[TRNSYS-users] HRV Type 667

[Charron, Rémi]

Hello, 

I was having problems with TRNSYS freezing on occasion during the simulation.  I figured out that this only happened when I was using HRV Type 667 with exterior temperatures below approximately -32ºC. I am using an HRV Type 667 linked with a Type 19 zone model.  It does not matter if the HRV had its flow going to the zone or not.  The only thing that made the program stop crashing is by placing the flow through the HRV at 0. Have other people experienced this problem.  If you want to test it, I suggest using Iqaluit weather data (\Trnsys16\Weather\Meteonorm\North-America\CA-NU-Iqaluit-Frobisher-Bay-719090.tm2).      

Another comment on Type 667, it is very slow.  When the HRV is on it more than doubles the time it takes to run the simulation.
