Abstract | This report presents simulation procedures and results of the following systems: 1) Conventional air source heat pump and solar water heating systems for process heating applications. 2) Combined solar water heater-heat pump system for process heating applications. 3) Combined solar water heater-absorption chiller system for space cooling and 4) Combined solar water heater-heat pump-absorption chiller system for space cooling. The performance of the systems are examined with low to high temperature process heating and constant cooling load. The fraction of the require energy supplied by solar and auxiliary are determined. The simulation of the systems are done taking solar radiation and weather data of Bangkok. From simulation it was seen that for a load of 37.98 MJ/hr and load temperature of 54.5 c for conventional solar system using 65 m2 collector area solar fraction was 72.87% while that for combined solar plus heat pump system was 77.88% Assuming multiplication faction of 4 for production of electricity from fuel the effective thermal solar fraction for the above condition turn out to be 18.84% From this it is evident that the conventional system to be more advantageous than the combined system. Again, for space cooling load of 3 ton for conventional system using collector area 65 m2 solar fraction was 37.5% while that of combined system solar plus heat pump system fraction was 56.67% Here also the conventional solar system seems to be better than combined system. |
