Chiller with variable-speed compressor operates effectively between 10 and 100 percent of its rated capacity. The design applies variable-speed green compressor technology from the HVAC industry to produce energy savings over traditional hot gas bypass regulation. The chiller control allows for cloud-based remote management with full-featured operational data sets. These include suction and discharge temperatures and pressures, water temperatures and pressures, tank level and other sensor inputs. The data sets are logged, and alarms can be transmitted in real time to allow complete viewing and operational control via PLC, PC, tablet or phone. In addition, the chiller offers other standard communication protocols, including Modbus and Ethernet. The controls can regulate temperature to within 0.5°F. Other features include electronic expansion valve technology with high accuracy metering to deliver precise refrigerant flow and variable-speed condenser fans.
