Proceedings. Effect of return air leakage on air conditioner performance in hot-humid climates. Symposium on Improving Building Systems in Hot and Humid climates [10, 13-14 may 1996, Texas].



An experimental study was conducted to quantify the effect of return air leakage from hot/humid attic spaces on the performance of a resedential air conditioner. Test were conducted in psychrometric facilities were temperatures and humidities could be controlled closely. Returns air leakage from hot attic spaces was simulated by assuming adiabatic mixing of the indoor air at normal conditions with the attic air at high temperatures. Effective capacity and Energy Efficiency Ratio both decreassed with increased return air leakage, However, power consumptionwas relatively constant for all variables except outdoor temperature, which meant that for the samepower consumption, the unit delivered much lower performance when there was returns air leakage. The increase in sensible heat ratio (SHR) with increasing leakage showed one of the most detrimental effects of returns air leakage on performance..
