Page 34 Defrosting operation (1) Defrosting system A hot-gas defrost system is adopted in the units; i.e. the high temperature and high pressure refrigerant (hot gas) from the compressor is sent to the evaporator and drain pan for defrosting. Since the evaporator is heated directly by the hot gas (refrigerant), defrosting can be performed efficiently.
Page 35 (4) Defrosting termination conditions Defrosting time Defrosting termination conditions Within 45 minutes EOS≧20.0˚C Defrosting interval (frozen) EOS≧30.0˚C Short timer More than 45 minutes Defrosting interval (chilled) EOS≧30.0˚C ＆RS/DRS≧15.0˚C Out-range timer Manual defrosting 100 minutes Shutdown (100 minutes for the backup timer) Note 1 Defrosting operation is terminated when a protection device is activated.
Page 36 2.5.4 Dehumidification control operation (optional) Dehumidification control, like the defrosting operation, uses high temperature refrigerant (hot gas) from the compressor. It is executed by flowing the hot gas to the reheat coil mounted to the bottom of the evaporator. This control is optional, available for the unit equipped with a reheat coil only.
Page 37 2.5.5 Common control The following are controlled in different operation modes. (For the details, refer to the following pages.) Operation mode Control name Control content Frozen Chilled Defrost Dehumidification The compressor is operated on and off to A Compressor ON/OFF control adjust the inside temperature.
Page 38 Common control A : Compressor ON/OFF control When the control temperature reaches the set temperature or lower, the compressor is stopped. When the control temperature rises and becomes higher than the [set point temperature +1.0˚C], the compressor runs again.
Page 39 • By condenser fan control When the ambient temperature is low during the air-cooled operation, the condenser pressure (high pressure) will decrease. Accordingly, the low pressure will decrease. In order to prevent this situation, when the high pressure becomes set point or lower, the condenser fan stops to prevent the high pressure from excess dropping.
Page 40 I : Capacity control In the chilled mode operation, adjusting cooling capacity makes the supply air temperature stable at the set point temperature (SP). The capacity control is executed by adjusting the opening of suction modulating valve (SMV) between 3 to 100 %.
