“…The solid-packed bed can withstand substantial moisture levels, but the rotating honeycomb gets more constant humidity in process air. The two desiccant dehumidifiers have advantages and disadvantages [48][49][50][51][52][53]. 4) compares the pattern of the annual COP for liquid and solid desiccant systems based on the working hours of each system.…”

Due to the growing expense of fossil fuels and other environmental issues, it is crucial to reduce the energy cost of built environment cooling systems without sacrificing indoor air quality and comfort levels. One option in this area is solid desiccant dehumidification-assisted cooling systems, which employ alternative energy sources like solar and biomass and are also environmentally beneficial by the minimal requirement of refrigerants. The present review discusses the performance analysis of different solid desiccants readily accessible on the market and their composites. Better moisture absorption and a lower regeneration temperature are qualities of a better desiccant. The review also discusses the various solid desiccant dehumidifier designs, their benefits, and their disadvantages. Solid desiccant dehumidifiers now come in various combinations, considerably enhancing system performance. The exergy efficiency of desiccant-integrated evaporative cooling is up to 21.5%, comparable with another HVAC system. A summary of the performance parameters has also been created to assess system performance further. This study will benefit innovation and advancement in solid desiccant materials in the air conditioning market.

“…Because of its potential advantages and applications desiccant cooling can be a promising technology in Pakistan to cope with cooing demand in various sectors. There are limited studies on the use of desiccant cooling in Pakistan (Khalid et al, 2009;Ali et al, 2015;Farooq et al, 2020;Kashif et al, 2020). Mostly these studies describe simulation work or solar-assisted desiccant system.…”

“…The plant hybridization generally requires more available surface. As a consequence, several research projects dealt with the potential application in desiccant cooling system of both water-cooled and air-cooled PV/T technologies [ [44] , [45] , [46] ]. Unfortunately, those devices are still expensive, and they are not yet beneficiary of incentive schemes, so that their adoption can be not cost-effective.…”

The rotary desiccant wheels application in the air conditioning systems are used for the air dehumidification by means of hygroscopic layers for water vapor adsorption. Nevertheless, external heat sources are required for water desorption to close the air treatment cycle. This paper investigates on the possibility to integrate in that cycle a new component, such as the trans -critical CO 2 heat pump, to reduce the contribution of external thermal sources. In so doing, the high temperature waste heat discharged by the heat pump hot sink can be fruitfully exploited. Additionally, a PV array has been added to the typical layout based on the solar collectors, in order to assure the heat pump electrical driving. The energy analysis is carried out by calculating the energy performance indicators of the whole cooling system, simulating it by a dynamic model built in the MATLAB SIMULINK environment. Specifically, an air handling unit has been properly sized to supply cooling load to a reference conference hall of 1200 m 3 , with changes in boundary conditions (i.e. solar radiation, daily temperature and relative humidity variations). Indeed, three different cities representing the most typical Italian climatic zones, have been considered for assessing the proposed technical option suitability.
