Title
(EN) Method and arrangement for conveying heat from exhaust air into inlet air by a heat exchanger via which non-freezing heat transfer liquid is circulated
Abstract
(EN)
The invention relates to a method and arrangement for conveying heat, in which heating or cooling capacity is conveyed from the exhaust air (B-B') of ventilation or air conditioning of standard rooms into inlet air (A-A') by means of an inlet air heat exchanger, via which non-freezing heat transfer liquid is circulated. For reducing the investment costs, the non-freezing heat transfer liquid is brought into direct contact with the exhaust air (B-B').
