What is the duct in electrical motor?
In an electrical motor, the duct refers to the passage or channel that facilitates the flow of air for cooling purposes. Proper airflow through the duct helps dissipate heat generated during the motor's operation, ensuring efficient performance and longevity. Additionally, ducts may also be designed to direct air towards specific components to enhance cooling efficiency. Overall, the duct plays a crucial role in maintaining optimal operating temperatures within the motor.
What is the duct aspect ratio in HVAC?
The duct aspect ratio in HVAC refers to the ratio of the duct's width to its height. It is a critical factor in determining airflow efficiency and resistance within a duct system. A higher aspect ratio typically indicates a narrower, taller duct, which can affect airflow characteristics, noise levels, and pressure drops. Maintaining an optimal aspect ratio helps ensure effective ventilation and energy efficiency in heating, ventilation, and air conditioning systems.
Roughly how much does it cost to install central heating in a 3 bedroom bungalow?
There is no answer to that, does the house need some demo to install the duct work or a lot? Are there beams or obstructions in the way?Even the costs of heating units vary a lot. Your best choice is to phone a few heating companies and get them to come in and give you a free estimate, takes all the guess work out of it.
Why the return duct of AHU is larger than supply duct?
The air is returning at a lower velocity, so you need a larger size duct.
What is the R value of duct board?
1" Duct Board has an R-Value of 4.3
What are the benefits of using insulated duct work in a heating and cooling system?
Insulated duct work in a heating and cooling system helps to prevent energy loss, improve efficiency, reduce noise, and maintain consistent temperatures throughout a building.
Bus bar and bus duct sizing calculations?

What does RA mean on a floor plan?
I think it means "return air" - a duct for a ducted heating and/or cooling system
What is the purpose of an air duct cleaner?
The purpose of an air duct cleaner is to clean the heating and cooling system components of forced air cooling in one's house. It is done so that there is less indoor pollution and a lower level of contamination.
What is the formula for duct sizing?
To calculate the formula for duct sizing divide the room load by the whole house load. Next multiply those results by the equipment CFM.
What are the advantages of using a split duct heat pump for heating and cooling in a residential setting?
A split duct heat pump offers energy efficiency, cost savings, and the ability to provide both heating and cooling in a residential setting. It also allows for individual temperature control in different rooms, making it a versatile and convenient option for homeowners.
What is air duct cleaning?
Air duct cleaning is a professional cleaning service that removes debris and contaminants from inside the air ducts as well as from mechanical components of the heating and cooling units of the HVAC system.
What type of cleaning services does the company Duct offer?
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing. A1 Air Duct in Dallas offers Duct Cleaning Services at affordable prices.
What is the purpose of a starting collar duct in HVAC systems?
The purpose of a starting collar duct in HVAC systems is to connect the main ductwork to a branch duct, allowing for the distribution of air to different areas of a building. It serves as a starting point for air to flow into the branch duct, ensuring efficient and effective heating or cooling throughout the space.
What are the benefits of using a duct fan booster in a ventilation system?
A duct fan booster can improve airflow in a ventilation system, leading to better air circulation and more efficient cooling or heating. This can help reduce energy costs and improve overall air quality in a building.
Air temperature difference inside the duct?
The air temperature difference inside a duct refers to the variation in temperature between the air entering the duct and the air exiting the duct. This temperature difference is influenced by factors such as the heat gained or lost through the duct walls, the efficiency of the HVAC system, and any insulation present in the ductwork. Monitoring and optimizing this temperature difference is important for ensuring effective heating or cooling of the space.
Where is wet bulb temperature measured in the heating mode?
Wet bulb temperature is measured as part of the air temperature when a heater is running. It is measured at the return air grille (near the return air duct) or at the supply air grille (near the supply air duct). It is important to measure wet bulb temperature in the heating mode because it indicates the amount of moisture in the air and helps to determine the amount of cooling or heating that is needed. Wet bulb temperature is measured at the return air grille.Wet bulb temperature is measured at the supply air grille.Measuring wet bulb temperature in the heating mode helps to determine the amount of cooling or heating needed.
