New ideas for energy utilisation in combined heat and power with cooling: I. Principles

New ideas are needed to reduce installed cooling capacities and growing ventilation costs and to improve control in the various zones of CHP plants with cooling. Above all the thermal energy available in summer from electricity cogeneration must be exploited. Unconventional cooling systems, such as evaporative or chemical dehumidification, allow one to achieve some of the objectives. Chemical dehumidification, both by adsorption and absorption, particularly permits new plant lay-outs, leading to the complete elimination of traditional cooling equipment with direct air treatment and very high potential energy savings.
