摘要: Abstract Heat exchangers for heat pump condensers and evaporators are usually designed considering rated load conditions. Residential pumps residential air conditioners operate considerably longer at part conditions than This study investigated the difference between a design condition in exchanger path design. The optimal number of paths each was selected thermal resistance ratio. Results show that transfer rates condenser with based on under 84%, 51%, 33% were 18.29%, 27.58%, 42.58% greater rate optimized conditions, respectively. Considering all maximum average derived using weighting factor system performance evaluation criteria. results demonstrated changed when considered
