Abstract

A technique and results of computational, theoretical, experimental and numerical investigation of gas coolers of new design, intended for heating of the network water, when working in heat pumps using R744 as a working substance THCO2 are presented. It is demonstrated that when the recommended operational parameters are fulfilled, an essential increase in technical and economical indices of gas coolers and the whole THCO2 is ensured.
