Water-cooled screw liquid full type water chiller

This invention relates to the field of refrigeration equipment technology, specifically to a water-cooled screw-type flooded chiller, comprising a chiller body and an evaporator. The evaporator is mounted on the chiller body, with an inlet pipe at its bottom and an outlet pipe at its top connected to a screw compressor on the chiller body. This invention uses a float plate and guide assembly to vertically raise and lower the tube bundle according to the refrigerant level: when the system load decreases and the liquid level drops, the tube bundle moves downwards synchronously, always remaining submerged in liquid refrigerant, avoiding the loss of heat exchange capacity due to the upper part of the traditional fixed tube bundle being exposed to gaseous refrigerant; when the load increases and the liquid level rises, the tube bundle moves upwards synchronously to a shallow liquid level area near the liquid surface, where the static pressure is lower, effectively overcoming the defect of traditional fixed tube bundles at the bottom where excessive static pressure inhibits refrigerant boiling. This ensures that the tube bundle is in the optimal heat exchange position under different loads, thereby significantly improving the overall heat exchange efficiency and the chiller's comprehensive energy efficiency ratio.
