Title : Mini Cold Storage Performance With Diesel Motor As a Compressor Driver

Abstract :

The purpose of this research is to determine the performance of mini cold storage with three rotational variation of diesel engine which are 650 RPM, 700 RPM and 750 RPM, temperature of mini cold storage room reached -20 ºC, initial product temperature 28ºC, the final temperature of the product is -5 ºC, the evaporator temperature is -29 ºC and the condenser temperature is 32 ºC to 34º C. The results shows that in the 650 RPM, the fuel consumption is 13,200 milliliters with a total operating time of 22 hours, for refrigeration capacity of 1,304 kW, refrigerant mass flow rate of 0,0085 kg/s, compressor capacity of 0,35 kW, condenser capacity of 1,65 kW with COP value of 3,75. Whereas in the 700 RPM of diesel engine the total fuel consumption is 10,400 milliliters with a total operating time of 16 hours, for refrigeration capacity of 1,74 kW, the mass flow rate of refrigerant is 0,011 kg/s, compressor capacity is 0,45 kW, condenser capacity of 2.19 kW with COP value of 3,85. Furthermore, in the 750 RPM of diesel engine, the total fuel consumption is 13,300 milliliters with a total operating time of 19 hours, for refrigeration capacity of 1,483 kW, the mass flow rate of refrigerants is 0,00980172 kg/s, compressor capacity is 0,405007 kW, condenser capacity is 1.89 kW with COP value of 3,6. it was concluded that the use of a 700 RPM diesel motor produces the highest COP value (3.85) with efficient and effective fuel consumption (10,400 milliliter)
