Abstract. This article regard the solar lithium-bromide absorption refrigerating air conditioning system as the research object, and it was conducting adequate research of the working principle of lithium bromide absorption refrigerating machine, also it was analyzing the requirements of control system about solar energy air conditioning. Then the solar energy air conditioning control system was designed based on PLC, this system was given priority to field bus control system, and the remote monitoring is complementary, which was combining the network remote monitoring technology. So that it realized the automatic control and intelligent control of new lithium bromide absorption refrigerating air conditioning system with solar energy, also, it ensured the control system can automatically detect and adjust when the external conditions was random changing, to make air conditioning work effectively and steadily, ultimately ,it has great research significance to research the air conditioning control system with solar energy.

In order to find a solution to the shortcomings and problems in construction engineering supervision in China, the achievements of previous studies are summarized, and the construction engineering Life-Cycle is divided into pre-investment period, while-construction period, project operation period, as offers a theoretical basis for the quality supervision of construction project. In addition, by analysing the problems in current quality management with the principles of science norms vs standardized management, system management vs Life-Cycle, tradition inheritance vs reform and innovation, the basic framework of CELCQS model is constructed, and the duty subject of life-cycle quality supervision, the management subject of government supervision and the control subject of public supervision are pointed out. Among them, the duty subject includes the units of development, reconnaissance, design, construction, and project supervision; the subject of government supervision consists of the competent construction administration department and the national development and reform department and the construction drawing censorship; and the subject of social supervision refers to the project quality detection agency and the engineering cost consultation agency.
