Section SPS 322.45 - Air conditioner and heat pump efficiencies

(1) Heating and cooling equipment shall meet the minimum efficiency requirements in Table 322.45 when tested and rated in accordance with the applicable test procedure.

(2) The efficiency shall be verified through certification under an approved certification program or, if no certification program exists, the equipment efficiency ratings shall be supported by data furnished by the manufacturer.

(3) Where multiple rating conditions or performance requirements are provided, the equipment shall satisfy all efficiency requirements under this chapter.

(4) Where components, such as indoor or outdoor coils, from different manufacturers are used, calculations and supporting data shall be furnished by the designer that demonstrate that the combined efficiency of the specified components meets the requirements under this section.
