Abstract:

The work on improving the system performance in heating and cooling machines has become popular in recent years. This experimental study is aimed at ensuring energy efficiency by interfering with the compressor in the steam-compressed cooling circle. Instead of the polyol ester (POE) oil used as a working fluid in the compressor from the refrigeration system elements, the nano-fertilizer was used. In the preparation of the nanomaterials, a full synthetic and polyalkalene glycol (PAG) oil has been used as a base liquid. In the basic fluid, nanoparticles of zinc oxide (ZnO) and molybden tri-oxide (MoO3) are added in different mass fractions. Triton X-100 (TX-100) has been used as a surface active material to prevent accumulation in the nanoparticles. ZnO and MoO3 nanoparticles in the nanoparticles are incorporated into the basic fluid in 1,0% and 1,5% mass fractions, and the surface active material in TX-100 is incorporated into the basic fluid in 0.0% and 1,0% weight. The results of the tests were the performance of the cooling system. The best result; the basic liquid PAG oil was achieved by the use of ZnO nanoparticles in the 1.5 % mass fraction and the 0.5 % weight of the surface active material of the TX-100 nanoparticles as a compressor oil. As a result of the use of this prepared nanofertilizer as a compressor oil, the cooling coating rate (STK) was calculated at 4.65.
