| According to the characteristics of the passenger depot project,this subject do some jobs as follows by consulting design specifications of air-conditioning and hot-water,and using the heat transfer and mass transfer theory.(1)This setup mainly consists of get the parameters of dry bulb temperature and relative humidity by testing the air data which could be the main influence to the performance of direct evaporative cooling.the inlet air dry bulb temperature,inlet relative humidity,inlet wind speed and inlet water temperature of the direct evaporative cooling equipment to be test,then get the outlet data.Then get the different of the outlet air evaporative efficiency and humidifying volume in different situation.(2)According to the experiment data and the building structure of the bus station,the energy saving with high efficiency air-conditioning and hot-water system was designed by using the technology of direct evaporation cooling coupled ground source heat pump cooling and dehumidification.(3)After the project is done,observing the different indoor air dry bulb and relative humidity in the different situations which are direct evaporation or not,contrasting of these two condition the direct evaporative cooling system which coupled ground source heat-pump cooling and dehumidification.By the test above would give the bus station a operable advice about the air-condition operation that open the different cold source in the different passenger flow and surrounding.we found that our air conditioner system is more economic than the traditional air-conditioning.It not only can save the 48%initial investment but also save the about 81%operation cost each year. |
