I want to model a Direct Evaporative Cooler for a multi-zone residential building. I have found the example "1ZoneEvapCooler" which uses an "AirLoopHVAC" object. My question is what is the difference between the AirLoopHVAC and the "ZoneHVAC:EvaporativeCoolerUnit" object when simulation an evaporative cooling system.

If you want to use evaporative cooling in a single airloop serving more than one zone, or combine it with other equipment, then use one of the evap coolers that can go in an airloop. Each one has slightly different capabilities:


If you want a simple single-zone evap cooler, then use ZoneHVAC:EvaporativeCoolerUnit.

In the example files folder, file ExampleFiles-ObjectsLink.html lists every object type with a few example files that use it.
