In the hot season, you may encounter the phenomenon of overheating of the engine temperature. What to do when faced with this situation? Join us to learn about Causes of Overheating and its solution. Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components. When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or if heat dissipation is poor, so that normally produced waste heat does not drain away properly. Overheating may be caused from any accidental fault of the circuit (such as short-circuit or spark-gap), or may be caused from a wrong design or manufacture (such as the lack of a ...

 As you know, a heat pump is a device that transfers heat energy from a heat source to a heated tank. Heat pumps are one of the most important and practical devices in the industry. This industrial device, in addition to important advantages, also has common problems. Join us to learn more about the problems of heat pumps . A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoir. Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one. A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. The most common design of a heat pump involves four main components – a condenser, an expansion valve, an evaporator and a compressor. The heat transfer medium circulated through these components is called refrigerant. The heating efficiency of ground-source and water-source heat pum...

In the previous articles, we talked about the boiler. In this article, we are going to talk about boiler parts . We will first have an overview of the boiler and its applications. Stay with us.  What is a boiler? A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Different types of boilers have many applications in domestic and industrial applications. Many manufacturing facilities can recapture energy by installing more efficient steam equipment and processes and applying energy management practices.  The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron. Stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stre...

 What do you know about heat exchangers and their types? As the name implies, heat exchangers are used to transferring heat. Read this article for a more complete explanation as well as a review of different types of heat exchangers . What is a heat exchanger? A heat exchanger is a system used to transfer heat between two or more  fluids .  Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is...

 In the previous articles, we talked about the HVAC system. In short, Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide  thermal comfort  and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC & R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). Now we are going to examine the components of  HVAC system . Join us. HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to b...

 What do you know about condensers? In short, a condenser is a cooling device, but what is the use of this device? Join us to take a closer look at the features and different types of condensers . What is a condenser? In systems involving heat transfer, a condenser is a device or unit used to condense a gaseous substance into a liquid state through cooling. In so doing, the latent heat is released by the substance and transferred to the surrounding environment. Condensers are used for efficient heat rejection in many industrial systems. Condensers can be made according to numerous designs, and come in many sizes ranging from rather small (hand-held) to very large (industrial-scale units used in plant processes). For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. read more types of condensers There are three other condensers used in HVAC systems: Water-cooled Air-cooled Evaporative Air-cooled Condenser Condense...

What do you know about semiconductors? In this article, we intend to introduce semiconductors and their applications. In the following, we will examine the types of semiconductors and express the Differences Between P-Type and N-Type Semiconductor . What is a semiconductor? A semiconductor material has an  electrical conductivity  value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave the opposite. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure. When two differently-doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions and electron holes, at these junctions is the basis of diodes, transistors and all modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near th...
