ABSTRACT:
A cooling system for cooling an ambient to be cooled, a cooler and a method of controlling a cooling control system are described. The cooling control system comprises a variable capacity compressor and a controller, the controller measuring the load of the compressor by means of the measurement of the electric current and verifying the temperature condition in the cooler ambient and actuating on the cooling capacity of the compressor, the compressor being controlled to actuate in cycles, the cooling capacity being altered in function of an evolution of the load of the compressor along the cooling cycles in combination with an evolution of the temperature condition in the cooled ambient.
