Abstract: In order to protect environment, traditional fuel car will be replaced by new energy car. LNG is one of the new energy that be used widely now. On the other hand, vehicle refrigerator is being used diffusely. Traditional vehicle refrigerator needs automobile engine to provide extra electric energy to support its work. Indirectly, it will consume more fuel. According to the circumstance that car works, we study basic theory and experiment about recover the cold energy that LNG release during the gasification process to cool the refrigerator and provide theoretical direction to invent LNG zero energy vehicle refrigerator.#@#@#摘要: 出于保护环境的目的，传统的燃油汽车将会被新能源汽车所代替，液化天然气(LNG)是目前应用广泛的新能源之一；另一方面，车载冰箱的使用日益普遍，传统车载冰箱需要汽车发动机提供额外电能来支持其正常工作，间接增加汽车燃料消耗。论文依据LNG汽车正常的行驶状况，研究将LNG气化释放的冷能回收利用于车载冰箱供冷系统的基础理论和实验，为研制零能耗LNG车载冰箱提供理论指导。

摘要：
The chiller system in a building accounts for the main part of the building's total energy consumption, so it is critical to optimize the operation of chiller system for the purpose of saving energy. A chiller system generally consists of evaporation side and condensing side. The condensing side includes chillers, cooling water pumps and cooling towers, which form a subsystem of cooling water. It is a typical optimization problem to minimize the total energy consumption of cooling water subsystem. This paper discusses how to solve the optimization problem of the cooling water subsystem and proposes a simple optimal control rule for field operation based on the optimization results.

摘要：
In this paper, Simulink model is built to simulate the chilled water system of a real building. The optimal chilled water flow rate and chilled water supply temperature are found out by traversing the constrained parameter values under different working conditions. The simple optimal control rules are developed based on the optimal solutions. Optimal control rules can reduce the total energy consumption of the chillers, chilled water pumps, and air handling units by 17.55% compared with tradition control.

摘要：
Thermal insulation plays an important role in achieving building efficiency. Many engineering investigations were carried out to determine the optimum insulation thickness. In this paper, a coupled heat and moisture transfer model is presented to calculate the annual energy consumption. Then, the lifecycle total cost is analyzed by the P1-P2 economic model. Based on lifecycle total cost analysis, the optimum insulation thickness is determined. Three representative cities, viz. Changsha, Chengdu and Shaoguan, are chosen as the sample cities. The optimum insulation thickness, lifecycle saving and payback period are estimated. The results show that the optimum thickness of extruded polystyrene (XPS) is between 0.053 and 0.069m and the optimum thickness of expanded polystyrene (EPS) is between 0.081 and 0.105m. The maximum lifecycle saving varies from 16.60 to 28.50$/m2 and the payback period varies from 1.89 to 2.56 years. EPS is more economical than XPS as insulation because of its lower lifecycle total cost. (C) 2015 The Authors. Published by Elsevier Ltd.

摘要：
Based on long-term testing and recording of room temperate in a bedroom of residential buildings in the hot summer and cold winter zone, this assay focuses on comparative analysis of tested results and simulated results derived from the DeST software. It verifies the rationality and reliability of the DeST software, showing the feasibility that software DeST can be applied to analyze the energy consumption of residential building in hot summer and cold winter zone.

摘要：
As the building's outer wall consists of hollow blocks, the hollow hole will transfixion. According to the characteristic, this article proposes a technical method of indoor ventilation, which uses a hollow hole as channel and takes exhaust blower as the power which frequently use in the kitchen and bathroom, then carries on the simulation of ventilated effect for a typical room by the CFD method. With the analysis of the simulation result, the effect of ventilation is fine, and the method can solve the question effectively of city and countryside indoor air quality deterioration, and then achieves the goal of energy conservation.
