Performance of Cross-Cooled Desiccant Dehumidifiers
Journal of Solar Energy Engineering, 1983A cross-cooled silica gel desiccant dehumidifier model was designed, built, and tested. The performance of the unit was studied as a function of the inlet process stream dew point, process stream and cooling stream flow rates, and regeneration stream temperature and dew point. The tests were also simulated by a computer program and were compared to the

Passive Cooling of Photovoltaics with Desiccants
2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017As part of efforts to reduce photovoltaic (PV) costs and improve reliability/durability, temperature control needs to be closely examined in a number of ways including novel passive cooling technology. Modest PV module operating temperature reductions can increase PV power output by 100% or more.

Abstract Solid desiccant cooling technology has become a research focus for its features of energy-saving and eco-friendly. However, widely adopted rotary desiccant wheel cooling system can't realize inner-cooling dehumidification process. In this paper, a novel self-cooled solid desiccant cooling system (SCDHE) is developed by integrating desiccant ...

Use of compound desiccant to develop high performance desiccant cooling system
International Journal of Refrigeration, 2007Abstract The paper is aimed to develop a high performance rotary solid desiccant cooling system using a novel compound desiccant wheel (DW). The unique feature of the desiccant wheel is that it can work well under a lower regeneration temperature and have a higher dehumidification capacity due to the contribution of the new compound desiccant ...

Man-portable personal cooling garment based on vacuum desiccant cooling
Applied Thermal Engineering, 2012Abstract A man-portable personal cooling garment based on the concept of vacuum desiccant cooling (VDC) was developed. It was demonstrated with cooling pads that a cooling capacity of 373.1 W/m2 could be achieved in an ambient environment of 37 °C. Tests with human subjects wearing prototype cooling garments consisting of 12 VDC pads with an overall ...

Performance of an open-cycle desiccant cooling system using advanced desiccant matrices
Heat Recovery Systems and CHP, 1989Abstract The design and off-design performance of an open-cycle cooled-bed desiccant cooling system, using advanced desiccant matrices, is presented. The performance of the cooled-bed dehumidifier, the principle component of the cooling system, is simulated using a numerical model that includes the heat and mass transfer resistance within the ...

Second Law Analysis of Desiccant Cooling Systems
Journal of Solar Energy Engineering, 1982A second law analysis of constant pressure open cycle cooling systems was performed in order to assess the potential performance of desiccant cooling systems. The results yield upper bounds which are independent of the nature of the desiccant. Calculations carried out for a wide range of operating conditions show that the performance of these open ...
