Lubrication is the action of applying a substance such as oil or grease to an engine or component so as to minimize friction and allow smooth movement. What is the need

A leak is a small crack or holes through which the working fluid in the system can flow out of the intended path. What are the dangers of leak on a

Valves are mechanical devices that control the flow of fluids (liquids or gases) through pipes or passageways. Function of valves The functions of a valve are to : How are valves

Hey there, today we are going to talk about something that substantially changed the shipping industry down to its roots, and that is Lifeboats. The origin of the Lifeboat is quite

What is air conditioning? It is an electrical device which is used for maintaining temperature, moisture & quality of air in the interior of an occupied space or room. The primary

Humidity: Humidity is the amount of water vapour present in the air. Relative humidity: Relative humidity is the percentage of the total amount of water vapour present at a temperature and

You’re stirring a spoonful of sugar into your cup of tea. At first, it vanishes, dissolved into the liquid, leaving behind no trace of its crystal form. Have you ever wondered

Global warming is the continuously increasing temperature on the earth due to Greenhouse gases, like (carbon dioxide, methane, nitrous oxide, hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs)). This change has disturbed the climatic

Ozone layer: Ozone layer is a layer of O3 gases shielding us from harmful Ultraviolet (UV) rays, which come from the sun. This layer is present in the stratosphere. 98-99% of

Desirable properties of refrigerants are important for the efficient and safe operation of refrigeration and air conditioning systems. These properties can vary depending on the specific application and system design, but

Enthalpy is the total amount of heat energy in a thermodynamic system. We are understanding this cycle with the help of the temperature enthalpy graph. To understand this concept let 1

A refrigeration system consists of several components that work together to remove heat from a space or substance and maintain a lower temperature. These components play specific roles in the refrigeration

Refrigeration systems contain several safeties to protect against equipment failure, leaks, and other potential hazards. Here are some of the key safety features typically found in refrigeration systems:  Low pressure (Lp)

Processes involved in refrigeration: There are four different process involved in the main components of a refrigeration system. Working of the refrigeration system (VCRS): The air inside the room is sucked
