Refrigeration is the process of lowering down the temperature of the body than its surrounding temperature, by extracting an amount of heat from it.
Refrigeration and Air Conditioning
Refrigeration is the process of lowering the temperature of the body to its surrounding temperature, by extracting an amount of heat from it.
It is a very good field of heat and mass transfer, where the main aim is to provide effective comfort conditions to human beings. So, we discuss in this course the effective areas where an engineer whose domain is refrigeration and air conditioning can perform effectively.

Lessons
Evaporators
evaporator also a heat exchanger likewise condenser.
Compressor
Free PreviewThe main function of the compressor is to draw the vapors of the refrigerant from an evaporator so that a minimum temperature and pressure can be maintained in the evaporator.
Condenser
Condenser acts as a heat exchanger where it exchanges the heat of refrigerant vapor that is coming from the compressor, with some other external fluid which acts as a heat sink.
Expansion Devices
The main purpose of these devices in the refrigeration system is to reduce the condenser pressure to the evaporator pressure.
Refrigerants
Free PreviewA Refrigerant is a fluid which presents initially in the tubes of the evaporator of any refrigeration system.
Multi Pressure System
multi pressure system is the refrigeration system having more than 2 pressure lines on the T-s graph.
Complete Vapour Compression System
It is the most widely used among all the refrigeration system. In this system, refrigeration is obtained as the refrigerant evaporates at a low temperature
Gas Refrigeration Cycle
In the gas refrigeration cycle, the working medium is air. It means that the cycle is very much similar to the vapor compression cycle (VCRS) where ammonia, etc is used as a refrigerant (working medium).
Properties of Moist air
The moist air is a mixture of dry air and water vapour. It is also known as humid air.
Fans
Fans are the mechanical devices whose primary function is to ventilation and cools down the surrounding space by circulating the air.
Solar radiations
Solar radiation is continually valued as a result of its effect on living matter and the effectiveness of its use for useful purposes.
Refrigeration and air conditioning control system
Various control devices are used for economical and satisfactorily working of the refrigerating and air conditioning system
Design Conditions
For the better design and analysis of air conditioning systems, a suitable selection of inside and outside design conditions is required
Industrial Applications of Refrigeration and air conditioning
Free PreviewNow-a-days of refrigeration and Air conditioning has so many uses that they have become significant.
Food Applications of Refrigeration and air conditioning
Mechanical refrigeration technologies are invariably used in these processes, which contribute significantly to the environmental impact of the food sector through both direct and indirect greenhouse gas emissions.
Case Study: Carrier OptiClean™ Dual-Mode Air Scrubber & Negative Air Machine
