Abstract: From the viewpoint of improving heating quality and saving energy, the paper proposes the use of Joint Heating Systems about Solar Collectors and Ground Source Heat Pump (JHSSCGSHP). The typical architecture in Shenyang is analyzed about dynamic simulation by the use of JHSSCGSHP. MATLAB is used to operate comparative analysis of simulation. It focuses on the impact of water temperature of inlet and outlet of heat pump systems in different series of separate heating of ground source heat pump and JHSSCGSHP. Thus the influence of the system operation efficiency based on different operation modes is compared.

Abstract: Adopting the k-ε standard model, the CFD simulation software to simulate the indoor kitchen and toilet different row of indoor air volume air distribution in natural ventilated circumstance, by comparison results show that different row of indoor air volume changes in the rate of secondary pollution rate, and then to provide the change rule of indoor air quality protection reference basis.

Abstract: in order to study and analysis on pressure distribution of pipeline system under the conditions of different power, to obtain the mutual influence degree between users. Through multi-storey residential pressure change exhaust system measured under the condition of three pressure changed board, the experimental results are compared and analyzed. The result of this paper obtains pressure of the mains and branch and branch speeds in different conditions. In six floors of 400 * 250 pressure changed type exhaust pipe system, no matter exhaust fan’s volume is high-end or low-end in any conditions can satisfy the exhaust requirements. Pipe internal pressure showed low - high – low.
