34th, stop valve 37 and water circulating pump 32, absorber plate 22 absorbs sunshine temperature and raises, and heats sorbing material 27, makes the suction
Hydrone evaporation in enclosure material 27 produces vapor, and the vapor is through filter layer 21 to condensed layer 24 and solidifying with described
Chilled water coil 25 in knot layer 24 condenses into condensation water 26 after exchanging heat, and under gravity, along chilled water coil 25 baffle plate is gathered in
At 30.Water in chilled water coil 25 is absorbed after the heat of the vapor is heated in the presence of water circulating pump 32, by cutting
Only valve 34 is flow at heat exchanger 42 after heat exchange along water supply line 47, and condensed layer 24 is flow back into by stop valve 37 along water return pipeline 46
It is middle to continue to exchange heat.
At night, the 3rd stop valve 33, stop valve 35, stop valve 36, stop valve 38, water circulating pump 31 and recirculated water are opened
Pump 32, closes stop valve 34 and stop valve 37, and condensation water 26 absorbs the heat of water in chilled water coil 25 and evaporates generation vapor,
Vapor is through the filter layer 21 to adsorption layer 20, and adsorbed material 27 absorbs, the water and condensate in chilled water coil 25
It is cooled after 26 heat exchange, in the presence of water circulating pump 31, is flow to along the water supply line 49 by the stop valve 35 described
After exchanging heat at heat exchanger 41, it is flow back into chilled water coil 25 by stop valve 38 along the water return pipeline 48, sorbing material 27 is inhaled
The vapor after condensation water 26 evaporates is received, amount of heat is released, the water in hot-water coil pipe 28 absorbs sorbing material 27 and releases heat
After be heated, in the presence of water circulating pump 32, flow at heat exchanger 42 along the water supply line 47 by the 3rd stop valve 33
After heat exchange, it is flow back into the hot-water coil pipe 28 by the stop valve 36 along water return pipeline 46, in the hot water storage tank 40
Water storage in the presence of hot water circulating pump 55, at hot water feeding pipe road 52 to heating dish 57 with evaporation cavity 62 in evaporation liquid
It is cooled after 61 heat exchange, cooling water flows back to hot water storage tank 40 again along hot water backwater's pipeline 51 to be continued to be exchanged heat with heat exchanger 42,
In evaporation cavity 62 evaporation liquid 61 absorb heating coil 57 in water heat and flash to boil-off gas, the boil-off gas due to
Density contrast effect moves up to pressurizing chamber 58, promotes piston 63 to travel forward and force the water 66 in liquid storage chamber 64 to be pressed
In entering to filter suction inlet 65, pressurizing chamber 58 is increased due to the boil-off gas, and its pressure continues to increase, and further promotes piston 63
Move forward, force water 66 to flow into the water-filling interlayer 3 of automatic temperature-control subsystem 1 by check valve 74 along pipeline 67, after
And the water storage in cold water storage tank 39 is in the presence of cold water circulation pump 56, at cold water supplying pipe road 53 to cooling coil 60 with
Cold water storage tank 39 is flowed back to again after boil-off gas heat exchange in pressurizing chamber 58 along cold-water return pipeline 54 to continue and heat exchanger 41
Heat exchange, after the boil-off gas in pressurizing chamber 58 are cooled with the heat exchange of cooling coil 60, due to Action of Gravity Field, flows back to evaporation cavity 62
In, because boil-off gas are cooled, pressure reduces pressurizing chamber 58, and piston 63 is moved backward under the pulling of spring 59, makes liquid
Pressure in storage chamber 64 reduces and produces draft and water is extracted from well 70, and water passes through the edge of check valve 68 under the draft effect
In the influent storage chamber 64 of pipeline 67, and so on move, by the hydraulic pressure in liquid storage chamber 64 to automatic temperature-control
In the water-filling interlayer 3 of system 1.
In summer, when the drip irrigation subsystem 2 runs, when ambient temperature is higher than indoor temperature, need to weaken outer
Boundary's environment with interior heat transfer when, opening stop valve 9, to adjust the water-filling interlayer 3 in filled water amount, make the water-filling interlayer
Water level in 3 is in lower position, now, in the water-filling interlayer 3 based on air conduction, supplemented by the heat conduction of water, air

Property, make the automatic temperature-control subsystem 1 reach the effect for automatically adjusting heat transfer.
In the winter time, when the drip irrigation subsystem 2 runs, when ambient temperature is higher than indoor temperature, need to increase outer
During the heat transfer of boundary's environment and interior, opening stop valve 11, to adjust the water-filling interlayer 3 in filled water amount, press from both sides the water-filling
Water level in layer 3 is in higher position, now, in the water-filling interlayer 3 based on the heat conduction of water, supplemented by air conduction, water
Thermal conductivity factor it is larger, heat conductivility is relatively strong, enhances the heat conductivility of the water-filling interlayer 3, and then increased the external world
To indoor heat output, when ambient temperature is further raised, opening stop valve 12 makes water in the water-filling interlayer 3 to environment
Position is in extreme higher position, and now the water-filling interlayer 3 is almost the heat conduction of water, and the thermal conductivity factor of water is big, further increases outer
Boundary's environment, when the drip irrigation subsystem 2 runs, when ambient temperature is less than indoor temperature, needs to indoor heat output
When weakening the heat transfer of external environment and interior, opening stop valve 9, to adjust the water-filling interlayer 3 in filled water amount, make described filling
Water level in water interlayer 3 is in lower position, and now, main based on air conduction in the water-filling interlayer 3, the heat conduction of water is
