The critical pressure of a refrigerant is the pressure at which the liquid and vapor phases of the refrigerant become indistinguishable at the critical point. Beyond this pressure, any increase in pressure will not result in liquefaction of the vapor. The critical pressure is an important parameter used in refrigeration systems to determine conditions for efficient operation.

What does it mean by condenser back prrssure?

Condenser back pressure refers to the pressure at which the refrigerant exits the condenser in a cooling system. It is a critical parameter in determining the efficiency of the system and ensuring that the refrigerant is properly condensed back into a liquid state for optimal performance. A high condenser back pressure can indicate issues with the system, such as poor heat transfer or restrictions in the flow of refrigerant.


The function of the condenser is too increase refrigeration pressure lose the heat from the refrigerant add heat to the refrigerant reduce the fridge aration pressure?

The function of the condenser is to release heat from the refrigerant, causing it to condense from a gas to a liquid state. This process increases the pressure of the refrigerant.


Should refrigerants be operated at temperatures above or below their critical temperature?

The critical temperature of a refrigerant is the point at which it changes states. In a refrigeration scenario, this happens 2 times per cycle. The refrigerant is a liquid on the high pressure side, and below its critical temp. On the low pressure side it becomes a vapor (gas) and its above its crictal temp. So the answer is both, depending on what side of the system you are on.


Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?

Refrigerant pressure decreases in a refrigerant cylinder while charging with vapor because vapor has a lower density compared to liquid refrigerant. As vapor is introduced into the cylinder, it displaces the liquid refrigerant, causing the pressure to drop as the overall density of the refrigerant in the cylinder decreases.


What determines the pressure on the low pressure side of a refrigeration system?

The pressure on the low pressure side of a refrigeration system is determined by the refrigerant's temperature and the system's design. As the refrigerant absorbs heat in the evaporator, it vaporizes and its pressure decreases. The size of the evaporator, the amount of refrigerant flowing through it, and the efficiency of the system also affect the pressure on the low side.

What is the definition of critical Temperature of a Refrigerant?

the temperature which occupied to liquefy the gas at its critical pressure and critical volume ,it is represented by Tc. --------------------------------------------------------------------------------------------- Rafaelrz. The Critical Temperature of a fluid is the maximum temperature at which it's vapor form can be liquefied by increasing pressure. The pressure required in this case is the Critical Pressure of the fluid. At the same time the Critical Pressure of a fluid is the maximum pressure at which you can liquefy a gas by reducing it's temperature. The Critical Point of a fluid is the state of the fluid at it's critical temperature and pressure (The Critical State of the fluid), and the specific volume (m3/kg) or molar volume (m3/kmol) observed, is the Critical Volume (mass or molar). An interesting fact is that at the Critical State, the liquid phase and vapor phase at equilibrium show similar properties.


How do you change high temperature refrigerant and high pressure refrigerant in to low temperature refrigerant and low pressure refrigerant?

You cool it and run it through a metering devise.


What determines the temperature at which a refrigerant vaporizes?

The pressure and the specific refrigerant properties determine the temperature at which a refrigerant vaporizes. As pressure increases, the boiling point of the refrigerant also increases. Different refrigerants have different boiling points at different pressures.

When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?

Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant
