Recommended Procedure for Rating and Testing of Variable Speed Air Source Unitary Air Conditioners and Heat Pumps

摘要

A procedure is presented for testing and rating variable speed, split residential air conditioners and heat pumps. The procedure is derived in part from existing procedures for single speed and two speed systems where these procedures could be applied, and introduces a new algorithm for representation of variable speed unit performance in the intermediate speed operation range. Analysis and background which led to the formulation of the procedure are included as well as calculation examples for the cooling and heating mode. The procedure has been prepared for the Department of Energy for consideration in the rule making process.
