Currently, the unit prices of flat-plate solar collectors, vacuum tube solar collectors, and heat pipe solar collectors in the Chinese market are approximately 500 CNY/m 2, 250 CNY/m 2, and 500 CNY/m 2, respectively. A commonly used PCM, paraffin wax, is sold in China for about 10 CNY/kg.
Critical review of the combined aspects of technology, economy, and policy. Investigating the concerns of the user, government, and manufacturer. SWOT analysis and promotion strategies for solar-assisted air source heat pump.
The ESE, RTE, and exergy efficiency of the proposed system were 70.2%, 61%, and 50%, respectively. As listed in Table 4, the temperatures of supply and return water for the heating load were 80 and 30 °C. Under average solar irradiation operational conditions, the system needed about 6 h to raise 11.7 tons of VP-1 from 115 to 305 °C.
The results demonstrate that electricity storage efficiency, round-trip efficiency, and exergy efficiency can reach 70.2%, 61%, and 50%, respectively. Therefore, the proposed system has promising prospects in cities with abundant solar resources owing to its high efficiency and the ability to jointly supply multiple energy needs. 1. Introduction
