This video clip could have been designed just for coastal North Carolina. Because I build hurricane resistant untra-tight houses, I am concerned with humidity year round and especially during the swing months in Spring and Fall when our HVAC systems seldom run at all. I have used the UltraAire dehumidifiers in several homes, but recently have tried the Aprilaire units for lower cost and much quieter operation(UltraAire can induce low frequency into the structure). In my personal home, we set the thermostats at 78 degrees and dehumidistat at 45 percent. Perfectly comfortable and my wife even uses a blanket sometimes in the evening while watching TV. I figure being able to run the AC at a higher temperature uses less electricity and helps make up for added usage from the dehumidifier. I have not been able to find an HVAC system that can achieve dehumidification during those swing months and not cool the house down too much. Unlike a dehumidifier, AC dumps the heat outside and thus has to drop indoor temperature to work. Great topic. Thanks.

Q about the TXV.

If the duct system contains a bypass damper which routes excess air back into the return will the TXV reduce/eliminate the amount of liquid refrigerant heading back into to the compressor?

I’m thinking that the reason my compressor failed years ago wasn’t due to the fact that the system didn’t have a TXV.
