| Summary: | HVAC with wheel desiccant dehumidification (WDD) with a low ambient impact is more efficient system compare to the traditional systems. Hybrid desiccant cooling systems (HDCS) can be used to control indoor air quality (temperature and humidity) in commercial and industrial buildings. Hybrid desiccant cooling systems (HDCS) can be used as a technology for controlling indoor air quality (temperature and humidity) in many commercial and industrial buildings. Results increasingly show stringent guidelines for outdoor ventilation rate. Application of these systems depends on site-specific conditions and the loading rate, while; a high percentage of a building load can be latent. Desiccant cooling systems remove moisture from the air by using a wheel desiccant similar to condensation on coils in conventional systems. Climate conditions and buildings requirements should be analyzed and evaluated before using this system for any application. There are a few important variables, which drive performance and cost-benefit analysis. When more number of the just mentioned variables favor a hybrid desiccant system will be over a conventional system. In such conditions a detailed economic and performance analysis of a hybrid system is required. This study presents important variables analysis for different areas in Malaysia. The correlation shows that a high potentiality exists for using hybrid desiccant systems in all states of Malaysia. Moreover the corresponding electricity saving would be considerable. ©2010 ASHRAE. |
