摘　　要：为了研究空气载能辐射空调应用于实验动物房中,对动物福利以及空调系统节能的影响,采用Fluent软件对传统上送下回式空调系统及空气载能辐射空调系统的运行状态进行数值模拟.对比分析了相同换气次数下的风速、温湿度、氨气浓度的分布差别以及空气载能辐射空调不同换气次数对室内风速、温湿度、氨气浓度变化的影响.结果表明,空气载能辐射空调使实验动物房内的温度梯度保持在0.46℃/m以下,相对湿度能保持在40%~70%,且因为新风量的控制在一定程度上能改善实验动物房能耗过高的问题.这为实验动物的福利保障以及实验动物房的节能提供了参考.In order to study the effect of the application of air carrying energy radiant air-conditioning system(ACERS)in laboratory animal rooms on animal welfare and energy saving of air-conditioning system,Fluent soft⁃ware is used to numerically simulate the operating state of traditional air-conditioning system and ACERS.The distri⁃bution differences of wind speed,temperature and humidity and ammonia concentration under the same ventilation times,and the effects of different ventilation times of ACERS on indoor wind speed,temperature and humidity and ammonia concentration are compared and analyzed.It is found that the ACERS can keep the temperature gradient in the laboratory animal rooms below 0.46℃/m and the relative humidity between 40%~70%,and because the control of fresh air can improve the problem of high energy consumption in the laboratory animal rooms to a certain extent.This provides a reference for the welfare of laboratory animals and the energy saving of laboratory animal rooms.
