Wuhan cold aluminum exhaust pipe cold aluminum wings of aluminum tubes manufacturers of aluminum row

Aluminum pipes, mainly used for 10 ℃ to -45 ℃ cold storage refrigeration systems, is all kinds of frozen food, cold storage evaporator used. Aluminum exhaust tube evaporator plant, the snow is still cooling, aluminum and out of the liquid portion of discharge tube using high-frequency resistance welded aluminum joints, 2mm thick aluminum under no difference, pressure 4.5Mpa. Aluminum exhaust steam cooling capacity, K value ≈10W / (m2 · ℃) [mean], according to cold storage design specifications, Q = K · FΔt, taken during the actual ratio of the temperature difference Δt = 10 ℃. The aluminum row of cooling capacity of 100W / m2. Aluminum row evaporator cooling capacity aluminum row evaporator cooling capacity of the calibration is based on the National Quality Supervision and Inspection Center of commercial equipment made K value ≈10W / (m2 · ℃) [mean] calculated from test reports, is a scientific basis. According cold storage design specifications, Q = K · FΔt, taken during the actual ratio of the temperature difference Δt = 10 ℃. The aluminum row of cooling capacity of 100W / m2. Computing device configured to determine load aluminum row aluminum row heat exchanger area cooling load calculation: You can refer to the relevant cold storage design manual for detailed calculations. The following formula Qq = Q1 + PQ2 + Q3 + Q4 Qq - intercooler cooling equipment load, W; Q1 - maintenance of the structure of heat transfer, W; Q2 - cargo heat, W; Q3 - ventilation heat flow, W; Q4 - Operating heat flow, W; P-- load factor. Room cooling, the freezing P take 1.3, among other cold take 1.0; substituted by the above formula known technical parameters can be derived refrigerator cooling equipment load value, which is required to provide the cooling capacity of the evaporator, a large cold storage should be strictly in accordance with the above calculations process.
