Some "hot gas" defrost systems reheat the refrigerant just prior to its returning to the compressor for what purpose?

🔍 Key Concepts

• Hot-gas defrost operation in a refrigeration system • What happens if liquid refrigerant reaches the compressor • Difference between gas and liquid returning on the suction side

💭 Think About

• Think about what condition the refrigerant should be in when it reaches the compressor suction to avoid damage • Ask yourself what physical damage might occur inside a compressor if significant liquid (instead of vapor) is drawn in • Consider whether reheating the refrigerant just before the compressor would create more liquid or more vapor in the suction line

✅ Before You Answer

• Verify what liquid slugging means in relation to compressor operation • Check whether reheating the refrigerant before the compressor would help or hurt the expansion valve operation (which is on the high-to-low pressure side) • Confirm if increasing the circulation of liquid refrigerant is desirable right before the compressor, or if we usually want mostly vapor there

Question 1 of 27070
