The hot gas or drained liquid bypasses the new nozzle position. In addition, the
liquid / vapor mixture flowing from the thermostatic expansion valve passes through
the extended nozzle. This tube eliminates any interference by hot gas entering
through the auxiliary connection with the flow from the thermostatic expansion
valve.
When an ASC is used to introduce hot gas to the evaporator inlet for capacity
control the distributor feed tubes generally should be one size lager than that
recommended for straight cooling duty - See table of Distributor Tube Circuit
Capacity - Tons, page 13, Bulletin 20-10 dated June, 1975. However, if the hot gas
bypass flow does not exceed the equivalent of 75% of the design cooling load then
tubes sized for straight cooling duty will be adequate.
