Evaporator Controller - EKE 400 Industrial Refrigeration industrial engineering

The video tutorial explains the complexity of industrial refrigeration systems and the importance of controllers like the EKE 400. It covers the components of a single stage system, focusing on the evaporator circuit and its cooling process. The tutorial details the defrosting process using hot gas and the role of various valves. It also guides on installing controllers, connecting them to system components, and optimizing system operation. The video emphasizes the need for efficient communication and control of system parts to ensure effective and efficient operation.

What is one of the main challenges in controlling industrial refrigeration systems?

• Balancing effective and efficient operation

• Increasing the complexity of valves

• Reducing the number of evaporators

• Ensuring the system operates only during the day

In a single-stage refrigeration system, what is the primary function of the evaporator?

• To absorb unwanted heat

• To separate liquid from vapor

• To condense the refrigerant

• To compress the refrigerant

What happens to the refrigerant as it absorbs heat inside the evaporator?

• It evaporates completely

• It changes into a liquid and vapor mixture

• It remains a liquid

• It turns into a solid

Why is defrosting necessary in refrigeration systems?

• To remove ice that decreases heat exchanger efficiency

• To prevent the refrigerant from evaporating

• To reduce the pressure in the system

• To increase the temperature of the room

During the defrosting process, what role does the high-pressure vapor refrigerant play?

• It compresses the refrigerant

• It melts the ice on the heat exchanger

• It separates the liquid from vapor

• It cools down the evaporator

What is the purpose of connecting solenoid valves to the controller?

• To manually control the valves

• To automatically control valve positions during cycles

• To increase the pressure in the system

• To reduce the number of valves needed

What is one benefit of using a controller in refrigeration systems?

• Optimal cooling mode and safety

• Manual control of all components

• Reduced design flexibility

• Increased installation costs
