The aim of this project is in the title – zero refrigerant loss. The project offers practical assistance to everyone involved in purchasing, designing, installing, servicing, maintaining and owning refrigeration equipment to help them reduce leaks.  \n\n| 1 | Introduction – why leaks matter | Page 2 |\n| --- | --- | --- |\n| 2 | Leak testing | Page 3 |\n| 3 | Getting the best from your electronic leak detector | Page 3 |\n| 4 | Pressure testing to find leaks | Page 4 |\n| 5 | Leak test procedure | Page 5 |\n| 6 | Reducing leakage and common leak points | Page 6 |\n| 7 | Refrigerant charging | Page 7 |\n| 8 | Records | Page 7 |\n| 9 | F Gas record sheet | Page 8 |\n| 10 | Useful information | Page 9 |\n\nA leak of 1 kg of refrigerant causes approximately the same environmental damage as driving a van 10,000 miles.  \nGuide to good leak testing  \nCommercial and industrial refrigeration and air conditioning systems leak too much refrigerant – leaks of up to 30% of the charge during a year are not uncommon. Leak rates do not have to be this high. Adherence to best practice in service, maintenance leak testing and repair can significantly reduce refrigerant losses. This guide shows you how.  \nIn this guide, key points are highlighted and include this symbol: Anything which is a legal requirement is in italic text.  \n1. Why leaks matter  \nIncreases costs – service, refrigerant, electricity, downtime  \nIncreases adverse climate change – the “direct” effect  \nReduces system efficiency  \nIncreases power consumption  \nIncreases CO2 emissions (at the power station)  \nIncreases adverse climate change  \n– the “indirect” effect  \nThere is a legal obligation to reduce leaks and YOU are a key part of this  \nUnder the European Fluorinated Gas (F Gas) Regulations, we have to take measures to reduce leakage. These include:  \n• Leak testing systems once a year if the charge is between 3 and 30 kg and twice a year for systems with more than 30 kg.  \n• Logging refrigerant usage and leak tests / repairs.  \n• Being qualified to handle refrigerant.  \nThere is more detailed information on legal requirements throughout this guide.  \nIt is illegal to top up a system with refrigerant without first finding and  \nrepairing the leak(s) .  \n2. Leak testing  \nThe table below lists the three most effective methods for finding refrigerant leaks:  \n\n| Method | Effectiveness | Compliance |\n| --- | --- | --- |\n| Leak detection spray / soapy water | Good for pinpointing leaks. | Allowed under the F Gas Regulations. |\n| Electronic leak detector | Good for most leaks if the detector is used and maintained correctly (see Section 3 below) . Make sure your detector is sensitive to the refrigerant type you are testing. | Allowed under the F Gas Regulations – the leak detector must have a sensitivity of 5 g/year and should be checked annually. |\n| Fluorescent additive (injected into the system with oil and detected using an ultra violet lamp) | Can be an effective maintenance tool for quick leak testing. Can be messy. The additive must be cleaned off after a leak. Coalescent oil separators remove the additive so it does not circulate in the pipe work and components between the oil separator discharge and compressor suction. | Allowed under the F Gas Regulations if approved by the equipment manufacturer – the use of the additive voids warranty on some compressors. |\n\n3. Getting the best out of your electronic leak detector  \nElectronic leak detectors are test instruments which need to be looked after, checked and maintained to ensure accuracy. Under the F Gas regulation it should be checked once a year. This is a minimum requirement – for optimum reliability they should be checked more frequently, e.g. after 25 hours use.  \nAvoid contaminating the detector with oil, and replace the filter (where fitted) regularly.  \nThere are two types of l","cbCaimvLULRnq1Ux","https://ap.wps.com/l/cbCaimvLULRnq1Ux","pdf",266468,"English","# Introduction – why leaks matter\n# Leak testing\n# Getting the best from your electronic leak detector\n# Pressure testing to find leaks\n# Leak test procedure\n# Reducing leakage and common leak points\n# Refrigerant charging\n# Records\n## F Gas record sheet\n# Useful information","[{\"question\":\"Why do refrigerant leaks matter for systems and the environment?\",\"answer\":\"Refrigerant leaks increase service, refrigerant, electricity costs and downtime, reduce system efficiency, and raise power consumption and CO2 emissions.
