Abstract

This paper describes a liquid desiccant solar air conditioner (LDSAC), which is currently under development in Queensland, Australia. In the liquid desiccant technology the use of electricity is limited to circulating air and minor liquids. Cooling and heating require only heat from gas, co-generation or solar sources. Demand management is by storing desiccant. The LDSAC uses energy recovery and indirect evaporative cooling in a polymer plate heat exchanger (PPHE) with separated flow passages. The PPHE performs air-to-air recovery from building exhaust air into building supply air. Being an indirect process, supply air does not contact exhaust air thus allowing all contaminated and stale exhaust air to be used for energy recovery. The lithium chloride desiccant used is reconcentrated by hot water from a solar collector. Analysis showed that with sufficiently low regeneration temperature, it is feasible to obtain energy for desiccant regeneration from a solar collector or waste heat source. Preliminary work showed that for commercial applications considerable savings in electricity consumption in addition to a pay back period of less than 4 years could be achieved for the LDSAC. Its high ventilation rate also maximises indoor air quality.
