The delivery port of said solar thermal collector is provided with thermometer, Pressure gauge and automatic exhaust steam valve; The delivery port of said biomass furnace is provided with thermometer and Pressure gauge.
Said solar thermal collector is the tubulation pressure-bearing type solar heat collector.
Compared with prior art, advantage of the present invention is:
Utilize solar thermal collector and biomass furnace to form absorption type refrigerating unit, when solar radiation was sufficient, the heater assembly that the vapours that solar thermal collector provides directly gets into refrigeration machine provided energy to refrigeration machine; When sunlight irradiation is inadequate (it is temperature required only to rely on solar thermal collector not to be heated to water); Water is heated to uniform temperature by solar thermal collector earlier; And then get into biomass furnace and heat, make it to be heated to temperature required, thereby guarantee the normal continuously operation of refrigeration machine; At night or when not having sunlight, can provide energy to supply refrigeration machine normally to move separately by biomass furnace, so just guaranteed Absorption Refrigerator can be continuously, normally operation efficiently.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is explained further details.
As shown in Figure 1; A kind of solar energy and biomass energy combined absorption type refrigeration; Comprise tubulation pressure-bearing type solar heat collector 1 and Absorption Refrigerator 3; The delivery port of solar thermal collector 1 links to each other with heater 11 water inlets of Absorption Refrigerator 3, and the delivery port of heater 11 communicates with fluid reservoir 4, and the water inlet of solar thermal collector 1 communicates with fluid reservoir 4 through circulating pump 5, check valve 6; Also comprise biomass furnace 2, the delivery port of said biomass furnace 2 links to each other with heater 11 water inlets; The water inlet of said biomass furnace 2 communicates with fluid reservoir 4 through circulating pump 5, check valve 6, and its water inlet also links to each other with the delivery port of solar thermal collector 1; First stop valve 12 wherein is housed between the water inlet of the heater 11 of the delivery port of solar thermal collector 1 and Absorption Refrigerator 3; The delivery port of solar thermal collector 1 is equipped with second stop valve 13 between the water inlet of pipeline between first stop valve 12 and biomass furnace 2; The water inlet of the delivery port of biomass furnace 2 and heater 11 is equipped with the 3rd stop valve 14 to the pipeline between first stop valve 12, between the water inlet that exports to pipeline and biomass furnace 2 between solar thermal collector 1 water inlet of check valve 6 the 4th stop valve 15 is housed.
The delivery port of said solar thermal collector 1 is provided with thermometer 8, Pressure gauge 9 and automatic exhaust steam valve 10; Said solar thermal collector 1 is provided with illumination meter 7; The delivery port of said biomass furnace 2 is provided with thermometer 16 and Pressure gauge 17.
Like Fig. 2, shown in 3, said biomass furnace structure comprises chimney 21, heat-insulation layer 22, water tank 23, burner hearth 24, fire grate 25 and ventilating opening 18; Said burner hearth 24 peripheries are water tank 23, and water tank 23 peripheries are heat-insulation layers 22, and burner hearth 24 upper ends connect chimney 21, and burner hearth 24 bottoms are provided with fire grate 25, and fire grate 25 lower ends are provided with ventilating opening 18; Said water tank 23 upsides are provided with delivery port 27, and downside is provided with water inlet 26.
The course of work of apparatus of the present invention is following:
(1) solar refrigeration system: the condensed water in the fluid reservoir 4 gets in the tubulation pressure-bearing type solar heat collector 1 through circulating pump 5, check valve 6; When outdoor sunlight is abundant; Said solar thermal collector 1 produces high-temperature steam; Thermometer 8 detected temperatures via the exit reach 115 ℃ like temperature, and heater 11 devices that then directly get into Absorption Refrigerator 3 provide energy to refrigeration machine 3; Be back to fluid reservoir 4 after the heat exchange, and then by circulating pump 5 pressurization, get into solar thermal collector 1 heating again through check valve 6 and carry out the next round circulation; Do not reach 115 ℃ like temperature, then need get into the heating of biomass energy stove and accessory.
This system is abundant at outdoor sunlight, and intensity of solar radiation is greater than 1000W/m

(2) biomass energy refrigeration system: condensed water directly gets into heating in the biomass furnace 2 through circulating pump 5; Generation is higher than 115 ℃ steam (thermometer 16 by the exit detects); Get into heater 11 then and energy is provided, be back to fluid reservoir 4 after the heat exchange to refrigeration machine 3; Then by circulating pump 5 pressurizations, heating beginning next round circulation in check valve 6 gets into biomass furnace 2 again.
This system opens when evening or when not having sunlight.
(3) two system combined work: when sunshine inadequate; Only rely on solar thermal collector 1 not to be heated to water when temperature required; Earlier be heated to uniform temperature to water, and then get in the biomass furnaces 2 through second stop valve 13 and to heat, be heated to when temperature required by solar thermal collector 1; Get into heater 11 again and energy is provided, be back to fluid reservoir 4 after the heat exchange to refrigeration machine 3; Then by circulating pump 5 pressurization, get into through check valve 6 that heating restarts the next round circulation in the solar thermal collectors 1, thereby guarantee refrigeration machine can be continuously, efficient operate as normal.
