Box Type Condensing Unit Supplier

1. Core Product Principles

1. The compressor sucks in the low-pressure superheated refrigerant vapor discharged from the evaporator, and compresses it into high-temperature and high-pressure vapor, which is the power core of the refrigeration system;
2. The high-temperature and high-pressure vapor enters the condenser, exchanges heat with the cooling medium (air or water) through the integrated heat exchange structure in the box, and condenses into saturated or subcooled liquid;
3. The liquid refrigerant is throttled and depressurized by the throttle valve to become a low-pressure and low-temperature gas-liquid mixture;
4. The mixture enters the evaporator to absorb heat from the cooled medium and vaporize, and then is sucked into the compressor to complete the cycle, continuously providing cold sources.

2. Core Performance and Product Highlights

2.1 Common Core Performance

• Compact structure: The box-type integrated design greatly reduces the occupied space, facilitating flexible layout in various scenarios such as factory buildings and cold storage machine rooms;
• Excellent energy efficiency: By optimizing the ratio of compressors and condensers, most products meet the first-class energy efficiency standard, which can significantly reduce energy consumption costs during long-term use;
• Strong stability: The closed box effectively isolates external dust and corrosive gases. The equipment is pre-commissioned before leaving the factory, and can be started only by simple wiring and pipe connection on site.

2.2 Exclusive Highlights of Kaidi Products

• Customized adaptation: It can provide multiple specifications and models from 35 HP high-temperature type to 50 HP low-temperature type according to different working condition requirements, adapting to different scenarios such as food processing and cold chain logistics;
• Environmental protection and energy saving: It supports a variety of refrigerants such as R22 and carbon dioxide. Among them, the carbon dioxide unit has achieved a dual breakthrough in environmental protection and energy efficiency, helping the industry's green transformation;
• Intelligent management and control: Equipped with an Internet of Things intelligent main board, it supports mobile phone remote monitoring and automatic hot gas defrosting function, with small storage temperature fluctuation and reduced manual intervention costs;
• Quality certification: The full range of products has passed CQC China Quality Certification. According to the calculation of the enterprise's high-standard laboratory, the electricity cost can be saved by more than 27,000 yuan within an 8-year service cycle.

3. Application Case Scenarios

• Cold chain logistics: It provides stable cold sources for cold chain warehousing centers of enterprises such as GLP, SF Express and JD.com, ensuring the low-temperature environment of fresh and pharmaceutical products during storage and transportation;
• Food processing: It is adapted to the production workshops of enterprises such as Wufeng, Holliday, Ligao and Qingmei, meeting the refrigeration needs of meat slaughtering, dairy product processing and baking raw material storage;
• Agricultural planting: It serves edible fungi factories such as Xiangru Biological and Guiwang, accurately controlling the temperature and humidity of the planting environment, and helping the standardized cultivation of fungi;
• Pharmaceutical industry: It provides constant temperature refrigeration solutions for the pharmaceutical warehousing facilities of enterprises such as Shanghai Pharmaceuticals and China National Pharmaceutical Group, complying with the strict standards of the pharmaceutical cold chain.

5. Maintenance Guidelines

5.1 Daily Maintenance Points

• Regular cleaning: Air-cooled units need to clean the dust on condenser fins monthly; water-cooled units need to regularly check the quality of cooling water to avoid scaling affecting heat exchange efficiency;
• Oil management: The refrigerating oil should be replaced in stages 1 week, 15 days and half a year after installation and commissioning; the refrigerating oil should be supplemented in time after compressor maintenance;
• Pressure inspection: Observe the high and low pressure of the system weekly to ensure it meets the operating standards corresponding to the refrigerant (e.g., the high-pressure protection value of R22 refrigerant is usually 2.4MPa);
• Component inspection: Check the operation status of crankcase heaters, solenoid valves, high and low pressure controllers and other components monthly, and handle abnormalities in a timely manner.

5.2 Regular Maintenance Cycle

5.3 Maintenance Under Special Working Conditions

• Shutdown in winter: The water in the condenser of water-cooled units should be drained to avoid freezing and damaging the equipment;
• Long-term shutdown: Close the liquid outlet valve of the liquid receiver, start the compressor to collect the refrigerant into the condenser or liquid receiver, and then close the suction valve;
• Restart requirements: After shutdown for more than 72 hours, the crankcase heater should be preheated for 8-12 hours before starting to prevent compressor damage.
