Claims (3)

  1. 주파수 제어에 의한 속도가 가변인 압축기 전동기를 구비하고, 또한 온도편차검출수단에 의해 복수의 공기조화해야 할 목표실온(室溫)을 실제의 실온과의 온도편차로서 검출하고, 상기 온도편차에 따른 속도 지령을 발생해서 전동기의 속도를 제어하는 멀티 냉동사이클에 있어서, 냉동사이클중의 부하를 검출하는 센서와, 이 센서로 부터의 검출출력이 미리 설정된 소정의 폭내에 있는지를 판정 예측하는 동시에 그 예측치가 상기 소정치 이하일때 상기 속도 지령에 대한 주파수를 증가 보정하고, 또한 상기 예측치가 상기 소정치 폭을 초과했을때 상기 속도지령에 대한 주파수를 감소 보정하도록 제어하는 제어수단을 구비하여 이루어진 멀티 냉동사이클의 주파수 제어장치.
  2. 제 1 항에 있어서, 센서로서 전동기의 1차전류를 검출하는 전류센서를 사용하는 것을 특징으로 하는 멀티냉동사이클의 주파수 제어장치.
  3. 제 1 항에 있어서, 센서로서 압축기의 토출측 압력을 검출하는 압력센서를 사용한 것을 특징으로 하는 멀티 냉동사이클의 주파수 제어장치.
