| 内容記述 | 太陽熱温水器を駆動熱源とするデシカント空調機と顕熱処理用の冷却コイルを組み合せた太陽熱利用デシカント空調システムについて,全冷房出力に対するデシカント空調部の寄与割合に着目し,室内全熱負荷,顕熱比,換気回数の影響を調べた.処理風量と太陽熱温水器の循環水流量が室内顕熱負荷と連動する本システムでは,顕熱負荷の増加に伴って除湿機再生温度が低下することに加えて,顕熱交換器の低温側空気中の外気割合が増加することで給気温度が土昇し,デシカント空調プロセス部の寄与割合は低下する.換気回数が増加しても再生空気入口温度が低下して顕熱交換器で給気温度が低下するため,冷却コイルに求められる顕熱処理能力は増大しない. Solar water heater is an useful heat source for the desiccant cooling because it is clean, renewable and has a low cost. This paper mainly discusses about the influences of cooling load and air change rate of a room on the performance of the desiccant cooling system consisted of a desiccant wheel, thermal wheel, two evaporative coolers, a cooling coil, flat plate solar water heater, and air heater. The cooling system is assumed to be applied to an office room of 250m^3 in volume. Produced dehumidifying performance per unit air volume by the desiccant cooling process decreased with increase in sensible cooling load since the regeneration air temperature decreased due to simultaneous increase of the amount of regeneration air flow and flow rate of water circulating in the solar water heater. However, temperatures of hot water and regeneration air supplied from solar water heater of 20m^2 was high enough to produce a sufficient dehumidifying performance per unit time even in the total cooling load of 22.2kW and SHF=0.9 since the increase in the amount of process air flow compensated the decrease in dehumidifying performance per unit air volume. On the other hand, required amount of dehumidification per unit time increased as the SHF value decreased. Therefore, temperature of hot water supplied from solar water heater of 20m^2 did not reach a sufficient level for the indoor air condition at SHF 0.65 and 12kW the sensible heat load. In this case, additional heat input between 1.7 and 20.0kW was required depending on the amount of solar heat obtained by the solar water heater. The ratio of cooling power produced by the desiccant cooling process to the total cooling power of the whole of the cooling system (desiccant cooling process+cooling coil) was around 0.2-0.3 when the SHF value was 0.65 since the obtained dehumidifying performance was just enough to satisfy the required humidity for the room. On the contrary, required dehumidifying performance became small when the SHF value was large and desiccant cooling could produce a surplus dehumidifying performance resulting in a sensible cooling effect of the evaporative cooler. Thus the required cooling power of the cooling coil became lower at higher SHF condition. Influence of the air change rate on the performance of the cooling system was also investigated. The ratio of cooling power produced by the desiccant cooling process increased in higher ventilation rate since the required amount of dehumidification became larger. However, the ventilation rate had no effect on the required cooling power of the cooling coil, for the inlet air temperature of the regeneration side became lower resulting in low temperature dry air at the process outlet of the thermal wheel. | |||||||||
