It is important that traps are incorporated into pipework systems to prevent liquid refrigerant draining back to the compressor(s) during off cycles, and to aid oil return to compressors during run cycles. This particularly applies where vertical pipework is involved. ?? Liquid Traps: On vertical discharge pipe runs, it is usual to take the pipework to the highest point of the condenser before returning to the inlet connection of the condenser. This ensures any liquid from the condenser does not drain backwards down the discharge onto the cylinder head of the compressor(s) during off cycles. Another method of eliminating this problem is to fit a check valve in the discharge line at the lowest point after the pipework leaves the compressor. ?? Oil Traps: Oil traps are installed in suction lines to ensure oil return to the compressor(s), they are usually installed at the ends of vertical risers Read more: https://lnkd.in/dX9QBwZF Federation of Environmental Trade Associations (FETA) Institute of Refrigeration UK

T-Levels can be a useful pathway for future employment. If you would like to know information about the T-Level route, The Department for Education has useful guidance for providers online. You can find it here: https://lnkd.in/d_9NnxTN Federation of Environmental Trade Associations (FETA)

Refrigerant Pipework - Sizing It is very important that pipe sizing calculations are carried out. Selecting pipes according to the connection sizes on compressors and other components will not guarantee the best design. These connections are sized to suit a wide range of applications, but will not be correct for every installation. Charts and software which give pressure drops for a given refrigerant and system capacity over a range of evaporating or condensing temperatures are available from a number of sources.

Would you like to become a competent refrigerant engineer but unsure the route to take? Some of the steps you can take to acquire the necessary training and qualifications include: ? Pursue a T-Level in Building Services ? Pursue a diploma in refrigeration and air conditioning engineering ? Apply for apprenticeship programs offered by reputable organisations specialising in refrigeration engineering ? Obtain professional qualifications - You can work towards achieving the City & Guilds Level 2 and Level 3 qualifications in refrigeration and air conditioning Don't forget to keep up with industry updates, attend workshops, seminars & more. The BRA provides a useful blog that can help you to choose the best pathway suited to you: https://lnkd.in/e9fQx-3j Federation of Environmental Trade Associations (FETA)

Pipework should be selected to minimise pressure drop. The effect of pressure drop on performance and efficiency is more significant in suction lines than in other pipework. ?? A relatively small pressure drop in the suction pipework of a low-temperature installation will cause a serious reduction in the system’s efficiency. ?? A pressure drop in a discharge line will have no significant effect on efficiency. ?? As the pressure ratio of a system decreases, so does the effect of a suction line pressure drop.

Refrigerant Pipework Pipework should be sized taking into account the following factors: 1?? Pressure drop 2?? Oil return to the compressor 3?? Minimum refrigerant charge 4?? Liquid refrigerant control 5?? Prevention of vapour locks 6?? Low noise 7?? Flexibility over entire operating range 8?? Minimum heat pickup Some of these parameters are dealt with elsewhere in the guide. Oil return, refrigerant charge and noise are covered here. Read more about each factor from page 24 in the 'Guide to Good Commercial Refrigeration Practice Part 2: System Design and Component Selection' here: https://lnkd.in/dX9QBwZF Institute of Refrigeration UK Federation of Environmental Trade Associations (FETA)

You can read BRA's thoughts on key developments in the refrigeration sector in the 2024 FETA Review - worth checking out!

This document is the Best Practice Guide for the Code of Conduct for carbon reduction in the retail refrigeration sector (the Code). Each chapter contains an introduction to the working group, explain the key issues addressed and the scope of the best practice advice, followed by a set of recommendations. This Guide should be used in conjunction with the Code’s Technical Specification document, which provides further information and signposting for all of the references assigned to the best practices.

Guidance on Storage of A2L refrigerants This document has been written by a subgroup of the FETA A2L Working Group as a signpost guidance document following members questions about storing A2L refrigerants (both contractors and wholesalers). The information covers a practical approach to storing all cylinders used by the refrigeration industry, including A1, A2L and A3 refrigerants together with other products. It is intended to supplement a location specific risk assessment with helpful information, not replace it.
