 OS:ZoneMixing,
        \memo ZoneMixing is a simple air exchange from one zone or space to another. Note that this statement
        \memo only affects the energy balance of the "receiving" zone or space and will not produce
        \memo any effect on the "source" zone. Mixing statements can be complementary and include
        \memo multiple zones, but the balancing of flows between zones is left to the user's
        \memo discretion.
