Potential Reduction in Energy and Environmental Pollutants by Solar Assisted Ground Coupled Heat Pump Systems

Abstract

By the intensive development of industry, the intensity of the harmful gas emission has increased, which has resulted in global warming and climatic changes and fossil fuel cost, use of renewable energy has been welcomed.Solar assisted ground coupled heat pump systems are one of the important technologies that use renewable energy for residential and industrial cooling and heating system. In this system ground is used as a heat sink. In the winter the heat is taken from the ground and is transmitted to the building and in the summer it transmits the heat of the building to the ground without causing any pollution. Because of decrease in energy consumption and environmental pollution, it increasingly is favored all over the world. In this study the conventional cooling and heating systems and solar assisted ground heat coupled heat pump systems are compared from the aspects of CO2 and SO2 emission and the energy efficiency. We came to this conclusion that by reducing 30-60 percent of electricity consumption and reducing 10-30 percent environmental pollution gases, it is both economical and friendly environment. And finally ways to extend and increase the efficiency of this system is suggested.
