A PROJECT PRESENTATION ON
PORATABLE AIR CONDITIONER CUM
REFRIGERATOR
INTRODUCTION
Refrigeration may be defined as the process of achieving and
maintaining a temperature below that of the surroundings, the
aim being to cool some product or space to the required
temperature.
Refrigeration systems are also used extensively for providing
thermal comfort to human beings by means of air
conditioning.
NECESSITY
Because of their easy maneuverability,
relatively small size, and portability, portable
ACs are ideal for a variety of settings,
including apartments, rooms, workplaces,
computer server rooms, or anywhere else
where installing a traditional AC may not be
feasible.
OBJECTIVE
When we need to efficiently cool a small space such
as a bedroom or office, a portable air conditioner is a
great choice because it can solve the cooling
challenge by lowering the temperature in a given
environment.
Here is a general overview of how a portable air
conditioner works and its benefits.
CARNOT CYCLE
SYSTEM DEVELOPMENT
An air conditioning cum refrigeration system
consists of single compressor, single condenser, a
refrigerating evaporator and an air conditioning
evaporator.
This unit is useful in both household as well as
automobiles.
Specifications
Hermetic Compressor
90 liters capacity
made by whirlpool
SELECTION OF EQUIPMENT
Hermetic Compressors
Condensers - Air-cool condensers
Cooling Coils (Evaporator)
Expansion valve: Capillary tube
Fan and Blower: (60 watt, 0.35 A/1300 RPM)
Refrigerant: R-134a
ThermostatDrier and filter
Thermal Insulation
PERFORMANCE ANALYSIS
ADVANTAGES
One of the main benefits of a portable air conditioner cum
refrigerator is the fact that it can be moved from room to room
Portability- It includes rolling casters.
Therefore, you can provide cooling comfort to any area with
ease. and does not need to be permanently installed.
Portable air conditioners cum refrigerator are oftentimes more
affordable than traditional units and will usually not incur
installation costs
Portable air conditioners cum refrigerator do more than just
cool.
Affordable - Portable air conditioners cum refrigerator are
oftentimes more affordable than traditional units and will
usually not incur installation cost.
Limitation
Since only one refrigerant is used throughout the system, the
refrigerant used should have high critical temperature and low
freezing point.
The operating pressures with a single refrigerant may become
too high or too low. Generally only R12, R22 and NH3 systems
have been used in multi-stage systems as other conventional
working fluids may operate in vacuum at very low evaporator
temperatures. Operation in vacuum leads to leakages into the
system and large compressor displacement due to high specific
volume.
5.CONCLUSION
The present invention provides an air-conditioning
cum refrigerator designed to satisfy the need.
The scope of refrigeration is very wide and
applications are very diverse and literally
thousands of scientists and engineers have
contributed towards its development
One of the efforts towards this accomplishment is
compatible A.C. cum Refrigerator which can be
used for refrigeration as well as air conditioning
