This controlled atmosphere cold room project was undertaken by Haocool refrigeration Hangzhou branch. The cold storage has two air-conditioned cold rooms with a volume of 600 cubic meters and a refrigeration room with a volume of 300 cubic meters. The total project scale is 1000 cubic meters. Cold storage temperature is 0 ℃ -5 ℃. The unit is furnished with polyurethane double-sided color steel cold storage board (density 0.5, thickness 150mm). Included is a United States manufactured Copeland fully enclosed Emerson unit, Haocool air cooled chillers, Haocool cold storage control box, LED high temperature and low temperature moisture-proof special lights for cold storage, temperature and humidity recorder, and a comprehensive air conditioning control system.
Customer Problems: Due to the poor effectiveness of fruit preservation, the original cold storage resulted in a short storage cycle, decline of fruit quality, and diminished sales.
Haocool's solution: Unlike other companies who fill nitrogen to reduce the oxygen content and fail to achieve long-term preservation, our controlled atmosphere cold room selects national standard controlled atmosphere cold room board and air conditioning insulation door. The slab joints are sealed by special sealant and cloth. After the sealing process, air pressure testing is carried out to test sealing performance. The automatic control of the air conditioning equipment reduces the time of staff getting in and out, ensuring the sealing effect.
The cold storage project started on July 15, 2013 and was completed on August 20, 2015. The project has been accepted and affirmed by the customer, and it has been put into use.
