GERMANY: Bock is expanding its transcritical CO2 compressor portfolio with a new series showcasing line get started lasting magnet (LSPM) motor know-how.
The LSPM compressors for use in refrigeration and warmth pump devices are explained to combine the strengths of robust squirrel-cage asynchronous motors and those people of synchronously operating long-lasting magnet motors.
Right after asynchronous beginning, the motor synchronises to the functioning frequency and then runs in synchronous manner without slippage. This simultaneous motor managing achieves a better refrigerant mass circulation with an optimised speed and as a result more cooling or heating ability, suggests Bock.
Because there are no energy losses in the rotor, the motor and all round compressor efficiency is increased by an average of about 6% as opposed to a typical asynchronous motor. Procedure can be adaptable, both directly from the mains or by using a frequency inverter.
The compressors start this thirty day period with 3 compressor dimensions giving a whole of 16 displacement phases from 4.8 to 39.5m3/h (50Hz/1,500 rpm). This covers a huge assortment of capacities, with just one compressor just about every ranging from 9 to 89kW in medium temperature cooling and 27 to 188kW in heating.
