Refrigeration operates by the same principle as in air conditioning system in controlling the condensing temperature. In an experiment. the refrigerant was feed into an evaporator coil and compressors to increase the condensing temperatures more than the temperature of the heat sink. For three level of water flow rate, the condensed temperatures (in \"0} which are normally distributed have been recorded as shown in Table 2.1. Table 2-1 Condensed temperature (in C) for three level of water ow rate mmaammmammmm
