1 Alex's brief introduction Majored in Electrical and Computer Engineering 主修电气与计算机工程
16 years experiences in heating system for animal husbandry 畜舍加热行业长达16 年的工作经验 Started a JV in China in
2015 2015年在中国创立了合资公司DAMLY DAMLY is a JV between DAOU and MARLIS in France.
The factory is located in Zhengzhou. 大欧美丽DAMLY是由法国 玛力士公司与郑州大欧畜牧设 备有限公司共同投资成立的中 法合资企业.工厂坐落在河南 郑州

805 762 2.57 2.69 Effect of the temperature on the pig growth 温度对猪生长的影响 80g extra food per day is necessary at 17°C to obtain the same growth than at 24°C, corresponding at
7 kg of extra food per pig to fatten them from
25 Kg to
108 Kg. 温度在17°C时想要达到与温度24°C时同样的重量,猪每天需要多摄入80g 的饲料.也就是说育肥猪从25kg到108kg,每头猪需要多摄入 7kg的饲料.
6 EFFICIENCY OF THE DISINFECTION (maternity, post weaning, fattening)消毒效率 (哺乳、保育和育肥) Total flora (in number of colony) 总菌群(以菌落来计数) Day 天数 Room 舍内加热情况 Average 平均菌落数 number of sites done 试验点数量 Day+2 heating加热

35 102 Heating interest on the efficiency of the disinfection 加热对消毒效率的作用
2 days after disinfection, most of the heated room have a lower bacterial and fungal contamination than the no heated room. 消毒两天后,加热猪舍的菌落数和真菌感染几率比未加热的要低很多 It was also observed during the test concerning the post weaning room an average of number of colony :
7 in heated room against
43 in no heated room.
7 Energy consumption comparison between China and France 中国和法国的能源消耗对比 66% of energy comes from coal in China 中国66%的能源来自煤 In France, whitin
43 years, gas energy goes from 5.7% to 22% and coal represents only 4%. 在法国,43年来,燃气能源从5.7%上升到22%,煤仅占4% We don't use coal in France to heat pig 在养殖上,我们从来不用煤

13 Coal pollutes around two times more than gas 燃煤污染是燃气的约两倍
9 The four heating systems existing today : 目前现有的4种加热产品: ? Coal boiler燃煤锅炉 ? Diesel heater柴油加热器 ? Electric heater电加热器 ? Gas heater 燃气加热器
10 Coal Boiler 燃煤锅炉
11 Diesel heater 柴油加热器
12 Electric heater 电加热器
13 Gas heater 燃气加热器
14 GAS HEATER : SUNHEATER COAL BOILER Liquid Propan is 3,5 times more powerful than coal :
1 Kg =
14 kWh Coal is 3,5 times less powerful than liquid Propane :
1 Kg =
4 kWh Sunheater : Direct air to air combustion : 0% loss Air and water coal boiler : 40% loss Flexibility, the gas heater run automatically and doesn't need big maintenance. It switch off instantly when the room is at the good temperature Not flexible, a coal burning boiler will have to run fully once it has started even if the room is at the right temperature : average 25% fuel waste The combustion of gas is very clean especially with natural gas. Our gas heater can also burn your biogas As we saw before the combuistion of coal is not good and the coal boiler can only burn coal. Heat transportation = 20% loss Air to water heat transfer = 20% loss
14 燃气加热器 : 大欧热霸 燃煤锅炉 液化气产能是煤的3.5倍:1Kg =
14 kWh 煤产热量比液化气少3.5倍:1Kg =
4 kWh 大欧热霸:直接加热空气 燃烧零损耗 水暖锅炉:损失40%的热量 灵活性:大欧热霸全自动化控制,减少人力.当温度达到 所需温度时自动停止工作. 灵活性差:燃煤锅炉一直在工作并且很难维持所需温度: 平均有25的燃料被浪费 燃气环保无污染 我们的加热器还可以使用沼气 燃煤污染大气 管道传输中损耗 20% 空气到热水转 换损耗 20%

130 watt/m? Example :
600 piglet with a room of
230 m? =
30 000 watt 冬天室外温度-15°C时: 50w/仔猪 或130w/m? 举例: 一个230 m?600头仔猪的保育舍,所需加热功率是30kW How to calculate the heating power you need 如何计算你需要的加热功率
17 Link between ventilation and heating temperature 通风系统与加热系统的关系
18 Key aspects for the gas heater 燃气加热器的重要因素
19 Key aspects for the gas heater 燃气加热器的重要因素
20 Heat recovery 热交换器 ? Reduce the gas consumption from
60 to
80 % 减少60-80%的耗气量 ? The air which comes into the room is preheated so you don't have a fall of cold air on the piglet 进入舍内的空气被预热,防止冷风吹到仔猪身上 ? Put out CO2 and Humidity 去除CO2和湿气 ? Good air quality: 良好的空气质量 Humidity湿度H: 60-70% NH3: 5-20ppm CO2:
