Introduction: Alteration minerals are important indicators of thermochemical environments at the time of their formation – and thus indicators for the potential habitability of a site [1,2]. Therefore, the detection of alteration minerals, especially nontronite [3], on Mars was an important step to understand Mars’ hydrous history. This initial finding was followed by the detection of a wide va...

The fuel efficiency of cooling air at the inlet marine low speed diesel engine with water-fuel emulsion combustion by ejector chiller utilizing heat exhaust gas along route line Mariupol– Amsterdam–Mariupol was estimated. values available refrigeration capacity chiller, intake temperature drop and corresponding decrease in specific consumption main varying climatic conditions were evaluated. Th...

This paper describes the modelling and analysis of a 5 MW chilled water plant used for the cooling of a recently constructed data centre in the UK. The model was developed using the TRNSYS software with the aim of studying the impact of perturbations such as chiller failure on the water and air temperatures in the system. The model includes the chillers, hydraulic network (piping, valves and pu...

in this study,the effect of ozonated water(0.2, 0.5, and 1 ppm) with different exposure times (5,10, and 15 min) for control of staphylococcus aureus , escherichia coli and total counts in poultry carcass, on chiller water in slaughter house were investigated. for this purpose, control samples passed chiller water(without ozone) for (5,10, and 15 min) .other examples also treated (5, 10 , and 1...

Utilization of wasted heat instead of fuel combustion is effective to reduce primary energy consumption for mitigating global warming problem. Because wasted heat sources are not necessarily located close to areas of heat demand, one of the difficulties is that wasted heat has to be transferred from heat source side to heat demand side, which may require heat transportation over long distance. ...
