What is the effect of Evaporative Pressure

What is the effect of Evaporative Pressure

The evaporative pressure or suction pressure is an important factor that affects the performance of a vapor compression system. Let the suction pressure be reduced from P1 toP1‘ on the P-h diagram. Its effect will be. Decrease in refrigerating effect from (h1-h4) to (h1‘-h4) Increase in the specific volume of vapour from v1 to v1‘….

Uses of Flash chamber and Accumulator

Uses of Flash chamber and Accumulator

Flash chamber Flash chamber is an insulated tank. It is always fitted after the metering or throttling device but before the evaporator in a vapour compression refrigeration system. Need of flash chamber: It has been observed that the liquid refrigerant coming out from the expansion device contains some vapour refrigerant also. (normally vapour liquid mixture)….

What is the effect of undercooling/subcooling

Under cooling of the liquid refrigerant in the condenser is a normal practice, which ensures that the refrigerant will enter the expansion valve only in a liquid state. In actual practice, the high pressure and high-temperature vapor refrigerant from the compressor are cooled and liquefied when it passes through the condenser. The liquid refrigerant also…

What is the principle of vapour compression system?

What is the principle of vapour compression system?

PRINCIPLE OF WORKING OF VAPOUR COMPRESSION SYSTEM In this type, the vapors condense or evaporate within the working ranga of temperature of the refrigeration systems. Here the working agents undergo changes of state and heat changes are in the form of latent heat. Construction A schematic diagram of vapor compression system : The basic components…

How To Learn Refrigeration Evaporators

How To Learn Refrigeration Evaporators

The evaporator is the component of the refrigeration system in which the heat is removed from the air, water, or any other body by the evaporating refrigerant. It is a device in which the refrigerant is evaporated by absorbing the heat from a surrounding medium. CLASSIFICATION OF EVAPORATORS Based on the circulation Natural circulation evaporators…

How cooling tower system works?

How cooling tower system works?

COOLING TOWER Cooling towers are essentially water conservation or recovery devices. Cooling towers are the largest mass and heat transfer devices used extensively wherever water is used as a cooling medium as in the case of water-cooled condensers. Principle of cooling tower A cooling tower is heat-rejection equipment where the warm water from the condenser…

What is a condenser explain the type of condenser?

What is a condenser explain the type of condenser?

What is a condenser? The condenser is a part of the refrigeration system, which rejects the heat energy of the refrigerant gas gained in the evaporator and the compressor. Atmospheric air and water are the two most convenient heat sinks to which the heat can be rejected. There are three types of condensers namely Air…
