none worth speaking of. We've been stringing 50-100m cat5s round car bodyshops with 3-phase starters and inverter welders and never seen a problem. Now wifi OTOH...
I think it'll depend more on the gas than the compressor, tbh. You need to make enough pressure to liquefy the gas so it can then be expanded again. The compressor will only be able to do this above a certain speed, and then the expansion valve can only throttle the flow a certain amount too.
Absolutely. Same with COP too as the required temp combos may result in the inverter throttling-back as it strives to achieve the most efficient pressure ratios. Speaking of, did you ever look at that TUV document I sent you for the CoolEnergy unit?
^yep DC injection would do it.
I've just re-read the TUV report for the CE-iVT9, and it quotes standby at 9W and the crankcase heater at an additional 33W
Hopefully we will find out with a bit more investigation.
How low could a compressor motor go in the power factor. 0.5 is appealing.
but it's not being "motored", it's a resistive heater at that point...
I used some spare MVHR duct to run cables 25m out to my shed recently. We pulled a 6mm SWA, a multicore Hituff, a cat5, and a drawcord, all through in one go with no hassles whatsoever, and that included one slow bend and 2x 90deg soil bends too...
