The document discusses different types of air conditioners and heaters. It explains the basic principles of air conditioning as using vapor compression to minimize air temperature through a condenser, compressor, expansion valve, and evaporator. It then describes four main types of air conditioners: window units which are inexpensive but can only be installed in windows; portable units which are movable but require setup; wall split or multi-head split systems which have an indoor and outdoor unit connected by tubing; and ducted systems which deliver air through ductwork to rooms.

HEATERS
PRANJAL PATIL

2. WHAT IS AC?
The process of removing heat and controlling the humidity
of air in an enclosed space to achieve a more comfortable
interior environment by use of powered “air conditioners”
or a variety of other methods including passive cooling
and ventilative cooling.

3. What are the principles of air conditioning?
The basic AC principle is a vapor compression cycle to minimize the air temperature
with the help of a condenser, compressor, expansion valve, and evaporator. The
complete cooling process is a heat transfer taking place among the room air and
refrigerant gas.
The goal is kept it more comfortable inside the house than it is outside.

4. Type of air conditioner
1.window air conditioner
2.poratable
3.wall hung split or multi head split systems
4.ducted air conditioner

5. 1.WINDOW A/C
A window air conditioner are one of the most commonly used and cheapest type of
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.
Easy to install. mobility and shifting.
Costs lesser in comparison to other varieties.
Single unit with compressor and condenser.

7. 2.PORTABLE AC
Portable air conditioner as its name implies means that this type of air conditioner is movable
although some work such as installing the exhaust tube and locating a suitable power point
need to be done. Most design will include caster wheels to increase the mobility of the unit.

9. 3.wall hung split or multi head split systems
A split air conditioner is suitable alternative to wall , window or centralized air
conditioner systems.
The two sections are connected with a set of electrical wires and tubing used to
transport air between the two sections.

11. Ducted air conditioner
The purpose of air conditioning ductwork is to deliver air from the fan to the
diffusers which distribute the air to the room.
Air moves through the ductwork in response to a pressure difference created by the
fan.
