Full liquid chiller

Full liquid chiller is a common refrigeration equipment, with the following main characteristics:

Efficient and energy-saving:

The design of a full liquid evaporator allows the refrigerant to evaporate fully inside the evaporator, enabling sufficient heat exchange with the refrigerant (usually water). The refrigerant liquid completely submerges the heat transfer tube, increasing the heat transfer area, and the refrigerant evaporates outside the tube, resulting in a higher heat transfer coefficient and higher refrigeration efficiency. Compared with other types of chillers, it can effectively reduce energy consumption and save operating costs.

High cooling capacity:

Full liquid chillers typically use large-diameter evaporators and efficient compressors, which can handle large refrigeration demands. Suitable for large commercial buildings, industrial plants, data centers, and other places that require a large amount of cooling capacity.

Stable operation:

The refrigerant level in the full liquid evaporator is stable, which can ensure the uniform distribution of refrigerant in the evaporator, avoid local overheating or undercooling caused by uneven refrigerant distribution, and thus improve the operational stability of the refrigeration system. In addition, the compressor of a full liquid chiller usually adopts a screw or centrifugal compressor, which has the advantages of smooth operation, low vibration, and low noise, further ensuring the stable operation of the entire system.

The refrigerant charging amount is relatively large:

Due to the need for the evaporator to be filled with refrigerant to achieve good heat transfer efficiency, the refrigerant charge of the full liquid chiller is relatively large. This requires good sealing of the system to prevent refrigerant leakage. When choosing a refrigerant, it is necessary to consider factors such as the properties and cost of the refrigerant.

High requirements for water quality:

The water flow velocity in the evaporator of a full liquid chiller is relatively low, which can easily cause impurities and minerals in the water to deposit on the surface of the heat transfer tube, forming scale and affecting the heat transfer effect. The water quality requirements for entering the chiller are high, and corresponding water treatment equipment is usually needed to reduce the formation of scale and ensure the normal operation of the chiller.

Large footprint:

The evaporator and condenser of a full liquid chiller usually adopt a shell and tube structure, which has a large volume and requires a large installation space. In order to ensure the normal operation and maintenance of the chiller, it is necessary to reserve a certain amount of operating space and maintenance channels, so the overall footprint is relatively large.
