Title:
REFRIGERANT CYCLE SYSTEM
Document Type and Number:
Japanese Patent JP2020201008
Kind Code:
A
Abstract:
To solve a problem that in some cases, it is preferable to enable connection of a larger number of use side units to one heat source side unit.SOLUTION: A refrigerant cycle system 100 includes a first refrigerant circuit 1, a second refrigerant circuit 2, a third refrigerant circuit 3, a first cascade heat exchanger 21a, a second cascade heat exchanger 41a, a first flow regulating valve 22 and a second flow regulating valve 42. The first cascade heat exchanger 21a exchanges heat between a first refrigerant and a second refrigerant. The second cascade heat exchanger 41a exchanges heat between the first refrigerant and a third refrigerant. The first flow regulating valve 22 regulates the amount of the first refrigerant flowing into the first cascade heat exchanger 21a in the first refrigerant circuit 1. The second flow regulating valve 42 regulates the amount of the first refrigerant flowing into the second cascade heat exchanger 41a in the first refrigerant circuit 1. The first cascade heat exchanger 21a and the second cascade heat exchanger 41a are connected in parallel in the first refrigerant circuit 1.SELECTED DRAWING: Figure 1
