Shell and tube liquid coolers - flooded-type

Shell-and-tube liquid coolers filled type

They are usually used in large applications. Liquid cooled and passed through the tubes, the boiling of refrigerant in the boiling vapors from the chassis. Refrigerant level in the shell is maintained so that the upper tube always covered with liquid. Thus, the most effective heat exchange, liquid-liquid, is achieved throughout the cooling interface. On Fig. 9 is an example of this type of evaporator.

For optimal effectiveness, liquid level, as a rule, supported by a low pressure float valve. In addition, the expansion device and level sensor can be used. Space in the upper part of the body allows any droplets of liquid should be separated from the steam is returned to the compressor. This separation is sometimes achieved in another vessel, called the separator.
