METHOD OF CONTROLLING OPERATION OF VARIABLE CAPACITY COMPRESSOR IN COOLER

PURPOSE:To facilitate adjustment of room temperature and prevent any loss of power by changing over capacity of a variable capacity compressor to adjust a damper operating control lever to a predetermined position at first when temperature in a room to be cooled reaches a set temperature.

Zusammenfassung:	PURPOSE:To facilitate adjustment of room temperature and prevent any loss of power by changing over capacity of a variable capacity compressor to adjust a damper operating control lever to a predetermined position at first when temperature in a room to be cooled reaches a set temperature. CONSTITUTION:When a compressor 2 has been changed over from 100% to 50% rate of operation, causing shortage of present cooling ability, vehicle room temperature T rises and reaches a set temperature T1(25 deg.C) so that capacity increasing signal is generated from a controller 16 to change over the compressor from 50% to 100% rate of operation. When thus the cooling ability is increased and the temperature T in the vehicle room is again lowered to a set temperature T2(23 deg.C), the compressor is changed over from 100% to 50% rate of operation. Then similarly the capacity is changed over from 50% to 100% or vice versa alternatively. Thus, useless heating of overcooled air is obviated to provide efficient operation of the compressor.
