LCCP evaluation for air-to-air heat pumps using next-generation refrigerants – Residential air conditioners.

Number: 1016

Author(s) : TAIRA S., HIHARA E.

Summary

 This report mainly describes the first step of the process through to the LCCP evaluation methods, together with the concept of the study utilizing field data and hypotheses. In particular, a representative model is selected as an example of general split-type air conditioners, and it is considered in two ways, one of which is only as evaluation for a system drop-in of candidate refrigerants replacement while the other is in terms of system optimization, both using the candidate refrigerants to be examined R290, R32, R454C (and R22, R410A). On the basis of such systems, this report explains a calculation method using the performance simulation that is adopted as a standard tool by the Japan Refrigeration and Air Conditioning Industry Association (hereinafter referred to as “JRAIA”). The report also presents an overview of a project to establish a new concept and hypothesis for LCCP evaluation in which field data related to air conditioners is adopted.
