Title:
CONTROL DEVICE OF MULTIPLE AIR CONDITIONING DEVICE, MULTIPLE AIR CONDITIONING DEVICE INCLUDING THE SAME, AND ITS CONTROL METHOD AND CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP2018204897
Kind Code:
A
Abstract:
To suppress sudden increase of a refrigerant discharge temperature of a compressor in switching the number of operated indoor units.SOLUTION: A control device of a multiple air conditioning device includes a determination portion 52 for determining whether a ratio of a compressor rotating speed command value before switching an operation, to a compressor rotating speed command value as a command value of the rotating speed of the compressor after switching the operation is over a first prescribed multiple or not when the operations of the indoor units are switched within a prescribed period, and a rate setting portion 53 for setting a falling rate of the rotating speed of the compressor to a falling rate of the rotating speed of the compressor in a case when the ratio is not over the first prescribed multiple, when the ratio is over the first prescribed multiple.SELECTED DRAWING: Figure 2
