Air conditioning actually has roots in second-century China, where an inventor named (a)   crafted a manually powered rotary fan.

The concept of air cooling also intrigued the great American inventor and statesman (a)   ,

Benjamin Franklin in (a)   conducted experiments with evaporation and alcohol to attain freezing temperatures. (date)

The first modern air conditioner was invented in (a)   by Willis Haviland Carrier (date)

was an American engineer and inventor, and is known as the man who invented modern air conditioning.

(a)  

allows customers to adjust home temperature remotely by computer or most web-enabled cell phones.

(a)  

allows the homeowner to adjust functions and settings on the air conditioner from off-site computers and web-enabled cell phones; `

(a)  

will even send text and e-mail alerts on when to replace the filter or arrange routine service inspections.

(a)  

The simultaneous control of the temperature, humidity, motion and purity of the air in a confined space

(a)  

is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed.

(a)  

AC provides a fix heating or cooling by a fixed power with the compressor running at a fixed speed. The compressor has to start and stop when required.

(a)  

are one of the most commonly used and cheapest type of air conditioners. To install one of these units, you need a space to make a slot in the wall, and there should also be some open space behind the wall.

(a)  

is one of the most widely used types of air conditioners. The major reasons behind the popularity of the split air conditioner are their silent operation and elegant looks.

Components of Split Air-conditioning System

(a)  

most important part of the any air conditioner. It compresses the refrigerant and increases its pressure before sending it to the condenser

(a)  

used in the outdoor unit of split air conditioners is the coiled copper tubing with one or more rows depending on the size of the air conditioning unit and the compressor.

(a)  

is an ordinary fan with three or four blades and is driven by a motor. The heat generated within the compressor has to be thrown out else the compressor will get too hot in the long run and its motor coils will burn leading to complete breakdown of the compressor and the whole air conditioner.

(a)  

usually a copper capillary tubing with several rounds of coils. In the split air conditioners of bigger capacities thermostatic expansion valve is used which is operated electronically automatically.

(a)  

components like the compressor, condenser, fan and expansion valve

(a)  

It comprises the evaporator or cooling coil, filter, cooling fan and louvers or fins.

(a)  

is a copper coil made of number turns of the copper tubing .

(a)  

very important part of the indoor unit. It removes all the dirt particles from the room air and helps supplying clean air to the room.

(a)  

while is sucks the room air it is passed over the cooling coil and the filter due to which the temperature of the air reduces and all the dirt from it is removed.

(a)  

air conditioning units provide a unique advantage in that they can be installed in locations where no wall or ceiling space is available so are often installed in cafeterias, convenience stores, large reception rooms, hotel foyers and comms rooms or server rooms.

(a)  

The cool air supplied by the blower is passed into the room. help changing the angle or direction in which the air needs to be supplied into the room as per the requirements.

(a)  

typically used in commercial spaces or food establishments.  It saves space and known for balance distribution of airflow.

(a)  

air, water, or both are used as working fluids to produce the required heating and/or cooling.

Centralizes Airconditioning System

(a)  

HVAC acronym

(a)  

Systems are milestones of building mechanical systems that provide thermal comfort

(a)  

system is designed to achieve the environmental requirements of the comfort of occupants and a process.

(a)  

The thermal energy transfer medium through the building delivery systems is air

(a)  

consists of an air handling unit, a heat source and cooling source, distribution ductwork, and appropriate delivery devices

(a)  

individual supply air ducts are provided for each zone in a building

(a)  

considers an adaptation of single zone system.

(a)  

a terminal-controlled modification of the multi-zone concept

(a)  

heated and cooled water is distributed from a central system to conditioned spaces

(a)  

introduced as a hybrid system to combine both advantages of all-air and all-water systems.

(a)  

are externally similar to fan-coil units but internally different. induces the airflow in a room through a cabinet

(a)  

Used to provide considerable energy savings for large buildings under extreme cold weather.

(a)  

A single zone will require a complete, single package of heating system which contains heat source and distribution system

(a)  

include active systems as air-conditioning systems that provide cooling

(a)  

forced systems by using devices such as window fan to allow air movement between outdoo

(a)  

contain two central devices: the condenser, located outdoor, and the evaporator, located indoors.

(a)  

system may serve one or more thermal zones

(a)  

System that serve a single zone which needs equipment located inside the zone itself, such as small houses or residential.
