Matching calculation of cold storage & air cooler

   cold storage per cubic meter load by W0=75W/m fand calculation. The freezer per cubic meter load by W0=70W/m fand calculation. Cold storage processing per cubic meter load by W0=110W/m fand calculation.

A.Matching of cold storage & air cooler:
Cold storage per cubic meter load by W0=75W/m fand calculation.
1 if V (cold storage capacity) 30m < fand frequently door number, cold storage, such as fresh meat base, by coefficient A=1.2;
2 if 30m 100m fand < V < fand, frequent cold storage door times, such as meat base, by coefficient A=1.1;
3 if V is larger than 100m of cold storage door times more frequent fand, such as meat base, library, by coefficient A=1.0;
4 if a single cold storage, cold storage coefficient by B=1.1 cooler selection according to W=A*B*W0 (W cooler load);
5 According to -10 deg.C evaporation temperature calculation of cold strage refrigeration unit and air cooler.

B. Matching of freezer & air cooler:

The freezer per cubic meter load by W0=70W/m fand calculation.

1 if V (cold storage capacity) 30m < fand frequently door number, cold storage, such as fresh meat base, by coefficient A=1.2;
2 if 30m 100m fand < V < fand, frequent cold storage door times, such as meat base, by coefficient A=1.1;
3 if V is larger than 100m of cold storage door times more frequent fand, such as meat base, library, by coefficient A=1.0;
4 if a single cold storage, cold storage coefficient by B=1.1 cooler selection according to W=A*B*W0 (W cooler load);

5 When the cold storage and low temperature cabinet shared refrigeration unit, according to the -35 deg.C evaporation temperature calculation of matching unit and air cooler. When separate cold storage and low temperature cabinet, according to -30 deg.C  evaporation temperature calculation in refrigerating units and air cooler.

C. Matching of cold storage processing & air cooler:

1 if V (processing volume) 50m < fand by coefficient A=1.1;
2 if V = 50m is multiplied by a factor of A=1.0 eventually fand, air cooler selection by W=A*W0 (W cooler load) finally;
3 when cold storage processing and medium temperature cabinet shared refrigeration unit, according to the -10 deg.C evaporation temperature calculation of refrigeration unit and air cooler.

When separate cold storage processing and medium temperature cabinet, according to the 0 deg.C  evaporation temperature calculation in refrigerating units and air cooler.
