Apparatus for controlling operation of outdoor unit and its method

A method for controlling an operation of compressor/condenser unit, the method comprising:

• sensing a pressure of refrigerants in an outlet of a compressor of the compressor/condenser unit;
• sensing a temperature of the refrigerants in an outlet of a condenser;
• comparing the sensed pressure and temperature with optimal pressure and temperature ranges;
• when the pressure and temperature exist within the optimal pressure and temperature ranges, maintaining the current operation conditions of a blast fan and the compressor of the compressor/condenser unit;
• when the pressure and temperature are lower than the optimal pressure and temperature ranges, increasing a revolution number of the blast fan by a predetermined value, and decreasing an operation frequency of the compressor by a predetermined value;
• and
• when the pressure and temperature are higher than the optimal pressure and temperature ranges, decreasing the revolution number of the blast fan by a predetermined value, and increasing the operation frequency of the compressor by a predetermined value.
