寒区部队营房最佳采暖温度和通风量的研究

STUDY ON COMFORTABLE TEMPERATURE AND VENTILATION OF TROOP BARRACKS IN COLD AREA

本文选择驻东北三省部队营房，进行了住室微小气候和人员舒适程度的调查。结果表明，穿着棉衣（隔热值２．７ｃｌｏ），平均皮温２８．７±１℃～２７．３±１．２℃，胸额温差３．０～５．０℃，微小风速平均０．０６９ｍ／ｓ时，８０％人员感到舒适的最佳采暖温度为１６～１８℃。经测定寒区部队营房冬季自然通风量为２０．７～５２．０ｍ￣３／ｈ，换气次数为０．１８～０．７３次／ｈ。在此基础上，加开一小气窗，每小时开窗１０ｍｉｎ，可使换气次数达到０．８次／ｈ的要求。

he microclimate and comfortable degree in house of trood barrackswere investigated in three North-Eastern provinces. The results showedthat(1)the average skin temperature of persons in cotton,padded clothes(heat insulation value is 2.7 clo)was 28.7±1～27.3± 1.2℃,temperaturedifference between forehead and bosom was 3.0～ 5.0℃;(2)when the averagetiny wind speed was 0.069m/s,the optimum temperature at which 80percent of persons feeling comfortable was 16～18℃:(3)in winter, theamount of ventilation detectable in houses was 20.7～52.0m￣3/h and ventila-tion times was 0.18～0.73/h. On this basis,if a small transom windowwasopened in 10 minutes per hour, then the frequency of ventilation of 0.8per hour could be met.
