Evaporators in Refrigeration Systems: Types, Design & Defrosting

EVAPORATORS

Introduction

Evaporators are heat exchangers designed to evaporate liquid refrigerant. The boiling temperature of the coolant is less than the temperature of the environment you want to cool. Refrigerant evaporates at low pressure, although higher than atmospheric pressure. The cooling efficiency of the liquid-vapor mixture depends on the liquid content in the mixture.

Types of Evaporators by Feeding Method

  • Dry expansion
  • Flooding

This classification is based on whether the facility contains

The term “object-oriented” combines “object” and “oriented.” Object-oriented programming (OOP) is a computer programming design methodology that models software design around data (objects) rather than functions and logic. The primary goal of OOP is to bind data and the functions that operate on them together.

Basic Concepts of OOP:

  • Inheritance
  • Dynamic Binding
  • Message Passing
  • Class
  • Objects
  • Encapsulation
  • Abstraction
