Every time you turn on the heating or air conditioning system air flows in through supply ducts and out through return ducts.

Now as awesome as Seattle is its one of the most humid cities in the country with an average relative humidity of 733. Pressure drop takes place in the duct due to the friction losses and sudden direction changes. A great majority of metallic ducts is made of galvanized steel.

Today a sheet metal fabrication shop would commonly fabricate the galvanized steel duct and insulate with duct wrap prior to installation. Flexible ductwork needs to be properly secured and supported ensuring kinks. They are a key component of air-conditioning systems for large buildings although they typically use more energy than any other piece of equipment in large buildings.

A typical AHU consists of. Air-duct Design for Mechanical Engineering helps you for every Mechanical Engineering entrance exam. It is similar to an air-conditioning system in that it is compressor based but a chiller cools liquid whereas an air-conditioning system cools air.

Usually rectangular ducts are preferred with. It is best suited to confined spaces where rigid structures can often be hard to install or at the ends of a rigid ducting network to connect it to the air outlet. Function of duct is to convey the air between two points.

Other metals used under special circumstances are copper and stainless. HVAC System-This stands for Heating Ventilation and Air Conditioning. Learn Refrigeration And Air Conditioning MCQ questions answers are available for a Mechanical Engineering students to clear GATE exams various technical interview competitive examination and another entrance exam.

Fiberglass lined ducts. Polyurethane and phenolic insulation panels pre-insulated air ducts Traditionally air ductwork is made of sheet metal which was installed first and then lagged with insulation. Refrigeration Air Conditioning MCQ Questions Mechanical Engineering.

Mechanical Engineering students definitely take this Test. To convey the conditioned air between two points. If you keep your air conditioner well-maintained it should help lower indoor humidity.

Air conditioning ducts are classified as. However ductwork manufactured from rigid insulation panels does not need any further insulation and. Flexible ducts are usually tube-shaped made of a wire coil and covered with a bendable durable plastic that is surrounded by insulation.

Its a system of tubes that generally run through the attic that are used to circulate air throughout the home for your heating and air conditioning system. This type of ducting is often cheaper and easier to install. Air Handler Coils-These are also referred to as evaporator coils.

Refrigeration And Air Conditioning MCQ question is the important chapter for a Mechanical Engineering and GATE students. These AC ducts are large diameter tube like structures made up of a mixture of metal framework surrounded by flexible plastic and insulation. Aluminum ducts are light in weight but basic cost per pound is higher than galvanized steel.

Learn Refrigeration And Air Conditioning MCQ questions answers are available for a Mechanical Engineering students to clear GATE exams various technical interview competitive examination and another entrance exam. Lightweight efficient and easy to assemble CLIMAVER is adapted to any project. Other components are a reservoir recirculating pump evaporator condenser and a temperature.

It is still commonly used to making air ducts as they are strong and conductive. Air-duct Design mcq to study with solutions a complete question bank. This type of duct is common in office and commercial buildings as it dampens the sound of the air conditioner unit.

An air distribution system comprising various types of outlets for supply air and. Functions of a duct. The solved questions answers in this Test.

Ducts are defined as paths for supply air and return air. What makes this ductwork a good option is when dealing with tricky spaces where rigid ductwork isnt possible to install. Thats why galvanised iron or aluminium sheets are preferred for duct because they have smooth surface and thus offer less resistance to air flow.

It supplies air from handling unit to the room to be air conditioned. Air-duct Design quiz give you a good mix of easy questions and tough questions. 11 Large sized industrial air-conditioning plant are.

Function of an AHU is to transmit processed air from the air conditioning plant to the conditioned space and distribute it properly within the conditioned space. It is a component that is essential in producing cold air. Next in popularity in metal ducts is aluminum.

This mock test of Test. Basically its your air conditioning system. It is located inside the air handler The indoor HVAC Unit.

Power Engineering Chapter 128. A duct system that includes a supply air duct return air duct cooling andor heating coils humidifiersdehumidifiers air filters and dampers 2. Its also often used to attach non-flexible ductwork to an air supply outlet.

Option c 12Clapeyron equation is a relation between. However the fiberglass in these ducts can deteriorate and eventually release fiberglass particles into the air this is a major health concern especially with long-term exposure. An important consideration while installation of flexible ducting.

This contains 10 Multiple Choice Questions for Mechanical Engineering Test. These are sheet metal ducts like those described above that have internal or external fiberglass lining.
