This paper analyses a new indirect evaporative cooling system characterized by low energy demand for use in summer conditions. The process is carried out by means of a membrane contactor equipped with a hydrophobic membrane that is permeable to vapour but not to the liquid phase. Chilled water feeds a radiant ceiling panel in order to reduce the mean radiant and indoor air temperatures in the environment served, thereby improving indoor comfort conditions. The results yielded by a Simulink program in different summer climatic conditions in the Mediterranean area show that indoor comfort conditions can be limited to PMV 0.7 for most of the time.

Abstract
This paper analyses a new indirect evaporative cooling system characterized by low energy demand for use in summer conditions. The process is carried out by means of a membrane contactor equipped with a hydrophobic membrane that is permeable to vapour but not to the liquid phase. Chilled water feeds a radiant ceiling panel in order to reduce the mean radiant and indoor air temperatures in the environment served, thereby improving indoor comfort conditions. The results yielded by a Simulink program in different summer climatic conditions in the Mediterranean area show that indoor comfort conditions can be limited to PMV 0.7 for most of the time.
