What is centralized air conditioning system? How it works?

What is air conditioning system?

Air conditioning is the process of treating air to more favorable conditions such as changes the temperature, humidity, cleanliness, distribution. It can be classified as follows.

How to classify the air conditioning system?

v  According to the arrangement of equipment

ü  Unitary and central air conditioning system

v  According to the need

ü  Comfort and industrial air conditioning system

v  According to the season

ü  Winter and summer air conditioning system.

 

What is centralized air conditioning system? How it works?



The centralized air conditioning system consists of the following components

The main components available in centralized air conditioning system are

v  Filter

v  Heating coil

v  Cooling coil

v  Sprayers

v  Blower

v  Control panel

How does a centralized air conditioning system works?

v  Initially fresh air enters into the filter. It removes impurities and harmful bacterias present in circulating air.

v  Then the circulating air may be heated or cooled according to the season.

v  Circulating air is preheated by means of preheater during winter season.

v  Cooling coil is used to cool and dehumidify the circulating air during summer season.

v  Sprayer nozzle is also used to cool and dehumidify the air.

v  Blower circulates the cooled or heated air through the duct.

v  And finally circulated air sends into the rooms through grilled openings provided in the duct ways.

v  The central air conditioning systems is used for hospitals, theaters, and shopping malls, auditorium etc.,

What are the advantages of centralized air conditioning system?

v  Free of noise in rooms

v  Easy maintenance

v  Less running cost

v  Less capital cost

What are the disadvantages of centralized air conditioning system?

v  It requires duct

v  We cannot maintain different temperature for separate rooms if required.

v  It requires more space.

v  Any fault occurs all total system will collapse.

Working of four stroke petrol engine

   •        A four stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning the crank shaft. •        A four stroke engine delivers one power stroke for every two cycles of the piston. •        Following strokes are continuously taking place. ü   Suction stroke – Suction of air fuel mixture takes place. ü   Compression stroke – Adiabatic compression of air fuel mixture. ü   Power stroke – Combustion and adiabatic expansion taking place. ü   Exhaust stroke – Burnt gases are exhausted from the cylinder.       SUCTION STROKE :- •        During suction stroke, inlet valve is opened and exhaust valve is closed. •        Piston moves TDC to BDC •        When the piston moved TDC to BDC vacuum is created inside the cylinder. •        Due to the vacuum air fuel mixtures is drawn into the cylinder. •        Inlet valve is closed at the end of suction stroke. COMPRESSION STROKE :- •        In compression stroke

Does heat transfer takes place in vaccum space?

  Of course!  How earth receives heat energy from sun? Here is answer for these two questions. Heat can transfer in vacuum space. In this article you may know how heat is transferred in vacuum space.   How earth receives heat energy from sun? First we should understand the modes of heat transfer. There are three modes available to transfer heat. They are, Heat conduction, Heat convection and radiation. Let's see one by one.   Heat conduction In heat conduction mode of heat transfer heat is transferred by means of molecules present in the object. In this mode, energy will be transferred among the molecules. Example: I am holding a metal bar in my hand. I am going to heat that. What will happen. The bar gets heat from the source. Unfortunately, I can feel heat transfer in another side which is hold by means of hand. There is no objects present in the space. So heat cannot transfer by  conduction mode in space.   Heat convection In this mode of heat transfer heat is tr
