Evaporator Coil

Evaporator coils are a crucial component in refrigeration and air conditioning systems, responsible for: 1. Heat absorption:  Absorbing heat from the surrounding air or fluid. 2. Evaporation:   Cooling the refrigerant liquid, causing it to evaporate into a gas. Types of evaporator coils: 1. Direct expansion (DX) coils:  Refrigerant flows directly through the coils. 2. Chilled water coils:  Chilled water flows through the coils to absorb heat. 3. Plate heat exchanger coils:  Use plates to transfer heat. Key characteristics: 1. Material:   Typically made of copper, aluminum, or steel. 2. Design:  Coils can be circular, oval, or rectangular. 3. Size:  Varies depending on the system's cooling capacity. 4. Fins:   Added to increase surface area for heat transfer. Factors affecting evaporator coil performance: 1. Temperature:   Ambient temperature and refrigerant temperature. 2. Airflow:  Adequate airflow is crucial for heat transfer. 3. ...
