According to the cooling area of the condenser, match the compressor model:

1. Calculation method of heat exchange area of air condenser

For example: (3ss1-1500 compressor)CT=40℃ : CE=-25℃ compressor refrigerating capacity =12527W+ compressor motor power 11250W=23777/230= air condenser heat exchange area 103m2

2. The ratio of heat exchange area of water condenser to air condenser = estimated ratio 1 to 18(103/18)=6m2

Evaporator area according to the compressor refrigerating capacity (evaporation temperature ℃ x Δ t relative humidity are coefficient of look-up table).

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

There is a freezer

1) library temperature 35 ℃

2) quick-freezing amount 1T/H

3) within time 2/H

4) quick-frozen substance (fresh fish)

5) ambient temperature 27℃

6) calculation of insulation board of equipment maintenance mechanism: 62℃×1000/2/H×0.82×1.23=31266 kcal/n
