AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/139758
Kind Code:
A1
Abstract:
An air conditioner (1000) comprises a refrigerant, a refrigerant circuit (500), a heat exchanger (250), and a control device (100). The refrigerant circuit (500) includes at least a compressor (200), a condenser (210), and an evaporator (110) and circulates the refrigerant therethrough. The heat exchanger (250) has a first flow path (R1) through which the refrigerant that has passed through the condenser (210) flows and a second flow path (R2) through which the refrigerant to be sucked into the compressor (200) flows, and exchanges heat between the refrigerant passing through the first flow path (R1) and the refrigerant passing through the second flow path (R2). The control device (100) controls the refrigerant circuit (500) so that the superheat of the refrigerant flowing through the outlet of the evaporator (110) is 5°C or lower.
