Mechanical Refrigeration System
In refrigrasi mechanical vapor compression systems are a series of four main components: evaporator, compressor, condenser, and refrigerant flow control devices. Each component has a trait and its own function differently, but in an integrated and operate together will be able to move the thermal energy.
The impact of operating a refrigeration system on an object is, if picked up some of the energy contained in it, the temperature of the object will decrease. Conversely, because the refrigeration...
PLC (Programmable Logic Controller) - An Introduction
