Title:
REFRIGERATION CYCLE SYSTEM, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/040274
Kind Code:
A1
Abstract:
A refrigeration cycle system and an air conditioner, the refrigeration cycle system comprising: a heat exchanger (100); and a one-way valve (300) provided in the heat exchanger (100), the one-way valve (300) satisfying the following relationship: L3 * R ≤ Z1, wherein L3 is the diameter of a throat portion of a valve body of the one-way valve (300), the unit thereof being in cm; R is the equivalent radius of a valve core (340) of the one-way valve (300), the unit thereof being in cm; and Z1 is a set value. By means of the size design of the one-way valve (300) selected by the refrigeration cycle system, the valve core (340) can match a difference in pressure applied to an inlet and an outlet of the one-way valve (300) during operation of the refrigeration cycle system, so that the one-way valve (300) can still work normally under a small pressure difference.
