This session focuses on the testing techniques improvements and projections for heat pumps and air conditioners. Existing index IEER and SEER fail to properly capture the dynamic effects and potential energy savings of advanced unit controls. This seminar discusses different load based testing methods in order to provide a figure of merit for air conditioners and heat pumps. Test procedures, lab requirement as well as system performance are discussed. This seminar also covers the test procedure changes in DOE Appendix M1. Overall, this seminar provides the current research development and standard change on load-based testing method of air conditioners.
