A portable cold room storage was developed. The system was tested with different types of perishable crops under different temperatures. The system is made up of two units, one, the evaporating unit that is where the produce was stored; it is made up of steel material with 79mm by 45mm in length and breadth. While the second unit is the trolleys, the system consists of a control switch that is calibrated to suit any type of produce stored in the system. It contain a separate basement which consist of compress or, 1/6 cooling fan 1/6 connected together into the evaporating unit. This system was also constructed with lagging material which consists of A and B formula called polytherine. The ambient temperature was 35o which have temperature range between30. The electricity power requires running the cold room storage system is 220 to 250v. Hence, the system is effective for the storage of perishables at favourable conditions for every home.
