HPXML provides two difference HVAC system elements that can provide cooling:
CoolingSystem that only provides cooling and
HeatPump which can provide
heating and cooling.
HeatPump element in HPXML can represent either an air-source heat pump
or ground source heat pump in HEScore. Which is specified in HEScore is
determined by the
HeatPumpType element in HPXML according to the following
|HPXML Heat Pump Type||HEScore Cooling Type|
CoolingSystem element in HPXML is used to describe any system that
provides cooling that is not a heat pump. The
is used to determine what kind of cooling system to specify for HEScore. This
is done according to the following mapping.
|HPXML Cooling System Type||HEScore Cooling Type|
|central air conditioning||split_dx|
|room air conditioner||packaged_dx|
If an HPXML cooling system type maps to not translated the translation will fail.
Evaporative coolers are approximated in HEScore by a high efficiency central
Cooling efficiency can be described in HEScore by either the rated efficiency (SEER, EER), or if that is unavailable, the year installed/manufactured from which HEScore estimates the efficiency based on shipment weighted efficiencies by year. The translator follows this methodology and looks for the rated efficiency first and if it cannot be found sends the year installed.
HEScore expects efficiency to be described in different units depending on the cooling system type.
|Cooling Type||Efficiency Units|
The translator searches the
HeatPump/AnnualCoolEfficiency elements of the primary cooling system and
uses the first one that has the correct units.
Evaporative coolers are always assumed to be a
split_dx system with an
efficiency of SEER 28.
