Typically, cooling/heating energy implies the amount of fuel (electricity or gas) consumed to provide the thermal energy only. Equipment such as fans and pumps are generally not included in "cooling energy", because it's difficult to determine whether a fan/pump is being used for heating or cooling at any given time. For example, in a VAV reheat system, the air handler could be providing air to multiple zones with a single fan, some of which are calling for heating (reheating at the terminal unit), while others are calling for cooling (no reheat) or neutral supply air to satisfy ventilation requirements. Similarly, a pump that circulates condenser water to water-sourced heat pumps could be serving some units that are heating and others that are cooling.
If your systems are setup such that you can separate heating and cooling fans/pumps, you could label them as such in their end-use subcategory field, and they will be delineated in the End Uses By Subcategory output table.
I'm not sure what you mean by:
based on mtd file, the energy use for cooling should include supply fans, pumps, and cooling coil.
