Experimental and analytical investigation of refrigerant and lubricant migration
The off-cycle refrigerant mass migration has a direct influence on the on-cycle performance since compressor energy is necessary to redistribute the refrigerant mass. No studies, as of today, are available in the open literature which experimentally measured the lubricant migration within a …

Intermediate vapor bypass: A novel design for mobile heat pump at low ambient temperature
… was experimentally studied using low pressure refrigerants R134a and R1234yf. Severe heating capacity drop was noticed at extremely low ambient temperature, mainly due to low operating pressure in the outdoor evaporator. Decreasing suction density along with dropping evaporating temperature and …
