The TICA Water-Cooled Flooded Screw Chiller (Heat Pump) – TWSF Series is engineered to provide dependable, energy-efficient chilled water and heating solutions for large commercial, institutional, and industrial facilities. It combines a high-efficiency semi-hermetic double-screw compressor, flooded evaporator, premium shell-and-tube heat exchangers, and an intelligent microcomputer control system.
The TWSF Series is available in three targeted configurations to meet specific project and energy source requirements:
Cooling-Only Chiller (FC Series): Provides efficient chilled water for central air-conditioning and industrial process cooling.
Water Source Heat Pump (FW Series): Uses underground water, surface water, seawater, or treated wastewater as renewable energy sources to provide cooling during summer and heating during winter.
Geothermal Heat Pump (FG Series): Utilizes stable ground temperatures for year-round heating and cooling, eliminating the need for conventional cooling towers and significantly lowering operating costs.
Precision Control: Features a German-patented semi-hermetic double-screw compressor with high adiabatic efficiency and stepless capacity control.
Load Matching: Automatically adjusts cooling capacity from partial load to full load, ensuring precise temperature control while minimizing electrical consumption.
Enhanced Reliability: Incorporates a high-efficiency three-stage oil separator and a patented oil return system to maintain optimal lubrication under all operating conditions.
Flooded Evaporator & Condenser: Designed with enhanced copper heat transfer tubes and Computational Fluid Dynamics (CFD)-optimized internal flow paths to maximize heat exchange.
Dynamic Response: Paired with an Electronic Expansion Valve (EXV) to respond quickly to changing load conditions, keeping operations stable.
High COP: Many models achieve Coefficient of Performance (COP) values exceeding 6.0 in cooling mode.
Eco-Friendly: Utilizes environmentally responsible R134a refrigerant.
The series features an industrial-grade microprocessor controller paired with a 7-inch color touchscreen interface.
Smart Optimization: Intelligent control algorithms continuously optimize compressor performance, water temperature, and system operation based on actual building demand.
System Diagnostics: Offers predictive diagnostics, automatic fault detection, weekly scheduling, and multi-compressor load balancing.
Seamless Integration: Includes standard RS485 Modbus RTU communication for Building Automation System (BAS) central monitoring and remote control. Optional wireless communication is available for remote monitoring and alarm notifications.
Streamlined Setup: Units are factory charged with refrigerant, insulated, vibration-isolated, and supplied with flanged water connections to simplify on-site piping.
Space-Saving Design: Features a compact footprint ideal for mechanical rooms where space is limited.
Variable Primary Flow: Supports variable water flow capability (40% to 110% of nominal flow), making it highly compatible with modern variable-primary-flow systems.
