Hey Guys,

I was wondering if I could get some advice as to the best methods of controlling and piping hot gas reheat coils. Here are a few questions/thoughts that I have.

I am tapping the discharge of my compressor and running to a stepper motor modulating valve. From there, the refrigerant cycles through my reheat coil and is dumped back into the discharge line through a check valve. Using this method, I have no real means to force X amount of refrigerant into the reheat coil even if the modulating valve is 100% open. Therefore, I thought about putting the modulating valve on the inlet of the condenser and a solenoid on the incoming side of the reheat coil. This way I can open the solenoid and throttle in as much refrigerant as required using the modulating valve. Do you guys see an easier/better way to do this? Do you guys have a good way of ensuring oil return back to the compressor and not getting stuck in the reheat coil while the circuit is shut down?
