Title:
AIR CONDITIONING SYSTEM CONTROL DEVICE, OUTDOOR UNIT, RELAY DEVICE, HEAT SOURCE DEVICE, AND AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/193686
Kind Code:
A1
Abstract:
The purpose of the present invention is to cause air conditioning capacity in an indirect-type air conditioning system using water, brine, or the like to quickly respond to changes in indoor load. An air conditioning device (1) has a first mode and a second mode as operation modes. In the first mode, the amount that a first flow rate regulating valve (33) is opened is fixed to a first opening that is between 0% and 100% (exclusive), and the operating frequency of a compressor (11) varies in accordance with the air conditioning capacity demanded from a third heat exchanger (31). In the second mode, the amount that the first flow rate regulating valve (33) is opened varies in accordance with the air conditioning capacity demanded from the third heat exchanger (31). The operation mode changes from the first mode to the second mode when the difference between the air conditioning capacity demanded from the third heat exchanger (31) and the air conditioning capacity demonstrated by the third heat exchanger (31) increases higher than a determined value.
