Shanghai Pudong International Airport
Basic information of T3 satellite Hall of Pudong International Airport
The third phase of the expansion project includes satellite hall, MRT system and other facilities. Among them, the main project satellite hall has a total construction area of 622000 square meters, nearly 140000 square meters larger than Pudong airport T2 terminal building, which is the largest single satellite hall in the world at present. It is composed of two parts (S1 and S2). It is connected with the existing T1 and T2 terminals respectively through the MRT system, with a designed annual throughput of 38 million people. After completion in 2019, Pudong Airport has an annual passenger throughput capacity It will reach 80 million people.
Design parameter requirements
Design parameters of outdoor air conditioning:
Summer: dry bulb temperature 33.8 ℃, wet bulb temperature 28.3 ℃, ventilation temperature 31.5 ℃ and wind speed 2.0m/s in summer
Winter: air conditioning dry bulb temperature in winter 1.4 ℃, relative humidity 76%, winter ventilation temperature 8 ℃, wind speed 2.9m/s
Scheme description
The air conditioning system of T3 satellite Hall of Pudong Airport adopts 42 DHP heat pipes and 22 HRM heat recovery heat pipes in total. According to the requirements of Party A and the design, and in combination with the power condition and size of the supporting cold coil pipes, our company has designed the corresponding system, which can meet the requirements of many complex field environments for installation. Compared with other heat recovery energy-saving products, it has no cross infection, no energy consumption drive, low pressure drop and easy operation The advantages of maintenance and long service life are particularly significant. Two of the design parameters are shown as follows:
Energy saving analysis
1. Operating parameters
a、HRM
Air inlet condition | Air supply condition | Return air condition | Exhaust condition | |
Dry bulb (℃) | 34.4 | 27.49 | 24 | 30.69 |
Wet bulb (℃) | 27.9 | 26.27 | 18.6 | 20.7 |
relative humidity | 61.3% | 91% | 60% | 40.6% |
b、DHP
Air inlet condition | Conditions after DHP Precooling | Working condition of outlet cooler | DHP working condition after reheating | |
Dry bulb (℃) | 26.5 | 22.31 | 12.5 | 16.72 |
Wet bulb (℃) | 20.4 | 19.09 | 12.04 | 13.74 |
relative humidity | 57.75% | 74.22% | 94.99% | 72.32% |
2. Energy saving analysis and calculation
a. Calculation of unit energy consumption reduction
Energy saving of the surface cooler: according to the formula q = Cp * m * △ t = Cp * ρ * V * △ T, on the premise of constant temperature and humidity, the energy saving of the selected two prototype products is hrm14.4kw and dhp67.8kw
b. Operation cost saving calculation
Location: | Shanghai | ||
Air conditioning operation time: | DHP: 24h / day * 122d = 2928h (June September) | ||
HRM: Summer 12h / day * 122d = 1464h (June September) | |||
Winter 12h / day * 151 days = 1812h (November March) | |||
Heating coefficient: | 3.6 | Cooling coefficient: | 3.2 |
electricity fees: | 1.2 yuan / kW. H |
The annual operation cost saved is 92000 yuan. Combined with the initial investment, the recovery of the initial investment was completed in about one and a half years.
