“…Barnwal et al [24] analyzed the power needed to operate a fan and determined the convective heat transfer coefficient. Another study proposed a system of air-type PVT collectors coupled with compression refrigerators [25]. The heated air from the air-type PVT collectors was combined with heat released from condensers, and the air (a gaseous refrigerant) was dehumidified to achieve a high temperature.…”

A heat-recovery ventilator (HRV) effectively conducts ventilation by recovering waste heat from indoors to outdoors during heating periods. However, dew condensation associated with the HRV system may arise due to the difference between the indoor temperature and the very low outdoor temperature in winter, and this can decrease the heat exchange efficiency. These problems can be solved by the pre-heating of the incoming air, but additional energy is required when pursuing such a strategy. On the other hand, an air-type photovoltaic thermal (PVT) system produces electricity and thermal energy simultaneously using air as the heat transfer medium. Moreover, the heated air from the air-type PVT system can be connected to the HRV to pre-heat the supply air instead of taking in the cold outdoor air. Thus, the ventilation efficiency can be improved and the problems arising during the heating period can be resolved. Consequentially, the heating energy required in a building can be reduced, with additional electricity acquired as well. In this paper, the performance of an air-type PVT system coupled with an HRV is assessed. To do this, air-type PVT collectors operating at 1 kW p were installed in an experimental house and coupled to an HRV system. Thermal performance and heating energy required during the winter season were analyzed experimentally. Furthermore, the electrical performances of the air-type PVT system with and without ventilation at the back side of the PV during the summer season were analyzed.

“…A simulation design of a hybrid PV/T assisted desiccant integrated HA-IR drying (HPIRD) system, consisting of a photovoltaic air collector (PVAC) and a desiccant silica gel bed (DB) was developed and a reduction in drying time, drying rate and energy consumption was observed [233]. A computer model to determine the thermal absorption factor of crystalline silicon solar cells was developed, which increased the total absorption factor to 87% [234]. An electrical and thermal model of a solar photovoltaic thermal PV/T air collector was developed, using the temperature values of the solar cell, back surface, outlet air and electrical parameters, like short circuit current, current at the maximum power point, open circuit voltage, and voltage at the maximum power point, and it was found that the thermal, electrical and overall energy efficiencies were about 17.18%, 10.01% and 45%, respectively [235].…”

“…Parametric studies showed that the thermal efficiency could reach 80% under favorable collector length and mass flow rate conditions. Sukamongkol et al [42] studied the dynamic performance of a condenser desiccant for air conditioning energy reduction with the use of double-pass PVT/a collector. The thermal energy generated by the system was able to produce warm dry air as high as 53 • C and 23% relative humidity.…”

The market of solar thermal and photovoltaic electricity generation is growing rapidly. New ideas on hybrid solar technology evolve for a wide range of applications, such as in buildings, processing plants, and agriculture. In the building sector in particular, the limited building space for the accommodation of solar devices has driven a demand on the use of hybrid solar technology for the multigeneration of active power and/or passive solar devices. The importance is escalating with the worldwide trend on the development of low-carbon/zero-energy buildings. Hybrid photovoltaic/thermal (PVT) collector systems had been studied theoretically, numerically, and experimentally in depth in the past decades. Together with alternative means, a range of innovative products and systems has been put forward. The final success of the integrative technologies relies on the coexistence of robust product design/construction and reliable system operation/maintenance in the long run to satisfy the user needs. This paper gives a broad review on the published academic works, with an emphasis placed on the research and development activities in the last decade.
