llf12 A simple high side float can separate liquid from the reheat flow and bypass the secondary condenser. However, this is best suited for a parallel style system, and whereas this can be extremely simple solution where you only need a small portion of the total heat of rejection,(10 to 20%)...

There are several issues to contend with here. Oil return is not usually a concern, as the oil is miscible with the liquid refrigerant and if the liquid refrigerant flows correctly so will the oil. The issues are with refrigerant managment. You will need a receiver, and some method of flooding...

I have listened and just have to put my two cents in. I work for an air conditioning manufacturer. We spend a lot of time and money trying to make our systems more efficient. Examination of a standard Pressure enthaply diagram or a temperature Entropy diagram and a component balance graph, will...

WOW the eveporator is only 4x6 inches? I cant envision a 1/4 ton of circuiting in that area without a high deltaT. If the components are not all balanced for the load at a specific evap temperature, perhaps the hand expansion valve would be the most forgiving solution. Some flowmeters in that...

Much more detail would be required to give a definative answer. There are several options to use as a metering device in your VCRU. 1) hand expansion valve (what you are suggesting) 2) Capillary tube 3) automatic expansion valve 4) Thermostatic expansion valve 5) Electric or electronic...
