What are the advantages and disadvantages of liquid chiller?

1. The refrigerant charge is small, which is conducive to environmental protection and reducing operating costs

The volume of shell side and tube side of FL +5°C ~ +35°C Water Chillers is large. To make the refrigeration system work normally, a large amount of refrigerant must be filled, and it may also cause environmental pollution. On the one hand, the cooler is small, on the other hand, the spacing size is also small.

2. Low freezing tendency and high frost resistance

As water can form high turbulence in the cooler at low flow rate, the temperature distribution is very uniform, thus reducing the freezing tendency of chilled water. Even if freezing occurs, it can withstand the pressure generated by freezing, and unlike the shell-and-tube heat exchanger, it is easy to expand and crack the heat pipe, and can continue to use after freezing.

3. Thorough evaporation and high economy

When the refrigerant evaporates in the refrigeration cooler, it is easy to achieve complete evaporation to a liquid-free level.

Therefore, in most cases, the refrigeration system does not need to be equipped with a gas-liquid separator. Besides, it is easy to realize unit, easy to install, and can save costs and reduce costs in maintenance and transportation.

Disadvantages of water cooler: the condensation effect is greatly affected by water quality.

When the water quality is poor, the water pressure is insufficient, and the water flow rate is less than 1m/h, scaling is fast, and the heat transfer rate drops sharply.

Therefore, it often occurs that the vacuum degree at the top of the tower is high at the beginning of operation after the maintenance of the unit, and then gradually decreases with the passage of time.
