6.5.9 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 6.5.9 for VAV units and single-zone VAV units. Hot-gas bypass shall not be used on constant-volume units.
