Introduction Other International and European standards, as well as various national standards also address the following subject matter: Properties of refrigerant and lubricants Performance testing of systems including energy consumption (refrigeration, air conditioners, heat pumps, etc) and components Performance of refrigeration-related equipment (such as recovery, recycling, vacuum equipment) Performance testing of refrigerated display equipment, and refrigerated storage equipment Design, construction and selection of system safety devices (such as pressure relief and pressure limiting devices) Safety design, construction and selection of system components (such as vessels and pipes) Safety of appliances (such as domestic refrigerators and freezers, commercial refrigerating equipment, air conditioners, dehumidifiers and heat pumps) Testing of airborne noise levels of refrigeration, air conditioners, heat pump equipment Electrical safety of refrigeration, air conditioners, heat pump equipment Such standards can be obtained from the relevant standardization organizations: 4 www.iso.org - International Standardisation Organisation 4 www.cen.eu - Comité Européen de Normalisation 4 www.iec.ch - International Electro-technical Commission 4 www.cenelec.eu - Comité Européen de Normalisation Electrotechnique 12
Introduction Choose your chapter Throughout the lifetime of the equipment, a variety of activities are carried out by different personnel and accordingly, a range of knowledge is needed. The content of this manual is intended to provide a large portion of that, particularly for those who are involved in refrigerant handling. We have summarised the major activities involved during the start-of-life, operation and end-oflife stages of RAC equipment. For each of these activities, the most important chapters of this manual have been identified. Thus, any training course or technical guidance specifically for any one of these activities can be focused on the material within the corresponding chapters. The primary objective of this manual is to provide the reader with the appropriate background information to enable him/her to gain an adequate level of understanding related to the key topics addressed. The diagram on the next page summarizes the contents of this manual. 13
