Fuzzy control of branch flow rate and combustion of a multi-type absorption type air conditioner and its method

摘要

The present invention relates to an apparatus and method for fuzzy control of branch flow rate and combustion of a multi-type absorption type air conditioner that automatically controls a system by determining an operation state of an outdoor unit according to each indoor load.;Conventional multi-type absorption type air conditioners have a problem in that it is difficult to adapt to various changes of the indoor environment because they are operated only in one designated cycle by the on-off control method.;In addition, since the main indoor unit rely solely on different temperature conditions to operate the system, it is very difficult for a plurality of indoor units to operate under different temperature conditions, and it is inefficient. In addition, There has been a problem of troublesome operation such as manual control of the flow rate to each indoor unit and variation of the amount of combustion heat input.;In order to solve this problem, the present invention is characterized in that the first and second indoor temperature sensing units for sensing the indoor temperature of the respective indoor units, and the indoor temperature obtained from the first and second indoor temperature sensing units are compared with the temperatures set by the user, The first and second indoor unit microcomputers output the comparison result. The outdoor unit determines the burner heat input by calculating the temperatures output from the first and second indoor unit microcomputers, and controls the combustion and flow control valves according to the determined amount of heat input. And a microcomputer.
