It is radiator heating system ,w ith radiator heating system to95℃/70℃hot water as heat medium, mechanical cycle for reference next time vertical single-pipe heating system. First, calculates the system thermal load ,the whole is . on this basis, parison of the radiator , the performance good and economy M-132 type heat sink was selected. Thanks for reference next time single-tube system, according to the room heat load can be calculated for each heat sink required for the number of houses. For system piping design, drawing floor plans and system map layers. For hydraulic calculation, find the parallel circuit of the unbalanced rate, the rate for the large imbalance in parallel with the riser pipe to throttle valve. In the hydraulic calculation on the basis of rational choice selection of exhaust valve, decontamination equipment, devices and other accessories. K ey words: heating; h eat load calculations ;r adiator selection and calculations ; s ystems design ; hydraulic calculations 5 目录概述.............................................................................................................. 1 第1章计原始资料...................................................................................... 3 设计题目.........................................................
