The energy demand for cooling and air-conditioning has increased heavily the last years. In order to reduce the electricity consumption, solar cooling promises to be an attractive application. To operate some these kinds of systems, a relatively high temperature (90-165°C) must be provided for efficient operation. However, because of the relatively low temperatures attainable when flat plate collectors are used, concentration of solar radiation becomes necessary. One of the most attention solar concentrators is the Compound parabolic Concentrators (CPC). Thus in this paper the CPC will be studied to be suitable for solar cooling application. For practical application, the system should be studied under outdoor conditions. Therefore the feasibility of non-evacuated CPC system for unsteady state is analyzed under outdoor conditions, where the wind velocity and ambient temperature variations are considered depending on an actual data which are taken from Meteorological Station in Misurata Libya. Simulation results showed that at a design in which the outlet fluid temperatures to be 150°C, the system recorded a reasonable efficiency along the year operation at concentration ratio Ca = 5. Therefore, using the CPC with cooling system, and with this concentration ratio, is a good application and promise for use. |
