A refrigeration cycle operates between condenser temperature of + 27

A refrigeration cycle operates between condenser temperature of +27 °C and evaporator temperature of -23°C. The Carnot coefficient of performance of cycle will be

This Free PDF Notes contains important questions related to a refrigeration cycle operates between condenser temperature of + 27 for upcoming government exams. As you know that the cycle of refrigeration works with compressor. The refrigerant flows into the Compressor where it’s capsulized and pressurized. At this juncture, the refrigerant is a broiling gas. The refrigerant is furthermore propelled to the Condenser which turns the vapor into liquid and absorbs some of the heat. The refrigerant moreover proceeds to the augmentation stopcock where it expands, mislaying pressure and heat.

  • Question – A refrigeration cycle operates between condenser temperature of + 27 °C and evaporator temperature of- 23°C. The Cannot coefficient of performance of cycle will be
    • 0.2
    • 1.5
    • 5
    • 6
      • Correct Option is 5

The refrigerant nearing out of the proliferation valve is algid and crawling due to the loss of pressure. It enters the Evaporator in a fluent state where the commutation of heat takes emplacement therefore refrigerating the freight inside the refrigerator. As the gasconade cools down the freight, it absorbs the heat which turns it into a gas. The gas is likewise thrust agone into the Compressor where it can start the round anew. Today, we are sharing A refrigeration cycle operates between condenser temperature of + 27 evaporator temperature of -23°C question and Understanding the Refrigeration Cycle.

The Refrigeration Cycle Components

The refrigeration cycle predominantly involves the motion of refrigerant from one emplacement to the following and in nonidentical forms with the paramount thing of pulling down temperatures whether in a console, counterbalance or even cold room layout. The one main significance of mastering how your marketable fridge works is so that you extrapolate how to cleanse and keep up accoutrements effectively. For illustration, extrapolating that your fridge uses an air- cooled condenser will support you determine the ideational situation for your unit in order to make its work effortlessly and lower the energy consumption. By concluding the basics, exclusively furthermore can one completely advantage from their commercial refrigeration.
