Speech Title: Research on the Electric Vehicle Heat Pump Air Conditioning System Based on R290 Refrigerant

Abstract: Based on the selection of refrigerant replacement for electric vehicle heat pump air-conditioning system, the ideal refrigerant replacement R290 is chosen as the working medium of the system. The feasibility and superiority of the electric vehicle heat pump air-conditioning system with water loop based on R290 refrigerant are verified by setting up a performance test platform. The experimental results show that the high temperature (55 °C) refrigeration capacity of the system is 5.77% higher than that of CO2 system, the COP of the system is 1.05 higher, and the isentropic efficiency of the system is more than 80% in the low temperature (- 20 °C) heating mode, the system has better and stable heating performance. This paper is beneficial to the further research and application of environment-friendly refrigerants, and further promote the development and research of heat pump air-conditioning system of efficiency electric vehicle.

Speech Title: Research on the Application of New Energy in the Design of Urban Public Facilities

Abstract: With the acceleration of the modern urban process, environmental pollution and energy shortage have become increasingly prominent problems. The development and utilization of new energy also serve as one of the effective ways to realize the sustainable design concept of urban public facilities. Via collecting and collating literature, this paper adopts a questionnaire and a field trip to understand the current status of the development of public facilities and the current composition and characteristics of new energy in Dalian. In this regard, the advantages and development points of new energy, as well as the regional and cultural characteristics of Dalian are analyzed. Then the abstract design is refined to create new works. To this end, a series of new energy public facilities with Dalian characteristics are designed using bionic design techniques, with a view to exploring new directions of urban public facilities design.

Speech Title: Research on Technology Evaluation of Green Low-carbon Building Based on Improved Order Relation-Extenics

Abstract: With the rapid development of social economy and construction industry, environmental pollution, ecological deterioration and other issues are becoming more and more serious. People pay more attention to the development of green low-carbon buildings. However, it is found that although the relevant evaluation standards are based on energy conservation, there is no clear quantification of building carbon emissions and social benefits, and it is impossible to comprehensively and scientifically evaluate the benefits of energy conservation and environmental protection brought by green and low-carbon building technologies. Based on this, combined with the latest green building evaluation standards, an evaluation index system of green low-carbon building technologies economic is put forward, and the indexes are assigned by the improved order relation method. According to the evaluation results, the green technology combination scheme is optimized to provide reference for the design of similar projects, so as to promote the development of green and low-carbon buildings.

Speech Title: Cobalt Phosphide Nanowire Arrays for Efficient Electrochemical Reduction of Nitrate to Ammonia

Abstract: The electrochemical reduction reaction of nitrate (NO3−RR) for ammonia (NH3) production under ambient conditions has received intensive attention due to the utilization of clean energy, the relief of extensive presence of nitrate in waste water, and low dissociation energy of the N−O bond. In this work, we report efficient NO3−RR to NH3 catalyzed by CoP nanowire arrays on the Ti mesh (CoP NWs/TM). It offers a large yield rate of 1.56 ± 0.42 mg cm−2 h−1 and a high Faradaic efficiency of 90.1 ± 2.7% for NH3 synthesis at a potential of −0.8 V versus reversible hydrogen electrode in 0.1 M Na2SO4 with 50 mM NaNO3 electrolyte under ambient conditions, and it also shows good durability and stability. Density functional theory investigations indicate that adding the first hydrogen of *NO3 to form *NO3H is identified as the potential determining step with a small free energy change.
