Carbon Economy

In mine air conditioning systems, the vapour compression refrigeration cycle seems to be currently the most widespread method of artificial cooling. In literature some other methods for cooling a mine are also presented, like using free-cooling in refrigeration systems. Mine workings in Jiu Valley are using the primary and secondary ventilation system for cooling the underground. Today the activities are focused mainly on mine closure as a part of transition to the low carbon economy, and this situation brings new challenges regarding the mine ventilation system, which was designed to meet the needs of a full-scale operation. As a result, locally ambient temperatures can rise, and spot cooling systems can be used, in order to cool the air. Such a system has been considered and calculations have been made to evaluate its thermal efficiency at different ambient temperatures.

Carbon Economy

This paper first defines the elements and meaning of rural low-carbon economy. On the basis of theoretical analysis, this paper then analyses the government role in the development of rural low-carbon economy, for example, government should organize and coordinate the development of rural low-carbon economy, should increase the investment of rural low-carbon economy, and should supervise rural low-carbon economy development as well. Last, the paper gives some suggestions for government to follow in the future work.
