The specific embodiment:
Shown in accompanying drawing 1, accompanying drawing 2, present embodiment comprises low-voltage protective switch 1, compressor 2, high voltage protective switch 3, defrosting magnetic valve 4, enclosure 5, combustion gas heat exchanger 6, gas burner 7, the temp probe of falling the cigarette 8, temperature controller 9, gas control valve 10, press-bearing water tank 11, water temperature probe 12, water pump 13, heat exchanger 14, control device 16, evaporator temperature probe 17, heating power expansion valve 18, evaporimeter 19, evaporator fan 20, by-pass line 21.
The arrival end 25 of working medium pipeline 24 is connected with the port of export 22 in the compressor 2 in the auxiliary heating working medium device 15 of combustion gas, and the port of export 26 of working medium pipeline 24 is connected with working medium arrival end 23 in the heat exchanger 14.
Be provided with enclosure 5, combustion gas heat exchanger 6, gas burner 7, the temp probe of falling the cigarette 8, temperature controller 9, gas control valve 10 in the auxiliary heating working medium device 15 of combustion gas, gas control valve 10 is installed on the gas pipeline below the gas burner 7, combustion gas heat exchanger 6 is installed in the top of burner 7, enclosure 5 is installed in the top of combustion gas heat exchanger 6, the temp probe of falling the cigarette 8 is fixed on the enclosure 5, and temperature controller 9 is fixed on the working medium pipeline 24 of combustion gas heat exchanger 6.
Compressor 2, heat exchanger 14, heating power expansion valve 18, evaporimeter 19 connect by pipeline, constitute the working medium circulating line of heat pump, heat exchanger 14, water pump 13, press-bearing water tank 11 connect into water circulating pipe by pipeline successively, and working medium is passed through heat exchanger 14 the water in the heat transferred water circulating pipe.Evaporator fan 20 is fixed on a side of evaporimeter 19; evaporator temperature probe 17 is fixed on the evaporimeter 19; on the inlet pipeline 23 of compressor 2, low-voltage protective switch 1 is installed; on the port of export 22 of compressor 2, high voltage protective switch 3 is installed; the port of export 22 in compressor 2 and combustion gas are assisted between the heating working medium device 15 and are provided with a by-pass line 21 between heating power expansion valve 18 and the evaporimeter 19, and by-pass line 21 is provided with defrosting magnetic valve 4.
Compressor 2, defrosting magnetic valve 4, the temp probe of falling the cigarette 8, temperature controller 9, gas control valve 10, water temperature probe 12, water pump 13, evaporator temperature probe 17, evaporator fan 20 electrically connect with control device 7 respectively.
During work, the water temperatures that control device 16 is popped one's head in the 12 perception press-bearing water tanks 11 by water temperature are lower than setting value, start compressor 2, evaporator fan 20 is started working, working medium becomes the high pressure-temperature gaseous state after by compressor 2, become high-pressure liquid through the water heat exchange in heat exchanger 14 and the press-bearing water tank 11, high-pressure liquid working medium becomes the low-pressure low-temperature liquid state through behind the heating power expansion valve 18, the low-pressure low-temperature liquid refrigerant absorbs the air that is blown by evaporator fan 20 at evaporimeter 19 places heat has become the low pressure gaseous state, 2 compressions become the high pressure-temperature gaseous state again to the low pressure gaseous working medium through compressor, so absorb airborne heat circularly and heat water in the press-bearing water tank 11, the water in the press-bearing water tank 11 are heated to setting value the most at last.When compressor 2 inlet pressures are crossed when low; low-voltage protective switch 1 can be given control device 16 signals, and control device 16 shuts down compressor 2 to signal, when compressor 2 inlet pressures are too high; high voltage protective switch 3 can be given control device 16 signals, and control device 16 shuts down compressor 2 to signal.When evaporator temperature probe 17 perceives evaporimeter 19 frostings, give control device 16 signals, control device 16 opens defrosting magnetic valve 4 to signal, and high temperature refrigerant flows back to evaporimeter 19 by by-pass line 21, and the frost of evaporimeter 19 is dissolved.
The working medium of combustion gas heat exchanger 6 is crossed when low by the evaporator temperature 17 perception ambient air temperatures of popping one's head in, depend merely on working medium draw heat from air this moment, and to add the spent time of hot water long, control device 16 starts the auxiliary heating working medium device 15 of combustion gas, make its unlatching for gas control valve 10 electric currents, gas-flow to gas burner 7 places are lighted, fuel gas buring produces the working medium that high-temperature flue gas heats the combustion gas heat exchanger 6 of flowing through, become low-temperature flue gas after enclosure 5 is discharged through combustion gas heat exchanger 6, heated high temperature refrigerant becomes cryogenic fluid through the water heat exchange of heat exchanger 14 and press-bearing water tank 11, and the water in the press-bearing water tank 11 constantly are heated until reaching setting value.The temp probe of falling the cigarette 8 perceives the too high or temperature controller 9 of flue-gas temperature and perceives the working medium temperature of the combustion gas heat exchanger 6 of flowing through when too high, and control device 16 is shut down water heater, and it is protected, and avoids water heater to be damaged.
