AI Technical Summary

Technical Problem

Existing horizontal chiller units occupy a large area, are inconvenient to transport and install, especially in space-constrained environments, and have complex piping connections.

Method used

The system employs a vertical cooling water system, which compactly arranges the condenser, electronic expansion valve, evaporator, and compressor. Multiple refrigerant lines are connected to form multiple refrigerant circuits. The evaporator is vertical, the condenser is horizontal and stacked one on top of the other, and the compressor is arranged horizontally side by side, simplifying the piping connection.

Benefits of technology

This significantly reduces the footprint of the chiller unit, facilitates transportation and installation, simplifies pipe connections, and lowers the difficulty of transportation and installation.
