Save Energy

More and more attentions have been paid on ice-storage low temperature air supply system because of its notable energy saving effects and comfort. The paper expatiate on that ice-storage low temperature air supply system brings a series of especial superiority to modern air-condition cause. The results show that low temperature air supply system can exert the potential advantage of ice-storage further. The combination of ice-storage and low temperature air supply system can obtain an “integrated approach”, which can save energy resources and improve human body comfort and indoor air quality.

The purpose of this study is to develop a portable energy-saving type air supply system. A variable volume tank is developed in order to drive a pneumatic actuator with a low discharge pressure in a tank. The developed tank composed of flexible materials can store pneumatic energy by converting it to elastic energy. In this paper, the composition of the system, the structure and characteristic of a variable volume tank and experiment of driving actuator with constant and variable volume tanks are discussed. As a result, the variable volume tank can drive the actuator at a lower supply pressure than with the constant volume tank.

Reducing Energy

In this paper, based on the new concept air power of pneumatic system’s energy consumption, we proposed series of practical program to optimize the air supply system. This program discussed a method of how to keep air pressure stable and how to make the amount of air compressors to match the real-time air consumption after using different air pressure for different devices, thus reducing energy loss of air supply system and energy consumption of air compressor group. The result of present work implied that this program achieved the desired effect of energy saving and provided a reference for energy-saving pneumatic system’s design.

Air Flows

A method of thermomechanical improvement of pulsating air flows in the intake system of a turbocharged piston engine is described. The main objective of this study is to develop a method for suppressing the rate of heat transfer to improve the reliability of a piston turbocharged engine. A brief review of the literature on improving the reliability of piston engines is given. Scientific and technical results were obtained on the basis of experimental studies on a full-scale model of a piston engine. The hot-wire anemometer method was used to obtain gas-dynamic and heatexchange characteristics of gas flows. Laboratory stands and instrumentation facilities are described in the article. The data on gas dynamics and heat exchange of stationary and pulsating air flows in gas-dynamic systems of various configurations as applied to the air supply system of a turbocharged piston engine are presented. A method of thermomechanical improvement of flows in the intake system of an engine based on a honeycomb is proposed in order to stabilize the pulsating flow and suppress the intensity of heat transfer. Data were obtained on the air flow rate and the local heat transfer coefficient both in the exhaust duct of the turbocharger compressor (i.e., without a piston engine) and in the intake system of a supercharged engine. A comparative analysis of the data has been carried out. It was found that the installation of a leveling grid in the exhaust channel of a turbocharger leads to an intensification of heat transfer by an average of 9%. It was found that the presence of a leveling grid in the intake system of a piston engine causes the suppression of heat transfer within 15% in comparison with the baseline values. It is shown that the use of a modernized intake system in a diesel engine increases its probability of failure-free operation by 0.8%. The data obtained can be extended to other types and designs of air supply systems for heat engines.
