Abstract

The performance of liquid desiccant dehumidification system (LDDS) combined with vapor compression refrigeration system (VCRS) has been experimentally investigated. LDDS is used in order to enhance outdoor quality of air by extracting the moisture from humid air and VCRS deals with sensible cooling of air. The system performance has been enhanced by proper mixing of outdoor air with CaCl2 as a desiccant in cellulose pads of different flute height in dehumidifier. The experiments have been executed at Lovely Professional University (LPU), Jalandhar, India [31°15′17.98″ (latitude) North and 75°42′56.382″ (longitude) East] at 55 blocks. In this study, moisture removal rate (MRR) and dehumidification effectiveness (\(\varepsilon _{{{\text{deh}}}}\)) are calculated to evaluate the performance of dehumidifier. Also, the coefficient of performance (COP) of VCRS with and without LDDS is calculated. These parameters are studied at different inlet air temperatures and humidity ratio. The maximum increase in (COP of VCRS)with LDDS is 9.84%, when the temperature of air at the inlet is varying from 30 to 50 °C by keeping constant humidity ratio at inlet as 8 g/kg of dry air. The maximum increase in MRR is 51.58%, when inlet air humidity ratio is varying between 8 and 18.8 g per kg of dry air keeping constant inlet air temperature of 30 °C.
