Techshore Inspection Services -Kochi-Kerala | Vapour Compression Notes Introduction Vapor compression refrigeration cycle is the basic working cycle of a refrigeration system. The vapor-compression refrigeration system uses a circulating medium called refrigerant is the medium which absorbs heat from the space to be cooled and subsequently rejects that heat from the room to outside. Figure describes a typical, single-stage vapor-compression refrigeration system. It have primarily four components: compressor, condenser, thermal expansion valve (also called a throttle valve), and evaporator. Circulating refrigerant enters the compressor in the saturated vapor state and is compressed to a higher pressure, higher temperature vapor. The high temperature, high pressure vapor is then in the superheated vapor and it is at a temperature and pressure at which it can be condensed with cooling water or cooling air flowing across the condenser coil…

Techshore : Split Air Conditioning System

Mechanical Engineering, Mechanical Engineering
Air Conditioning Introduction Air conditioning is the process of altering the properties if air (primarily temperature, pressure and humidity) to more favorable condition.The control of these above conditions should be desirable to maintain the health and comfort of the residents, or to meet the requirements of industrial process irrespective of the external climatic conditions. The split air conditioner The split air conditioner comprises of two parts: the outdoor unit and indoor unit. The outdoor unit, fitted outside the room, houses components like the compressor, condenser and expansion valve. The indoor unit comprises the cooling coil or evaporator and the cooling fan. For this unit no need to make any slot in the wall of the room. Further, the present day split units have artistic looks and add to the prettiness…

Techshore : Oil And Gas Storage

Techshore : Oil And Gas Storage

Mechanical Engineering, Mechanical Engineering
INTRODUCTION On most of the production units, oil and gas are directly piped to a refinery or tank terminal. It is difficult to store gas locally, but in certain cases underground mines, caverns or salt deposits can be used to store gas. On production units without a pipeline, oil is stored in onboard storage tanks to be transported by shuttle tanker. The oil is stored in storage cells above the shafts on concrete platforms, and in tanks on floating units. On some floaters, a separate storage tanker is used. To balance the buoyancy in both cases when the oil volume varies, the usage of ballast handling is very important. For onshore, fixed roof tanks are used for crude, floating roof for condensate. Special tank gauging systems such as pressure, level…

Hydraulic Wind Power Transfer Systems

Hydraulic Wind Power Transfer Systems

Electronics & Instrumentation Engineering, Mechanical Engineering, Uncategorized
 INTRODUCTION  There has been a significant improve in wind energy generation systems throughout recent years. However, high capital investments and low capacity factors are still the remaining issues . Holding the stresses applied by the weight of the structure requires reliable foundations which considerably increases the implementation cost. The average lifetime of the conventional wind turbines is almost 20 years. However, their gearboxes should be replaced after the operation period of 5 to 7 years, and this replacement can be as costly as 10 percent of the entire turbine . In the conventional wind farms, each wind turbine is comprised of a gear box, power electronics, and a generator all implemented in nacelle. Recently, new generation of wind turbines is introduced in which a hydraulic system is designed and utilized…

Power Generation Using Speed Breaker

Power Generation Using Speed Breaker

Electrical & Electronics Engineering, Mechanical Engineering, Uncategorized
                 INTRODUCTION In the present day scenario power has become the major need for human life. Energy is an important input in all the sectors of any countries economy. The day-to-day increasing population and decreasing conventional sources for power generation, provides a need to think on non-conventional energy resources. Here in this paper we are looking forward to conserve the kinetic energy that gone wasted, while vehicles move. The number of vehicles passing over speed breaker on road is increasing day by day. Beneath speed breaker, setting up an electromechanical unit known to be power hump, could help us conserving this energy and use it for power generation. The electrical output can be improved by arranging these power humps in series. This generated…

Study Of Underwater Wet Welding Stability Using X-Ray Transmission Method

Mechanical Engineering
CHAPTER 1 INTRODUCTION The wet welding process, which is a widely used underwater welding technology, is conducted directly in water without the use of any additional engineering vessels, complex chambers or shielding gases. The simplicity of the wet welding process allows even the most geometrically complex structures to be welded. According to Richardson et al. (2002), underwater wet flux-cored wire welding process, which is suitable for automatic welding processes conducted in deep water, has considerably higher production efficiency than that of underwater manual metal arc welding. The special operating environment is hypothesized to have a significant effect on the arc behavior, metal transfer, welding metallurgy and welding stability. Therefore, it is necessary to develop an effective method and statistical model for quantitatively estimating arc stability during the underwater wet flux-cored…
