【摘要】：隨著人們生活水平的提高和滑冰運(yùn)動(dòng)的興起,室內(nèi)人工冰場(chǎng)的建設(shè)迎來了新的發(fā)展機(jī)遇。無論是發(fā)達(dá)國家還是發(fā)展中國家,人工冰場(chǎng)與其它公共建筑最大的不同在于制冷系統(tǒng)運(yùn)行的同時(shí),需要制熱系統(tǒng)、通風(fēng)系統(tǒng)和除濕系統(tǒng)等共同運(yùn)行,其作為最消耗能量的公共建筑之一,合理的設(shè)計(jì)系統(tǒng)和節(jié)能性研究是十分重要的。室內(nèi)空氣濕度過大時(shí)容易造成金屬腐蝕、木質(zhì)結(jié)構(gòu)腐朽,嚴(yán)重時(shí)可破壞建筑物結(jié)構(gòu),還會(huì)造成冰面起霧,使滑冰者視線模糊、行動(dòng)困難;同時(shí)濕潤的空氣更容易滋生細(xì)菌和有害物質(zhì),影響室內(nèi)空氣品質(zhì)和人員舒適性。因此,本文研究的主要目的是根據(jù)除濕系統(tǒng)的設(shè)計(jì)要求設(shè)計(jì)合理的氣流組織形式,同時(shí)分析不同除濕系統(tǒng)在不同干濕度氣候區(qū)的節(jié)能效率。主要研究內(nèi)容包括人工冰場(chǎng)新風(fēng)除濕系統(tǒng)的設(shè)計(jì)要求、人工冰場(chǎng)氣流組織的模擬和不同除濕系統(tǒng)的節(jié)能性分析。首先,新風(fēng)除濕系統(tǒng)的設(shè)計(jì)要求主要針對(duì)室內(nèi)溫濕度設(shè)計(jì)參數(shù)、潔凈度和最小新風(fēng)量等,確保冰場(chǎng)避免起霧和結(jié)露,并利用焓濕圖分析了起霧的原因。其次,利用Fluent軟件對(duì)不同氣流組織形式下室內(nèi)溫濕度分布進(jìn)行模擬,發(fā)現(xiàn):采用上送下回、送回風(fēng)口雙側(cè)布置的氣流組織形式時(shí),室內(nèi)豎直方向上溫度出現(xiàn)了合理的分層,隨著豎直高度增加,空氣溫度也在不斷增加,在水平方向上,室內(nèi)空氣溫濕度分布均勻;而送回風(fēng)口單側(cè)布置的氣流組織形式下,室內(nèi)空氣分布不均勻,在靠近風(fēng)口處空氣會(huì)發(fā)生起霧現(xiàn)象;室內(nèi)空氣的溫度隨著送風(fēng)溫度的升高而升高、相對(duì)濕度隨送風(fēng)溫度的升高而降低,因此送風(fēng)溫度越高,冰場(chǎng)起霧的可能性越低。設(shè)計(jì)了三種節(jié)能性除濕系統(tǒng),分別為帶余熱回收的冷卻除濕系統(tǒng)、帶熱回收的轉(zhuǎn)輪除濕系統(tǒng)以及低溫再生熱泵轉(zhuǎn)輪除濕系統(tǒng)。最后,結(jié)合不同除濕系統(tǒng)的運(yùn)行特點(diǎn)和不同干濕氣候區(qū)四個(gè)典型城市的室外氣象參數(shù),對(duì)三種除濕系統(tǒng)的節(jié)能性進(jìn)行探討,得出低溫再生熱泵轉(zhuǎn)輪除濕系統(tǒng)是代表濕潤地區(qū)的杭州、半濕潤地區(qū)的西安以及半干旱地區(qū)的蘭州的最佳除濕系統(tǒng),并且室外空氣濕度越大,節(jié)能性越高,相比于帶余熱回收的冷卻除濕系統(tǒng)具有60%左右的節(jié)能性;在干旱地區(qū)的烏魯木齊最佳除濕系統(tǒng)為帶熱回收的轉(zhuǎn)輪除濕系統(tǒng),節(jié)能率為48.5%。通過本文的研究,為娛樂型室內(nèi)人工冰場(chǎng)新風(fēng)除濕系統(tǒng)的設(shè)計(jì)提供了合理的解決思路,并為降低節(jié)能運(yùn)行成本提供參考。
[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.
