Hot Water Coil Freezing

Anyone ever see a hot water coil freeze due to the cooling coil upstream of the hot water coil freezing?

No.

With out glycol (chilled water system) it's next to impossible to get 32 degree discharge air for any length of time (with any velocity). The conditions that would allow this to happen would manifest itself in a service call way before this type of event. In commercial systems you often see freeze t/stats that will shut the system down - manual reset as well (this is apparent with economizers).

It is best to get a temperature/pressure chart for different Freon types. You'll be able to see how different pressures/temperatures react. Post here if you have any further questions - will help if I can.
