The compressor provides the conversion of energy that is used in circulating the refrigerant round the circult.
The
crankshaft drives the piston through the connecting rod and it’s moved
by the tongue produced by electric motor. The pumping effect of the
piston produces the high pressure on the refrigerant which sets it in
motion. In the causes of circulation and attendant change of state the
refrigerant returns to the initial state and ready for another cycle.
In
a deep freezer the condenser performs function similar to that of the
radiator in an auto mobile. It cools the hot refrigerator gas by giving
out hear to the dryer which traps moisture that can block the metering
device. The liquid refrigerant passes through the metering device
which expands the liquid into the evaporator pipe which is of large
cross sectional area.
The pipe is laid on the inside of the deep freezer
A lot of insulation is done to isolate the refrigerated space from the surrounding its heating effect.
WHAT PROMPT THE PROJECT:
Looking
into the present situation of things the menace caused by road side
craftsmen who tends to spoil other progress in pretence to repairing
or constructing of deep freezer so that they will enrich their pocket
and then gives out fake freezers that will last for few months we then
decided to embark on this project.
PURPOSE OF THE PROJECT:
The purpose or objective of the project is to achieve the following
1.
Designing and constriction of a portable domestic cooling equipment
that would improve on existing design taken into consideration.
2.
Designing and constructing a cooling / freezing system that is
efficient with little or no complexity in maintenance.
3. Improving the designs and construction of cooling freezing equipment with a reduced weight.
4.
To design and construct a cooling equipment that will be mobile
economical and cost that a common man can afford.
IMPORTANCE OF THE PROJECT
The
project is designed to accomplish a fast freezing system without
destruction of bottles at very low temperature it is designed in such a
way that the freshness and nutrient of food material is refined.
It is based on reduced weight cost fast freezing techniques compactness longer life span also to improve on existing designs.
BENEFIT OF CTHE PROJECT
Road
side craftsmen that enrich their pockets instead of satisfying the
consumers will be eliminated food stuff can be preserved for a very
long time.
