Расширительный клапан системы кондиционирования воздуха Caterpillar 432-2923

An Air Conditioner Expansion Valve controls the amount of refrigerant entering the evaporator. Positioned between the condenser and evaporator, it ensures that the refrigerant undergoes a pressure drop, transitioning from a high-pressure liquid to a low-pressure liquid-vapor mixture. This phase change allows the refrigerant to absorb heat efficiently from the surrounding air, enabling effective cooling. The expansion valve continuously adjusts the refrigerant flow based on cooling demand, preventing excessive or insufficient refrigerant supply.Attributes:• Reduces the risk of compressor overload by controlling refrigerant flow.• Maintains optimal pressure and temperature for efficient cooling.• Prevents freezing or flooding of the evaporator coil for improved system longevity.Applications: An Air Conditioner Expansion Valve is located between the condenser and the evaporator in the air conditioning system to control refrigerant flow and ensure efficient cooling operation.
