The specific embodiment

As shown in Figure 1, water heater storage tank 3 is a pressure water tank, the heater inleting pipe's 4 direct and running water upper hose connections on it.Water heater outlet 1 inserts in the water heater storage tank 3, and the upper end of outlet pipe 1 should be on the top of water heater storage tank 3, and the lower end of outlet pipe 1 connects water pipe.Water heater storage tank 3 is the withstand voltage water tanks that have heat-insulation layer, in the bottom of water heater storage tank 3 condenser 22 is housed, and it is to make with metal tube, and import exports in the bottom on top.The high-pressure pipe 27 of condenser 22 connects the C mouth of left four way solenoid valve 5 and the import of condenser 22, the d mouth of left side four way solenoid valve 5 is connected with refrigeration compressor 7 by compressor exhaust pipe 6, refrigeration compressor air inlet pipe 8 is connected with a mouth of left four way solenoid valve 5, the outlet of the b mouth of the left four way solenoid valve 5 of blast pipe 9 connections of evaporimeter and the upper header 13 of evaporimeter, the upper header 13 of evaporimeter and the lower collector pipe 12 of evaporimeter all are that an end is shut other end opening and at the equidistant metal tube of taking over the hole that has of pipe shaft single face, some evaporimeter tubulations 11 are arranged in parallel, and the adapter hole of an end and evaporimeter upper header 13 is connected the adapter hole connection that welds the other end and evaporimeter lower collector pipe 12 and welded.Evaporimeter tubulation 11 is closely linked with evaporimeter tubulation thermal-arrest plate 10, and evaporimeter tubulation thermal-arrest plate 10 is a sheet metal, and its surface is through being treated as the extraordinary black matrix of heat absorption capacity.Collector frame 26 is housed around the heat collector that evaporimeter tubulation thermal-arrest plate 10, evaporimeter tubulation 11, evaporimeter lower collector pipe 12 and evaporimeter upper header 13 are formed, as shown in Figure 2, at the rear portion of evaporimeter foamed polyurethane filler 24 is arranged, can be incubated and prevent that heat from loosing outward.Tempering plated film hollow plate glass 23 is housed in the front portion of evaporimeter, fixes by rubber weather strip 25 between tempering plated film hollow plate glass 23 and the collector frame 26 and seal.One termination evaporimeter lower collector pipe 12 of the air inlet pipe 14 of evaporimeter, the c mouth of the right four way solenoid valve 18 of another termination, the b mouth of right four way solenoid valve 18 is connected by the outlet of condensator outlet pipe 21 with condenser 22.The a mouth of right four way solenoid valve 18 is connected with the import of fluid reservoir 19 by fluid

reservoir inlet tube

15,19 outlets of fluid reservoir outlet 20 1 termination fluid reservoirs, one end of another termination capillary 17, the other end of capillary 17 is connected with the d mouth of right four way solenoid valve 18 by the back low-voltage tube 16 that expands.After whole system connects any leakage must not be arranged, then system be vacuumized and filled a certain amount of refrigeration working medium, seal and to carry out work.On the wall of inner container of the middle part of water heater storage tank 3 temperature sensor 28 is housed, temperature sensor 28 is electrically connected with water heater controller 2 by lead, and water heater controller 2 is electrically connected with left and right four

way solenoid valve

5,18.

When weather is sunny when sunlight is arranged, the b of left and right four

way solenoid valve

5,18, the c mouth communicates respectively, and this moment, water heater was under the heat pipe duty.When solar radiation when being similar to the evaporimeter tubulation thermal-arrest plate 10 of black matrix, it absorbs a large amount of solar energy temperature and rises, it passes to evaporimeter tubulation 11 to heat rapidly, the refrigeration working medium that the evaporimeter tubulation is 11 li is heated, temperature and pressure enters evaporimeter upper header 13 after raising, enter the b mouth of left four-way change-over valve 5 again by the blast pipe 9 of evaporimeter, then from the C mouth of left four-way change-over valve 5 come out the to enter into condenser 22 of water heater storage tank 3 by high condenser pressure air inlet pipe 27, heat is passed to water in the water heater storage tank 3 at 22 li refrigeration working mediums of condenser, refrigeration working medium is condensed into the b mouth that enters right four way solenoid valve 18 behind the liquid under the effect of gravity by condensator outlet pipe 21, come out from the C mouth of right four way solenoid valve 18, be redistributed to evaporimeter tubulation 11 after air inlet pipe 14 by evaporimeter enters evaporimeter lower collector pipe 12, the energy that absorbs the sun again carries out next one circulation.

Not having at the cloudy day can't work under the situation of sunlight heats, when the water temperature that measures when the time water heater temperature sensor of setting to afternoon 28 still is lower than the temperature of setting, water heater controller 2 just can instruct left and right four

way solenoid valve

5,18 to switch, and its a, b mouth are communicated respectively.Though weather does not have visible sunshine, the sun still has the radiant energy of some invisible light wavelengths to pass to the earth.This moment is owing to the radiation that the effect that tempering plated film hollow plate glass 23 and foamed polyurethane filler 24 are arranged makes the evaporimeter tubulation thermal-arrest plate 10 of approximate black matrix between tempering plated film hollow plate glass 23 and the foamed polyurethane filler 24 absorb invisible light wave obtains the thermal source that energy becomes heat pump.On a left side, right four

way solenoid valve

5,18 when switching, refrigeration compressor 7 starts, refrigeration working medium enters the b mouth of left four way solenoid valve 5 by the blast pipe 9 of evaporimeter, a mouth from left four way solenoid valve 5 comes out then, entering refrigeration compressor 7 by refrigeration compressor air inlet pipe 8 compresses, after improving the pressure and temperature of refrigeration working medium, enter the d mouth of left four-way change-over valve 5 by compressor exhaust pipe 6, C mouth from left four-way change-over valve 5 comes out then, enter into condenser 22 by high condenser pressure air inlet pipe 27, heat is passed to water in the water heater storage tank 3 at 22 li refrigeration working mediums of condenser, back refrigeration working medium is condensed into liquid, enter the b mouth of right four way solenoid valve 18 by condensator outlet pipe 21, come out to enter fluid reservoir 19 from a mouth of right four way solenoid valve 18 by fluid reservoir inlet tube 15, liquid refrigeration working medium enters into capillary 17 by fluid reservoir outlet 20 under the effect of pressure, carry out entering the back low-voltage tube 16 that expands after the throttling expansion step-down, d mouth from right four way solenoid valve 18 enters then, C mouth from right four way solenoid valve 18 comes out again, enters evaporimeter tubulation 11 more respectively after the air inlet pipe 14 by evaporimeter enters evaporimeter lower collector pipe 12.Because refrigeration working medium throttling expansion its saturation temperature after the low pressure reduces greatly, so it is in evaporimeter lower collector pipe 12, the a large amount of heats that absorb of 11 li of evaporimeter tubulations improve after the temperature blast pipe 9 that enters into evaporimeter by evaporimeter upper header 13 again and carry out next one and circulate.
