Cold storage aluminum busbarCooling capacity of the evaporator The cooling capacity of the aluminum fin evaporator is based on the K value ≈ 10W/(m²·°C) [average value] determined by the National Commercial Equipment Quality Supervision and Inspection Center, calculated from the test report, and is scientifically based. According to the cold storage design specifications, Q = K·FΔt. In the actual matching process, the temperature difference Δt is taken as 10°C. Therefore, the cooling capacity of the aluminum fin is 100W/m². Aluminum fin configuration Calculate the aluminum fin heat exchange area based on the equipment load.

Calculation of cooling equipment load: You can refer to relevant cold storage design manuals for detailed calculations. The formula is as follows: Qq = Q1 + P·Q2 + Q3 + Q4 Qq — Cooling equipment load for cold rooms, W; Q1 — Heat transfer through maintenance structures, W; Q2 — Heat from goods, W; Q3 — Heat flow from ventilation and air exchange, W; Q4 — Operational heat flow, W; P — Load factor. For cooling rooms and freezing rooms, P is 1.3; for other cold rooms, P is 1.0; By substituting the known technical parameters into the above formula, you can obtain the cooling equipment load of the cold storage, that is, the refrigeration capacity the evaporator needs to provide. Large cold storage facilities should strictly follow the above calculation process.
