Three Parallel Screw Refrigeration Units For Cold Storage -18 Degrees

1. Project content: A customer has - - a demand, 2 refrigerated warehouses, 7040 cubic meters and 5216 cubic meters respectively. The temperature is required to be -18 degrees. According to the calculation, we selected the mechanical load of the external machine to be 367KW, the equipment load of 7040 cubic meters is 211KW, and the equipment load of 5216 cubic meters is 156KW.

2. Design ideas: This is two logistics warehouses, and it is most suitable to use 3*125HP screw units. Beijing Bitzer screw compressors are the domestic brand of compressors in the field of refrigeration and refrigeration. They are cost-effective, stable and reliable. According to the selection software of Kubao cold storage, (according to the mechanical load calculated by the cold storage, the evaporation temperature is minus 25 degrees, the condensation temperature is 40 degrees, and the unit is selected as a low-temperature unit 3*125HP screw unit
1 set of modules, the condenser is installed in a split type, the evaporative condenser is 1620KW), and the Baoku D-type air cooler is a domestic brand. 4 sets of air coolers, choose the air cylinder type air cooler with a range of 25 meters (according to the cold storage load calculated by the cold storage, the evaporating temperature is minus 25 degrees, the condensation temperature is 40 degrees, and the film spacing.
6mm is selected, hot gas defrosting), the start and stop of the screw unit is controlled by pressure, and the unit comes with a control box. There are 4 air coolers in a cold room at the end. In order to consider the reason for defrosting, the end
The solution for the cooling fan is to use PLC programming, which can control the start and stop of the 4 groups of cooling fans in the No. 1 cold room according to the temperature of the No. Control the start and stop of the 4 groups of cooling fans in the No. 2 cold storage, and control the defrosting time and times of the 4 groups of cooling fans respectively.

3, the selection plan

4. Customer evaluation: This customer is an owner. After many comparisons, we finally choose our solution. After on-site installation by our recommended installer and on-site debugging guidance by our engineers, the shutdown from normal temperature 25 degrees to -18 degrees only takes 2 hours It's ok, high pressure 15KG, low pressure 1.5KG, the remote monitoring test machine is normal, and the customer is very satisfied.
