Classification application
The warm water lithium bromide absorption chiller uses factory waste hot water, urban pipe network hot water, hot water produced by hot water boilers as heat sources, and provides cold water for air conditioning or processing.
The unit is safe and reliable, maintains high efficiency for a long time, can use waste heat, improves the environment, and is conducive to the comprehensive utilization of energy.
Main scope of application
Factory air-conditioning: air-conditioning and refrigeration in factory buildings
Process cooling: used in processes that require cold water
For district cooling room: as a refrigeration source of district air-conditioning
Combined heat, power and cooling system: use the high temperature drainage of the heat and power company as the driving heat source for cooling, comprehensively utilize energy, and improve the thermal efficiency of the system.
Refrigeration range: 35KW-9302KW
Heat source conditions: waste hot water produced by the process of the factory, the cooling water of the generator cylinder in the thermoelectric industry, etc., 65-99℃; low-temperature hot water can be used, the temperature difference can reach 20℃, and the waste heat utilization rate is high; Heating network, etc., 100-140℃; heat source water temperature difference can reach 62℃, maximum use of heat source; high temperature hot water produced by factory process, high temperature drainage of thermal power plant, etc., 130-190℃.
Salient features:
Safety control according to the cooling water temperature: For the change of the cooling water temperature of 19-34℃, safety control is carried out, and high-efficiency operation can be carried out for a long time. The safety control uses a microcomputer to calculate the concentration of the absorbing liquid during operation to control the warm water absorption chiller to perform a circulating operation suitable for the current cooling water temperature.
High-vacuum long-term maintenance system is adopted to further improve the reliability performance: high-performance air extraction system; direct sealing structure, strong air tightness.
The absorption liquid pump adopts frequency conversion control to provide part-load characteristics: absorption chillers have a great influence on energy consumption due to the circulation volume of the absorption liquid. Therefore, Sanyo uses a patented frequency conversion device to control the absorption liquid pump, so that the circulation volume of the absorption liquid is suitable for the cooling room load, and energy-saving operation is effectively carried out. Moreover, because the circulation amount is controlled in the best state, the starting time is shortened by about 1/2. This greatly exerts the energy-saving effect.
Anti-crystallization safety control: The computer monitors the concentration of the absorption solution at any time, and when the concentration reaches a certain value or more, it controls the consumption of warm water and reduces the concentration of the absorption solution. It can quickly control and prevent the occurrence of solution crystallization during operation under the conditions of emergency speed change, and realize stable anti-crystallization operation.
Maintenance predictive function: the pumping signal, through the pressure sensor of the pumping device, will give a preview when the pumping operation is required.
Operation and maintenance data management function: Use various sensors to read and memorize the operation data to accurately grasp the maintenance situation.

The significance of maintenance before starting the water chiller
The performance and service life of lithium bromide absorption refrigeration units are not only closely related to the startup, commissioning, and daily operation management of the units, but also closely related to the maintenance and repair of the units. As the saying goes, "The quality of a device is divided into three parts, and the maintenance is divided into seven parts." It can be seen that timely maintenance plays a very important role in the efficient operation of the unit.
Although there are many operating components and linkage equipment for refrigeration units, as long as preventive management is carried out in a planned manner, such as startup maintenance, daily maintenance, shutdown maintenance, etc., the unit can be kept in good operating condition.
Steps and Significance of Preventive Management (Maintenance) for Aircrew
01 Unit control part
Check and confirm the unit control system to improve the reliability of unit operation;
02 Unit vacuum part
Check the air tightness of the vacuum system to ensure the operation effect of the unit;
03 Safety protection device
Verification and maintenance of the action sensitivity of safety accessory devices (flow switches, pressure switches, temperature sensors, etc.) to ensure the safe operation of the equipment;
04 Mechanical part
Check the medium transmission devices at various parts of the unit, including whether the transmission components, current, voltage, and ground insulation of the shield pump are normal;
