Heat recovery system which is intended for air-conditioning and to reduce the cold corridor effect

Improved heat recovery system which is intended for air-conditioning and to reduce the cold corridor effect, comprising

• a heat recovery and exploitation unit;
• and
• a unit for distributing and supplying the heated air via the lower part of an open retail refrigeration cabinet or lines of same;
• said units located in the interior of a retail outlet or a large retail store or an area to be air-conditioned for the display, distribution and/or sale of perishable food products, which is used to mitigate the effect known as cold corridor;
• characterised in that
• the unit for distributing and supplying the heated air (1) comprises means for extracting an airflow from the interior of the corridor via the upper part thereof through some grilles (2) and for pumping the airflow via at least one compact heat exchanger (6) which is housed in the airflow entrance;
• where the air temperature is increased prior to introducing the flow of heated air into a duct (4) housed in the rear part of an open retail refrigeration cabinet or lines of same, which is then pulsed via the lower part of the refrigeration cabinet.
