“…Other researchers have worked on serial systems in which heat pump evaporator consists in a solar collector. The refrigerant circulates directly in the solar collector [13,14]. There are also indirect systems in which the heat pump and the solar collector are linked with a heat exchanger.…”

Nowadays, in several types of commercial or institutional buildings, a significant rise of transpired solar collectors used to preheat the fresh air of the building can be observed. Nevertheless, when the air mass flow rate is low, the collector efficiency collapses and a large amount of energy remains unused. This paper presents a simple yet effective mathematical model of a transparent transpired solar collector (TTC) with dual intake in order to remove stagnation problems in the plenum and ensure a better thermal efficiency and more heat recovery. A thermal model and a pressure loss model were developed. Then, the combined model was validated with experimental data from the Solar Rating and Certification Corporation (SRCC). The results show that the collector efficiency can be up to 70% and even 80% regardless of operating conditions. The temperature gain is able to reach 20 ∘ K when the solar irradiation is high.

“…A mathematical model for DX-SAHP calculations consisting of energy and exergy balance equations is proposed by [48] and applied to a vapour compression DX-SAHP serving a Turkish office. In practice, different SAHP systems -equipped with unglazed evaporator collectors, evaporator collectors and air collectors, exploiting solar and ambient energy -were tested for various applications (air-conditioning, water heating, and drying) under the Singapore meteorological conditions in [50], resulting that, in comparison with a conventional collector, the evaporator-collector efficiencies were higher, ranging from 80% to 90% with an 8.0 coefficient of performance of the heat pump system. A variety of further investigations aimed at modelling, designing and testing solar assisted heat pumps systems is available in literature [13,[51][52][53].…”

“…Meanwhile, as heat pump could recover heat from a variety of energy sources, integrating heat pump with renewable energy can bring great energy and cost saving [8,9]. Especially, solar-assisted heat pump (SAHP) has become one of the most prospective techniques with the enhanced performance and minified operating costs [10,11].…”
