行なえるのでこの説明は省略する。As means for changing this capacity, capacity control using a plurality of compressors or capacity control by changing the rotation speed of the compressors has been considered. However, the control device is different depending on, for example, when three compressors are used and when five compressors are used. Therefore, when designing an air conditioner, it was necessary to design each air conditioner according to the number of compressors. In this way, efficient operation can be achieved by individually setting the set values such as the number of compressors according to the installation conditions. In addition, when controlling the temperature of multiple rooms using water piping and fan coil units connected to the water piping, the air conditioner must be adjusted according to the standards for changing the operating capacity due to changes in the air conditioning load, the length of the water piping, and the heat dissipation (heating) of the water. At the time of design, water temperature settings that take into account heat absorption (when cooling) or heat absorption (when cooling), differential temperature range for operation control, etc. were set individually according to the installation conditions at the time of design. Furthermore, if the operating capacity of the air conditioner can be changed, for example, if a compressor that can change the capacity in multiple stages is used, or if a compressor that can change the capacity by changing the rotation speed is used, multiple air conditioners When a harmonizer unit is provided and the operating capacity is changed by changing the number of operating units, the standard for changing the operating capacity can only be set at the time of design. Therefore, it was necessary to design a control device individually for each different setting condition. Incidentally, the operation of the air conditioner based on the set value of the air conditioning capacity can be carried out by conventional operation control, so a description thereof will be omitted.
