摘要:
A system including a photovoltaic panel having a first heat exchanger for absorbing heat from the panel and/or from the environment by a heat exchanging fluid, connected to a heat pump. A second heat exchanger is provided for absorbing heat by the heat exchanging fluid and a control means for controlling a flow of the heat exchanging fluid through the first heat exchanger and/or the second heat exchanger. The heat pump is arranged to cool the heat exchanging fluid. The system has the following operating modes: a first mode in which cooled heat exchanging fluid is fed to the first heat exchanger; and a second mode in which cooled heat exchanging fluid is fed to the second heat exchanger and then fed to the first heat exchanger.

An apparatus for heating a working fluid of a gas turbine-solar power generation system, comprising, sequentially connected, a cold air flow channel, a heat collecting cavity, and a hot air passage. The hot air passage is formed by connecting an inner housing on the front side to a supplemental heating section on the rear side. Also comprised is a burner for heating a primary heating air within the supplemental heating section when having insufficient solar power, and the burner is arranged at the supplemental heating section.

According to various aspects, exemplary embodiments are disclosed of solar thermal collectors, solar heating systems, and thin plate heat exchangers and absorbers. The thin plate heat exchangers and absorbers may be used for solar applications and/or non-solar applications. In an exemplary embodiment, a solar thermal collector generally includes a first layer comprising polymer and configured to allow sunlight to pass therethrough. A second layer comprises polymer and is configured to absorb thermal energy from sunlight. The second layer includes edges heat sealed to edges of the first layer. A permeable core is disposed between the first and second layers. In operation, a heat transfer fluid may flow through the permeable core and directly contact the second layer, whereby thermal energy is transferrable from the permeable core and the second layer to the heat transfer fluid.
