Air-Cooled Copeland Screw Chiller BSL Series (Single Compressor) 7-25℃ Working Temp High-Accuracy Temperature Control

1. Temperature Control Range: Supports adjustment of chilled water outlet temperature between 7-25℃ (actual parameters are subject to specific models), meeting the medium-to-low temperature requirements of most industrial processes.
2. Control Precision: Achieves a temperature stability of ±0.5℃ through the PLC+HMI intelligent control system (specific precision varies by model). It enables real-time monitoring and adjustment of compressor energy output, as well as dynamic tracking of load changes.
3. Intelligent Algorithm: Integrates PID (Proportional-Integral-Derivative) adjustment logic. Combined with high-frequency sampling (10k/s) from temperature sensors, it responds quickly to temperature fluctuations and prevents overshoot or undershoot.

High-Efficiency Heat Exchange System

Evaporator & Condenser: Adopt a finned design, paired with copper tubes manufactured using oxygen-free welding technology. This structure increases heat transfer efficiency by over 30% while reducing energy consumption.

Refrigerant Compatibility: Supports multiple environmentally friendly refrigerants such as R22, R407C, and R134a. Customization is available based on customer requirements.

Key Notes on Technical Terminology:

PLC+HMI: Abbreviation for "Programmable Logic Controller + Human-Machine Interface", a standard industrial control configuration, so the acronym is retained for clarity.

PID: Full name "Proportional-Integral-Derivative", a widely used automatic control algorithm; the acronym is commonly used in international technical documents.

Refrigerant Codes (R22/R407C/R134a): Industry-unified designations for refrigerants, which are consistent across global technical standards and do not require additional translation.
