Abstract

Personal comfort systems (PCSs) are commonly used indoors as energy-efficient alternatives to traditional whole-space heating and cooling to improve occupant thermal comfort and acceptability under a variety of thermal conditions. Despite the fact that numerous studies have shown that using PCSs has beneficial effects, no definitive conclusions on the effectiveness of PCSs on thermal comfort enhancement have been reached. Furthermore, detailed analyses of specific indoor thermal conditions that appear to be the most promising require additional research. We conducted a thorough systematic review in this chapter to summarise, analyse, and compare findings from eligible documented studies on the effects of various PCSs on occupant thermal comfort. We also investigated the energy efficiency of the selected PCSs. The effects of total cooling or heating area, as well as the types of PCSs, on the perceptual responses of occupants, were specifically addressed. This systematic review will serve as a starting point for selecting highly energy-efficient and effective personal comfort systems to improve building occupant thermal comfort.
