Literature Review 2.1 History of the air-conditioner Air-conditioner was invented based on invention of refrigerator. The history was told that the Chinese were the first to store natural ice and snow to cool wine and other delicacies. Evidence has been found that ice cellars were used as early as 1000 B.C. in China. Early Greeks and Romans also used underground pits to store ice. Ancient people of Egypt and India cooled liquids in porous earthen jars. Ice was produced due to vaporization

Air Conditioning Systems An air conditioning‚ or HVAC&R‚ system is composed of components and equipment arranged in sequence to condition the air‚ to transport it to the conditioned space‚ and to control the indoor environmental parameters of a specific space within required limits. Most air conditioning systems perform the following functions: 1. Provide the cooling and heating energy required 2. Condition the supply air‚ that is‚ heat or cool‚ humidify or dehumidify‚ clean and purify‚ and

Lab 9 Home Meteorology Lab Introduction to Physics I Laboratory 1. Introduction Lab nine‚ the home meteorology lab‚ is a hands-on experiment that will allow me to use real world items to experience and observe condensation in my own home. There will be a graph that will include the information regarding the experiment such as 1) the room temperature of standing water 2) the dew point temperature of the standing water‚ and 3) the result of relative humidity. Through this

Climates and Oceans- 1. With coastal climates‚ the locations are on the windward side‚ meaning the weather patterns move from the ocean to land‚ giving them mild summers and cool winters. This means that there isn’t a very large temperature range for coastal climates. Inland climates are more of the land heating and cooling‚ because they heat to high temperatures in the day and then cool a great amount at night. Also‚ the weather patterns are moving from land to water‚ creating warmer summers and

Cargo Handling Safety 1. Why cargo gear should be inspected visually before the start of cargo operation? All cargo handling gears should be inspected before the cargo operation is commenced to ensure that all gears are in good working condition in order to prevent any accident and/or damage to cargo‚ ship‚ and/or injuries and loss of human lives. 2. Why SWL of equipment should never be exceeded? Safe Working Load (SWL) is the allowable load of block‚ wires‚ ropes‚ derrick booms‚ crane jibs‚ hooks
