Презентация на тему Refrigeration And Air Conditioning

Conditioner

is used to cool products or a building environment.

Refrigeration & AC

(50 Tons of Refrigeration)
Centralized chilled water plants with chilled

water as a secondary coolant (50 – 250 TR)
Brine plants with brines as lower temperature, secondary coolant (>250 TR)

Refrigeration systems for industrial processes

Refrigeration & AC

energy
Vapour Absorption Refrigeration (VAR): uses thermal energy
Magnetic Refrigeration: remove

heat and maintain low temperature
Industrial Refrigeration:used in cold storage

Refrigeration systems

Refrigeration & AC

fluids tend to get colder when allowed to expand
If

pressure high enough
Compressed air hotter than source of cooling
Expanded gas cooler than desired cold temperature

The absorption system differs fundamentally from vapour compression

system only in the method of employed for compressing the refrigerant.
In the absorption system, the compressor is replaced by an absorber, generator and a pump.

a cooling technology based on the magneto caloric effect.

It

is used to attain temperature well below 1 Kelvin

systems for cold storage, process cooling, water chilling, individual

quick freezing .

Up to 500 TR capacity using halocarbon or ammonia.

Complete with compressors, condensers, all vessels and electrical equipment required

an assembly of different part of the system used

produce a specified condition of air within a require space or building.
The basic elements of air conditioning system:--
Fans : For circulation of air
Filters : For cleaning air
Heating Elements : Heating of air(It may be electric heater , steam , hot water.
Control System : It regulates automatically the amount of cooling or heating.
Grill : It adjust the direction of the conditioned air to the room.
Tray : It collects condensed water.
Refrigerating Plant : provide cooling . It consist of compressor/generator and absorber,eveporator,condensor,expansion device(capallary tube).

Window air conditioners are one of the most commonly

used and cheapest type of air conditioners

To install one of these units, you need the space to make a slot in the wall, and there should also be some open space behind the wall.

Refrigeration & AC

comprises of two parts: the outdoor unit and the

indoor unit

The outdoor unit, fitted outside the room, houses components like the compressor, condenser and expansion valve.

plants or the systems are used when large buildings,

hotels, theaters, airports, shopping malls etc. are to be air conditioned completely.

The window and split air conditioners are used for single rooms or small office spaces

are used for the cooling capacities in between these

two extremes.

The packaged air conditioners are available in the fixed rated capacities of 3,5, 7, 10 and 15 tons.

These units are used commonly in places like restaurants, telephone exchanges, homes, small halls, etc

Centralised Air Conditioning

say that, refrigerator consists with two compartments - one

for frozen items and the other for items requiring refrigeration but not freezing. It can throw all the heat from the loads inside the compartments and make it cooled and long lasting life. It suitable for application in food and medical industry.
We can also said that the objective of this experiment have been completely achieved as required and at the same time, all the parameters required to be solved have been calculated and solved accordingly. In addition, all of the experiments have eventually being done according to the procedures given systematically and appropriately.
