Abstract

The heat recuperator arrangement for an air circulation system with a heat exchanger (1) around an inlet duct (5) and another exchanger (2) around an exhaust duct (6), and with liquid pumped through the tubes connecting them, included an auxiliary heat exchanger (7) following the first exchanger around the inlet duct, interconnected by a valve arrangement (11, 12, 17) and a further heat exchanger (9) in the fluid circulation system, operated in an alternating manner so that during external low temperature conditions, it can be allowed to form on the exchanger on the discharge duct, then the flow is reversed so that the ice is melted.
