Hydronic System Pressure Concepts

The video introduces ITT Industries' Little Red Schoolhouse, a learning center for hydronic and steam systems. It features a demonstration of a pump compression tank location, highlighting the importance of tank placement in relation to the pump. The video explains how pressure dynamics work in the system and demonstrates the effects of different tank locations on system pressure. Key takeaways include understanding the role of the pump and tank in maintaining system pressure and preventing issues like air binding and cavitation.

What is the primary purpose of the ITT Industries Little Red Schoolhouse?

• To provide general education to students

• To teach engineers about hydronic and steam systems

• To offer courses in computer science

• To train students in electrical engineering

What is the main function of the pump in a hydronic system?

• To decrease the system pressure

• To increase the temperature of the fluid

• To circulate the fluid within the system

• To change the proportions of air and water in the tank

How does the location of the tank affect the system pressure when connected to the pump suction?

• It increases the pressure at every point in the system

• It decreases the pressure at every point in the system

• It has no effect on the system pressure

• It causes the system to operate in a vacuum

What is the effect of connecting the tank closely to the pump charge?

• The pump increases the pressure at the suction

• The pump can change the pressure at the discharge

• The pump reduces the pressure at the suction

• The pump has no effect on the system pressure

What happens to the pressure at the pump discharge when the tank is connected to the pump discharge?

• The pressure increases significantly

• The pressure decreases significantly

• The pressure becomes negative

• The pressure remains the same as the tank pressure

What is the consequence of having an automatic air vent in an area with negative pressure?

• It increases the system pressure

• It has no effect on the system

• It sucks air into the system

• It releases air from the system

What is the role of the sight glasses in the demonstration?

• To display the air coming out of solution

• To indicate the pressure at different points

• To show the clarity of the fluid

• To measure the temperature of the fluid

What is the significance of the 1522 pump in the demonstration?

• It has a head less than the non-operating pressure

• It is used to change the proportions of air and water

• It is used to increase the temperature of the fluid

• It has a head greater than the non-operating pressure

What is the effect of a drop in pressure on air in the system?

• It causes air to dissolve in the water

• It causes air to come out of solution

• It has no effect on the air

• It increases the solubility of air in water

Why is it important to locate the tank at the pump suction?

• To increase the temperature of the fluid

• To prevent air from coming out of solution

• To decrease the system pressure

• To change the proportions of air and water in the tank
