Retrofit Design And Optimization Of PVT-ASHP Plant In Tropical Healthcare Facility.
A proposed large scale PhotoVoltaic Thermal (PVT) system integrated with existing Air Source Heat Pump (ASHP) hot water plant in a healthcare facility located in tropical ambient has been simulated and optimized. Healthcare facility, which is characterized, by consistent thermal and energy demand, day and night has been selected due to its high economic potential for integration of PVT system with typical ASHP plant widely installed in Malaysia’s healthcare facility. Make-up water is pre-heated by the PVT system before entering the ASHP’s calorifer and thus reducing the energy input for ASHP as well as generating electricity for hospital consumption. This configuration is selected because it does not require any major modification and minimal disruption to the existing, operational ASHP system. In search of economically optimum system configuration, 3.87m2/bed PVT collector area per bed ratio, 0.04 m3/m2 and eight numbers of PVT collector connected in series proved to be the most economically superior design at a total solar fraction of 198.2%, thermal solar fraction of 78% and an electrical solar fraction of 336%. The results signify the potential of integrating large scale PVT collector systems with existing ASHP plants, particularly in the healthcare facility.
