🔍 Key Concepts

• Effects of leaking discharge valves on compressor efficiency and pressure differential • How suction (low side) pressure and discharge (high side) pressure influence pressure control switches • Difference between continuous running and short cycling in automatic refrigeration systems

💭 Think About

• What happens to the compressor’s ability to build and maintain high-side pressure if some of the compressed gas leaks back on every stroke? • If the high-side pressure cannot be maintained properly, what does that do to the low-side (suction) pressure and the low-pressure control? • Which control (low-pressure or high-pressure cut-out) is more likely to operate if the compressor is weak and cannot maintain a good pressure difference?

✅ Before You Answer

• Review how a low-pressure cut-out switch is wired and what condition it responds to (falling or rising suction pressure). • Review how a high-pressure cut-out switch operates and under what fault it will open the circuit. • Think about whether a weak/leaky compressor would make pressures too high or too low, and which condition would cause it to cycle on and off.
