Infer plant loop temperature logic

[pflaumingo]

The loop temperature needs to be inferred based on the type of equipment that is on the loop. It is important to note that no objects that are available in Revit (i.e. a chilled water loop) should be created behind the scenes to improve the engineering quality. For example, if high and low temp chilled water components are on the same loop then an additional loop for the higher temp, perhaps served by an HX from the low temp loop, should not be created. Currently the proposed logic for the loops are:

• Hot water loops: Fixed 140F supply with 30F delta T
• Chilled water loop: If a low temp component (i.e. FPFC, air handler cooling coil, etc.) is present then 44F is supplied, otherwise 57F is supplied.
• Condenser loop: 70F fixed supply temp. If a dx heating coil is present then a boiler should be added to keep temp above 50F (not implemented yet)

Steps to complete issue are:

1. Discuss in this thread the final logic
2. Create an implementation design in the code
3. Write tests
4. Write code
