The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The present invention is based on the Evaporative Cooling Air-conditioning System of carbon dioxide monitoring and cold cascade utilization, as shown in Figure 1, by Evaporative Cooling Air Conditioning unit, carbon dioxide monitoring device and give, return air airduct forms.
Evaporative Cooling Air Conditioning unit comprises the air intake passage be arrangeding in parallel and the air exhaust passage that machine unit shell, consist of, and heat pipe vertically runs through air intake passage and air exhaust passage, is respectively heat pipe evaporator section 3 and heat pipe condenser section 9 in air intake passage and air exhaust passage.On the relative housing wall of air exhaust passage, be respectively arranged with exhaust outlet 10 and air-valve 8, the structure of air intake passage: be provided with air inlet 1 in housing sidewall one time, in an air inlet 1, be provided with new air-valve 23, press air intake direction, after an air inlet 1, be disposed with filter 2, heat pipe evaporator section 3, new air-return mixing section 4, indirect evaporation cooler 5, direct evaporative cooler 6 and pressure fan 7, pressure fan 7 passes in room by ajutage 15, in room, the port of ajutage 15 is provided with multiple air outlets 16, the top outside room is led to by Secondary Air exhaust duct 13 in the top of indirect evaporation cooler 5, the port part of Secondary Air exhaust duct 13 is provided with multiple Secondary Air exhaust outlets 14 that blow to roof, in room, on floor, be provided with multiple floors return air inlet 19, floor return air inlet 19 passes into respectively the exhaust outlet 10 of air exhaust passage and the new air-return mixing section 4 of air intake passage by backwind tube 11.
Between the top of indirect evaporation cooler 5 and Secondary Air exhaust duct 13, be provided with secondary exhausting machine 12.
The heat exchanger of indirect evaporation cooler 5 can adopt plate-fin, tubular type or dew point formula heat exchanger; Filler in direct evaporative cooler 6 can adopt the multiple materials such as papery, metal, porous ceramics, PVC; Heat pipe can adopt gravity assisted heat pipe, infiltration heat pipe, liquid-sucking core heat pipe etc.
Carbon dioxide monitoring device by switch board 20, be arranged at carbon dioxide monitoring device 17 in room and between the control circuit 21 that connects form, switch board 20 also by control circuit 21 and air-valve 8 and newly air-valve 23 be connected.
In air-conditioning system of the present invention, air blow and return send system form next time on adopting, and outdoor air is processed ventilation state point through Evaporative Cooling Air Conditioning unit, is sent into indoorly by pressure fan 7, and the waste heat in absorption chamber is remaining wet, meets the requirement of indoor temperature and humidity.Part air draft sends back to unit along backwind tube 11 and mixes recycling with new wind, and the condensation segment 9 that all the other air drafts are delivered to heat pipe by airduct carries out heat exchange, reclaims the cold of air draft.Return air district arranges carbon dioxide monitoring device 17, realizes the interlock of carbon dioxide monitoring device and air-valve 8 and new air-valve 23 by switch board 20, automatically regulates new return air ratio.The auxiliary air of indirect evaporation cooler 5 is discharged into roofing by secondary exhausting pipe 13, in the lower air lake 22 of roofing formation temperature, thereby reduce by roof conducts heat formation refrigeration duty.
The specific works process of air-conditioning system of the present invention is as follows:
Outdoor new wind enters Evaporative Cooling Air Conditioning unit, after filter 2 filters, with heat pipe evaporator section 3 heat exchange, transfer heat to heat pipe, temperature reduces, working medium in heat pipe is evaporated after absorbing heat, and under differential pressure action, the working medium after evaporation flows to heat pipe condenser section 9, at heat pipe condenser section 9, steam-condensation becomes liquid, and liberated heat is taken away by air draft, and liquid working medium is at the dirty product heat cal rod evaporator section 3 of capillarity of Action of Gravity Field or liquid-sucking core.Working medium in heat pipe circulates with this, realizes air draft cold recovery, the new wind of precooling.
At the carbon dioxide monitoring device 17 of indoor setting, realize the Real-Time Monitoring to conditioned area gas concentration lwevel, and by switch board 20, realize the interlock of carbon dioxide monitoring device and air-valve 8 and new air-valve 23.Carbon dioxide monitoring device 17 is provided with gas concentration lwevel limit value, if the higher limit of carbon dioxide monitoring device monitoring concentration is Cs, the rated value of normal work is Ce, and lower limit is Cx, when conditioned area gas concentration lwevel is during higher than higher limit Cs, air-valve 8 turns down automatically, strengthen resh air requirement, conditioned area gas concentration lwevel reduces, when gas concentration lwevel is reduced to rated value Ce, air-valve 8 keeps motionless, and blows to conditioned area with this kind of new air returning ratio; When conditioned area gas concentration lwevel is during lower than lower limit Cx, air-valve 8 leaves greatly automatically, reduces resh air requirement, and conditioned area gas concentration lwevel raises, and when gas concentration lwevel is elevated to rated value Ce, air-valve 8 keeps motionless.Thereby realize and utilize minimum resh air requirement control conditioned area gas concentration lwevel within the acceptable range, both met indoor air quality, fully reduced again the cooling load from outdoor air of system.
