How subcooling increase the COP of vapour compression refrigeration?

Subcooling increases the efficiency of a vapor compression refrigeration system by ensuring that the refrigerant entering the expansion valve is in the liquid state and at a lower temperature than the saturation temperature, reducing the amount of flash gas that would otherwise form. This results in increased cooling capacity and improved COP (Coefficient of Performance) of the system.


What is Vapour absorption machine?

A Vapour Absorption Machine (VAM) is a type of refrigeration system that operates on the principle of heat absorption. It uses a refrigerant-absorbent pair to produce cooling by absorbing heat from a space and releasing it elsewhere. VAMs are commonly used in industrial applications and areas where waste heat or low-grade heat is available.


Why do you need to recharge the refrigeration system?

usually the refrigerant you have pumped out of the system is contaminated (either liquid/air) contaminated refrigerant is less efficiant and will lead to a short system life. refrigerant is works kind of like the rain in a water cycle. The system starts at the compresser (the heart of the system) pushing refrigerant in to the condenser (like condensation in the clouds) condensing to a liquid and heads toward the metering device (raining) The metering devise rapidly lowers the pressure of the system into the evaporator (get the picture already?) where the refrigerant collects the heat in the refrigerated space and boils into a vapour releasing it to out side the refrigerated space. obviously there is more detail then this but thats the basic operation.


What do you mean by condenser airside pressure drop?

Condenser airside pressure drop refers to the decrease in pressure that occurs as air passes through the condenser coils in an air conditioning or refrigeration system. This pressure drop is influenced by factors such as the design and cleanliness of the coils, air velocity, and any obstructions that restrict airflow. A higher pressure drop can indicate reduced efficiency and performance issues in the system.


How does a cooler work?

There are two basic cycles of Airconditioning/Refrigeration 1. Vapour compression cycle, 2. Vapour Absorption Cycle Vapour compression cycle is used in most of the airconditioning applications but ofenly vapour absorption is used. evaporator, compressor, throateling valve, tank & condensor are the major parts of this cycle.

What role does a compessor play in a refrigeration system?

In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.

Why throttle valve is used instead of expansion cylinder in vapour compression refrigeration system?

In vcrs system there is a phase conversion system i.e. liquid state to gases state and this happens with latent heat of working medium but on the other hand there is only gases expansion on expander cylinder and no phase changes occurs and in cylinder we can not expend two phase system..


Why is the suction pipe of vapour compression refrigeration system insulated?

To minimize sweating of the air around the pipe. When the air comes in contact with a cool surface, its water vapor condenses!

What is vapour locking?

In the automobiles, in the fuel system,sometimes large amount of vapour formation takes place at higher temperature.The cause is evaporation of some of the more volatile components of the petrol. Bubbles of vapour from in the fuel system can prevent the easy flow of fuel. This is called vapour lock.
