Abstract (en)
The installation has a condenser (2) with a bypass (5) that passes gas towards liquid coolant reservoir (3). Controlled valves (4a, 4b) are arranged on a main duct between the bypass and the condenser, where the bypass has other controlled valves (5a, 5b). An anti-return valve (6) is arranged between an outlet of the condenser and a liquid cooling injection (9). The valves (4a, 4b, 5a, 5b) permit to automatically and continuously regulate condensation pressure of coolant fluid and pressure of the fluid in downstream of the condenser following sub-cooling.
Abstract (fr)
La présente invention se rapporte à une installation de réfrigération caractérisée en ce qu'elle comprend des moyens de réguler de façon distincte, continue et automatique (4A,4B ;5,5A,5B), d'une part, la pression de condensation du fluide réfrigérant et d'autre part, la pression de celui-ci en aval du condenseur (2), et par suite le sous-refroidissement.
