Abstract
An engineering-scale solar water heater system assisted by heat pump was developed based on a modularized structure. The subunits of modularized system include vacuum solar energy collectors, air source heat pump, heat storage & supplying system and control panel. All devices could be controlled and monitored centrally. Energy source of this system was composed of solar energy (70%), air thermal energy (20%) and electric power (10%). The system has advantages of high average annual comprehensive energy efficiency and elementary energy utilization efficiency. The product can be employed in central heat water supplying project with a capacity of more than 6 ton, in such facilities as residential districts, hotels, restaurants, dormitories, bathing centers and so on. The economical efficiency is better as the scale is bigger. The project has been supported by innovation funds of Science and Technology of Chinese Ministry of Science and Technology (MOST), being applied in a residential district successfully as a demonstration project of renewable and new energy by Chinese Ministry of Construction.
