Advantages of a solar air collector system in general
• Air is for free.
• Air cannot freeze.
• No deterioration of the heat-transfer-fluid.
• No high pressure thrusts during a stagnation situation.
• No costs for secure systems, e. g. safety valves, membrane expansion vessels.
• No environmental or security problems in case of system leakages.
• Collector is intrinsically safe to itself and to the system.
• Solar air collectors enable easy and cost-effective highly scaleable solar thermal collector fields.
Disadvantages of a solar air collector in general
• Air has a lower heat capacity than water.
• Movement of air can cause aerodynamic noises.
• To achieve the same mass flow of air then of water, you need more electrical energy for the fan than for a water pump.
