The performance of a solar collector is determined by how effectively it transfers heat to a working fluid. This section focuses on techniques to enhance the heat transfer from the collector. (The passage originally stated that the section is dedicated to enhancing the performance of the collectors discussed in the previous section, but it does not directly answer the question without additional context about how the performance enhancement relates to heat transfer.)
Solar collectors' application in public buildings has been on the rise in European countries . This can be attributed to the high cost of energy supply, which has recently skyrocketed due to the ongoing crisis in Ukraine. This section summarises the various applications of solar collectors in public buildings and their cost-saving features.
Accordingly to Cirimina et al. the most important parameter of an opaque solar collector with perforations is the heat exchange efficiency and its value depends on: the diameter and the pitch of the perforations, the thickness of the absorbent plate and the material from which it is made.
A solar tracking collector is necessary because the position of the sun needs to be tracked for the maximum utilization of incoming solar radiation. The intensity of solar radiation varies during the day and with seasons. Tracking collectors can be divided into two categories: one axis tracking and two-axes tracking collectors.
During daytime, in the summer season, the solar collector can function as a buffer space as that reduces heat input through the building envelope or a ventilated facade with the same role. Regarding glazed solar collectors, the phenomenon is similar. Figure 3 represents a classic Trombe wall.
This type of collector is generally used in solar power plants. A trough-shaped parabolic reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station.
