Dear All,
I selected Danfoss SC21G compressor for a refrigeration application. At 0 Deg. C evaporating temeperature, it will give 1268 Watts cooling capacity, it is sufficient for my application. The refrigerated space temperature required is +5 Deg C. As per compressor catalogue, the displace ment volume is 20.95 cubic CM, Maximum refrigerant charge is 1300g and Free gas voulme in compressor is 1460 cubic CM. Suction and discharge connector ID are 10.2 and 6.2 mm repectively. From these data, how I will size a (forced) air cooled Finn and tube evaporator? (the guy who makes evporator coil need only physical size, not the capacity required). Fan details: 97 cfm, Power: 22 Watts. Expansion device: capillary tube.I have to design a custom fabricated evaporator for this cooler.The material for evaporator is copper tube and aluminium fins. Fin spacing: 5 fins per inch. Can any one help me, please?
With thanks in advance,
Cheers,
Rayin
