Abstract
The high-speed service area is located outside of the urban energy system. If there is no efficient energy saving technology, it will lead to a large amount of energy consumption. As an important ancillary facility along the expressway, the service area has a large demand for hot water due to the high density of human flow. Renewable energy should be fully utilized to make domestic hot water. In this paper, a water-cooled photo-voltaic thermal (PV/T) coupled heat pump hot water system model is proposed. The TRNSYS model for the system operation is built, and an operating experimental platform is set up to verify the model experimentally. The comprehensive performance of typical days in winter and summer was evaluated, and it was found that the average COP of the system was as high as 7.9 and 8.1 respectively. The photoelectric conversion efficiency is as high as 17.5% and 19.5%, respectively. This system has good technical adaptability in the high-speed service area, providing certain guidance for building the green and ecological high-speed service area.
