Air conditioning system with waste heat recovery - has heat exchangers in air vent and outside air conduits linked with refrigerating compressor

摘要

The air conditioning system has heat exchangers to recover waste air heat. Both the waste air vent conduit and the outside air conduit have fitted coolant air heat exchangers which are linked by a reversible flow coolant circuit with a refrigerating compressor. The exchangers are finned tubes with a small pressure gradient on the air side. The compressor forms a single unit together with the outside air heat exchanger and air treatment components such as the weather grid, feed air filter and fan preheater.
