    I think it varies depending on the manufacturer, but I think most just have higher speed taps on the motor windings that get energized when the thermostat calls for the 2nd stage.

    Normal subcooling varies depending on the design of a certain unit as well as the load and ambient temp. All things being equal, you generally have about the same subcooling regardless of refrigerant...

    The FLA rating doesn't mean much on motors of differing horsepower, since the tested full load of a 1/2 hp motor isn't going to be the same as the full load of the larger one. The smaller hp motor...

    Those tolerances are measurements for straight off the factory floor and there are so many things that can account for a slightly high amp draw. I know bosses don't make money on these cheap pm's...

    My guess is you have some non condensables that are circulating through the system and you don't have the correct charge so you're not seeing higher head pressure

    The latent heat is held by the water vapor. The refrigerant in the coil absorbs the latent heat in the water vapor as it condenses back to liquid

    You're removing latent heat from the air by dehumidifying it, but the refrigerant isn't absorbing latent heat if it's not changing state and that is where you get your btu capacity

    I'm having a little trouble following that, too. I think he's talking about an increased load(increased physical resistance), which would cause a higher amp draw to keep the rotor turning

    With a single cap tube(which I don't think it would be possible), you would have to use a bi-flow filter as their wouldn't be any check valves and you would only have one path for the liquid

    Inductive loads don't consume power like resistive loads. If you drop the voltage to a motor, it increases its amp draw. If you increase the voltage, amps decrease.
