ABSTRACT:
Fruits and vegetables are vital agricultural produce for human
consumption worldwide. Post-harvest losses of vegetables and
fruits often occur due to lack of proper preservation methods.
This study aimed to develop, and validate a mini automatic
refrigerator specifically for storing fresh fruits and
vegetables. The automatic mini refrigerator after construction
has an estimated volume of 126,678.24 cm3 equivalent
to 127 Litres Component of Refrigeration unit consist of
Compressor, Condenser Coil, Expansion Valve, Evaporator Coil,
R600a Refrigerant and Digital Thermostat. The digital thermostat
has a Temperature measurement range of -50 to 110 °C and
accuracy of plus, or minus 0.2 °C, giving it the ability to
store fruit and vegetable at a temperature range 0 to12 °C. The
system runs on a 220- 240 Voltage power supply, 0.95 Ampere and
120 Watts while the rated frequency is 50 Hz. The choice of all
materials selected for this work was done on the basis of their
local availability, affordability. The refrigerator's
performance was evaluated based on its cooling capacity,
coefficient of performance (COP), and cooling rate. Results
showed a cooling capacity of 735 W, COP of 1.61, and cooling
rate of 15.33 W, indicating moderate to good efficiency. The
refrigerator's effectiveness in maintaining optimal temperature
and humidity levels makes it a valuable asset for reducing
post-harvest losses and improving food security. This innovation
has practical applications in reducing food waste, enhancing
produce quality, and providing economic benefits for farmers and
suppliers, particularly in rural or remote areas with limited
access to electricity.
