Abstract
(EN)
The present invention provides a gas discharge device for discharging non-condensable gas in a refrigeration and air conditioning system, and a method thereof. The gas discharge device comprises an evaporative condenser, which isolates liquid refrigerant and non-condensable gas by condensing a gas mixture of gaseous refrigerant and non-condensable gas exiting the refrigeration and air conditioning system, and leads the isolated liquid refrigerant into the refrigeration and air conditioning system, but discharges the isolated non-condensable gas. The method comprises an evaporative condensation process, a gas discharge process and a liquid discharge process. The present invention can prevent the accumulation of non-condensable gas in a condenser of a refrigeration and air conditioning system, and thereby helps to guarantee the refrigerating capacity and energy efficiency of the refrigeration and air conditioning system, such that it operates safely and efficiently.

La présente invention concerne un dispositif d'évacuation de gaz permettant d'évacuer un gaz non condensable dans un système de réfrigération et de climatisation, et un procédé associé. Le dispositif d'évacuation de gaz comprend un condenseur évaporatif, qui isole un fluide frigorigène liquide et un gaz non condensable par condensation d'un mélange gazeux de fluide frigorigène gazeux et de gaz non condensable sortant du système de réfrigération et de climatisation, et conduit le fluide frigorigène liquide isolé dans le système de réfrigération et de climatisation, mais évacue le gaz non condensable isolé. Le procédé comprend un processus de condensation par évaporation, un processus d'évacuation de gaz et un processus d'évacuation de liquide. La présente invention peut empêcher l'accumulation de gaz non condensable dans un condenseur d'un système de réfrigération et de climatisation, et contribue ainsi à garantir la capacité de réfrigération et l'efficacité énergétique du système de réfrigération et de climatisation, de telle sorte que ce dernier fonctionne de manière sûre et efficace.
