Case of refrigerating unit for 2000 cubic cold storage

1. Project content: a customer has a demand, one cold storage, 2025 cubic meters. For storing fruits, the temperature is 5-10 degrees Celsius. The customer has no requirements for the compressor brand, but only requires high cost performance, stable and reliable quality, and no detailed plan in advance.

2. Design idea: This is an entire cold storage, so it is most suitable to choose a modular unit. Zhejiang Bitzer compressor is a domestic first-line compressor brand in the field of refrigeration and refrigeration, which is cost-effective, stable and reliable. According to the KUB cold storage selection software, (according to the mechanical load calculated by the medical cold storage, the evaporation temperature is minus 5 degrees, the condensation temperature is 40 degrees, and the unit selects 2 sets of 25HP V box ejector fan units for high temperature units), Baoku D type cold air The machine is a domestic first-line brand. In order to make the airflow distribution in the cold storage even, choose 1 unit to drag 2 air coolers. Considering the cold storage span is relatively large, choose the air cylinder type air cooler with a range of 16 meters (according to the cold storage load calculated by the medical cold storage, evaporation The temperature is minus 5 degrees, the condensing temperature is 40 degrees, and the sheet distance is 6mm. There are two sets of units in a cold storage. The best solution is the control box NAW162 of one storage and two machines, which can be installed at one point. The temperature controls the on and off of the two compressors, the on and off of the two sets of air coolers, and the defrosting time and frequency of the 2 sets of air coolers. The two sets of air coolers can be turned on at the same time, or one can be used and one standby. It can also realize the failover of the chiller fan of the unit. It can also be connected to the Internet, remotely switch the machine, remotely view the current of the unit, remotely diagnose and eliminate the fault.

4. Customer evaluation: This customer is an owner. After many comparisons, we finally chose our solution. After on-site installation by our recommended installer, our engineers on-site commissioning and guidance, it takes only 48 minutes to drop from room temperature 25 degrees to 5 degrees. Yes, high voltage 15KG, low voltage 4KG, current 35A, the failover test machine is normal, the remote monitoring test machine is normal, and the customer is very satisfied.
