Notes:

[1] Rated operating performance under standard conditions (15°C, 101.325 kPa, 60% relative humidity).

[2] Derived based on the lower heating value of natural gas at 34 MJ/Nm3 (where the standard conditions for Nm3 are 0°C and 325 kPa).

[3] Steam output is based on a steam pressure of 0.8 MPa(g) and a steam temperature of 175°C.

[4] Drying heat is based on flue gas heat at temperatures above 120°C.

[5] Hot water output is derived under the conditions of an inlet water temperature of 15°C, an outlet water temperature of 60°C, and a flue gas outlet temperature of 75°C.

[6] Cooling capacity is obtained based on an absorption chiller exhaust gas temperature of 160°C, with a simple cycle COP of LS and a heat recovery cycle COP of 1.0.

[7] Heating capacity is derived based on an absorption chiller exhaust gas temperature of 145°C and a COP of 0.93.

[8] Energy supply area is calculated based on a cooling load of 40~90 W/m2, which is for reference only. Due to variations in the load of different buildings, the actual energy supply area shall be determined according to the specific conditions of the building.

[9] The fuel supply pressure here refers to the pressure required for gas to be supplied directly to the gas turbine
(without a compressor) or supplied to the gas turbine after being compressed by a compressor.

[10] This refers to the flue gas volume flow rate under standard conditions (0°C, 101.325 kPa).
