The study results showed : ( 1 ) the bigger the temperature difference between indoor and outdoor air , the more obvious and more flux of the drop flow ; ( 2 ) the drop flow influenced the room temperature distribution and could even destroy the indoor temperature delamination ; ( 3 ) the prediction values agreed well with the test values , and the modified model could be utilized completely to predict the air - temperature distribution in a chilled wall room with underfloor system 研究表明室内外温差越大，壁面下降流越显著且流量越大；下降流影响房间内温度分布且破坏了地板送风房间的温度分层特性；预测值与实验值有着良好的一致性，因此该模型可用来预测具有冷却壁面的地板送风房间温度分布。
It does not need much area , not any pollution , not consuming much electricity power , not need much cost . gshp combined floor radiation air - conditioning system possess high seasonal average cop value and great capacity of edaphic depositing heat energy , can ease up supplied water temperature fluctuating with the change of the outdoor air temperature 地源热泵技术联合地板辐射对房间进行冷暖联供的形式,具有地源热泵季节性平均性能系数高、土壤蓄热能力强、能缓解空气源热泵存在的供冷供热能力随环境温度波动大的矛盾等优点。
The evaporation section and the condensation section of the heat pipes can ben changed as the temperature of the outdoor air varies . so the heat pipe can be operated through the whole year . after analyzing the characteristics of energy recovery in air - conditioning system , associating heat feature of air - conditioning system with running environment 分析了空调系统排风能量回收的特点后,作者结合空调系统运行环境,建立了该传热装置的数学模型,结果表明:热虹吸管的倾斜角、充液率、管长和迎面风速对热虹吸管的传热都有重要影响。
So this paper try to study fresh air and indoor air quality problem with uncertain method . this paper firstly utilizes grey systematic theory and already existing definite physical model to develop the non - intrinsic grey model of the effect of outdoor air on indoor air and analyse every grey parameter in the non - intrinsic grey model . on the basis of above mentioned , the change of carbon dioxide concentration indoor with the change of time is evaluated 根据灰色系统理论的建模思想，利用灰色系统理论和原有的确定性物理模型建立新风量对室内空气品质影响的灰色非本征模型，并对灰色非本征模型中的各个灰参数进行分析，在此基础上，将建立的模型对不同新风量条件下室内co _ 2浓度随时间的变化过程进行模拟计算分析。
The results show that the indoor air is unpolluted and the main contamination is particulates with diameter of 10 m or less , total volatile organic compounds and ozone ; the pollution mostly comes from personnel , merchandise and outdoor air ; the unacceptability ratio of the indoor air quality is 22 . 64 % , so the indoor air is unacceptable ; indoor persons have caught sick building syndrome ( sbs ) ; long time and low concentration pollution is an important characteristic of indoor pollution ; and the satisfied degree of indoor persons on the temperature , relative humidify , illumination and vision is very high 结果表明，商场室内处于未污染状况，主要污染物是可吸入颗粒物、总挥发性有机化合物和臭氧；主要污染来源于顾客、商品和室外空气；商场内人员对室内空气的不可接受率为22 . 64 % ，室内空气属于不可接受；室内人员已有病态建筑综合症发生；长时间低浓度污染，是室内污染的重要特征；室内人员对商场的温度、相对湿度和室内光照度、视觉环境等满意程度很高。
This paper analyzes the impacts in energy consumption and indoor environment parameters by different hvac indoor air temperature control strategies , humidity control strategies and outdoor air control strategies equipped with in hvac systems , and presents some means and measures to achieve energy saving and obtain disable indoor air environment in terms of these control strategies and operating management 本文对所确立的研究对象从空调系统的室内温度、湿度和新风控制策略出发多方位、多角度地研究了它们对空调系统运行能耗和室内环境参数的影响，并从控制策略和设计、运行管理上提出了实现空调系统节能运行同时兼顾室内环境参数的办法和措施。
Generally speaking , studies concerning about the energy , saving for hvac systems are carried out passively or initiatively , this paper intend to discuss the impacts produced by different hvac indoor air temperature control strategies , humidity control strategies and outdoor air control strategies in different hvac systems in terms of energy consumption and indoor environment parameters 一般而言，研究空调系统的节能主要是从两个方面进行：被动方面和主动方面。本文是从后者出发探讨空调系统中的室内温度、湿度和新风控制策略对空调系统运行能耗的影响，同时也涉及到不同的控制策略对室内环境参数的影响分析。
