Control system for air-conditioning

Abstract

Abstract PURPOSE:To make general air-conditioning condition proper by a method wherein individual weight coefficients are determined in accordance with the conditions of respective rooms and the average of loads of detected values, showing the air-conditioning conditions of respective rooms, are obtained by utilizing the weight coefficients to control an air-conditioning machine by the average value. CONSTITUTION:Respective detected values V1-Vn of respective temperature sensors TR1-TRn are inputted into third operator OP3 and the average of loads is obtained by the operation of a formula 3 while this average becomes the average value (d)u3 of temperatures of respective rooms R1-Rn. Here the weight coefficients, determined in accordance with the degree of importance, to be remarked in the control of air-conditionings of respective rooms R1-Rn, or the temperature detecting conditions of temperature sensors TR1-TRn, are shown by notations W1-Wn in the formula. The output (c) of the operator OP2 and the output (d) of the operator OP3 are inputted into the fourth operator OP4 to add them. The output (e) of the adder OP4 is inputted into the fifth operator OP5 together with a set value SP, determined in accordance with necessary air- conditioning conditions, to operate PID (proportion, integral and differential) based on both values and the result of operation is outputted as a control signal CS.
