The TICA Air-Cooled Flooded Screw Chiller (TASF Series) is a premium air-cooled chilled water system designed to deliver reliable, energy-efficient cooling for medium to large commercial and industrial facilities. Utilizing advanced semi-hermetic twin-screw compressors specifically designed for R134a refrigerant, the chiller provides stepless capacity regulation that continuously adjusts cooling output according to system demand, reducing compressor cycling and maintaining stable chilled water temperatures.
The series is engineered with a flexible compression architecture to ensure optimal part-load efficiency and operational redundancy:
Single-Compressor Models: Provide stepless capacity modulation from 25% to 100% to match precise building loads.
Dual-Compressor Models: Provide an ultra-wide operating range from 12.5% to 100% for superior energy savings and built-in system redundancy.
Eco-Friendly R134a Refrigerant: Optimized specifically for R134a to deliver excellent thermal characteristics with lower environmental impact.
Flooded Shell-and-Tube Design: Features internally and externally enhanced heat transfer tubes. Fully surrounding the tubes with refrigerant maximizes heat absorption and reduces compressor workloads.
Integrated Economizer Cycle: Boosts overall cooling capacity and operating efficiency during peak demand.
Precision Electronic Expansion Valve (EEV): Continuously regulates refrigerant flow for exceptional system stability under both full- and part-load conditions.
99.9% Separation Efficiency: Utilizes a patented two-stage high-efficiency oil separator and continuous oil return technology to achieve separation exceeding 99.9%.
Minimal Carryover: Reduces oil carryover into the heat exchanger to ensure consistent compressor lubrication without decreasing thermal performance or increasing energy draw.
Sub-Degree Accuracy: Features an industrial-grade microprocessor with an LCD interface, providing chilled water temperature regulation with an accuracy of approximately ±0.3°C.
Smart Scheduling & Diagnostics: Includes weekly scheduling, automatic start/stop functions, fan staging control, and proactive fault diagnostics to minimize maintenance downtime.
Heavy-Duty Safeguards: Comprehensive protections cover compressor overload, high/low pressure, discharge temperature, oil levels, phase sequence, fan overload, and water temperature.
Supporting cooling capacities from 336 kW to 1,682 kW, this system is highly customizable with options like glycol compatibility (for low-temperature process loops), anti-corrosion coil coatings, and low-ambient operation down to -10°C:
