Document Type and Number:
Japanese Patent JP2902061
Kind Code:
B2
Abstract:
PURPOSE:To reduce the number of starting revolutions of a compressor through utilization of inertia of a load and to improve reliability by a method wherein the working frequency of the compressor is decided based on a total sum of operation control points weighted by means of a temperature difference between the temperature of each part to be air-conditioned and a set temperature. CONSTITUTION:An operation control point P allotted by means of a difference between the temperature of each part to be air-conditioned and a set temperature is set. The working frequency of a compressor responding to a total sum thereof is commanded to an outdoor machine l. An operation set point at which the compressor is started to run is 2 or more in a total. When, for example, four rooms are an object to be air-conditioned, the operation control point of each of at least two rooms is one point. Since operation is started when a room temperature is not reduced to a value too low for the starting of running of the compressor, controllability of a room temperature is excellent. Further, since it takes ten or more minutes starting from the stop of the compressor that a total sum of operation control points amounts for two points, the number of running and stopping times of the compressor is reduced through utilization of inertia of a load by a plurality of parts to be air-conditioned, and reliability of the compressor is improved.
