The atomizer sprays the water will be cooled over the wet deck surface. The water trickles from the top to the bottom along the wet deck surface whilst air flows from the bottom to the top. The heat is transferred directly from the water to the air by convection and evaporation. The evaporated water volume is recorded. The airflow is generated by a fan and adjusted using a throttle valve.

 

The unit enables the students to study the Basic Principals of ice plant cycle within a short period. The test rig is designed for the study of thermodynamics of vapour Compression refrigeration cycle by way of demonstration and experimentation. It has a facility to measure various parameters for experimentation. Ice cans are kept in liquid tank, which is cooled by the refrigerant evaporator. As conventional ice plants take 12-24 hours to complete the cycle, this ice plant is specially designed to demonstrate process of ice formation to be complete within period of 4 hours and hence it is most suitable for laboratory use.

The present set-up has a facility to interface the system with computer which  enables  to  log  the  experimental  data  using  computer.  The educational software and data-logging package has been developed for unit. The software environment

 

base is of Labview of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by CL. Engineers. This software package provides a comprehensive educational software environment within which the investigations can be

performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

It consists of a stationary cylinder, a roller and a shaft. 

The shaft has an eccentric on which the roller is mounted. 

A blade is set into the slot of a cylinder in such a manner that it always maintains contacts with a sloter by means of a spring. 

The blade moves in and out of the slot to follow the rotor when it rotates. 

Since the blade separates the suction and discharge parts, therefore it is often called a sealing blade. When the shaft rotates, the roller also rotates the roller rotates so that it always touches the cylinder wall
