Abstract

The invention relates to a device and a method for pre-cooling brewing liquor using a refrigeration device, the said refrigeration device being designed as an absorption-type refrigeration device, and preferably as a LiBr absorption-type refrigeration device, with an evaporator, an absorber, a generator and a condenser, and the generator being operated with surplus process heat produced in the brewery. Use is preferably made of the water vapour heat which is recovered in the copper vapour condenser and which can be subjected to intermediate storage in an energy reservoir.
