การทดสอบฉนวนกันความร้อนสำหรับหม้อต้มน้ำไฟฟ้าด้วยวิธีไฟไนท์อิลิเมนท์

Abstract

         This article presents thermal insulation testing for electric water boilers using the finite element method.  Simulation of heat distribution results in an electric boiler. In the case of not insulating and insulated with fiberglass.  The operation of the electric boiler was tested and heat transfer data was collected using a thermal imaging camera. The simulation results found that the insulation Can reduce heat dissipation from the electric boiler. Testing the operation of the electric boiler It is a test of boiling water until the water boils and the boiler stops working. Then record the electrical energy used. The time when the boiler is working and the temperature on the surface of the electric boiler is measured. Test results found that Insulating makes an electric boiler more electrical energy about 0.01 unit and the boiler takes less time to run than if it were not insulated. The simulation results using the finite element method and the tests are in the same direction.
