Summary

Theoretical cycle analysis is an indispensable part of the refrigeration system and heat pump (HP) design. However, due to the simplicity of the calculations and numerous assumptions, there is a deviation from the actual behavior of the system. In this paper, a single-stage, reversible CO2 system, which can operate in both air-conditioning and heating mode, with and without an internal heat exchanger (IHX), was presented. In the heating mode, the deviation of the theoretical cycle from the actual cycle of the heat pump was analyzed, under various operating conditions. Actual cycles were formed based on the experimental investigation of this system. The changes of various parameters and deviations that are made due to a simpler calculation are presented.
