Why Don't I Need a DX Cooling Coil Plant-Side

I currently have a DX Cooling Coil providing cooling in my supply air, but I haven't got any sort of cooling plant in my model. If the element is truly just a cooling coil, wouldn't that mean that this is just the evaporator? How can cooling possibly be occurring?

What I was hoping was to have the condenser associated with this evaporator reject heat to a cooling tower. Is the element in OpenStudio a complete DX system (evaporator and condenser) with the assumption being that it is air-cooled?

Thanks!
