Calculation Method of Heat Transfer Area of Condenser

2018-09-25 10:47

1. Calculation method of heat exchange area of air condenser

Refrigerating capacity compressor motor power/200~250 = condenser heat exchange surface e.g.:(3SS1-1500 compressor) CT = 40 ℃:CE =-25 ℃ compressor refrigerating capacity = 12527W compressor motor power 11250W = 23777/230 = air condenser heat exchange area 103m2

2. Ratio of heat exchange area of water condenser to air condenser = budget estimate 1: 18(103 /18)= 6m2

The area of the evaporator is based on the cooling capacity of the compressor (look-up table of the positive coefficient of evaporation temperature ℃×Δt relative humidity).

3. Calculation method of cooling capacity: = temperature difference × weight/time × specific heat × equipment maintenance organization

For example: there is a frozen library

1) Warehouse temperature -35 ℃

2) Quick-frozen volume 1 T/H

3) Within time 2/H

4) Quick-frozen material (fresh fish)

5) Ambient temperature 27 ℃

6) calculation of insulation board of equipment maintenance organization: 62 ℃ × 1000/2/h × 0.82 × 1.23=31266 kcal/n compressor evaporation temperature CT = 40 CE-40 ℃ refrigerating capacity = 31266 kcal/n
