CONTROL SYSTEM AND CONTROL METHOD

To provide a control system which can bring a temperature environment in a building where an air conditioner is installed close to a temperature environment achieved by an air conditioner which can perform temperature setting in a more precise manner than the air conditioner.SOLUTION: A control system 10 includes: a reception part 44 for receiving a user set temperature of an air conditioner 20 which operates targeting at a control set temperature that can be changed by a first pitch width, at a second pitch which is smaller than the first pitch width; and a first control part 42 for operating air conditioner 20 by changing the control set temperature periodically so that an average value of the control set temperature in one cycle becomes the same as the received user set temperature.SELECTED DRAWING: Figure 1 【課題】空気調和機が設置された建物内の温度環境を、当該空気調和機よりも精細な温度設定が可能な空気調和機によって実現される温度環境に近づけることができる制御システムを提供する。【解決手段】制御システム１０は、第一の刻み幅で変更可能な制御設定温度を目標として動作する空気調和機２０のユーザ設定温度を、第一の刻み幅よりも小さい第二の刻み幅で受け付ける受付部４４と、一周期における制御設定温度の平均値が、受け付けられたユーザ設定温度と同一になるように、制御設定温度を周期的に変更して空気調和機２０を運転する第一制御部４２とを備える。【選択図】図１
