Abstract:
(EN) This refrigerating machine is equipped with: a turbocompressor which compresses a refrigerant; a condenser which is equipped with one or more pipe groups (31) configured from a plurality of heat transfer pipes (30) through which cooling water flows, and condenses the refrigerant compressed by the turbocompressor; an expansion valve which causes the refrigerant condensed by the condenser (4) to expand; an evaporator which causes the refrigerant expanded by the expansion valve to evaporate; a temperature sensor (37) which detects cooling water exit temperature, which is the temperature of the cooling water flowing from at least one of the heat transfer pipes (30) constituting the pipe group(s) (31); and a control unit which determines, on the basis of the detection temperature of the temperature sensor (37), air bleeding start conditions for starting an air bleeding operation to bleed and discharge air to the outside.
(FR) La présente invention concerne une machine frigorifique comprenant : un turbocompresseur destiné à comprimer un réfrigérant; un condenseur muni d'un ou de plusieurs groupes de tuyaux (31) conçus à partir d'une pluralité de tuyaux de transfert de chaleur (30) à travers lesquels s'écoule de l'eau de refroidissement, et destiné à condenser le réfrigérant comprimé par le turbocompresseur; un détendeur destiné à amener le réfrigérant condensé par le condenseur (4) à se détendre; un évaporateur destiné à amener le fluide réfrigérant détendu par le détendeur à s'évaporer; un capteur de température (37) destiné à détecter la température de sortie de l'eau de refroidissement, c'est à dire la température de l'eau de refroidissement coulant à partir d'au moins l'un des tuyaux de transfert de chaleur (30) constituant le ou les groupes de tuyaux (31); et une unité de commande destiné à déterminer, sur la base de la température de détection du capteur de température (37), les conditions de démarrage de purge d'air pour démarrer une manœuvre de purge d'air afin de purger et d'évacuer l'air vers l'extérieur.
(JA) 冷媒を圧縮するターボ圧縮機と、冷却水が流れる複数の伝熱管(30)から構成される管群(31)を1つ以上備え、ターボ圧縮機にて圧縮された冷媒を凝縮させる凝縮器(4)と、凝縮器(4)にて凝縮された冷媒を膨張させる膨張弁と、膨張弁にて膨張された冷媒を蒸発させる蒸発器と、管群(31)を構成する少なくとも1つの前記伝熱管(30)から流出する冷却水の温度である冷却水出口温度を検出する温度センサ(37)と、温度センサ(37)の検出温度に基づいて、空気を外部へと抽気する抽気動作を開始する抽気開始状態を判断する制御部とを備えている。
