Energy Saving Research On The Enclosure Structure Of The Factory Circulating Water Aquaculture Workshop

With the continuous expansion of fisheries and aquaculture,the growth rate of industrialized aquaculture is far higher than that of traditional fishing fisheries.With the rapid development of industrialized aquaculture,there are no clear norms and standards for energy conservation practices in the enclosure structure of aquaculture workshops,resulting in severe heat loss in the enclosure structure of aquaculture workshops;In order to solve the above problems,this paper takes the aquaculture workshop of Dalian Fugu Fisheries Co.,Ltd.as an example to study the energy conservation of the enclosure structure of the aquaculture workshop.This article compares and analyzes common energy consumption simulation software at home and abroad,summarizes the advantages of each energy consumption simulation software,and introduces the methods and theoretical knowledge for studying building energy conservation.Use sketchup to model aquaculture workshops,and Energyplus to simulate energy consumption.Through the annual hourly energy consumption simulation of roof,daylighting panel,exterior wall,exterior window and ground,the energy consumption distribution of the workshop enclosure structure is analyzed.The energy consumption of roof,daylighting panel,exterior wall,exterior window and ground accounts for 40.83%%,40.10%,10.23%,5.00% and 3.84%respectively.The economic analysis of the enclosure structure practices under different heat transfer coefficients is carried out to select an economic and energy-saving enclosure structure scheme,That is,glass fiber insulation layer is selected as roof insulation material,and the energy saving efficiency is increased by 17.79%;polycarbonate PC board is selected as daylighting plate,and the energy saving efficiency is increased by 33.04%;60 series bridge cutoff aluminum casement window and 6mm low-e glass are selected as external windows,and the energy saving efficiency is increased by 30.26%;polyurethane rigid foam is selected as external wall insulation material,and the energy saving efficiency is increased by 29.37%;molded polystyrene foam is selected as ground,and the energy saving efficiency is increased by 21.3%.Under the condition that the volume of the workshop remains unchanged,the shape coefficient is adjusted by changing the ratio of the length,width,and height of the workshop.Simulate the energy consumption of workshops with different shape coefficients,and ultimately conclude that the most energy-saving scheme is a workshop with a shape coefficient of 0.1 to0.25 and 0.4.Under the shape coefficient with the lowest energy consumption,change the area ratio of windows in the same orientation to simulate workshop energy consumption under different window to wall ratios.The simulation results show that the larger the window to wall ratio,the less conducive to energy conservation.Therefore,during design and construction,on the premise of meeting the use requirements,the smaller the area ratio of windows in the same orientation,the more energy conservation.Under the optimal shape coefficient and window to wall ratio,the energy consumption of workshops with different roof forms was analyzed,and the results showed that the slope roof saved 4.7% energy compared to the curved roof.
