"A real data set collected from an experimental set-up of a HVAC system in an industrial data center designed to simulate refrigerant leakage is used to validate and evaluate the proposed method (byLLC \u201dDATARK\u201d).The experimental testbed consists of a closed direct-expansion (DX) cooling circuit operating on R410A refrigerant [39], it includes several key components: compressor, air condenser, evaporator, re-ceiver, filter-dryer, HGBP control valve and forced ventilation system. Although our experimental testbed uses a single DX cooling circuit, it captures the core thermodynamic fault mechanisms that scale to production-scale redundant topologies, providing a physically representative basis for evaluating topology-aware anomaly detection.Data was recorded at a rate of 1 measurement per minute. All signals are synchronized and contain no gaps, ensuring high data integrity for training deep learning models. The dataset comprises 12 sensor time series (from S1 to S12), each representing a physicalparameter of the refrigeration circuit and air distribution system. Each variable is a continuous signal recorded from the industrial sensors of the test setup. A brief description of each variable, ordered according to the physical flow from evaporator inlet to filter outlet, is given below:\u2022 S1: Air temperature at the air conditioner inlet is the temperature of the air entering the unit at the evaporator inlet.\u2022 S2: Average evaporator fan speed is the average operating speed of the fans at the evaporator.\u2022 S3: Air temperature at the air conditioner outlet is the temperature of the air leaving the unit after passing through the evaporator.\u2022 S4: Suction pressure is the refrigerant pressure on the suctionside of the compressor.\u2022 S5: Suction line temperature is the temperature of the refrig-erant vapor in the suction line.\u2022 S6: Compressor temperature is the temperature of the com-pressor housing.\u2022 S7: Discharge pressure is the refrigerant pressure on the discharge side of the compressor.\u2022 S8: Discharge line temperature is the temperature of the refrigerant in the discharge line.\u2022 S9: Freon temperature after the receiver is the temperature of the refrigerant immediately after the receiver.\u2022 S10: Freon temperature at the filter inlet is the temperature of the refrigerant on the inlet side of the filter-drier.\u2022 S11: Freon temperature at the filter outlet is the temperature of the refrigerant on the outlet side of the filter-drier.\u2022 S12: HGBP valve position is the relative position (opening) of the hot gas bypass valve."
