5. ControlsUnit controls of the LGE air cooled screw chiller shall include following benefits and features.

General Information

1. Sequence of controlsWhen the product starts to run, the condenser fan and the water pump run simultaneously. In the same time, the magnetic valve 1 is turned on for the minimum low capacity operation. While the contactor position of condenser fans is checked, water flow is also checked a few seconds later after water pump run. In case of having no problem with water flow, startup delay will be activated. Approximately after one minute delay outlet temperature of chilled water is checked whether the water temperature is reached up enough to operate the compressor. When the PLC decides to operate the compressor, compressor starts with wye start and then delta start after a few seconds. During the starting process of compressor, while the compressor contactor is checking for problem, the solenoid valve for oil is opened in order to achieve proper oil circulation. After starting process, normal control starts. The normal control include capacity control, refrigerant mid pressure control for motor cooling, condenser fan control and alarm control. When the chiller is decided to turn off, compressor load of the compressor is changed to minimum load position by changing magnetic valve 1 and turning off magnetic valve 2 and magnetic valve 3. After the delay for shutdown, the compressor is stopped. When the compressor is stopped, the water pump will still run for a period in order to protect the compressor from frequent restart and withdraw latent heat from evaporator of chiller.

2. Adaptive chiller control and higher level protection.The latest chiller control technologies provide enhanced operations of the chiller. The chiller control system is based on recent PLC (Programmable Logic Controller) technology. Because the PLC is designed to be compatible with several electromagnetic interference and also compatible with severe ambient conditions, the unit has reliable controllability in any conditions. The adaptive chiller control is designed to operate the unit to withstand sever conditions and maintain its operation. Good examples are condenser fan controls by cycling according to the temperature of condenser refrigerant and the limitation of compressor capacity in the case of high chilled water temperature. Along with the adaptive control, the control also provides higher level protection through multiple protective devices. For example triple protective devices are used for the detection of abnormal oil circulation. The control system continues to monitor the hazardous conditions of the unit, and shutdown the unit to protect the unit safely when any condition meets safety limit.

3. Rich human machine interfaceThe HMI (Human Machine Interface) side of the PLC (Programmable Logic Controller) and HMI assembly is shown on the door side as shown in the below picture. The HMI is composed of wide full dot LCD with 4 line display and back light, 9 functional keys, and 15 indicating LEDs for rich user interface. Through the LCD interface, the operator can monitor the status of chiller operation and control in detail. And the control configurations also can be performed through the LCD interface. For the monitoring and the configuration, 7 menu items are prepared in the LCD display from main menu to parameter setting as shown in the below picture. In the below picture, amendable menu contents for the configuration are depicted with shaded color.
