I am Sodipe W.R., a dedicated Basic Technology and Technical Drawing teacher with 10 years of teaching experience. I hold a Bachelor's degree in Electrical/Electronic Engineering and a Postgraduate Diploma in Education. Passionate about hands-on learning, I help students develop technical skills and a strong foundation in engineering concepts. Over the years, I have trained and mentored students in various technical fields, preparing them for future careers in engineering and technology.
Cooling towers overcome most of these problems and therefore are commonly used to dissipate heat from water-cooled refrigeration, air-conditioning, and industrial process systems. The water consumption rate of a cooling… Read More »Accessories of Refrigeration and Air Conditioning Systems
Concept of Psychrometry and Psychrometrics Air comprises of fixed gases principally, nitrogen and oxygen with an admixture of water vapour in varying amounts. In atmospheric air water is always present… Read More »Psychrometry and Air Conditioning II
In vapour absorption system the refrigerant is absorbed on leaving the evaporator, the absorbing medium being a solid or liquid. In order that the sequence of events should be continuous… Read More »Vapour Absorption Refrigeration

The basic functions of an expansion device used in refrigeration systems are to: Reduce pressure from condenser pressure to evaporator pressure, Regulate the refrigerant flow from the high-pressure liquid line… Read More »Expansion Devices & Types of Expansion Devices
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. This causes the refrigerant to absorb heat… Read More »Evaporator
Condensers and evaporators are basically heat exchangers in which the refrigerant undergoes a phase change. In condensers the refrigerant vapour condenses by rejecting heat to an external fluid, which acts… Read More »Refrigerant Condensers: Air cooled, Water cooled, Evaporative condensers
The compressor is the main moving component of the vapour-compression system. It provides the system with the force to draw the vapour from the evaporator, to force it into the… Read More »Compressors: Reciprocating, Rotary, Centrifugal & Hermetic
Air conditioning is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both… Read More »AIR CONDITIONING SYSTEMS
The refrigerant is a heat carrying medium which during the cycle in the refrigeration system absorbs heat from a low temperature system and rejects the heat to a higher temperature… Read More »REFRIGERANTS
A vapour compression refrigeration system is an improved type of air refrigeration system in which a suitable working substance, termed as refrigerant, is used. It condenses and evaporates at temperatures… Read More »Simple Vapour Compression Refrigeration System
In an air refrigeration cycle, the air is used as a refrigerant. The basic elements of an air cycle refrigeration system are the compressor, the cooler or heat exchanger, the… Read More »Air Refrigeration Cycle
