Question 1 of 27070

The refrigeration system low pressure cutout switch is actuated by which of the following?

🔍 Key Concepts

• Refrigeration cycle components – condenser, evaporator, and suction line (compressor inlet) • What the low pressure cutout is protecting (especially the compressor) • Where system pressure will drop if there is a loss of refrigerant or loss of evaporator load

💭 Think About

• Think about which part of the system is at the lowest pressure during normal operation and is directly connected to the compressor inlet • If there is a refrigerant leak or the evaporator runs out of load, where would you expect pressure to fall first and most clearly? • Which measurement point would give the most reliable signal to shut the compressor down before damage occurs?

✅ Before You Answer

• Identify which choice is associated with the low side of the system (evaporator/suction) rather than the high side (condenser) • Eliminate any answers that deal with water-side pressures instead of refrigerant-side pressures • Ask yourself: which location’s pressure change is the direct trigger used to protect the compressor from running at excessively low suction pressure?
