游泳馆暖通空调系统设计研究OA

Taking a certain swimming pool in Jinan City as the research object,the selection principles of indoor air conditioning design parameters is analyzed,the calculation methods of the dehumidification capacity and the supply air volume of the dehumidification heat pump unit are introduced,the working principle of the dehumidification heat pump and the anti-condensation measures are elaborated,and the two air conditioning system schemes are compared.The results show that when the indoor design parameters are indoor water temperature of 26.5℃,indoor air temperature of 28.0℃,and relative humidity of 65%,the total dehumidification capacity is 268.69 kg/h.Two dehumidification heat pump units with a supply air volume of 40 000 m3/h each are selected.Compared with the conventional scheme,the annual operating cost of the dehumidification heat pump scheme is reduced by 174 000 yuan,and the investment recovery period is approximately 3.4 a.The'three-in-one'dehumidification heat pump unit with reasonable selection can simultaneously achieve dehumidification,pool water heating,and air conditioning ventilation,and has a large potential for energy-saving.
