Generally, the room temperature of residential houses is about 14~18℃, and the relative humidity 50~70%. With consideration of hygienic requirements and economical-technical factor in the design code, the heat transfer coefficient of the inside surface of houses αn has been specified to be 7.5 Kcal/hr·m2 ·deg. for the heat consumption ca-lculation of houses with enclosure heating in winter time. Accordingly, the inside surface temperature of houses has been allowed to be 4~6℃ less than the room temperature,or to be equal to or higher than the dew point of the room atmosphere for the houses with large relative humidities.As to swine houses, the function and the environmental conditions are quite different trom those of residential houses. Under the condition of intensive rearing to fattened pigs, firstly, there is strong radiative-heat exchange between swine body surfaces and the inside surface of the house, so that the inside surface temperature of swine houses approaches to its room temperature. Secondly, swines shall diffuse a large amount of moisture, the relative humidity is higher, so the inside surface temperature of the swine houses should not be lower than the dew point of the room atmosphere. Hence, it's not applicable for the swine houses to specify αn= 7.5 Kcal./hr·m2·deg.This paper takes the Beijing area as an example and calculates the value of αn for swine houses with the following conditions:1. The inside surface temperature is 1℃ lower than the room temperature.2. It's supposed that approximately one half of the swine body surfaces will fake heat exchange by radiation between aceiling and walls.3. The parallelepiped enclosed system that is equivalent to the radiation in swine houses has been used to construct the controlled zone of swines in order to solve the radiation angle coefficient ψi-j.In the process of calculation the effect of heat absorbing by corbon dioxide and water vapor in the swine houses has been put into consideration, too.Through calculation and analysis, this paper recommended that αn, for swine houses may be 21 Kcal./hr·m2·deg. for the ceiling and to 8 Kcal/hr·m2·degfor the walls when calculating the heat consumption of swine faffening houses in winter time. In addition, the minimum thermal resistance Rmin of the swine fattening houses has also been investigated.

居住性民用建筑室内温度一般在14~18℃范围内,相对湿度约50%~70%。设计规范考虑了卫生要求、经济技术因素规定在冬季建筑围护物采暖耗热量计算或其他有关计算中,建筑内表面换热系数采用α_n=7.5千卡/小时·米~2·度。相应地规定建筑内表面温度允许低于室内空气温度4~6℃,对于相对温度较大的房间,通常规定建筑内表面温度不低于室内空气露点温度。 现代猪舍建筑由于使用功能不同,舍内环境条件与居住性民用建筑有显著的差异。肥猪集约饲养,猪体表面与建筑内灰面之间具有强烈的辐射热交换,导致猪舍建筑内表面温度接近于舍内空气温度;其次,在猪舍实际使用过程中,肥猪还散发大量水分。舍内相对湿度偏高也要求建筑内表面温度不低于舍内空气露点温度。居住性民用建筑内表面换热系数α_n=7.5千卡/小时·米~2·度,不适用于猪舍建筑。 本文在如下条件之下以北京地区为例,对采暖的和非采暖的双列式育肥猪舍建筑内表面换热系数α_n进行核算: 1.猪舍建筑内表面温度低于舍内空气1℃。 2.认为猪群的体表面积大约有一半参与和屋顶、外墙内表面之间的辐射热交换。 3.运用与猪舍内辐射等价的平行六面体封闭系统并划出肥猪控制区来求解辐射角系数ψ_(i-l)...

Saturated air solar still is a new distillation device utilizing mainly solar energy,simple in structure and suits for obtaining higher fresh water production under various operating conditions.The experiment studied first for the profile of evaporation velocity under steady state and different heating temperatures for sea water.An equation for profile D=f(t0) was obtained as:It was found that heating temperature is the major factor affecting production,with 46.2℃ as a turning point.The evaporation is accelerated rapidly at the temperatures above this point.Theoretical analyses and experiments proved that liquidgas phase flow ratio byweight should meet the heating temperature of water.Maximum increase of production and lower heat consumption could be achieved only when higher ratio- 3.0 at typical solar radiation.

研究得到了太阳能空气饱和蒸馏器在稳态情况下和不同海水加热温度下的蒸发速度实验式:lgD=7.062+3.446t_0海水加热温度是影响淡水产量的主要因素,以46.2℃为转折,超过此温度,蒸发速度急促增加。液-气两相重量流量比(W/G),必须与海水加热温度相适应。温度较高,(W/G)值也应较大,这样才能最大限度地提高产水量和降低产水的耗热量。当t_0=96℃时,(W/G)_(最佳)=12;当(W/G)=11时,t_(0最佳)=90℃。在一般太阳辐射条件下,t_0=60℃,(W/G)=1.67—3.0时,热耗值最低。过多地通入空气是空气饱和蒸馏器动力消耗较大的重要原因。在适当工况下进行操作,所需空气量较小。这样,不但产水量高、热耗值低、系统阻力减少,而且能耗大幅度降低。 模拟试验表明:太阳能空气饱和蒸馏器在太阳辐射日总量4500〔千卡/米~2〕时,每平方米集热器面积,每日可产淡水5—7公斤,所需翅片冷凝器换热面积为0.21〔米~2/时·公斤淡水〕。
