Aux 2 Unit 8 Q3

1 / 6

Which part of the refrigeration system does the high pressure cut-out monitor?

C) The discharge line of the compressor

B) The suction line

D) The evaporator inlet

A) The expansion valve

2 / 6

Why might a high pressure cut-out be triggered in a refrigeration system?

D) High refrigerant flow rate through the expansion valve

A) Low refrigerant charge

C) Excessive lubrication in the compressor

B) Blockage or insufficient airflow in the condenser

3 / 6

Which of the following is a reason for the operation of a high pressure cut-out in a vapor compression refrigeration system?

A) To prevent the refrigerant from evaporating too quickly

D) To increase the load on the condenser

B) To protect the compressor from damage due to excessive discharge pressure

C) To decrease the cooling efficiency of the system

4 / 6

What is another reason for the activation of a high pressure cut-out in a refrigeration system?

C) To regulate the temperature of the refrigerant

B) To prevent potential damage to the condenser

A) To ensure the system operates at a lower power setting

D) To reduce the noise level of the system

5 / 6

How does the high pressure cut-out operate in a vapor compression refrigeration system?

A) It adjusts the refrigerant flow rate to reduce pressure

C) It stops the compressor when the discharge pressure exceeds a set limit

D) It activates the evaporator fan to reduce system pressure

B) It automatically resets after a cooling period

6 / 6

What happens after the high pressure cut-out is triggered in a refrigeration system?

B) The cut-out must be manually reset to resume operation

D) The condenser fan switches to a higher speed to reduce pressure

C) The compressor runs at a lower speed until the pressure normalizes

A) The system resumes operation without any intervention
