コンテナ用冷凍ユニット

Refrigeration apparatus for container

Abstract

(57)【要約】 【目的】 圧縮機1の停止中に蒸発器用送風機5を運転 することによってその駆動エネルギが無駄に消費される のを防止し、かつ、コンテナ内空気が加熱されるのを阻 止する。 【構成】 冷凍モード運転時に圧縮機1のオン・オフに 連動して蒸発器用送風機5をオン・オフさせる。
PURPOSE: To economize in power expended on the blower for the evaporator when the compressor is turned off and prevent the blower for the evaporator from sending heat into the air in the storage chamber by timing the off-and-on control of the blower for the evaporator to the off-and-on control of the compressor during operation in the refrigeration mode. CONSTITUTION: The temperature for the storage chamber set by a means 15 is inputted to a means 21 in a controller 20; at the means 21 this input is compared with a specified value inputted from a means 22 and according as the set temperature is above or below the specified value a decision is made as to which of cold storage mode and freeze mode is to be used for the operation. The result of this decision is stored in a means 25. On the other hand, the temperature of the storage chamber of the container 6 is detected by a sensor 9 and inputted to a means 23 to be compared with the set temperature. The result of the comparison at the means 23 is inputted to a means 24 where the turning on and off of the operation is decided in conformity to rules and a map corresponding to the operation mode inputted from the means 25. In other words, in the freeze mode, the off-and-on control is decided according as the storage temperature is at the lower limit or at the upper limit and this control is outputted through means 26, 27 to the compressor 1 and the motor 11 of the blower 5 for the evaporator 4.
