| 摘要 |
The present invention relates to a thermodynamic cycle process system comprising at least two heat exchangers, an EC compressor (1), and a combination of electronic components such as EC fans (2), electronic regulator valves (3) and/or EC pumps (4). A central supply electronics unit (5a, 5b) can be connected to an AC voltage source (15a, 15b), wherein the electronic components (1, 2, 3, 4) have an integrated power electronics device (6a, 6b, 6c, 6d) which produces the PWM operating voltage required for the electronic components (1, 2, 3, 4). The central supply electronics unit (5a, 5b) is connected to the individual integrated power electronics devices (6a, 6b, 6c, 6d) for the electronic components (1, 2, 3, 4), and produces the supply voltages required for the respective power electronics devices (6a, 6b, 6c, 6d). |
