Beyond Blades: Types of Centrifugal Fans and Their Unique Applications
The Mechanical Engineer
Difference Between Fans, Blowers and Compressors Fans, blowers and compressors are used to move fluid or air. They are differentiated from each other by ASME based on the specific ratio (). Here, we will discuss about centrifugal fan which is ...
Thermodynamic Analysis of Vapor Compression Refrigeration Cycle
The Mechanical Engineer
Introduction Thermodynamic analysis was done on ideal vapor compression refrigeration cycle through the following example to evaluate its performance. A household refrigerator uses R-134a as a refrigerant. It operates on the principle of an ideal vapor compression refrigeration cycle. Evaporator ...
Refrigeration Capacity in tons
The Mechanical Engineer
Introduction Refrigeration means cooling a space to a temperature lower than the ambient temperature. Refrigeration capacity is defined as the rate of heat removal from space and it is expressed in terms of TR (Tons of Refrigeration). It is also ...
Vapor Compression Refrigeration Cycle
The Mechanical Engineer
Introduction Refrigeration means cooling the space to a temperature lower than ambient temperature. Vapor Compression Refrigeration Cycle (VCRS) is the basic working principle of most of the modern refrigeration systems (i.e. AC, fridges, chillers, air dyer units…etc). The cycle is ...
