Abstract

A thermodynamic model is developed to analyze the thermal performance of two phase flow solar collectors, The well-known equilibrium homogeneous theory is used to model the two phase flow in the solar collectors. The resultant set of coupled ordinary differential equations for saturated pressure and quality of working fluids in the collector tubes are solved by an iterative procedure using a fourth order Runge-Kutta method. The results are then applied to determine the thermal performance of a solar assisted heat pump which uses two phase flow collector as the evaporator, The results indicate that even with the use of less e:xpensive bare solar collectors as evaporator for the heat pump, the heating coefficient of performance (COPH) as high as 6, can be obtained under realistic ambient conditions provided a proper matching exists between the collector's evaporative capacity and the compressor's pumping capacity. A transient system model is also developed in order to simulate the system performance under actual ambient conditions for a given location.
