(EN) STARTUP LOGIC FOR REFRIGERATION SYSTEM
(FR) LOGIQUE DE DÉMARRAGE POUR SYSTÈME DE RÉFRIGÉRATION
Abstract
(EN)
A refrigeration system (10) includes a compressor (20) having a first stage (20a) and a second stage (20b); a heat rejecting heat exchanger (40) having a fan (44) drawing ambient fluid over the heat rejecting heat exchanger, the heat rejecting heat exchanger including an inter- cooler (43) and a gas cooler(41), the intercooler coupled to an outlet of the first stage and the gas cooler coupled to an outlet of the second stage;, an unload valve (93) coupled to an outlet of the intercooler and a suction port of the first stage; a flash tank (70) coupled to an outlet of the gas cooler; a primary expansion device (55) coupled to an outlet of the flash tank; a heat absorbing heat exchanger (50) coupled to an outlet of the primary expansion device, an outlet of the heat absorbing heat exchanger coupled to the suction port of the first stage; and a controller (100) for executing a startup process.

(FR)
L'invention porte sur un système de réfrigération qui comprend un compresseur (20) ayant un premier étage (20a) et un second étage (20b) ; un échangeur de chaleur de rejet de la chaleur équipé d'un ventilateur (44) qui aspire le fluide ambiant en le faisant passer sur l'échangeur de chaleur de rejet de la chaleur, l'échangeur de chaleur de rejet de la chaleur comprenant un refroidisseur intermédiaire (13) et un refroidisseur de gaz, le refroidisseur intermédiaire étant raccordé à une sortie du premier étage et le refroidisseur de gaz (41) étant raccordé à une sortie du second étage ; une soupape de décharge (92) raccordée à une sortie du refroidisseur intermédiaire et à un orifice d'aspiration du premier étage ; un réservoir de vaporisation sous vide (70) raccordé à une sortie du refroidisseur de gaz ; un dispositif de détente principal (55) raccordé à une sortie du réservoir de vaporisation sous vide ; une sortie de l'échangeur de chaleur d'absorption de la chaleur (50) raccordée à l'orifice d'aspiration du premier étage ; et une unité de commande (100) servant à exécuter un processus de démarrage.
