  • Chilling unit with “free-cooling”, designed to operate also with variable flow rate; system and process
    Patent number: 6640561
    Abstract: A unit comprises a refrigerating circuit (30), at least part of a primary circuit (110), and connections (151, 152) for a user's circuit (120). The refrigerating circuit comprises an evaporator (E), a compressor (31), a condenser battery (C), and an expansion valve (34), and connection lines. The primary circuit extends through the evaporator and through an air-cooled “free-cooling” battery (FC). To allow a variable flow through the free-cooling battery, though maintaining the flow rate constant through the evaporator, the primary circuit (110) comprises a bypass line (140) extending between an outlet line from the evaporator and an inlet line to the evaporator, and a storage tank (A) on said bypass line.
