Abstract

In this study, experiment to analyze heating performance characteristics of the inner condenser with air heat source has been done with various operating conditions, which are likely to match the air-sourced heat pump system test conditions under cold ambient conditions, such as variation of compressor speed. As the ambient temperature was decreased from 5°C to-10°C, the heat capacity of the inner condenser decreased by 54% due to the reduction of the refrigerant flow rate with the decrease of the refrigerant density of 45%. The heating capacity of the inner condenser increased by 40% due to higher refrigerant mass flow rate with the increase of the compressor speed from 2,000 RPM to 3,500 RPM. However, the COP of heat pump system decreased by 26% due to the additional compressor power.
