Re: [TRNSYS-users] Type 52



When no air (or very little) passes through the coil (type 52b), the outlet air temp becomes that of the coil water. I have a problem that the type is internally calling a routine for the wet-bulb calculation which is outside of range (Temp more than 70 degC). This error is TERMINATING my simulation although I only get it once. I also get a saturation warning everytime condensation occurs on the coil when I use it as a cooling coil. I have been advised to recompile this type with some adjustments, but I have no resources to do so. Please advise.
