Description of drawings
Accompanying drawing 1 is the embodiment principle schematic of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: compressor 1, electromagnetism two-port valve 2, water tank heat exchanger 3, throttling arrangement 4, first heat exchanger 5, environment temperature sensor 6, controller 7, electric heater 8.
Shown in accompanying drawing 1, the utility model comprises by compressor 1, electromagnetism two-port valve 2, water tank heat exchanger 3, throttling arrangement 4, first heat exchanger 5, environment temperature sensor 6, controller 7, electric heater 8 and forming; Compressor 1 exhaust outlet is connected with water tank heat exchanger 3 refrigerant inlet; Water tank heat exchanger 3 refrigerant outlets link to each other with throttling arrangement 4 imports; Throttling arrangement 4 outlets are connected to first heat exchanger, 5 refrigerant inlet; 2 imports of electromagnetism two-port valve link to each other with compressor 1 exhaust outlet, and 2 outlets of electromagnetism two-port valve are connected to first heat exchanger, 5 refrigerant inlet.Between first heat exchanger 5 and compressor 1, be provided with electric heater 8, electric heater 8 imports are connected with first heat exchanger, 5 refrigerant outlets, and electric heater 8 outlets link to each other with the return-air mouth of compressor 1.First heat exchanger, 5 bottoms are provided with environment temperature sensor 6.Electromagnetism two-port valve 2 holding wires link to each other with controller 7, and electric heater 8 holding wires are connected to controller 7, and environment temperature sensor 6 holding wires are connected with controller 7.Electric heater 8 adopts electric heating tube commonly used, the model 220V/1000W that the silver-colored city of electric heating tube 8 employings Electrical Appliances Co., Ltd produces.
Normal temperature heating operation pattern: compressor 1 work; Discharge the refrigerant gas of HTHP, high-temperature high-pressure refrigerant gas gets into water tank heat exchanger 3 inside and carries out heat exchange with the water that needs heating, cold-producing medium liquefaction entering throttling arrangement 4 after the heat exchange; After throttling arrangement 4 step-downs, get into first heat exchanger 5; After 5 evaporations of first heat exchanger, become low-pressure gas, low-pressure gas is compressed machine 1 return-air mouth at last and sucks, and has constituted the circulation on fluorine road.At this moment, in the water of the refrigerant gas of the HTHP heat transferred inner water tank that condensation discharged in water tank heat exchanger 3, realize producing the function of hot water.
The low-temperature heating operational mode: under the lower environment of environment temperature, the evaporation efficiency of first heat exchanger 5 is understood step-down, thereby has influenced the normal operation of unit.At this moment, environment temperature sensor 6 can be transferred to controller 7 by the signal that environment temperature is low excessively, and controller 7 control electric heaters 8 are opened; At this moment, the cold-producing medium of the gas-liquid two-phase of the low-temp low-pressure that comes out from first heat exchanger 5 through electric heater 8 heating after, become the gas of high-temperature low-pressure rapidly; Get back to the return-air chamber of compressor 1, continue to heat circulation then, do like this; Not only improve the evaporability of system under the low temperature environment, guaranteed the normal operation of unit, and; Because electric heater 8 is arranged between first heat exchanger 5 and the compressor 1,, avoided the direct contact of supplying water with the user away from the user feed water inlet of water tank heat exchanger; Thereby realized that real user supplies water and the separating of electricity, safety coefficient is high; Environment temperature sensor 6 testing environment temperature have been tending towards normal temperature when detecting environment temperature, will give controller 7 with signal feedback, and controller 7 control electric heaters 8 cut out, and continue operation normal temperature heating operation pattern.
Defrosting mode: in the process that Teat pump boiler heats under low temperature environment; The frosting phenomenon can appear in first heat exchanger 5, and the pipeline temperature of environment temperature sensor 6 during with frosting feeds back to controller 7,2 conductings of controller 7 control electromagnetism two-port valves; The refrigerant gas of the HTHP of compressor 1 discharge this moment will pass through electromagnetism two-port valve 2 and be bypassed to first heat exchanger 5; The refrigerant gas of HTHP flows through from electromagnetism two-port valve 2, directly gets into first heat exchanger 5, discharges heat to first heat exchanger 5; Frost on first heat exchanger 5 will melt away, and reaches the purpose of defrosting.When environment temperature sensor 6 detected temperature reach the defrosting withdraw from design temperature the time, this electromagnetism two-port valve 2 will cut out and continue to heat circulation.
