| The designed semi-automatic controlled atmosphere storage facility for calamansi (Citrofortunella microcarpa) was developed with the application of vapor compression refrigeration engineering principles and arduino system to lengthen the fruit shelf-life for commercialization and processing purposes. The prototype's overall dimension is 210 cm in length, 120 cm in width, and 120 cm in height, and has a storage volume of 0.512 m3. It has a storage capacity of about 90-120 kilograms. The main components of the facility are the compressor, condenser, capillary tube, and evaporator as the main components. The arduino system includes temperature and RH, O2, CO2, N2 sensors, a humidifier, arduino uno board, relay switch, a power supply, a DC-AC converter, a GSM... |
