The main engine of the refrigeration unit adopts the domestic well-known brand host Bits, Brocade/FS/Hanzhong brand, which is widely used in China, with low failure rate and stable and reliable operation.
High refrigeration efficiency and refrigeration speed
Fast All refrigeration units adopt the overall optimized design scheme to reduce the refrigeration loss in the pipeline ratio and ensure the refrigeration efficiency after the unit is assembled.
Strong compatibility, running sections
Strong performance Multiple warehouses use parallel refrigeration units, each compressor can provide multi-stage energy adjustment, the cooling output can be more stable and dynamically match the actual load, strong compatibility, and strong energy saving operation.
Low-noise shock-absorbing design
The reasonable design of the pipeline and the installation of shock absorbers reduce the noise caused by the high-pressure gas vibration pipeline and improve the reliability of the compressor operation.
Unit
The full protection includes reversed-phase sequence, overpressure, underpressure, oil pressure, high pressure, low pressure, electronic low liquid level, low oil level, overload, exhaust temperature protection, high and low oil temperature, etc., with complete protection functions and increased the stability and safety of the unit.
Highly reliable oil level control
With a high-efficiency centrifugal oil separation and return system, the oil discharged from the compressor is separated in the high-efficiency oil and stored in the oil storage tank, and the oil level regulator that controls the oil level of each compressor can evenly supply the oil from the oil storage tank to the compressor system as needed.
Complete safety device design
In order to ensure that local faults do not affect the whole, segmented and sub-regional control shut-off valves are set in refrigeration pipelines such as oil circuits, gas pipelines, and liquid pipelines to avoid a large amount of freon losses in the maintenance process.
Advanced intelligent design
PLC controller: The energy output program can be compiled according to the system requirements to ensure that the output energy of the unit is dynamically matched with the actual system load to the greatest extent, so as to achieve the purpose of high efficiency and energy saving.
PLC controller: real-time monitoring of the compressor unit, which not only improves the efficiency, but also prolongs the system life.
The unit runs or stops under the control of the PLC controller, and the running time is accumulated regularly to achieve balanced wear and prolong the service life of the compressor unit.
Selection
The main electrical components of the fine refrigeration unit are Schneidr and Chint brands, the control PLC is Siemens brand, and the touch screen of the unit is Weilun brand;
The key components in the unit are all imported components, which ensures the design requirements and high stability, safety and reliability in the operation of the unit. Compared with other refrigeration compressors, the cost of replacing wearing parts and daily maintenance is reduced, and the investment cost of later operation is greatly reduced.
High standard manufacturing process
Strict manufacturing process, all pipes and containers of the unit are strictly derusted, cleaned and purged before assembly to ensure that the inside of the unit is clean;
After the completion of the whole machine, the whole machine shall be tested for pressure holding and strict sewage discharge shall not be less than 48 hours to ensure that the unit has no leakage and internal cleanliness.
Reliable unit standardization and user-friendly design
The unit is set to automatic/manual mode, and the operation mode can be switched according to the needs of use;
The arrival of this unit is indispensable, with a small footprint and easy to install and use.
Multi-stage energy regulation is provided, and the cooling output dynamically matches the actual load.
The unit adopts high-quality semi-hermetic screw compressors, such as GEA, BIZER, Fusheng, etc.,
The use of high-efficiency centrifugal + liquefied oil separator minimizes the possibility of oil entering the system.
Two types of oil supply (differential pressure and pump forced) ensure that each compressor receives an adequate supply of lubricating oil under all operating conditions.
The whole system adopts PLC intelligent control, with multiple protection functions such as phase sequence (ohase loss), overload, pressure overshoot safety, oil level, oil flow, oil pressure difference, etc., and the highly integrated design concept greatly saves the area of the computer room.
