simple calculation method of portable air conditioner coolers chillers

Selection of cold storage chiller According to the cold storage area plus the choice of compressor specifications and models to calculate the selection of portable air conditioner coolers chillers, different temperature models and specifications of portable air conditioner coolers chillers are different portable air conditioner coolers chillers, small series of various types of cold storage room temperature calculation method for the user reference.


First, the cold storage refrigerator to match the chiller (DD-type cooler):

Load per cubic meter by W0 = 75W m3 calculation.

1, if the V (cold storage capacity) <30m3, open the door more frequently the number of cold storage, such as fresh meat library, the multiplication factor A = 1.2;

2, if 30m3 ≤ V <100m3, open the door more frequently the number of cold storage, such as fresh meat library, the multiplication factor A = 1.1;

install portable air conditioner


3, if V ≥ 100m3, open the door more frequent cold storage, such as fresh meat library, the multiplication factor A = 1.0;

4, if a single cold storage, the multiplication factor B = 1.1 The final selection of cold storage chiller by W = A * B * W0 (W for the cooling fan load);

5, cold storage refrigeration units and portable air conditioner coolers chillers match the evaporation temperature calculated by -10oC.

Second, the cold refrigerator to match the chiller (DJ-type cooler):

Load per cubic meter according to W0 = 70W m3 calculation.

1, if the V (cold storage capacity) <30m3, open the door more frequently the number of cold storage, such as fresh meat library, the multiplication factor A = 1.2;

2, if 30m3 ≤ V <100m3, open the door more frequently the number of cold storage, such as fresh meat library, the multiplication factor A = 1.1;

3, if V ≥ 100m3, open the door more frequent cold storage, such as fresh meat library, the multiplication factor A = 1.0;

4, if a single freezer, then multiplied by the coefficient B = 1.1 The final optional cold storage chiller press W = A * B * W0 (W for the cooling fan load)

5, when the cold storage and cold storage cabinets shared unit, the unit and the cooling fan match -35oC evaporation temperature calculation. When the cold storage and cold cabinets separate, cold storage units and portable air conditioner coolers chillers match -30oC evaporation temperature calculation.

Third, cold storage processing between the matching of the cooler (DL-chiller):

Load per cubic meter according to W0 = 110W m3 calculation.

1, if V (inter-processing volume) <50m3, the multiplication factor A = 1.1;

2, if V ≥ 50m3, the multiplication factor A = 1.0 The final cold storage chiller matching W = A * W0 (W for the cooling fan load);

3, when the processing room and the temperature shared with the refrigerator unit, the unit and the cooling fan to match the evaporation temperature calculated at -10oC. When the processing room and separated from the temperature cabinet, cold storage units and portable air conditioner coolers chillers at 0oC evaporation temperature matching calculation
