Oil and Gas Management - Health and Safety
Oil and Gas Production Technology
Oil in Refrigeration and Air Conditioning Systems
‘Oil in Refrigeration and AC Systems’ is a free online course that begins by introducing you to the safety devices on refrigeration plants and compressors the single-stage vapour-compression refrigeration cycle as well as fluorocarbon refrigerants based on methane and ethane. The types of leak tests (such as using soap fluorescent dye and nitrogen) as well as electronic leak detectors (like ultrasonic heated diode heated electrolyte infrared and corona discharge) are also vital to your knowledge. This course will teach you about leakage rectification systems and the recovery of refrigerant gas as well as three basic methods of recovery (liquid vapour and push-pull). Cautions when charging gas in a reefer and refrigerant system as well as the procedure for charging ship’s manual will also be covered in this course. You will learn about the HVAC (heating ventilation and air conditioning) unit details of HVAC gauges types of manifold gauges (which include R410A R22 and R134a) as well as how to connect HVAC gauges to refrigeration. The difference between ozone depletion potential (ODP) and global warming potential (GWP) as well as alternative secondary and future refrigerants will also be explained.Do you know how air and oil are handled in a refrigeration and air conditioning system how to safely isolate the system as well as how to purge air from it? You will also learn about the management of oil return; the functions working principles and components of a single compressor system; and all about multi-compressor systems. The process of oil return in the suction collector and to the crankcases centralized oil return as well as the efficiency of the oil separator using one separator per compressor will also be covered in this course. You will master high-pressure oil return as well as the proper processes required when adding oil to the system. You will also learn about the steps involved in cleaning the oil strainer as well as the key functions of oil in a refrigeration system and the classification of lubricating substances like natural mineral oil synthetic oil and half-synthetic oil. The detrimental effects of oil in a system once it gets past the compressor as well as how oil contamination in the refrigerating system reduces its overall efficiency will also be covered by the material.Furthermore this course will help you get familiar with preventive treatment and methods to avoid the introduction of moisture into the system. The harmful effects of oil in a system which include mechanical breakdown modification of thermodynamic properties of the refrigerant as well as decrease in the efficiency of exchangers will also be covered. Learn how to test compressor suction as well as the functioning of discharge valves. Study the definition of and reasons for defrosting as well as defrosting systems like water wash hot gas electric manual shutdown and warm brine defrosting. The various methods to defrost brine systems cargo fridge defrosting as well as methods of defrosting will also be demonstrated to you.
