The invention relates to a process for the production of cold with interposed cold reservoir for the supply of ventilating plants or the like with cold water and a plant for the performance of the process. This process is characterised in that a primary circulation, with a cold reservoir constructed as a water reservoir with partial ice formation, and a secondary circulation, in heat exchange with the first circulation and with at least one heat exchanger on the consumer side, are used. a) a water reservoir with an integrated ice reservoir being used, and the heated return water of the primary circulation, introduced into the water reservoir with partial ice formation, flowing through the water reservoir by forced flow via bypasses, and being taken in again from the water reservoir as feed water of the primary circulation, b) the pumps in the primary circulation conducting the low tempered cold water being controlled and switched by the feed and return temperatures, controlled by the external temperature, in the secondary circulation, with simultaneous maximum limiting of the return temperature of the primary circulation, and c) by regulation of the cold water flow in the secondary circulation while maintaining a minimum quantity of circulation to obtain the control parameters for the secondary and primary circulation pumps, the pumps in the secondary circulation being controlled by the differential pressure required for the heat exchanger(s) on the consumer side. s
