Description

Designed for the specialty “Heat and gas supply and ventilation” and related ones. The stand is a frame structure with three types of heating devices installed in thermally insulated cells: convector, radiator, smooth pipe. Water is heated to a given temperature in a boiler and supplied to the piping system and heating devices by a pump. The system of pipelines and switching elements allows testing heating devices when implementing various switching schemes. Liquid consumption is measured by a flow meter made on the basis of a hot water meter, the temperature at control points is measured by temperature sensors. Information is output to the instrument panel and to a personal computer (laptop) with a DAC-ADC board for recording information. List of laboratory works: 1. Determination of heat transfer from a convector 2. Determination of heat transfer from a radiator 3. Determination of heat transfer from a pipe 4. Determination of the shading coefficient into the device with an axial closing section with a diameter of 20 mm 5. Determination of the shading coefficient into the device with a displaced closing section with a diameter of 20 mm 6. Determination shading coefficient into the device with an axial closing section with a diameter of 15 mm 7. Determination of the hydraulic characteristics of the convector 8. Determination of the hydraulic characteristics of the radiator 9. Determination of the hydraulic characteristics of the pipe
