การออกแบบระบบปรับอากาศที่เหมาะสมสำหรับตู้ฟักไข่ที่ใช้ในอุตสาหกรรม / วิโรจน์ เอกวงศ์มั่นคง = Optimum design of an air conditioning system for industrial incubators / Wiroj Ekwongmunkong
Incubator is a device that provides the suitable air condition for hatching and increases the amount and quality of hatched chickens in response to the market. However, Thai suppliers have to purchase imported incubators in high price and these incubators are not designed for Thailand’s climate, which will increase the energy consumption. Therefore, designing incubators for domestic use will save the energy and reduce the cost of purchasing imported incubators The objective of this research is to design air conditioning system of incubators with the capacity of 103,680 eggs at a time and the size of 5.35 x 5.35 x 2.48 meter (W x L x H) to maintain the suitable air condition for hatching and compare this designed system according to design criteria for the most suitable system The result shows that the most suitable system contains two parts. The first part contains heating coil, water spray, and the second part is a dedicated outdoor air unit that includes air filter, cooling coil, heat pipe, run around coil heating coil and water spray. The system will be able to adjust the air condition in the incubator to maintain the range of 36.5-38.0 , 50-65%RH and maintain the acceptable Carbon dioxide level according to design criteria. It can manage the air condition in the incubator’s peak load with easy care, the lowest life cycle and electric consumption cost.
