The invention discloses a design method of an energy-saving integrated water chilling unit. Modularized design is adopted, a compression module, a condensation module, an expansion module, an
evaporation module and a control module are included, and all the modules can be flexibly combined; an
intelligent control system is arranged, a sensor is used for collecting data, the
operation mode is automatically adjusted through an intelligent
algorithm, and remote monitoring is supported. And high-efficiency
refrigeration technologies, such as a variable-frequency compressor, an optimized
heat exchanger and a condensation mode, selection of a low-GWP
refrigerant and the like, are applied. The
waste heat recovery and utilization device is arranged, environment-friendly refrigerants and energy-saving materials are adopted, fine management is achieved through an energy-saving optimization
algorithm and
data analysis, and meanwhile the structure is compact and the
automation degree is high. The unit is efficient, energy-saving, environment-friendly, intelligent and convenient, is suitable for multiple fields, and effectively improves the comprehensive performance and the use experience.
