Components that collect and distribute refrigerant flow within condenser coils

Product Specifications

Technical details and manufacturing context for Headers/Distributors

Definition
Headers and distributors are critical components in condenser coils that manage refrigerant flow by collecting refrigerant from multiple tubes and distributing it evenly across the coil's circuiting system, ensuring optimal heat transfer efficiency and pressure balance throughout the heat exchange process.
Working Principle
Headers receive refrigerant from the compressor and distribute it to multiple parallel tubes in the condenser coil. Distributors ensure even flow distribution to prevent uneven cooling and maintain system efficiency. They work by creating pressure differentials that force refrigerant through multiple pathways while maintaining balanced flow rates.
