Difference Between Refrigeration and Air Conditioning Process. Refrigeration is a process where thermal energy is transferred from a place with lower temperature to a place with higher temperature using energy, against he natural flow of heat.. Air conditioning is a type of refrigeration which is used to cool large volumes inhabited by people.
Variations in pressure are important for refrigeration work.
The process where a gas or liquid change its temperature when it is forced through an expansion valve or capillary tube in an insulated system where no ambient heat transfer.
Training Session on Refrigeration & Air Conditioning.
The Once the refrigerant goes through the evaporator, it is sent again into the compressor… and the cycle continues repeatedly.Air conditioning is a type of refrigeration where thermal energy is taken away from the air in a large space such as a room or a vehicle.
Refrigeration and air-conditioning is the subject which deals with the techniques to control the environments of the living and non-living subjects and thus provide them comforts to enable them to perform better and have longer lives. Refrigerant changes state (boils) at a lower temperature when it is at a higher elevation which has less atmospheric pressure.
By then, it requires servicing to be done by a qualified

The condensed water can be then drained off.Air conditioners work in the same way as refrigerators. The working principle of air conditioning is Vapor Compression Cycle.

The “en::Image:Refrigeration.jpg with JPEG artifacts removed by a four-line Python program…” by Keenan Pepper (Originally from “Air Conditioners – Abstract” by zeevveez (Own work) [ The process where a gas or liquid change its temperature when it is forced through anRefrigeration basic principle named after two scientists, James Prescott Joule and William Thompson.This procedure is called a throttling process or Joule-Thomsonexpansion valve or capillary tube in an insulated system where no ambient heat transfer.The Refrigeration basic principle is that with the aid of a heat pump, the refrigerant is being compressed to the condenser and capillary tube thus increasing its temperature (50-60°C) and pressure (750 kPa) in the refrigerator being cooled down by the condensing unit to 32°C depending the existing ambient temperature.
Psychrometry Of Air Conditioning Systems. This can be understand easily from following image. When leakage occurs in the closed circuit then efficiency of the refrigerator will gradually diminished till it stops cooling. Air conditioners are fitted into rooms so that they cool the air inside them. Air conditioners also reduce humidity in rooms, because the water vapour in the room can condense around the colder parts of the air conditioner.
First of all understand basic geometry.
5 In 1974, Sherwood Rowland and Mario Molina predicted that chlorofluorocarbon refrigerant gases would reach the high stratosphere and there damage the protective ozone layer.
Upon entering the evaporator unit the gas expanded and vaporized due to sudden enlargement of the evaporator tube cross-section eventually dropping its pressure to almost atmospheric value (120 kPa) and temperature from 32°C to -24°C. Refrigeration basic principle named after two scientists, James Prescott Joule and William Thompson. Download Textbook of Refrigeration and Air Conditioning By R.S.
Air conditioners and refrigerators are devices used to keep a space at a colder temperature than its surroundings.

Heat absorption takes place from the evaporator and being pump-out by a heat pump to the condenser where being transformed from cool vapour to liquid state with higher temperature and pressure thus completing the heat transfer cycle.Theoretically, after the cycle the amount of refrigerant will remain contained in the system. For air conditioning calculations, the value of standard air is used for altitudes up to 2,000 ft. and for temperatures between 40°F and 100°F.
