The design and construction of s refrigerating unit is handled from the knowledge of the working principles of laws of thermodynamics.
The size of the containing vessel i.e the case as established to be of 45cm by 32 cm in dimension. The Angle iron mild steel to used in the fabrication and welding. The box case of two layers are fabricated. Plastic (cooler) box is then placed inside the upper part with the other parts of the refrigerator were brought in. they were all fixed onto a wooden base with all the connections (electrical) made.
The capacity of the refrigerator is based on the workdone by the compressor which is O.I hp in specification. The size of the components used are
i.Condenser: The size is 0.1hp and it is a plate type condenser with extended surface.
ii.Compressor: The size is 0.1hp (75 watts)
iii.Copper wire: it is of 0.5cm in diameter and the total copper wire length is about 600cm (1½ roll)
The introduction of cooling fluid and filling of the compressor enabled the compressor to start functioning when connected to electricity using a 13 AMP rated socket
The interior of the plastic box is lined with dominium box with tubes arranged in convolution around it. This world effectively and cooled the water dropped into it. It compares favorably with the ones in the market.

ABSTRACT Distillation unit is the judgment used for the separation of liquid mixture depending on the volatility of the component. It has the top section and bottom section. In the top section this is where more volatile component goes and the bottom section is where the divider or less volatile component... Continue Reading
ABSTRACT A table top liquid-liquid extraction unit was constructed. The project also involved the repair and servicing of peristaltic suction pump, by painting it, replacing the connecting cord to the power supply, refilling of the work out suction plates, teeth and general servicing of the equipment. The glass absorption columns were provided as... Continue Reading
