The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.
The invention provides a kind of Teat pump boiler that can under utmost point low temperature environment, start fast.
As shown in Figure 1, water heater of the present invention comprises compressor 1, finned cooler 2, condenser fan 21, choke valve 3, finned evaporator 4, evaporator fan 41 and vapour liquid separator 7.Between the entrance of the outlet of compressor 1 and condenser 2, be provided with hot water heat exchanger 5.This hot water heat exchanger 5 is connected with compressor 1 respectively at condenser 2 with the second magnetic valve S2 by the first magnetic valve S1.
The whole operation principle of Teat pump boiler of the present invention is: compressor 1 is compression refrigerant at first, and the vapour-liquid two-phase that produces high pressure is mixed refrigerant, and this mixing refrigerant is discharged from the outlet of compressor 1.The first magnetic valve S1 is connected with a micro controller unit 6 with the second magnetic valve S2, and this micro controller unit 6 heating load is as required regulated the aperture of the first magnetic valve S1 and the second magnetic valve S2 automatically, thereby automatically controls heating load.
Mix refrigerant respectively through behind the second magnetic valve S2, the first magnetic valve S1, enter into condenser 2 and carry out the refrigerant that condensing heat-exchange obtains high-pressure liquid.Then this high-pressure liquid refrigerant carries out the refrigerant that throttling forms low pressure by choke valve 3, and last, these low pressure refrigerant enter evaporimeter 4 and carry out evaporation and heat-exchange, and liquid refrigerant becomes the gaseous coolant of low pressure.The entrance that these vapour-liquid refrigerants enter compressor 1 at last again carries out compression cycle next time.
Because the effect of the first magnetic valve S1 and the second magnetic valve S2, the user can adjust heating load very easily, the double action of automatic equalization heat supply and air-conditioning, and energy-saving effect is obvious.
When outdoor environment temperature was very low, difficulty can occur in compressor start.Owing to storing a large amount of low-temperature refrigerants in the vapour liquid separator 7, so that initial start stage does not have enough gaseous refrigerants to enter into the entrance of compressor.Can start electric heater P2 and come the cold-producing medium in the vapour liquid separator 7 is heated this moment.Perhaps, start bypass heat exchanger P1, open simultaneously entrance control valve S1 and discharge control valve S2.After after normal after system starts, close again entrance control valve S1 and discharge control valve S2.
Below only with an embodiment mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to simultaneously external more functional module, thereby expands to greatest extent its function.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.
