分析了三套管蓄能型太阳能和空气源热泵集成系统的特点,并建立了实验台来验证这一新型系统的可行性。实验台主要对系统的关键部件,三套管蓄能换热器的蓄、释能特性进行了研究。实验数据表明系统在直膨蓄冷模式时COP可达2.0～2.8,在蓄能供热模式时COP可达3.00～3.75,同时蓄释的供热模式时系统COP可达3.31～3.45,实验结果证明三套管蓄能型太阳能和空气源热泵集成系统是可行的,可以在多种模式下高效、安全运行。
The characteristics of the integrated system of three bushing solar energy storage systems and air source heat pump system were analyzed. A test bench was set up to verify the feasibility of the new system. The experimental bench mainly studies the storage and release characteristics of the key components of the system and the three-casing energy storage heat exchanger. The experimental data show that the COP can reach 2.0 ~ 2.8 in the direct-charging cooling mode and 3.00 ~ 3.75 in the energy-storing and heating mode, and the COP of the system can reach 3.31 ~ 3.45 when the heat-releasing mode is released. The experimental results show The three-bushing energy storage solar and air source heat pump integrated system is feasible and can operate efficiently and safely in a variety of modes.
