This Stirling cycle involves an isothermal heat-addition process and isothermal heat-rejection process. . In reversed of heat engine‚ it has refrigeration system. Refrigeration system is the transfer system for heat from low temperature region to higher temperature region. The device that produces refrigeration is called refrigerator‚ heat pump and air-conditioning. The cycle they operate is called refrigeration cycle. The refrigerator and heat pump operate on the same cycle but different

TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further

at a low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus‚ it is possible to transfer heat from an area of low temperature (i.e.‚ water storage tank) to an area of high temperature (i.e.‚ environment). Regarding to the fig 3.1‚ beginning the cycle at the evaporator inlet (1)‚ the low-pressure liquid expands‚ absorbs heat‚ and evaporates‚ changing to a low-pressure gas at the evaporator outlet (2).The compressor (4) pumps this gas from the evaporator

Comparison microscope Stereoscopic microscope Micrometer caliper chronograph A comparison microscope is a device used to analyze side-by-side specimens. It consists of two microscopes connected by an optical bridge‚ which results in a split view window enabling two separate objects to be viewed simultaneously. This avoids the observer having to rely on memory when comHistory In the 1920s forensic ballistics was waiting at its inception. In

brick is able to store and absorb heat. With this property‚ heat lost is able to be prevented during night time and maintaining thermal comfort of interior during day time. In addition‚ bricks also consist of the characteristics of acoustic isolation. As bricks has greater density‚ thus it is able to provide higher acoustic insulation. Moreover‚ brick has high efficiency in revisiting and preventing the spread of fire due to its low thermal conductivity and high heat capacity. Low thermal conductivity

The term ‘urban heat island’ refers to the localized increase in temperature associated with an urban area. The UHI is an example of unintentional climate modification when urbanization changes the characteristics of the earth’s surface and atmosphere. It was observed that the UHI effect might result in minimum urban temperatures being 5-6° greater than the surrounding countryside. In the case of London‚ mean annual temperature was 11°C‚ while the surrounding countryside was 9.6°C and the suburbs
