Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

본 발명은 공기조화기의 전류제어방법에 관한 것이다.The present invention relates to a current control method of an air conditioner.

2. 발명이 해결하려고하는 기술적 과제2. The technical problem that the invention is trying to solve

운전전류가 전원브레이커의 전류용량으로 정해지는 상한치를 초과하지 않도록 제어함과 동시에 과부하 또는 중부하의 경우라도 그 상한치에 다다른 전류치로 운전할 수 있도록 한다.The operating current is controlled so as not to exceed the upper limit determined by the current capacity of the power breaker, and at the same time, it is possible to operate with a current value that is close to the upper limit even in the case of overload or heavy load.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

압축기(1)의 구동원에 사용하는 전동기(43)의 회전수를 지정하는 목표치를 입력시키고 이 전동기(43)의 회전수가 목표치와 다른때에 소정의 변화속도로 전동기(43)의 회전수를 변하시켜서 이 전동기(43)의 회전수를 목표치에 도달하도록 제어함과 동시에 공기조화기 또는 전동기(43)의 소비전력이 미리 정한 규제영역에 도달한때에 상기한 회전수를 변화시키는때의 회전수의 변화속도를 작게 변화시키거나 상기한 목표치를 내리는 것을 특징으로 한다.The target value which designates the rotation speed of the electric motor 43 used for the drive source of the compressor 1 is input, and when the rotation speed of this electric motor 43 differs from a target value, the rotation speed of the electric motor 43 is changed by a predetermined change speed. To control the rotational speed of the electric motor 43 to reach a target value, and to change the rotational speed when the power consumption of the air conditioner or the electric motor 43 reaches a predetermined control area. It is characterized in that the rate of change is made small or the target value is lowered.

4. 발명의 중요한 용도4. Important uses of the invention

허용되어 있는 전류상한치를 초과하지 않도록 제어함과 동시에 과부하시라도 상한치 빠듯한 전류치로 운전가능한 공기조화기의 전류제어방법이다.It is a current control method of an air conditioner that can be controlled with a current value that is too high even when an overload occurs while controlling not to exceed the allowable current limit.

Claims (1)

구동원에 전동기(43)를 사용한 압축기(1), 응축기, 감압장치(5), 증발기를 사용해서 냉동주기를 구비하고, 상기한 전동기(43)의 회전수를 공기조화부하에 맞게 자동조절하도록 구성하고, 공기조화기의 운전전류를 상기한 전동기(43)의 회전수를 변경해서 제어하도록한 공기조화기의 전류제어방법에 있어서, 상기한 전동기(43)의 회전수를 지정하는 목표차를 공기조화부하에 맞게 자동설정하고, 이 전동기(43)의 회전수를 목표치와 다른때에, 소정의 변화속도로 전동기(43)의 회전수를 변화시켜서, 이 전동기(43)의 회전수를 목표치에 도달시키는 제어를 행함과 동시에, 공기조화기 또는 전동기(43)의 소비전력이 미리 정해진 규제영역에 도달한때에 상기한 회전수를 변화시키는때의 회전수의 변화속도를 작게 변화시키거나 상기한 목표치를 내리는 것을 특징으로하는 공기조화기의 운전전류를 제어하는 전류제어방법.Compressor 1 using condenser, condenser, decompressor 5, and evaporator using electric motor 43 as a drive source is provided with a refrigeration cycle, and is configured to automatically adjust the rotation speed of the electric motor 43 according to the air conditioning load. In the current control method of the air conditioner in which the operating current of the air conditioner is controlled by changing the rotation speed of the electric motor 43 described above, the target difference specifying the rotation speed of the electric motor 43 is air. When the rotational speed of the electric motor 43 is different from the target value, the rotational speed of the electric motor 43 is changed at a predetermined speed, and the rotational speed of the electric motor 43 is set to the target value. At the same time as control is performed, the change speed of the rotational speed when the rotational speed is changed when the power consumption of the air conditioner or the electric motor 43 reaches a predetermined regulation area is changed small or the target value is set. Characterized by lowering Current control method of controlling the operating current of the air conditioner to. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
