Document Type and Number:
Japanese Patent JP2016090180
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To add a new operational function to an air-conditioning system while suppressing a cost increase.SOLUTION: A liquid coolant passage (PR1) is connected to a liquid end of an outdoor unit (20) and a liquid end of an indoor unit (30). A gas coolant passage (PR2) is connected to a gas end of the outdoor unit (20) and a gas end of the indoor unit (30). A bypass coolant passage (PR3) is connected to the liquid coolant passage (PR1) and the gas coolant passage (PR2). A coolant/water heat exchanger (41) exchanges heat between a coolant flowing in a bypass coolant passage (PR3) and water flowing in a water passage (PW). An opening/closing valve (42) is provided in the liquid coolant passage (PR1), and is disposed between a contact point of the liquid coolant passage (PR1) and the bypass coolant passage (PR3) and the liquid end of the indoor unit (30). A flow rate adjusting valve (43) is provided in the bypass coolant passage (PR3), and is disposed between the contact point of the liquid coolant passage (PR1) and the bypass coolant passage (PR3) and the coolant/water heat exchanger (41).SELECTED DRAWING: Figure 1
