?xml>Frequency-controlled Bock power racks operate using two semi-hermetic HI series compressors, where one frequency-controlled compressor takes the role of the master compressor and the second compressor is activated unregulated by the frequency converter. These units have been specially developed for use in refrigeration systems with variable refrigeration demand. The use of a Power Electronics Yaskawa frequency converter allows compressors to run continuously while optimally adjusting cooling performance to the current conditions.
The partial load behaviour has been further optimised compared to the E-FU-1BO devices by dividing power across two compressors. These devices are therefore an energy-efficient and space-saving alternative to power racks with multiple compressors. The Bock power racks are available in 6 different performance classes. Refrigerants R134a/R404A/R507/R513A/R450A/R448A/R449A can be used. The maximum frequency may be limited for air conditioning applications. Cooling power is regulated depending on the intake pressure.
A Power Electronics Yaskawa frequency converter is used in combination with a pressure transmitter to control the power rack. This is mounted and thermally decoupled on the intake side and records the actual intake pressure value. The frequency inverter regulates the cooling power of the rack so that the target value is achieved as closely as possible. The frequency converter is included with the control box. Configuration is input via a keyboard. The frequency convertor comes pre-configured. Only a small number of parameters must be changed to make changes to the refrigerant used and the place of use. The control box is mounted to the frame and wired. All components are mounted to a tough riveted steel profile frame. All parts of the frame are powder-coated. The power rack stands on the supplied rubber-bonded metal base. Refrigeration lines are conveniently grouped together at the rear and can be shut off. Power racks are fitted with an oil separator as standard in order to ensure reliable operation, even during a temporary minimal cooling load on the system.
