As long as the unit delivers required air quantity at the appropriate filtration level it is immaterial whether the cooling comes from a chiller or aDx unit. The other thing you need to be mindful is that a refrigerant leak should not deplete oxygen level in the patient room so the main condensing unit sizing needs to take this into consideration
