Solar energy assisted heat pump systems (SAHP) have been used in this application. SAHP system with solar collectors and the heat pump are combined into one unit so as to convey the solar energy to the refrigerant. The solar collector is used as the evaporator, where the refrigerant is directly vaporized by solar energy input. Due to the complicated technical issues associated with a combined system that provides air for space heating and domestic hot water, most of the previous studies have concentrated on water heater heat pump mechanism. The current work is aimed at examining the use of a new multi-functional heat pump (DX-SAMHP), air for space heating mutually with solar for domestic hot water without employing an auxiliary heater. Comprehensive experimental and analytical studies in the first of its kind have been performed on the new system. The novel system with ternary panels and the thermal performance of the collector has been examined in this study. Results indicate that the DX-SAMHP using solar inner and outer panels for space and water heating is a promising substitute for the existing DX-SAHP water heater. Compared to the conventional solar-assisted SAHP heat pump systems, the coefficient performance of the new design doubles that of the conventional DX-SAHP systems.

中冷气候多功能 DX-SAMHP 空气和水相互加热综合研究

太阳能辅助热泵系统 (SAHP) 已用于该应用。SAHP 系统与太阳能集热器和热泵合二为一，将太阳能输送到制冷剂中。太阳能集热器用作蒸发器，其中制冷剂通过太阳能输入直接蒸发。由于与为空间供暖和生活热水提供空气的组合系统相关的复杂技术问题，以前的大部分研究都集中在热水器热泵机制上。目前的工作旨在研究新型多功能热泵 (DX-SAMHP) 的使用，空气用于空间加热，太阳能用于生活热水，无需使用辅助加热器。对新系统进行了首次全面的实验和分析研究。在这项研究中已经检查了具有三元板的新型系统和集热器的热性能。结果表明，使用太阳能内外板进行空间和水加热的 DX-SAMHP 是现有 DX-SAHP 热水器的有前途的替代品。与传统的太阳能辅助 SAHP 热泵系统相比，新设计的系数性能是传统 DX-SAHP 系统的两倍。
