Today, the reduction of fossil fuels and environmental pollution are two major challenges in the future of the world. The solution of these issues depends on focusing on two main strategies, including: development of alternative energy sources (especially renewable energy sources) and their applications, and improving the energy efficiency of equipment that consumes fossil fuels. According to the report of the International Energy Agency, energy consumption for the purpose of space cooling has experienced more than three times growth since 1990 until today, which raises the alarm of the global energy crisis more than ever before and the problems of providing cooling in the future. Therefore, in the current research, in order to create a suitable solution to overcome the above-mentioned challenges, the gas engine heat pump (GHP) system has been presented.
Keeping in mind issues such as the growing trend of electricity consumption in Iran, the recent shortage and outages of electricity in the summer, the lack of increase in the capacity of the electricity network due to the wear and tear of power plants and the phenomenon of global warming, it can be concluded that benefiting from The GHP system is a basic and efficient solution to overcome this crisis. In addition, the GHP system consumes 21.7% more gas than other systems during the peak cooling demand in summer, while this system reduces more than 70.1% of the peak gas consumption in winter.
give In this research, with the help of EES and Design Builder software and some other peripheral software, modeling, optimization and sensitivity analysis on the important parameters of the model have been done and technical, economic and environmental evaluations have been carried out. In addition, after verifying the design builder software with the help of the outputs from the EES software, a full comparison of the common air conditioning systems in home use with the GHP system is done.
The results of the research show that replacing and promoting the GHP system as a dual-purpose heating and cooling system can create positive effects on energy consumption and especially environmental indicators. In general, this system consumes 47.3% less primary energy compared to conventional air conditioning systems, but the results of the CO2 emission investigation report an average reduction of 62.8% in this case because Most of the common air conditioning systems in the market operate on the basis of electricity consumption, and the losses of energy conversion and transmission in the form of electricity include more CO2 emissions. Due to the lower and especially cheaper fuel consumption, the running costs of this system have been reduced by 45-85% compared to other systems, which, apart from the technical and environmental advantages, is the reason for the economic justification of the initial cost. The device turns.
