MOE Engineering Research Center of Solar Power & Refrigeration

Brief Introduction

The Engineering Research Center of Solar Power & Refrigeration (SPR), approved by Chinese Ministry of Education (MOE), China,began its operation in May, 2001. SPR is devoted to developing new technologies on solar energy utilization, as well as low-grade thermal energy harvesting, more specifically, incubating new products and making them commercialization in corporation with well-known manufacturers. Its current activities involve solar thermal utilization, solar cooling, solar heat pump, and distributed energy systems (such as CCHP), etc, aiming at technology transfer, as well as fundamental research. The research group is very well known for its innovation activities in solar air conditioning systems, comprehensive use of solar energy in energy conservation of buildings, and so on. In the past several years, the group has not only published more than 200 papers at both international and key Chinese well-known journals, but also patented about 60 technologies in China. The research center is also eligible to undertake research and engineering projects, based on the research team led by Prof. R.Z.Wang. The foundation of SPR is a milestone for the research and utilization of solar energy in SJTU. SPR is now making great efforts with keen determination and a fresh outlook to build itself up to an Engineering Research Center at national level.
