Title:
AIR CONDITIONING SYSTEM CONTROL DEVICE, AIR CONDITIONING SYSTEM, AIR CONDITIONING CONTROL PROGRAM, AND AIR CONDITIONING SYSTEM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/152552
Kind Code:
A1
Abstract:
An air conditioning control device controls a multi-split air conditioning system so that the operating pressure of refrigerant remains constant regardless of the indoor load. This air conditioning control device controls the rotational speed of a compressor so that the operating pressure of the refrigerant reaches a predetermined target pressure, and then after this control, controls a pressure ratio, which is the ratio of the high pressure of the refrigerant to the low pressure of the refrigerant, so that compressor efficiency is at an operating point where the efficiency is improved. Thus, the air conditioning control device can reduce compressor power consumption and allow the compressor to operate more efficiently.
