This study investigates cold thermal energy storage (CTES) using a helical coil heat exchanger modified with bubble injection. One of the effective methods for increasing transfer rate in exchangers is A immersed inside cylindrical water tank, where evaporator vapor compression refrigeration cycle (VCRC) and provides designed cooling. Experimental studies were carried out to examine impact inje...

Recently, a heat source system utilizing a heat storage tank for energy savings in buildings was designed. A heat storage tank is an effective system for solving the qualitative and quantitative differences in the required building energy. On the other hand, the existing design process of a heat storage system is difficult to determine if the air-conditioning time is unclear, and the design in ...

The paper covers the principles and design aspects of cylindrical bins for the storage and reclaimation of bagasse. The system described (fig. 1) was originally designed and drawn up by the author in 1963 for the Mossman sugar mill. The design was not adopted, favour being given to the more conventional rectangular system with travelling suspended reclaimer. The first circular system, with a ca...

Bisphenol A (BPA) as a chemical hazard may enter the milk chain during primary production at farm and, successively, processing dairy company. To identify potential pathways that play role in occurrence of BPA, monitoring model for risk assessment based on identification hazards each stage was investigated. Milk samples were analyzed using liquid chromatography with fluorescence detection. Quan...

The utilisation of hydrogen in ships has important potential terms achieving the decarbonisation waterway transport, which produces approximately 3% world’s total emissions. However, drives maritime and inland shipping is conditioned by efficient safe storage as an energy carrier on ship decks. Regardless type, constructional design purpose aforesaid vessels, preferred method for currently high...

Fire and explosion accidents often occur in storage tanks leading to great economic loss and serious casualties during the working, operation and maintenance. This paper established a reduced-scale storage tank experimental system, and then the explosion characteristics of gasoline-air mixture in storage tank were studied. The experimental results show that several parameters (such as concentra...
