A Field Study of a Low Flow Internally Cooled/Heated Liquid Desiccant Air Conditioning System: Quasi Steady and Transient Performance

Abstract

The field performance of a lowflow internally cooled/heated liquid desiccant air conditioning (LDAC) system is investigated in this paper. The quasisteady performance (sensible and latent heat transfer rates, coefficient of performance (COP), and uncertainties) of the LDAC system is quantified under different ambient air conditions. A major contribution of this work is a direct comparison of the transient and quasisteady performance of the LDAC system. This paper is the first to quantify the importance of transients and shows that, for the environmental and operating conditions in this paper, transients can be neglected when estimating the energy consumption of the LDAC system. Another major contribution of this work is the development and verification of a new method that quantifies (with acceptable uncertainties) the quasisteady performance of a LDAC system from transient field data using average data.
