Horizontal Accumulator Selection

The purpose of this Technical Bulletin is to make the selection of horizontal accumulators for pump circulation and gravity fed systems quicker and easier by providing sizing curves. There is also, guidance given for the allowances which are needed to make adequate provision for liquid storage and surge volume. Guidance has been added on sizing vessels for HP float expansion valve, operation where we need a slightly larger vessel but we can reduce the refrigerant charge and total system cost. The standard range of vessels has been revised to use a shorter 1220mm diameter, vessel instead of a long 914mm diameter vessel because space restrictions regularly preclude the use of the longer vessel.
