aev [14]

Answer:

Isobaric process between points 1 and 2 while isochoric process between 2 and 3.

Explanation:

A themodynamic equilibrium system which changes from initial state to the final state by a process is known as thermodynamic processes. There are many different kinds of thermodynamic process which depends upon the thermodynamic quantities such as pressure, volume, temperature, entropy etc. The most common thermodynamic processes are isobaric, isothermal, isochoric and adiabatic.

When the temperature of the system remains same during the thermodynamic process, the process is known as isothermal.

When the heat of the system remains same during the thermodynamic process, the process is known as adiabatic.

When the volume of the system remains same during the thermodynamic process, the process is known as isochoric.

When the pressure of the system remains same during the thermodynamic process, the process is known as isobaric.

According to the question, between points 1 and 2 pressure remains constant, hence the process is isobaric.

According to the question, between points 2 and 3 volume remains constant, hence the process is isochoric.

When the liquid line is restricted, the supply of refrigerant to the metering device is reduced. What is the effect on suction p
Nimfa-mama [501]

Answer:

The suction pressure decreases and the superheat increases when the liquid line is restricted and the supply of refrigerant to the metering device is reduced.

Explanation:

1. The five components of refrigeration are:

  • Fluid refrigerant
  • Compressor
  • Condenser coil
  • Evaporator coil
  • Expansion device.

       The compressor limits the vapor released by the refrigerant. This            

       causes a rise in pressure (in refrigerant), which then pushes the  

       vapor into the coils on the outside of the refrigerator.

2. Now when the cooler air meets the warm gas present in the coils, it

   gets converted into liquid form.

3. Thus, when the liquid form is at high pressure, the refrigerant then  

   cools down as it flows through the coils placed in the fridge ( in both

   freezing and normal sections).

4. The refrigerant also absorbs the warm air present in the fridge, which  

   causes it to evaporate and flow back through the compressor and the

   cycle repeats in the same form.

Thus, when the liquid line is restricted and the supply of refrigerant to the metering device is reduced it causes a decrease in suction pressure and an increase in superheat.
