From what I have read some units with a txv will not allow pressures to equalize during the off cycle. With these types of units, I suppose, (I really don't know for sure) is if they use start capacitors along with potential magnetic relays due to the high starting torque. But what really gets me to thinking is how does any TXV remain closed during the off cycle when as soon as the unit cycles off, the bulb for the metering device starts to naturally warm up. If the bulb warms up because there is no more cold vapor in the line during the off cycle the TXV opens regardless if the unit is in the off cycle or run cycle. So it would seem that all TXV units equalize pressures during the off cycle. But I know this can't be so. I know I missing something in my logic but what?
