【摘要】：随着人们生活水平的提高和滑冰运动的兴起,室内人工冰场的建设迎来了新的发展机遇。无论是发达国家还是发展中国家,人工冰场与其它公共建筑最大的不同在于制冷系统运行的同时,需要制热系统、通风系统和除湿系统等共同运行,其作为最消耗能量的公共建筑之一,合理的设计系统和节能性研究是十分重要的。室内空气湿度过大时容易造成金属腐蚀、木质结构腐朽,严重时可破坏建筑物结构,还会造成冰面起雾,使滑冰者视线模糊、行动困难;同时湿润的空气更容易滋生细菌和有害物质,影响室内空气品质和人员舒适性。因此,本文研究的主要目的是根据除湿系统的设计要求设计合理的气流组织形式,同时分析不同除湿系统在不同干湿度气候区的节能效率。主要研究内容包括人工冰场新风除湿系统的设计要求、人工冰场气流组织的模拟和不同除湿系统的节能性分析。首先,新风除湿系统的设计要求主要针对室内温湿度设计参数、洁净度和最小新风量等,确保冰场避免起雾和结露,并利用焓湿图分析了起雾的原因。其次,利用Fluent软件对不同气流组织形式下室内温湿度分布进行模拟,发现:采用上送下回、送回风口双侧布置的气流组织形式时,室内竖直方向上温度出现了合理的分层,随着竖直高度增加,空气温度也在不断增加,在水平方向上,室内空气温湿度分布均匀;而送回风口单侧布置的气流组织形式下,室内空气分布不均匀,在靠近风口处空气会发生起雾现象;室内空气的温度随着送风温度的升高而升高、相对湿度随送风温度的升高而降低,因此送风温度越高,冰场起雾的可能性越低。设计了三种节能性除湿系统,分别为带余热回收的冷却除湿系统、带热回收的转轮除湿系统以及低温再生热泵转轮除湿系统。最后,结合不同除湿系统的运行特点和不同干湿气候区四个典型城市的室外气象参数,对三种除湿系统的节能性进行探讨,得出低温再生热泵转轮除湿系统是代表湿润地区的杭州、半湿润地区的西安以及半干旱地区的兰州的最佳除湿系统,并且室外空气湿度越大,节能性越高,相比于带余热回收的冷却除湿系统具有60%左右的节能性;在干旱地区的乌鲁木齐最佳除湿系统为带热回收的转轮除湿系统,节能率为48.5%。通过本文的研究,为娱乐型室内人工冰场新风除湿系统的设计提供了合理的解决思路,并为降低节能运行成本提供参考。
[Abstract]:With the improvement of people's living standard and the rise of skating, the construction of indoor artificial ice rink has ushered in a new development opportunity. Whether in developed or developing countries, the biggest difference between artificial ice rink and other public buildings lies in the operation of refrigeration systems, which require the joint operation of heating systems, ventilation systems and dehumidification systems. As one of the most energy-consuming public buildings, reasonable design system and energy saving research are very important. When the indoor air humidity is too large, it is easy to cause metal corrosion, wood structure decay, serious damage to the building structure, but also cause ice fog, so that the sight of the skaters blurred, difficult to move; At the same time, moist air is more likely to breed bacteria and harmful substances, affecting indoor air quality and personnel comfort. Therefore, the main purpose of this study is to design a reasonable airflow organization form according to the design requirements of the dehumidification system, and to analyze the energy saving efficiency of different dehumidification systems in different dry and wet climate regions. The main research contents include the design requirements of fresh air dehumidification system in artificial ice rink, the simulation of air flow organization in artificial ice rink and the analysis of energy saving of different dehumidification systems. First of all, the design requirements of fresh air dehumidification system are mainly aimed at indoor temperature and humidity design parameters, cleanliness and minimum fresh air volume to ensure that ice rink avoid fog and dew, and use enthalpy and humidity diagram to analyze the causes of fog. Secondly, using fluent software to simulate the indoor temperature and humidity distribution in different airflow organization forms, it is found that when the air distribution forms arranged on both sides of the air outlet are adopted, the temperature in the vertical direction of the room appears reasonable stratification. With the increase of vertical height, the air temperature is also increasing, and in the horizontal direction, the indoor air temperature and humidity distribution is uniform, while the distribution of indoor air is uneven in the form of air distribution arranged on one side of the return tuyere. The temperature of indoor air increases with the increase of air supply temperature, and the relative humidity decreases with the increase of air supply temperature, so the higher the air temperature, the lower the possibility of fog in ice rink. Three kinds of energy saving dehumidification systems are designed, which are cooling dehumidification system with waste heat recovery, rotary dehumidification system with heat recovery and low temperature regenerative heat pump runner dehumidification system. Finally, according to the operation characteristics of different dehumidification systems and the outdoor meteorological parameters of four typical cities in different dry and wet climate regions, the energy saving properties of the three dehumidification systems are discussed. It is concluded that the dehumidification system of low temperature regenerative heat pump wheel is the best dehumidification system in Hangzhou, Xi'an and Lanzhou, which represents the humid area, and the higher the air humidity is, the higher the energy saving is. Compared with the cooling dehumidification system with waste heat recovery, the best dehumidification system in Urumqi is the rotary dehumidification system with heat recovery, and the energy saving rate is 48.5%. The research in this paper provides a reasonable solution for the design of the fresh air dehumidification system in the recreation indoor artificial ice rink and provides a reference for reducing the operation cost of energy saving.
