Thermodynamic analysis of a novel energy-efficient refrigeration system subcooled by liquid desiccant dehumidification and evaporation

Performance evaluation of an ejector subcooled vapor-compression refrigeration cycle

“…These methods include the air conditioning system utilizing a cold storage unit as a subcooler, the heat pump system with ice storage subcooler and the refrigeration system subcooled by liquid desiccant dehumidification as well as the CO 2 transcritical vapor compression cycle with thermoelectric subcooler [11][12][13][14][15]. Relevant analytical or experimental results in the literatures all confirmed improvements in performance when using the new subcooling methods in vapor compression refrigeration cycles.…”

Recent developments in solar assisted liquid desiccant evaporative cooling technology—A review

“…It was also noted that cooling the water relatively at lower temperatures could lead to higher values for dehumidification effectiveness and moisture removal rate in an internally cooled dehumidifier. She et al [20] proposed a new energy efficient liquid desiccant dehumidification and evaporation system and compared the performance characteristics of the new system with a conventional vapour compression refrigeration system. The findings indicated that proposed system achieved higher COP than conventional systems and even higher than the reverse Carnot cycle under the same operation conditions.…”

New airborne pathogen transport model for upper-room UVGI spaces conditioned by chilled ceiling and mixed displacement ventilation: Enhancing air quality and energy performance

“…The air quality is assessed in a 5 m  5 m  2.8 m office space in Beirut conditioned by CC/mixed DV during the cooling season. The humidity of the air is assumed to be removed in an economical method using desiccant dehumidifier wheel [58,59] (negligible energy consumption) so that the coil load is only for sensible cooling. The office consists of two external walls (south and west oriented) with two internal partitions and the floor is considered above a conditioned space at 25°C.…”
