| Summary/Abstract |
As a renewable energy technology, the ground-source heat pump (GSHP) technologies have increasingly attracted world-wide attention due to their advantages of energy efficiency and environmental friendliness. This paper presents Chinese research and application on GSHP followed by descriptions of patents. The policies related to GSHP are also introduced and analyzed. With the support of Chinese government, several new heat transfer models and two new GSHP systems (named pumping and recharging well (PRW) and integrated soil cold storage and ground-source heat pump (ISCS&GSHP) system) have been developed by Chinese researchers. The applications of GSHP systems have been growing rapidly since the beginning of the 21st century with financial incentives and supportive government policies. However, there are still several challenges for the application of GSHP systems in large scale. This paper raises relevant suggestions for overcoming the existing and potential obstacles. In addition, the developing and applying prospects of GSHP systems in China are also discussed.

| Summary/Abstract |
In spite of over 10 years of heat metering promotion in China, there still lays a certain gap between actual application and expectation. In this paper, the author conducts a comprehensive carding of China's current situation of heat metering in the aspects of policy, price, application area, technical roadmap, product quality and so on. An application effect evaluation model is established based on the geometric mean weights method. Assignments and weighs of factors in the model are achieved via multi-agent wide range of questionnaires. Comparisons are made among model results, results published by Liu Xin and the results released from the Ministry of Housing and Urban–Rural Development of the People's Republic of China (MOHURD), which proves rationality and high accuracy of the model established in this paper. Evaluation results show that application of heat metering in 2012 requires improvement with the score pegged at 60.7. It is suggested that policy support from national government should be strengthened, the impact of policies released by provincial government be curbed and heat metering pricing be increasingly reasonable. Application conditions of different metering techniques routes need to be clarified and relevant standards need to be revised to improve the operation.
