“…The uses of nanoparticle in refrigerant/lubricant mixture in improving coefficient performance/cooling capacity in refrigeration system were done by few researchers [4][5][6][7][8][9][10]. For example, Bi, et al [3] conducted experiment of mineral oil with TiO 2 nanoparticles mixtures as lubricant in domestic refrigerator.…”

Abstract. Nanolubricant been introduced in compressor might improve the performance of automotive air conditioning system. Prior testing of the nanolubricant enhancement performance, an automotive air conditioning (AAC) system test rig base on compact car has to be developed; therefore this paper presented the development process of AAC test rig. There are 15 thermocouples, 2 pressure gauges and power analyzer were assembled on the system in order to analyse its performance. The experiment was conducted with four different charged of refrigerant. The charging was based on initial weight charged. At each quantity of refrigerant charge, performance of the AAC system was evaluated by determining three important parameters which is cooling capacity, compressor work and coefficient of performance (COP). The maximum average COP is achieved at 900 RPM is 7.07. The average and maximum COP enhancement of 7.07 % and 13.34 % were achieved by applying SiO 2 nanolubricant inside the compressor.

“…Wang et al [38] utilised R134a, R407C, R410a and R425a with HFC based refrigerants mixed with NiFe 2 O 4 to investigate the reliability and performance of room air conditioners (RAC) with nanoparticles in the working fluid. NiFe 2 O 4 nanoparticles with 35 nm diameter were dispersed in B32 Naphtene based mineral oil to produce new mineralbased nanorefrigerant oil (MNRO).…”

“…Nanorefrigerant is the mixture of nano-powders and conventional refrigerant, and it is regarded as the new type of working fluid for improving the energy efficiency of refrigeration system [1][2][3][4][5][6][7][8]. As multi-walled carbon nanotubes (MWCNTs) have low cost and high thermal conductivity (up to 3000 W m -1 K -1 ) [9-12], they are suitable nano-powders for the preparation of nanorefrigerant.…”
