Tube Bundle for ERACO Chiller

Tube Bundle for ERACO Chiller

A tube bundle for a chiller is a key component used in the heat exchange process within the chiller unit. Chillers are refrigeration systems that remove heat from a liquid via a vapor-compression or absorption refrigeration cycle. The chilled liquid is then circulated through heat exchangers to cool air or equipment.

Here's how the tube bundle functions within a chiller:

Heat Exchange: The tube bundle is the part of the chiller where heat exchange occurs. It typically consists of a series of tubes arranged in a bundle configuration. The chilled liquid (often water or a water-glycol mixture) flows through these tubes.

Refrigerant Flow: Within the chiller, a refrigerant circulates through another set of tubes or passages adjacent to the tubes containing the chilled liquid. The refrigerant absorbs heat from the liquid in the tubes, causing it to evaporate and become a low-pressure vapor.

Heat Absorption: As the refrigerant absorbs heat from the chilled liquid, it undergoes a phase change from liquid to vapor. This process effectively removes heat from the liquid, cooling it down.

Efficient Cooling: The tube bundle design is optimized for efficient heat transfer between the refrigerant and the chilled liquid. Factors such as tube material, size, and arrangement contribute to maximizing heat exchange efficiency.

Condensation: After absorbing heat from the chilled liquid, the refrigerant vapor is compressed and condensed back into a liquid state in another part of the chiller. This releases the heat absorbed from the chilled liquid into the surroundings or a separate heat rejection system.

Repeat Cycle: The cycle repeats continuously, with the refrigerant circulating through the chiller's components, including the tube bundle, to maintain the desired temperature of the chilled liquid.

Tube bundles for chillers are often constructed from materials such as copper, aluminum, or stainless steel, chosen for their thermal conductivity, corrosion resistance, and compatibility with the working fluids used in the chiller system. The design and size of the tube bundle depend on factors such as the cooling capacity of the chiller, the desired temperature range of the chilled liquid, and the specific application requirements.
