[Equest-users] Request for Clarification on PTAC

Anura,

Yes, the PTAC is a PTHP when you select heat source as "Heat Pump". These two units cool the same way,  but differ in how heating is done.

HTH,

Subject: [Equest-users] Request for Clarification on PTAC

Dear All,

As per the Appendix G requirement, for my project, the Basecase HVAC system has to be system type- 2 which is Package Terminal Heat Pump, DX Cooling, Electric Heating. (from Appendix G)

When this is selected from the appropriate menu and the simulations are done, the output file indicates the system type as PTAC. This usually stands for Packaged Terminal AC. In principle it can also mean Packaged terminal Heat Pump as AC is also a Heat Pump.

Can PTAC be taken as to mean Packeged Terminal Heat Pump as well as given in the output file or is eQUEST performing something starnge ??

Thanks in advance for any clarification

Anura
