关于“温湿度独立控制空调系统”的评述 总被引:1,自引:0,他引:1
如何营造既节能又舒适的室内环境,是人们一直关注的焦点。健康的室内环境要求热舒适性与空气品质俱佳。室内环境温度与湿度是影响人体热舒适感觉的2个重要环境因素。常规的热湿联合处理空调系统在这方面存在先天的缺陷,而温湿度独立控制空调系统通过对空调房间的温度与湿度分别独立控制,从而具有明显的优势。该系统主要由2个部分组成:处理潜热负荷系统与处理显热负荷系统;2个系统独立调节控制室内的湿度与温度。 相似文献

以采用一次回风集中空调系统的办公建筑为例,就室内温、湿度设计参数对空调房间热舒适环境和空调系统能耗的影响进行了分析。研究结果表明,在同样的室内人体热舒适环境(等效温度)的条件下,随着室内温度的增加,一次回风系统的需冷量和总的耗能量是增加的。因此,夏季提高空调室内温度是不节能的。在相同热舒适(等效温度)条件下,要减少空调系统的冷负荷,室内设计温、湿度参数在推荐的热舒适区范围内,宜采用较大的室内相对湿度和较低的室内干球温度的组合,或采用较高的等效温度。 相似文献

A study was carried out to investigate the effect of heat-pipe air-handling coil on energy consumption in a central air-conditioning system with return air. Taking an office building as an example, the study shows that compared with conventional central air-conditioning system with return air, the heat-pipe air-conditioning system can save cooling and reheating energy. In the usual range of 22–26 °C indoor design temperature and 50% relative humidity, the RES (rate of energy saving) in this office building investigated is 23.5–25.7% for cooling load and 38.1–40.9% for total energy consumption. The RES of the heat-pipe air-conditioning system increases with the increase of indoor design temperature and the decrease of indoor relative humidity. The influence of indoor relative humidity on RES is much greater than the influence of the indoor design temperature. The study indicates that a central air-conditioning system can significantly reduce its energy consumption and improve both the indoor thermal comfort and air quality when a heat-pipe air-handling coil is employed in the air-conditioning process. 相似文献

室内空气设计参数与空调系统节能条件浅析 总被引:1,自引:0,他引:1
本文针对暖通空调系统设计过程中室内空气参数标准的合理取值对空调能耗的影响,探讨了空调负荷、空调能耗和空调系统节能的基本概念,对室内空气温度和相对湿度标准对空调系统能耗的影响进行了计算分析,结果表明科学认识室内空气参数标准的合理取值对空调系统能耗的影响对当前建筑节能意义重大;空调系统节能条件需要具体分析,针对不同类型的建筑和不同的空调方式,其室内空气设计标准的影响不同,空调过程设计对空调系统节能具有重要影响。另外,将典型空调案例的计算结果推广到一般工程,容易导致工程设计概念上的混淆。 相似文献

A new method of determination of indoor temperature and relative humidity with consideration of human thermal comfort 总被引:1,自引:0,他引:1
A new method is described in this article for selecting indoor temperature and indoor relative humidity to achieve minimum energy consumption for a required indoor thermal comfort level which is evaluated with indoor effective temperature. This method is derived from a central air-conditioning system and is based on our investigation that under a same indoor effective temperature, the system cooling load and the system energy consumption increase with an increase of indoor temperature. As such, energy consumption cannot be reduced with increasing indoor temperature for a given human thermal comfort level. In order to reduce energy consumption while keeping a same indoor thermal comfort level, indoor temperature and relative humidity may be determined with the proposed method described in this article. With the proposed method, a parameter variation study has also been conducted, which suggests that for a given indoor effective temperature, a combination of high indoor relative humidity and low indoor temperature be generally taken. The proposed method is based on the central air-conditioning system; yet it can be easily extended to other systems. 相似文献

This paper describes research into the optimal operation of building heating, ventilation, and air-conditioning (HVAC) systems focusing on both temperature and humidity control. While most previous work on HVAC optimization has been limited to evaluation of conventional temperature-based control systems, this study emphasizes the humidity control issue in meeting both sensible and latent building loads. The analysis is based on a combination of a realistic simulation of a direct expansion (DX) air-conditioning system and a direct-search numerical optimization technique. The simulation models have been validated through comparisons with field data. Optimization was performed on five different system control variables to minimize system power consumption while meeting building loads and maintaining comfort. Indoor temperature and humidity are also optimized within standard comfort constraints. Building loads were modeled using an extended bin method that allows consideration of the interactions between loads and indoor conditions. Results indicate that minimum energy use typically occurs at low airflow rates, with indoor humidity levels below the upper comfort limit. Results also show that coil air bypass and evaporator circuiting control are typically not necessary unless operation would otherwise result in overcooling. The optimization results also translate to relatively simple strategies for system control. Significant savings are demonstrated over conventional control strategies used in packaged DX equipment. 相似文献
