The specific embodiment
As shown in Figure 1, this solar heat-pump water heater mainly comprises water tank 11, solar thermal collector 1, evaporimeter 4, compressor 9, condenser 12.Water tank 11 is a press-bearing water tank, and condenser 12 places in the water tank 11.Solar thermal collector 1 adopts U type pipe pressure-bearing type solar heat collector, is convenient to combine with architecture-integral.
Gas outlet first magnetic valve 5 of evaporimeter 4, four-way change-over valve 10 connect the air inlet of compressor 9.The gas outlet of solar thermal collector 1 is communicated with compressor 9 air inlets by second magnetic valve 7, pressure-reducing valve 6, four-way change-over valve 10.The pipeline that the solar thermal collector gas outlet is communicated with is provided with expansion drum 3.The gas outlet of compressor 9 connects the air inlet of condenser 12 through four-way change-over valve 10.Solar thermal collector 1 gas outlet the 3rd magnetic valve 8 connects the air inlet of condenser 12.The outlet of condenser 12 connects the inlet of evaporimeter 4 through the 4th magnetic valve 14, drier 20, filter 21, first capillary 13, filter 22.The outlet of condenser 12 connects the inlet of solar thermal collector 1 through the 5th magnetic valve 15, drier 17, filter 18, second capillary 16, filter 19.
Solar thermal collector 1 is provided with the solar energy photocell board 2 that detects solar illuminating intensity.Temperature sensor 71,72,73 is separately positioned in the exit, evaporimeter 4 exits, water tank 11 of solar thermal collector 1. Temperature sensor 71,72,73 and solar energy photocell board 2 all are electrically connected with the input of master controller; Master controller connection and control compressor 9 switches and first magnetic valve 5, second magnetic valve 7, the 3rd magnetic valve 8, the 4th magnetic valve 14, the 5th magnetic valve 15.
During work, detect solar irradiation intensity, be input to master controller, by the strong and weak preliminary judgement solar irradiation intensity of sensed current signal with current signal by solar energy photocell board 2.Select mode of operation according to detected water tank water temperature, solar thermal collector outlet temperature, evaporator outlet temperature then.Its mode of operation is divided into Natural Circulation, solar heat pump circulation, solar energy+evaporator heat pump circulation, evaporator heat pump independent loops.
Natural Circulation: big when judging solar irradiation intensity by the electric current power that detects solar energy photocell board 2, and temperature sensor 71 detects the solar thermal collector outlet temperature, and judge by master controller and to reach cold-producing medium working medium evaporating temperature, then the 3rd magnetic valve 8 is opened, and system enters natural circulation mode.This moment, solar thermal collector 1 absorption heat heated cold-producing medium working medium wherein, and cold-producing medium working medium arrives condensers 12 by the 3rd magnetic valve 8, heat release in water tank, thus be used for producing hot water.Cold-producing medium working medium after the heat exchange is back in the solar thermal collector through the 5th magnetic valve 15, second capillary 16 from condenser, finishes a working cycles.Circulate so repeatedly until the heating whole box water.In this cyclic process, main controller controls first magnetic valve 5, second magnetic valve 7, the 4th magnetic valve 14 are closed, and compressor 9 is shut down.This mode of operation not power consumption fully.
Solar heat pump circulation: when solar irradiation intensity diminishes and the solar thermal collector outlet temperature reduces by judging, in the time of can't adopting Natural Circulation to produce hot water, then system enters the solar heat pump endless form., absorb energy by solar thermal collector 1 as evaporimeter with solar thermal collector 1, heating cold-producing medium working medium wherein enters compressor 9 through second magnetic valve 7, pressure-reducing valve 6, four-way change-over valve 10 then.This moment, compressor was in open state, and compressed machine 9 consumed powers acting becomes high-temperature high-pressure refrigerant gas with cold-producing medium working medium, and then enters condenser 12 through four-way change-over valve 10, heat release in water tank 11.Cold-producing medium the 5th magnetic valve 15 after the heat exchange, become normal temperature and pressure cold-producing medium working medium through second capillary 16 and get back to solar thermal collector 1, finish a working cycles, produce the hot water purpose until reaching by circulating so repeatedly.In this cyclic process, main controller controls first magnetic valve 5, the 3rd magnetic valve 8, the 4th magnetic valve 14 are closed.This mode of operation power consumption seldom.
Solar energy+evaporator heat pump circulation: when solar irradiation intensity and solar thermal collector outlet temperature continuation reduction, system enters this circulation pattern.This moment, solar thermal collector 1 all was equivalent to evaporimeter with evaporimeter 4, and both absorb heat simultaneously cold-producing medium working medium is heated to be gaseous state.Because the solar thermal collector endothermic effect is good, therefore before the cold-producing medium working medium that the cold-producing medium working medium and the evaporimeter 4 of solar thermal collector 1 output are exported is converged, cold-producing medium working medium with solar thermal collector 1 output reduces pressure earlier, make its pressure similar to the pressure of evaporimeter 4 outputs, reach common pressure and be sent to compressor 9, pressure-reducing valve 6 plays this depressurization.Compressor is in open state, is converted to high-temperature high-pressure refrigerant gas after the compressed machine 9 power consumptions acting, enters condenser, after water heat exchange lifting water temperature in the water tank, is converted into the refrigerant gas of cryogenic high pressure.A part becomes the low-temp low-pressure liquid refrigerant and comes back to evaporimeter 4 after the 4th magnetic valve 14,13 throttlings of first capillary then, and another part is got back in the solar thermal collector 1 through the 5th magnetic valve 15, second capillary 16, finishes a working cycles.So repeatedly, whole box water can be heated.In this cyclic process, the 3rd magnetic valve 8 cuts out.The power consumption of this mode of operation is big than the power consumption of solar heat pump circulation pattern.
The evaporator heat pump circulation: when the no solar irradiation of detection, when the heat collector outlet temperature is minimum, then system enters the evaporator heat pump circulation pattern.At this moment, utilize the evaporimeter 4 heating and cooling agent working medium that absorbs energy, enter compressor 9 imports through first magnetic valve 5, four-way change-over valve 10 then, compressor is in open state, and compressed machine 9 power consumptions acting becomes high-temperature high-pressure refrigerant gas with cold-producing medium working medium.Enter condenser 12 through four-way change-over valve 10 then, in water tank 11 after the heat release, become normal temperature and pressure cold-producing medium working medium and get back to evaporimeter 4 through the 4th magnetic valve 14, first capillary 13, finish a working cycles, circulation can realize producing the purpose of hot water and so forth.In this cyclic process, second magnetic valve 7, the 3rd magnetic valve 8, the 5th magnetic valve 15 are closed.This mode of operation is than the power consumption maximum of other three kinds of mode of operations.
All the other do not state technology is known technology.
