BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, those most common in a ....etc

BASIC REFRIGERATION PRINCIPLES
If you were to place a hot cup of coffee on a table and leave it for a while, the heat in the coffee would be transferred to the materials in contact with the coffee, i.e. the cup, the table and the surrounding air. As the heat is transferred, the coffee in time cools. Using the same principle, refrigeration works by removing heat from a product and transferring that heat to the outside air ....etc

EJECTOR refrigeration cycle of expansion (EERC)

SUMMARY
Expansion cycle ejector refrigeration (EERC) is a variant of the standard vapour compression cycle in what year the ejector is used to restore part of the work that would otherwise be lost in the expansion valve. In initial Testing consortium of poor performance, mainly due to the non-equilibrium thermodynamic conditions causes the ejector nozzle. The changes made to fix the problem and improve the performance of significant were found.

Air conditioning (often referred to as AC, A.C., or A/C) is the process of altering the condition of air by removing heat and humidity to achieve a more comfortable interior environments, typically with the aim of distributing the conditioned air to an occupied space such as a building or a vehicle to improve thermal comfort and indoor air quality. In common use, an air conditioner is a device that removes heat from the air inside a building or vehicle, thus lowering the air temperature. The cooling is typically achieved through a refrigeration ....etc

ABSTRACT
The ejector expansion refrigeration cycle (EERC) is a variant of the standard vapor compression cycle in which an ejector is used to recover part of the work that would otherwise be lost in the expansion valve. In initial testing EERC performance was poor, mainly due to thermodynamic nonequilibrium conditions in the ejector motive nozzle. Modifications were made t ....etc
