Problems solved by technology

[0004] Therefore, in the method of constructing a plurality of ordinary single-loop feedback control systems, such temperature disturbance makes it difficult to stabilize the operating quantity, and it is difficult to perform good control
For example, if the temperature changes greatly when transferring to the desired air-conditioning environment, deviations will occur in the control state, and the operation will become unstable due to chaotic actions such as each feedback control system independently searching for the stable state of the entire system.

Abstract

After the commencement of air conditioning estimated control, a temperature error between a measured temperature, measured at a subject location within an air-conditioned space, and an estimated temperature at the subject location, obtained from a heat flow analysis processing portion, is compared to a tolerance range that is set in advance for the temperature error, to evaluate a switch to air conditioning feedback control for the subject location to correct the temperature error, and if air conditioning feedback control is necessary, and instruction is given by an air conditioning instructing portion to an air conditioning system 20 to start the execution of air conditioning feedback control operations with the estimated temperature at the subject location as the setting temperature.

Description

technical field [0001] The present invention relates to the air-conditioning control technology, in particular to the air-conditioning control technology for controlling the air-conditioning environment of the target place in the space by using the heat flow analysis method of the distribution system. Background technique [0002] In order to maintain the desired air-conditioned environment in the space, install air-conditioning equipment in the air-conditioned space that should be air-conditioned, and install temperature sensors at positions representing each area of ​​the air-conditioned space, and determine the air-conditioning equipment based on the output of the temperature sensor The air volume, wind direction, temperature, etc. of the conditioned air provided. [0003] On the other hand, in a large space such as an office, work efficiency is usually given priority in the arrangement of people who become heat sources, lighting, electrical equipment, etc., and the arran...
