Question 1

Can I mix different refrigerants in a chiller?

Accepted Answer

No, you should never mix refrigerants. Different refrigerants have unique pressure-temperature relationships and chemical properties. Mixing them can cause oil breakdown, poor cooling, and compressor failure. If a retrofit is needed, fully recover the old refrigerant before charging a new one.

Question 2

What happens if I use the wrong refrigerant?

Accepted Answer

Using the wrong refrigerant can reduce cooling capacity and increase power use. It can also damage valves, seals, and compressors because of pressure mismatch or oil incompatibility. Always check the manufacturer’s specifications or consult experts like LNEYA before refilling.

Question 3

How often should refrigerant be replaced or refilled?

Accepted Answer

Refrigerant doesn’t wear out under normal operation. You only need to recharge it when there’s a leak or after system repairs. Regular leak detection and pressure checks help keep your industrial chiller refrigerant at the right charge level.

Question 4

Which refrigerant is best for energy saving?

Accepted Answer

HFO refrigerants and other low GWP refrigerants usually offer the best balance between energy efficiency and environmental impact. Their thermodynamic properties reduce compressor work and lower running costs. The best refrigerant for energy saving depends on your chiller type, temperature range, and local regulations. LNEYA engineers can help you evaluate the ideal option.
