Absorption Refrigeration
In solar thermal absorption refrigeration technology, the chiller is used to absorb heat from the tank attached to the solar collector. According to the solution regeneration and thermal operation cycle, the absorption systems can be divided into three categories: single-effect, half-effect and double-effect solar absorption cycles.
