1. Features 1.1 1.1 Pr Prod oduc uctt F Fea eatu ture res s The DENSO sea container transport refrigerator uses an economizer cycle equipped with two compressors. In an economizer cycle, a portion of the high-pressure refrigerant from the compressor is expanded by the economizer expansi expansion on valve, and then supercooled by an economizer to improve refrigeration capacity capacity..
In the economizer cycle, compressor rotational speed is controlled by an inverter. Inverter control enables more accurate temperature regulation in relation to t o fluctuations in both ambient temperature and containerinternal temperatures, thereby reducing power consumption. In addition, using two compressors lowers the compressor compression ratio, thereby decreasing compressor motive power.
The sea container transport refrigerator is specially constructed for mounting to the container box. Since container boxes have no mating surface, insulation performance is improved.

Chilled operation is divided into chilled operation and frozen operation in accordance with the set temperature. When the set temperature is -10°C or higher, the system runs in chilled mode; when the set temperature is lower than -10°C, the system runs in frozen mode. During cooling operation the temperature inside the container is adjusted by changing the compressor rotational speed, and turning the heater ON and OFF.
(1 (1)) Chill Chilled ed Oper Operat atio ion n • When the set temperature is -10°C or higher higher,, the system runs in chilled mode. • In chilled chilled mode, the cooling cooling fan operates operates at high speed. speed. (During Eco mode, the cooling fan will operate at low speed.) • In chilled mode, the compressor rotational speed is regulated to adjust the air outlet temperature to the set temperature. When there is a danger of supercooling, the thermistor turns OFF (compressor stops), and the heater is energized to start heating operation. • The condenser condenser fan and each expansion expansion valve are optim optimally ally controlled. controlled. • When a humidity sensor sensor (optional) is installed, humidification operation (S06) is turned ON, and humidification operation is conducted in accordance with the set humidity (S07).

When there is a danger of supercooling, the thermistor turns OFF (compressor stops), and the cooling fan is switched to high-speed operation. • The condenser condenser fan and each expansion expansion valve are optim optimally ally controlled. controlled. • Humidificati Humidification on operation operation cannot be set when in frozen mode.
5.3 5.3 De Defr fros ostt O Ope pera rati tion on
Defrost operation starts when the defrost interval set for the defrost timer is reached.
During defrost operation the compressor, cooling fan, and condenser fan are stopped.
The heater is energized to heat the evaporator and melt any frost.
Defrost operation is completed when the defrost stop st op sensor reaches the set stop temperature, or when 90 minutes have elapsed since defrost operation began.
After defrost operation is completed, cold insulation operation (cooling operation with the cooling fan stopped) is initiated to start cooling operation.
