Performance Review of Solar-Assisted Heat Pump Systems Using Solar Collectors, PV, and PVT Technologies

Abstract

Heat pumps (HP) can be used for a variety of residential, commercial, and industrial applications and offer a cost-effective replacement for conventional heat recovery systems. Hybrid systems that can be utilized for drying, heat storage, and water heating include solar-assisted heat pumps. Solar energy as a heat source for heat pump dryers improves performance and energy efficiency. This review aims to examine the concept of a solar collector, PV, and PVT technologies-assisted heat pump. The use of solar collectors to assist heat pump technology is a longstanding practice that remains in use today. Solar collectors that utilize direct solar heat sources and convert them into warm water or space heating are highly efficient. The concept of a PV and PVT-assisted heat pump is gaining popularity. The heat source utilized can be either single or multiple. Integrating a heat pump with a PVT as an evaporator result in higher heat performance. Using multiple heat sources is a more effective way to meet the cooling or heating requirements than relying on a single heat source. This review focuses on the mathematical modeling of a heat pump system integrated with PVT. Aspects of the mathematical model are critical for estimating the performance of heat pump systems in conjunction with solar collectors, PV, and PVT technologies. Readers who design and use heat pump technology must comprehend efficiency, COP, and configuration models.
