Hi,
I am modelling a baseline building according to System 8 in ASHRAE 90.1 Appendix G. I am using parallel PIU in all conditioned zones and all reheat coils capacities of parallel PIU are autosize. However, the reheat coil capacity of some zones has negative value when I get the simulation result. What is the meaning of negative capacity value for heating coil ? If somebody inform me I will be very glad.
