Analysis and performance enhancement of newly designed solar based heat pump for water heating application

Abstract

Owing to its use of solar radiation and ambient energy, solar based heat pump water heaters are environmentally friendly. Several recommendations for system optimization are offered based upon the experimental study and thermodynamics analysis to enhance the efficiency of the model. The goal of this work was to create and maintain a solar based heat pump prototype as well as to propose a comprehensive theoretical examination into the social-economic and energy efficiency of a new solar based heat pumping (SHP) model for water heater application. The ultimate focus of the performance evaluation and interpretation is to evaluate the viability and logical consistency of deploying a solar-based heat pump as an auxiliary water heating mechanism during local weather scenarios. Subsequently, a modelling approach is created for optimizing the performance. Moreover, the suggested system’s performance characteristics are assessed using the Solar Collector Efficiency (SCE) and Coefficient of Performance (COP). The optimal case’s simulation results demonstrate that the solar-based heat pump’s average COP is about 9.0. The comfortable level of temperature could be accomplished when a pleasant indoor temperature reaches 92.6 percent of the whole heating season. Traditional air source heat pump systems may not be as promising for domestic use in cold temperature areas as the optimal proposed system does.
