Air Conditioners - Bought the Wrong Model
I am very late to this post. I apologize. Non inverter compressors run at two speeds only, one of which is the maximum speed, and the second one is off. It's either they run at full capacity, or they shut off. It's therefore no surprising that they achieve a lower temperature faster. They start from the very beginning running at full speed. Inverter units on the other hand modulate among a wide range of rpms. Usually, they start from a low rpm and they ramp up gradually as the pressure builds up in the refrigerant circuits. This prevents water hammer and thermal shocks. When they achieve the temperature set point, inverter units slow down and try to keep it as constant as possible. This greatly improves efficiency and comfort. But this is true especially for good quality inverters, having a wide modulation range, i.e. the capability of running at very low and very high rpm. There is plenty of cheap inverters in the market place which have a very narrow modulation field. Non-inverter units, a.k.a. fixed-speed units, on the other hand cannot adjust their output to the thermal load. Either they run at full speed or they shut off. Therefore, when the temperature set point is achieved, they start cycling between OFF and ON. This is inefficient and particularly annoying when the unit is greatly oversized compared to the thermal load of the room in which it is installed. It is worst during cool days or during the nights, less so on very warm days. Every time the compressor starts pushing at full rpm, the refrigerant circuit suffer a water hammer and thermal shocks. And it wastes a lot of energy too, since the start up is the phase during which energy is consumed without any significant benefit in terms of comfort. If we compare compressors to a vehicle engine the fix-speed compressor would in essence be an engine running always at full speed with no accelerator. The only way to limit the speed is to shut the engine off, and then fire it up again when the speed falls below a certain threshold. The inverter compressor on the other hand is equipped with an "accelerator" controlling its rpm and adjusting it according to the desired temperature. Now you can chose between inverter and fixed-speed. -

And of course Richard Nixon's awesome personality saw him both win and lose. -

Why Trump is the wrong man for job
Yeah. Impossible that other world leaders are morons. I mean, well, look at Starmer.... oodles of proof .... what a guy! -

Electric Vehicles in Thailand
We don't need a roof rack, and not a fan of them anyway. Minimal drag if using the streamlined roof 'boxes'.
