Document Type and Number:
WIPO Patent Application WO/2023/058084
Kind Code:
A1
Abstract:
Provided is an air-conditioning system which constantly flows cold/hot water to prevent freezing. An air conditioning system (10) comprising: a heat source device (4) that heats or cools water to produce cold/hot water; an air conditioner (12) that exchanges heat between the cold/hot water and air; a cold/hot water supply circuit (11) that supplies the cold/hot water to the air conditioner (12); and a control device (50) that circulates the cold/hot water in the cold/hot water supply circuit (11) so that the cold/hot water does not freeze while the air conditioner (12) is stopped. The cold/hot water supply circuit (11) has a flow rate adjustment valve (13) that adjusts the amount of cold/hot water circulating, and a fluid detector (14) that detects whether cold/hot water is flowing. When circulating cold/hot water so that the cold/hot water does not freeze while the air conditioner (12) is stopped, the controller (50) increases the opening of the flow rate adjustment valve (13) if it is detected by the fluid detector (14) that no cold/hot water is flowing.
