WAC 51-11C-40333. Section C403.3.3 — Hot gas bypass

C403.3.3 Hot gas bypass limitation. Cooling systems shall not use hot gas bypass or other evaporator pressure control systems unless the system is designed with multiple steps of unloading or continuous capacity modulation. The capacity of the hot gas bypass shall be limited as indicated in Table C403.3.3, as limited by Section C403.5.1. Table C403.3.3 Maximum Hot Gas Bypass Capacity Rated Capacity Maximum Hot Gas Bypass Capacity (% of total capacity) ≤ 240,000 Btu/h 50 ˃ 240,000 Btu/h 25 Rated Capacity Maximum Hot Gas Bypass Capacity (% of total capacity) ≤ 240,000 Btu/h 50 ˃ 240,000 Btu/h 25 For SI: 1 British thermal unit per hour = 0.2931 W.
