Vapor compression cycle is a revolutionary technique in refrigerant systems. A vapour compressor is basically a condensing machine, which compresses and disposes the coolants, at the end of a cycle. It has been found that the vapor-compression refrigerant is more efficient than other refrigeration methods. It is one of the most common refrigerant cycles used today and is the best known method for cooling of commercial buildings and vehicles. During vapor compression cycle, a low pressure refrigerant gas is pumped in a manifold through a condenser. The gas gets cooled as it passes through a thin film evaporator and it is then discharged into the atmosphere through a valve. In this article, you will read more about the superheating in vapour compression cycle to assist you in making your selection.
A vapour compression cycle is a very simple yet efficient process which removes heat from liquid and condenses water vapour to water. In this process there are no complex principles. The principle behind this is known only to a few people. The vapour compression cycle is the removal of heat from the liquid by means of evaporation. Heat is removed from the surroundings through evaporation.
The principle of evaporation used in vapour compression cycle is based on the principle of enthalpy. In this principle, the higher the enthalpy of a fluid, the lower its freezing point. The lower the enthalpy, the lesser the discharge pressure. The vapour compression cycle uses a very effective cooling system using a low pressure refrigerant to remove heat from the liquid by means of evaporation. The discharge pressure associated with this is lower than the refrigerant density.
The condenser of a vapour compression cycle is designed in such a manner that the pressure drop at the end of the cycle is smaller than the enthalpy change in the fluid. The principle of using heat energy in the refrigeration systems is very similar to the use of condenser in the heat pump. The heat pump uses the principle of radiator. In this system a pipe is firstly placed inside the heat pump. Through the pipes, heat energy is absorbed and then the heat is emitted. The process of heat transfer is also the same as in the case of condenser.
The vapour compression cycle is used in many types of refrigeration systems including chillers, freezers, desuperheaters, steam rooms, air conditioners, ice-makers and liquid transportation systems. A very economical type of this is known as hot fluid refrigeration. This is a system where water is compressed in order to produce heat energy for refrigeration. In this article you will learn more about refrigeration cycle.
The vapour compression cycle is found to be quite efficient in the production of high temperatures. This happens when the heated liquid is passed through the evaporator. The temperature gas is absorbed and the process of evaporation takes place. Then the cooled liquid enters the condenser coil and returns to its normal state. There are two types of evaporator available in the market, namely, solid evaporator and semi-conductor evaporator. Find out more details in relation to this topic here:
