In a Mechanical Refrigeration System the Refrigerant has the Maximum Temperature

By Mohit Uniyal|Updated : July 22nd, 2022

In a mechanical refrigeration system, the refrigerant has the maximum temperature at ____.

  1. Condenser
  2. Throttle valve
  3. Evaporator
  4. Compressor 

Answer: D- Compressor

In a mechanical refrigeration system the refrigerant has the maximum temperature at the compressor.

Solution:

A vapor compression refrigeration cycle includes the following processes

Compression : 

From 1 to 2, the superheated vapor from the evaporator enters the compressor, and its pressure and temperature increase due to the compression. In a mechanical refrigeration system, the refrigerant has the maximum temperature at the compressor. 

Condensation : 

From 2 to 3, the pressurized and superheated gas from the compressor moves to the condenser and releases heat into the atmosphere.

Throttling Process: 

From 3 to 4, the high-pressure liquid refrigerant is expanded from high pressure to lower pressure isenthalpically and the temperature of the refrigerant drops and goes to the evaporator.

Evaporation : 

From 4 to 1, the low-pressure liquid refrigerant absorbs heat from its surrounding environment and evaporates into a gas. The refrigerant is slightly superheated at the outlet of the evaporator.
