Özet
In this study, performance, energy efficiencies of widely used conventional roof type packaged air conditioners and condenser side evaporative cooling roof type packaged air conditioners are compared. Evaporative cooling is provided by high efficient direct evaporative cooling pad. The main purpose of this application is to increase energy efficiency. The study was carried out for 50 kW cooling capacity unit considering working conditions of EUROVENT and tropical region. Pad usage, the same cooling capacity is achieved while the condenser air inlet temperature decreased and the compressor size reduced. COP, EER values increased by approximately 30%. In tropic region, the increment in COP, EER is much larger (50%).As a result, it is revealed that compressors and condensers can be downsized and energy efficient roof type air conditioners can be built by using pads.
