Brief description of the cooling cryogenic of constructing a coupling between the system cryogenic of a tunnel and a cooling system was added to the tunnel through a condenser packaging

摘要

The present invention relates to a cooling installation or cryogenic deep-freezing of products, including a cryogenic tunnel, characterized in that: - there is a heat exchanger / condenser outside the tunnel, in which it conveys the whole or part of the cold gases resulting from the vaporization of the cryogenic fluid carried out in the tunnel, allowing these gases to give to the condenser at least a part of their frigories, before being discharged toward the outside; - is placed inside the tunnel, preferably in its zone of the input of a heat exchanger / cold battery, cold battery involved in the construction, with said condenser, a system for the production of cold mechanical.
