    3 pipe Thermobank

    Got some 0* walk in freezers using single compressors and gas defrost and Thermobanks.

    The gas defrost line enters the evaporator coils in between the TEV outlet and the distributor inlet by using a 1 1/8" copper Tee fitting.

    Question is, Doesn't the gas defrost line need to enter into the coil through a side ported distributor?

    Defrost works fine the way it is.

    But in my supermarket experiences with reverse gas defrost, side ported distributors are necessary because you won't get the required flow rates through the distributor nozzle.

    Never seen any other thermobank systems to compare. But it just seems like we shouldn't be pushing defrost gas through the nozzle. It will slow flow rates and slow down defrost.

    After some digging, it's supposed to be a side ported distributor.

    Should be a side outlet tee, or an auxiliary side connector. If there is just a standard tee, if forces the hot gas to flow through the distributor nozzle, which will result in a high pressure drop.

    The side outlet distributor, or auxiliary side connector will allow the hot gas to enter downstream of the nozzle.
