摘要

Thermal environment evaluation in office over cooling period with direct cooling system of internal heat gain Part 2 In previous study, indoor thermal environment in occupied zone of direct cooling system of internal heat gain was evaluated by taking the space distribution and time change into consideration. A method that is similar to quasi-coupling simulation of contribution ratio of indoor climate (CRI) and energy-network model was used to realize the calculation of predicted mean vote (PMV). However, the control and performance change of the HVA-C system were not involved in previous evaluation, which cannot be ignored. In this study, the control and performance of the four components of the HVAC system, liquid cooling - heat recovery unit (HRU), active chilled beam (ACB), radiation partition (RP) and dry fan coil unit (DFCU) are modeled. Then, with considering control and performance change of the HVA.C system, a basic case study is conducted to evaluate the spatial and temporal PMV distribution of occupants. Results showed that the indoor thermal comfort was affected obviously by the operation-controlled strategy of water distribution system of ACB. As well as previous results, the differences of PMV value were smaller and the comfortability rates were higher than those by conventional system.%本報では、空調機器の発停制御と性能変動を含めて室內PMVの空間分布•時間変動性状の予測を達成するために、実験値に基づくHRU、RPの性能変動のモデル化と、メーカーの技術資料等に基づくACBのモデル化を行った。そして、前報で構築した空間分布考慮計算手法によるPMV計算の流れにモデル化した空調機器の性能及び発停制御を組込み、空調機器の発停制御が室内全員のPMVの空間分布•時間変動の性状に与える影響を検討した。
