Definitions
- the present invention in a refrigeration system using a non-azeotropic refrigerant mixture, has a large scale, particularly in a freezer warehouse, and therefore requires a large capacity for starting up to a predetermined freezer temperature or
- the present invention relates to a freezer for a freezer having a large fluctuation in the internal temperature due to the necessity of opening the door widely when taking in and out the contents.
- Patent Document 1 Japanese Patent Laid-Open No. 11 99498
- Freezer structure Prefabricated structure with double doors
- Compressor discharge Compressor suction Heat exchanger Heat exchanger Operation
- Compressor discharge Compressor suction
- the inner wall of the container and the storage in the frozen state are already at the set temperature.
- the greatly elevated interior atmosphere and new contents are subject to cooling. Therefore, the cooling load from the viewpoint of heat capacity is relatively small, but the cooling temperature range is large, and the refrigeration system of the present invention that has a quick response to the temperature change in the refrigerator has the contents in such a freezer. It is possible to quickly return to the steady operating temperature with respect to temperature changes caused by taking in and out, etc., and it is also suitable for the actual usage of the freezer.

Abstract
L'invention permet d'améliorer les performances initiales d’excursion d’une machine réfrigérante employant un réfrigérant non azéotrope immédiatement après le démarrage lorsque la température de la chambre est élevée. L'invention concerne donc une machine réfrigérante à un seul niveau employant un réfrigérant non azéotrope et possédant un compresseur (1), un condenseur (2), et un évaporateur (10), et dans laquelle l’échange thermique (3) réalisé entre le réfrigérant retourné de l’évaporateur et le réfrigérant haute pression s’écoulant du condenseur vers l’évaporateur est contrôlé de la manière suivante. Si une charge importante est imposée comme c'est le cas juste après le démarrage, des tubes capillaires (6-1) à (6-5) faisant office de valves de dilatation pour l’évaporateur sont grands ouverts avec des valves électromagnétiques (5-1) à (5-5). Tandis que la température interne de la chambre décline, les tubes sont fermés de manière successive. Ainsi, la pression et le débit du gaz réfrigérant sont régulés. Si la température interne de la chambre est élevée et la condensation d’un ingrédient à faible point d’ébullition ne se déroule pas, la capacité réfrigérante d’un réfrigérant à haut point d’ébullition peut devenir maximale.
