A refrigeration plant works on aqua-ammonia absorption system. Heat is supplied to

the generator by condensing steam at 200 kPa with 90% quality. The temperature

to be maintained in the refrigerator is −10 ◦C. The ambient temperature is 30 ◦C.

Estimate the COP of the refrigerator. If the actual COP is 50% of the maximum

COP and the refrigeration load is 2 TR, what will be the required steam flow rate?
