An online manageable air-cooled screw chiller and management system

Abstract

The invention discloses an online-manageable air-cooled screw chiller and a management system, including a box body, the online-manageable air-cooled screw chiller and a management system, built-in pressure and temperature and humidity sensors to detect the operating environment of components, and data collection The detector collects the detection data in time, and the PLC controller integrates and analyzes the post-processing. The working data can be stored locally through the memory. With the support of the wireless network, the data is transmitted to the cloud server for storage through the wireless transmitter. When the data is abnormal or the equipment fails, the near-end alarm, the PLC controller can obtain the cloud data in real time, and then manage and monitor the working conditions of all equipment remotely, and can also predict the service life and failure probability of components, and then spare parts in advance to reduce failures The maintenance time is optimized by optimizing the structure of the evaporator and condenser to ensure sufficient heat exchange, thereby speeding up the cooling process of water, and greatly shortening the time for making cold water.

Description

technical field [0001] The invention relates to the technical field of chiller equipment, in particular to an air-cooled screw chiller capable of online management and a management system. Background technique [0002] Chillers are divided into air-cooled chillers and water-cooled chillers in the industry. Chillers are divided into low-temperature chillers and normal-temperature chillers in terms of temperature control. The normal temperature is generally controlled within the range of 0 degrees to 35 degrees. The temperature control of the cryogenic machine is generally in the range of 0 degrees to minus 45 degrees. The screw chiller is named because it uses a screw compressor. Its cooling power is larger than that of the scroll chiller. It is mainly used in chemical plants, In ink printing plants, automobile manufacturing plants or central air-conditioning systems or other large-scale industrial refrigeration, large enterprises use multiple devices at the same time, and th...

[0002] Chillers are divided into air-cooled chillers and water-cooled chillers in the industry. Chillers are divided into low-temperature chillers and normal-temperature chillers in terms of temperature control. The normal temperature is generally controlled within the range of 0 degrees to 35 degrees. The temperature control of the cryogenic machine is generally in the range of 0 degrees to minus 45 degrees. The screw chiller is named because it uses a screw compressor. Its cooling power is larger than that of the scroll chiller. It is mainly used in chemical plants, In ink printing plants, automobile manufacturing plants or central air-conditioning systems or other large-scale industrial refrigeration, large enterprises use multiple devices at the same time, and the existing screw chillers are managed separately, and there is a lack of unified and effective joint management in their maintenance or work, resulting in Its working status and fault conditions cannot be monitored remotely, which will affect the overall work efficiency and work progress. This is especially important for large enterprises that use multiple chillers, and it will also cause inconvenience to the manufacturer's after-sales maintenance work, and the evaporator and The heat exchange efficiency of the condenser is low, resulting in poor cooling effect, insufficient heat exchange between water and evaporator, resulting in poor water cooling effect, low heat dissipation efficiency of the device body, which seriously affects the working status of internal equipment, so it can solve such problems The realization of an air-cooled screw chiller and management system that can be managed online is imperative
