Abstract
Method for operating a "compound" refrigerating plant which alternately runs through cooling and defrosting phases, comprising a refrigerant circuit (cycle), a compressor, a condenser, a throttling (expansion) valve and an evaporator via which the cooling of the cooling agent (nonfreezing solution, secondary fluid) circulating in a cooling agent circuit is performed. After the cooling agent is cooled it is fed to one or more air (unit) (coolers) (air cooling batteries) arranged in parallel and subsequently fed again to the evaporator by means of a pump. At least a portion of the cooling agent is heated during the cooling phase in indirect heat exchange or, by means of a further cooling agent circuit arranged between the refrigerant and cooling agent circuits, by the refrigerant, which is superheated during the cooling phase in the compressor. After termination of the cooling phase, the cooling agent heated in this way circulates for the purpose of defrosting the air coolers in the cooling agent circuit.
