Résumé

Absorption refrigerating machines represent an interesting alternative to compression machines, especially when waste heat or heat produced by solar energy is available; the market is beginning to propose small-size absorption machines especially designed for air conditioning in residential buildings. A survey of small-size absorption refrigerators is presented, with particular emphasis on their performance when the heat source comes from solar energy. The machines examined cover a range of chilling powers (4 to 15 kW) and have different working principles. The study is conducted using data supplied by manufacturers and collected in an experimental set-up realized by the University of Perugia; different refrigerators are compared taking into account the most significant parameters, such as heat source and chilled water temperature, cooling circuit characteristics, coefficient of performance, dimensions and weight. Energy and environmental advantages deriving from the solar supply are also evaluated.
