Abstract

A high demand on the energy and power has brought scholars more attention to investigate new ways to reduce the energy consumption. The aim of this research is reducing the power consumption required for air conditioning to cool the room by adding nanomaterials to the compressor oil at a mass concentration of 0.15%. Two models of chambers with dimensions (2 x 2 x 2) meters were fabricated to represent the test section and connected to a 1ton compressor, one operating with natural oil as a standard basis for comparison, while the other one with Nano-oil prepared in the laboratory. The mass concentrations of 0.15% of silver nanoparticles (Ag) were prepared, and the stability of the nanoparticles was tested by direct observation for different time periods. The results indicated that the performance of the air conditioner was better with the addition of nanoparticles to the compressor oil compared to the pure oil in the compressor. Reducing energy consumption in the cooling system by (19%). Also, it was found that there is an increase in the cooling speed of the nanotechnology system by (6%)as well as in the efficiency of the Nano-oil system compared to the regular system by (13%). This study showed that the thermophysical properties of the cooling oil increased by increasing the weight ratios of solid nanoparticles by (12%).

Highlights

Air conditioning is the process of treating the surrounding atmosphere by controlling the level of temperature, humidity, and air movement inside the place to be adapted, and to obtain an appropriate atmosphere in which the person is feeling comfortable and the appropriate temperature
Some researchers studied the performance of air conditioner and refrigerator for improving the energy consumption by (26%) with mixing ratio (0.1%) of TiO2 solid nanoparticles using in the hydrofluorocarbon (HFC134) system and Polyester oil (POE oil)

Summary

Introduction

Air conditioning is the process of treating the surrounding atmosphere by controlling the level of temperature, humidity, and air movement inside the place to be adapted, and to obtain an appropriate atmosphere in which the person is feeling comfortable and the appropriate temperature. Some researchers studied the performance of air conditioner and refrigerator for improving the energy consumption by (26%) with mixing ratio (0.1%) of TiO2 solid nanoparticles using in the hydrofluorocarbon (HFC134) system and Polyester oil (POE oil). The behavior dependence of the material on its diameter enables us to control the physical properties, and regarded to the conclusion of investigators that the behavior of nanoparticles is more technical implications that include varied and wide fields that include the tough and light particles production, shortening the delivery time of nanoparticles to the system of human circulatory, improving the absorption volume of magnetic tapes and computer preparation hot keys.
