INTRODUCTION
In the last decade, all-desiccant and hybrid desiccant systems have emerged as an substitute to traditionalisti vapor compression systems for cooling and conditioning air in some type of buildings such as staged in Refs. (1-6). A typical hybrid scheme combine a desiccant cooling system with a traditionalisti vapor compression cooling scheme was staged in Ref. (2). The main goal of application of hybrid desiccant cooling schemes is using the high capability of desiccants in meeting the latent load of buildings. When combining with the high capability of vapor compression scheme in meeting the sensible load of buildings, the schemes efficacy could be enhanced. Conventional vapor compression systems use a very low evaporator temperature in order to meet the…

From the author: HVAC with wheel desiccant dehumidification (WDD) with a low ambient affect is more effective system compare to the traditionalisti systems. Hybrid desiccant cooling schemes (HDCS) may be used to control indoor air quality (temperature and humidity) in mercantile and industrial buildings. Hybrid desiccant cooling systems (HDCS) may be employed as a engineering science for controlling indoor air quality (temperature and humidity) in a lot of mercantile and industrial buildings. Results growingly show stringent guidelines for outdoor ventilation rate. Application of these systems depends on site-specific conditions and the loading rate, while; a high part of a building load may be latent. Desiccant cooling schemes remove moisture from the air by using a wheel desiccant similar to condensation on coils in established systems. Climate conditions and buildings requirements must be analyzed and evaluated before using this scheme for any application. There are a few essential variables, which drive performance and cost-benefit analysis. When more number of the just noted variables favor a hybrid desiccant scheme will be over a traditionalisti system. In such conditions a elaborated economic and performance analysis of a hybrid system is required. This study presents important variables analysis for dissimilar areas in Malaysia. The correlation shows that a high potentiality exists for using hybrid desiccant schemes in all states of Malaysia. Moreover the corresponding electricity saving would be considerable.
