flamability & Oxygen depleation
The two types of refrigeration systems are vapor compression systems and absorption systems. Vapor compression systems use a compressor to circulate refrigerant, while absorption systems use heat to drive the cooling process.
The two types of refrigeration are vapor compression refrigeration and absorption refrigeration. Vapor compression refrigeration is the most common type and is used in most household refrigerators and air conditioning systems. Absorption refrigeration, on the other hand, uses heat to generate a refrigerant vapor instead of a mechanical compressor.
R12 and R134a are two different types of chemicals used in vehicle refrigeration systems. If you mix the two together, you can corrode the system and cause major damage.
The main two refrigeration giants are Thermo King and Carrier
Two problems that a refrigeration system could have are compressor problems or a lack of or loss of refrigerant gas.
Classifications for occupational hazards include physical hazards, chemical hazards, and biological hazards. Psychosocial hazards and mechanical hazards are the other two classifications.

Mechanical engineers design, build, and maintain a variety of systems, primarily focusing on thermal systems and mechanical systems. Thermal systems include heating, ventilation, and air conditioning (HVAC) systems, as well as engines and refrigeration units. Mechanical systems encompass machinery, robotics, and manufacturing equipment. Both types of systems are crucial for industrial processes, energy efficiency, and overall functionality in various applications.
Cross bonding is a method used in electrical systems to connect two different grounding systems in order to ensure electrical continuity and safety. It is commonly used in situations where different parts of a facility or system have separate grounding systems to prevent electrical hazards.
