👉 The comm fluid, also known as carbon monoxide (CO) fluid, is a specialized refrigerant used in vapor-compression refrigeration systems, particularly in air conditioning and heat pump applications. It is a colorless, odorless, and highly toxic gas that acts as a refrigerant by absorbing heat from the environment and releasing it elsewhere, thus facilitating cooling. The fluid is designed to be non-flammable and chemically stable, making it safer than traditional refrigerants like chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). When a compressor circulates the CO fluid through the system, it undergoes phase changes from liquid to vapor and back to liquid, enabling efficient heat transfer. Proper handling and maintenance are crucial due to its toxicity, and systems often include safety valves and leak detection mechanisms to prevent accidents.
