EVAPORATOR UNITS
The evaporator is to receive low-pressure, low temperature fluid from the expansion valve and to bring it in close thermal contact with the load.
✓ The refrigerant takes up its latent heat from the load and leaves the Evaporator as a dry gas.
✓ The function of the evaporator will be to cool gas, liquid or other Product loads.
✓ In most cases air or a liquid is first cooled, and this is then used to Cool the load. e.g., in a cold-room air is cooled and this air cools the Stored produce and carries away heat leaking through the structure; In a water chiller, water is circulated to cool the load, etc.
TYPES OF EVAPORATOR UNITS
✓ Shell & Tube Evaporators
✓ Brazed Plate Type Evaporator
✓ Tube Coils / Tube Bundles Evaporator
✓ Falling Film Evaporator
✓ Flooded Evaporator
✓ Direct Expansion (DX) Evaporator
✓ Plate and Frame Evaporator
ADVANTAGES OF EVAPORATER UNITS
✓ Facilitate efficient heat exchange between the refrigerant or process fluid and the surrounding environment, ensuring effective cooling or heating.
✓ Used in a wide range of applications such as HVAC systems, industrial processes, refrigeration, and power generation, showcasing their adaptability across different industries.
✓ Many evaporator units, like brazed plate types, are compact in size, which is advantageous for installations where space is limited or needs to be optimized.
✓ Advanced designs and materials used in evaporator units help improve energy efficiency, leading to reduced operating costs and environmental impact.
