Abstract

Additional concern about warming of the global environment through the greenhouse effect has necessitated selection of compounds with shorter atmospheric lifetimes and higher energy efficiencies as substitute refligerants for Heating, Air Conditioning, and refrigerating equipment.Several substitute compounds of the hidrocarbon were identified by similarities in normal boiling points and corresponding saturated vapor pressure characteristics. Sample quantities were obtained from ITB (Two sample corresponds with CFCIZ named Hycool HCRI2 and Hycool HCR12+LFS). Performance comparisons among these refrigerants are performed utilizing Air Conditioning System test facility in Laboratory for Thermodynamics, Engines and Propulsion System (LIMP – BPP Teknologi). The results show that these alternatives refrigerants exhibit better performance than CFC I 2 at the predetermined operating conditions.

Abstract

In conjunction with the CFC phase out, IURC-ES ITB has been concentrating its research of HC refrigerant on ‘propane natural butane’ (PNB) refrigerant. The test results obtained in IURC-ES ITB during the development of the PNB refrigerant showed that PNB has better performance than PIB and CFC-12. The field tests of PNB also showed the similar results. Recently, to reconfirm the previous test results, the performance of PNB, PIB and CFC-I2 were compared in a series of performance tests in the LTMP Serpong. The tests also show that PNB consistently has better performance compared to PIB and CFC-12. This paper also reports the current development of PNB refrigerant in IURC-ES ITB.
