Abstract

Due to the higher practicability and annual utilization, the dual-use heat pump systems are more popular in practical demonstrations. Although there are various kinds of designs for such system, most of them focus on the performance enhancement in heating mode and pay little attention to the cooling capacity. The proposed three-dimensional composite heat exchanger structure based on a concentrator plus fins could not only improve the total output in heating mode but also lower the condensing temperature by shading the solar energy with the concentrator to improve the cooling COP. Different from previous study, this paper focus on the improvement potential in cooling mode of the novel system. Experiments are carried out and used for the validation of mathematical model. By analyzing the physical state of the refrigerant during the cycle, the mechanism is revealed in detail and depth. Results show that the dryness decrease at evaporator inlet caused by the condensing temperature drop is the main reason for capacity improvement, while the mass flow rate also has crucial impact. With high mass flow rate, the mean cooling COP of proposed system could be as high as 3.1, 0.16 higher than the system without concentrator shading.
