I am modeling a solar cooling system in EnergyPlus and while running the simulation I've got this severe error: ** Severe ** PsyRhoAirFnPbTdbW: RhoAir (Density of Air) is calculated <= 0 [-9.04677]. ** ~~~ ** pb =[101100.00], tdb=[-312.09], w=[0.0000000]. ** ~~~ ** Routine=CorrectZoneHumRat, During Warmup, Environment=DSDAYTANGIER COOLING 0.4%, at Simulation time=08/21 00:12 - 00:13 ** Fatal ** Program terminates due to preceding condition.  I also got a warning that the calculated cooling load is zero, and also the water heater's Recovery Efficiency and Energy Factor could not be calculated during the test for standard ratings. I tried to hard size the cooling coil but the results are the same. If anyone could help I'll be grateful.
