| Hybrid air-conditioning system powered by solar thermal energy  DuCool is launching the DuHybrid cooling and dehumidification system which combines optimal energy savings and 24/7 operation. The DuCool DuHybrid system is powered by solar thermal energy when available and automatically switches to electric power when needed. The system can also be integrated with a cogeneration system and can be powered by other renewable energy sources or waste heat. The system can be supplied in one of the three configurations, 1400CFM, 2400CFM and 3400CFM, that cover a broad range of commercial and industrial needs for air conditioning and dehumidification.The DuHybrid system operates in one of two modes. The Renewable Energy mode is the default mode of operation. Based on the application, in this mode the unit can generate over 20 TR (tons of refrigeration) of cooling and dehumidification using renewable energy sources such as solar thermal and geothermal water. The second mode of operation is the Electric mode; in this mode of operation an embedded compressor is activated to enable efficient cooling and dehumidification, by utilizing the waste heat of the compressor as an internal energy source. The DuHybrid is extremely efficient in both operating modes; overall reduction in energy consumption can surpass 60% (subject to Renewable Energy source) when compared to a standard air conditioning unit. Additional benefits of the DuHybrid system include the ability to control humidity and temperature independently (variable sensible heat ratio). This guarantees that the required conditions, both temperature and humidity, are achieved in the most energy efficient way. The DuHybrid's liquid desiccant cooling process eliminates 91% of the bacteria in the air in a single pass and removes over 80% of all particles larger than five microns including allergens such as pollen, dust and other airborne particles. These air scrubbing qualities are inherent to all of DuCool's cooling and dehumidification systems. write your comments about the article :: © 2009 Construction News :: home page |
