heat(ing) coil 53 is arranged at the upper end of described water tank 5, and outlet is arranged at the lower end of described heat(ing) coil 53.Heat transferring medium enters described heat(ing) coil 53 when interior, temperature is the highest, flow from top to bottom, the TNE UPPER SEA TEMPERATURE of water tank 5 is higher than lower floor water temperature, when heat transferring medium is flowed through water tank 5 upper strata, have a narrow range of temperature, the heat exchange amount is little, all the time the water temperature that guarantees water tank 5 upper stratas is the state in a setting all the time, simultaneously, the constantly water of feed-tank 5 lower floors heating again, until after described heat transferring medium flows out described heat(ing) coil 53, when the temperature of the heat transferring medium detected reaches design temperature, think that heat exchange does not occur the water in heat transferring medium and described water tank 5 substantially, namely the temperature of whole water tank 5 has all arrived design temperature.So, can guarantee the water temperature value of water tank 5 exit hot water, guarantee the comfort level that the user uses.
For reducing the thermal losses of described heat transferring medium, the periphery that described refrigerant inlet pipe 81 and refrigerant go out pipe 82 also is coated with heat-insulation layer (the not shown in the figures meaning out).The periphery of described inner water tank also is enclosed with a heat-insulation layer, slackens inner bag and extraneous heat transfer rate, makes the hot water in water tank to be incubated the longer time, to meet preferably user's user demand.Particularly, described heat-insulation layer 52 be take and selected foaming layer as good, can certainly be other insulation material.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
