Abstract:
A method for controlling a corresponding energy supply of a heat source unit of a refrigeration air conditioning system based on a required energy value calculated from an output power value, comprising the steps of:(1) inputting a detected power value from an output power detection unit and transferring the power value to a central micro processing unit for converting the power value to a refrigeration air conditioning required energy value, a setting value, and a deviation value, and feeding the refrigeration air conditioning required energy value to an air conditioning required energy value calculation unit; and (2) selecting an operation type categorized as a single unit, a single region or a multi-region, and the air conditioning required energy value calculation unit calculating a total refrigeration air conditioning required energy value which is transferred to a heat source unit controller to control a heat source supply under the following conditions: I. when the total refrigeration air conditioning required energy value is greater than the setting value and the deviation value, controlling the heat source unit to provide maximum amount of the heat source supply; II. when the total refrigeration air conditioning required energy value is greater than the setting value but less than the sum of the setting value and the deviation value, controlling the heat source unit to provide the heat source supply in a directly proportional relationship with the refrigeration air conditioning required energy value such that supplied refrigeration air conditioning power is equivalent to refrigeration air conditioning loading; and III. when the total refrigeration air conditioning required energy value is less than the setting value, controlling the heat source unit to provide a minimum amount of the heat source supply.
