分层或分层冷却的空调系统是一种在建筑物的下部占用区域提供空间冷却，而上部区域不制冷的系统。一般来说，由于产生热分层的自然浮力效应，上部区域将达到比下部区域更高的温度水平。本文报告的工作目的是通过实验确定设计用于冷却季节运行的分层/冷却系统的加热季节性能。有关冷却季节性能的详细信息，请参阅配套文件。

A stratified, or stratified-cooled, air conditioning system is one which provides space cooling in the lower, occupied zone of a building while leaving the upper zone uncooled. The upper zone will, in general, reach some level of temperature, higher than that of the lower zone, due to natural buoyancy effects producing thermal stratification.The intent of the work reported here was to determine by experimentation the heating-season performance of a system designed for cooling-season operation as a stratified/cooled system. Details of the cooling-season performance are reported in a companion paper.
