Development of the circulating composition sensing circuit for a multiple split type air conditioner with R407C.

Summary

A composition sensing circuit which detects the circulating composition of R407C in the refrigeration cycle has been developed. This circuit consists of a heat exchanger, a capillary tube, two temperature detectors and one pressure detector. In the composition sensing circuit, the circulating composition is indirectly detected from the temperature and pressure information using vapour-liquid equilibria for R32-R125-R134a mixtures.
