HISTORY OF REFRIGERATION

HISTORY OF REFRIGERATION- Chapter 1 by IIT Kharagpur 


This Pdf contains below 


Objectives of the lesson: The objectives of this lesson are to: 


1. Define refrigeration and air conditioning (Section 1.1)


2. Introduce aspects of various natural refrigeration methods, namely:

              a. Use of ice transported from colder regions (Section 1.2)
              b. Use of ice harvested in winter and stored in ice houses (Section 1.2)
              c. Use of ice produced by nocturnal cooling (Section 1.2.1)
              d. Use of evaporative cooling (Section 1.2.2)
              e. Cooling by salt solutions (Section 1.2.3) 


3. Introduce historical aspects of various artificial refrigeration methods, namely: 

             a. Vapor compression refrigeration systems,
                       
                      including i. Domestic refrigeration systems (Section 1.3.1.1)
                                     ii. Air conditioning systems (Section 1.3.1.2)
             b. Vapor absorption refrigeration systems (Section 1.3.2)
             c. Solar energy based refrigeration systems (Section 1.3.3)
             d. Air cycle refrigeration systems (Section 1.3.4)
             e. Steam and vapor jet refrigeration systems (Section 1.3.5)
             f. Thermoelectric refrigeration systems (Section 1.3.6),
             g. Vortex tubes (Section 1.3.7) 


     







            At the end of the lesson the student should be able to: 

1. Identify various natural and artificial methods of refrigeration 

2. List salient points of various refrigeration techniques

3. Name important landmarks in the history of refrigeration
