ShareA comparison of the oil return characteristics of R22-mineral oil and its HFC alternatives (R407C and R410A) with mineral oil and polyolester in a residential heat pump.
Author(s) : SUNDARESAN S. G., JUDGE J., CHU W., RADERMACHER R.
Summary
Refrigerant R22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems. R407C and R410A are two chlorine free HFC refrigerant candidates to replace R22. The paper describes the test methods and the results from controlled oil return experiments in a 3 ton residential split system. The HFC refrigerants are evaluated with mineral oil and polyoester lubricants and are compared to the R22-mineral oil baseline. The results support the decision to use polyolesters with HFC refrigerants in residential split heat pump systems.
