Abstract

It is a system that uses the air heated during the process of condensation of the refrigerant in condenser units (1) belonging to refrigerating circuits of open refrigerating cabinets (2) of stores where different foods are sold.
The system includes means to adequately channel the heated air, mainly towards the inside of the establishment in winter and towards the outside in summer.
Conventionally, at best, the air heated by the condenser units (1) always flows towards the inside of the store. In other cases, this air is expelled to the outside when the condenser units (1) are located outside the establishment.
In any case, means to adequately channel this stream of heated air for the use thereof as in the case of the invention in question have not been provided for.
