【 摘 要 】

In the recent couple of decades the demands for energy in India growing at a very high rate such a way that the conventional energy sources are not sufficient to meet the demand. At present most of the energy demand is met by fossil fuels, however, renewable energy sources such as solar energy, wind energy, biomass energy etc. have also been harnessed to some extent. The energy usage can be broadly classified to different purpose such as, building sector, industries, transport and household purpose. Among these one third of the total energy consumed in the world is spent for heating/cooling applications. It is to be noted that most of the heating/cooling demand are met by conventional system. This research work proposes a methodology for energy efficient space heating technique using solar coupled heat pump (SCHP) system under Indian climatic conditions by optimizing the COP of SCHP system and efficiency of solar collector using Taguchi technique. For the five influencing operating parameters of the system with three levels, an orthogonal array of L27 (35) has been selected using higher the better concept for 1 ton heating load capacity of the system during the winter season. Based on the 27 experimental trial runs it is found that the efficiency of solar collector and COP of the SCHP system varies from 38.8 % to 61.87 % and 1.9 to 3.01, respectively. The implementation of Taguchi method has resulted in 5.7% and 4.3% increase in solar collector efficiency and COP of SCHP system respectively.
