Check frequently for any leaks. If refrigerant levels drop, the system will operate less efficiently.
Many common refrigerants are powerful greenhouse gases. For instance, 1kg of the refrigerant R134a has a global warming potential 1,300 times greater than that of 1kg of CO2. Failure to fix leaks could neutralise any benefit of savings in CO2 through energy efficiency.
It is illegal to knowingly vent refrigerants. So, as soon as a leak becomes apparent, take action to find and repair it.
Keep your refrigeration system running effectively and economically by:
- Frequent inspections. The most common areas of leaks on a refrigeration system are joints, seals and other mechanical valves and glands. However, you should regularly inspect the entire system, especially pipework, for leaks.
- Check for bubbles. If your system has a liquid line sight glass, check this as well; if bubbles appear here it can be a sign that the system is leaking.
- Fix it. Repair any leaks as soon as possible and recharge the system with fresh coolant. Your refrigeration maintenance contractor will be able to do this.
