FIELD: heating. ^ SUBSTANCE: cooling system includes many compressors, the first condensation unit having the first control unit and at least one additional condensation unit having additional control unit. Each condensation unit has at least one compressor of the above multiple compressors. Communication line is connected to the first control module and at least to one additional control module. The first control unit controls multiple compressors on the basis of communication with at least one additional control module through communication line. As per the other version, cooling system includes condenser with multiple condenser fans with variable speed, pressure sensor at the outlet of the above condenser and control unit which controls multiple condenser fans on the basis of the above comparison. Control module determines the fan speed for each of the condenser fans, increases the fan speed, which operates at lower speed when outlet pressure signal is higher than the specified value, and decreases the speed of the fan operating at higher speed when outlet pressure signal is smaller than the specified value. ^ EFFECT: increasing efficiency. ^ 20 cl, 4 dwg |
