Question 1 of 27070

Concerning the charging of refrigerant into a vapor compression refrigerating system, which of the following is true?

🔍 Key Concepts

• High side vs. low side of a vapor compression system (where pressure is higher/lower and what components are there) • Differences between liquid charging and vapor charging (and what each can safely enter) • Risk of liquid slugging the compressor and how proper charging avoids it

💭 Think About

• Think about where liquid refrigerant normally exists in the system during normal operation and which side is safest to introduce it into • Consider what would happen if liquid refrigerant entered the compressor suction directly—what damage or problems might occur? • Ask yourself whether the receiver is always involved in charging, or only in certain phases or methods of charging

✅ Before You Answer

• Verify which side (high or low) contains liquid refrigerant during normal running conditions • Verify which side (high or low) contains mainly vapor refrigerant and is connected to the compressor suction • Check which charging practice minimizes the chance of liquid entering the compressor while still allowing efficient charging

Question 1 of 27070

Concerning the charging of refrigerant into a vapor compression refrigerating system, which of the following is true?

when charging as a liquid it should be to the high side only

when charging as a liquid it should be to the low side only

when charging as a vapor it should be directly to the receiver only

when charging as a liquid it may be to the low or high side
