In terms of energy conservation and environmental protection, the chiller units utilize eco-friendly refrigerants-such as R410A-and incorporate variable-frequency drive technology. This allows the compressor speed to adjust automatically in response to actual load conditions, achieving energy savings of over 30% compared to traditional models. The evaporator features a high-efficiency titanium-tube heat exchange design, offering exceptional corrosion resistance and making it particularly well-suited for circulating corrosive cooling media within the chemical industry. An integrated electronic expansion valve dynamically regulates refrigerant flow in real-time based on load fluctuations, thereby preventing energy waste.
The safety protection system incorporates multiple layers of safeguards: high- and low-pressure switches prevent issues arising from abnormal refrigerant pressures; a water flow switch ensures the proper circulation of cooling water; a phase sequence protector prevents motor reversal; and a compressor overload protection device is capable of immediately cutting off power in the event of an overload. For specialized industrial requirements, explosion-proof unit configurations are available as an option, fully compliant with ATEX certification standards.
Energy Efficiency and Conservation Requirements
Water-cooled chillers must comply with the mandatory national energy efficiency standard, GB 19577-2024: *Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Heat Pumps and Chillers*. This standard establishes minimum thresholds for the Coefficient of Performance (COP) and the Integrated Part Load Value (IPLV) for various types of chiller units.
High-efficiency operation leads to a significant reduction in electricity consumption, thereby lowering carbon emissions at the power generation source. For instance, magnetic-bearing variable-frequency centrifugal water-cooled chillers-through their oil-free operation and variable-frequency modulation capabilities-achieve an overall energy efficiency improvement of 30% to 40% compared to conventional chiller models.
