Abstract

Des systèmes de réfrigération transcritiques R-744 pour des supermarchés comprennent une capacité de déshumidification, la chaleur du R-744 sortant du refroidisseur de gaz étant utilisée pour la déshumidification. Le même échangeur de chaleur est utilisé aux fins de récupération de chaleur et de déshumidification.
