Method and apparatus for cooling system

Abstract

The present system provides an improved architecture for cooling server cabinets as well as adapting operations based on dynamic energy costs. The system utilizes a small oil-free compressor, which is distributed on the top of the cabinet, reducing the distance from the evaporator outlet to the compressor suction port, and combines phase change energy storage material and free cooling control technology to achieve further energy-saving effects. The technical scheme adopted by the invention to solve the technical problem is an oil-free direct-expansion cooled communication cabinet, characterized in that it is comprised of an oil-free compressor, with at least one condenser and one evaporator, a throttling device, a gas-liquid separation device, and a communication cabinet. The system stores cold capacity when energy costs are low and releases stored cold capacity when energy costs are high.
