Air cooling screw water chilling machine capable of being managed online and management system

Abstract

The invention discloses an air cooling screw water chilling machine capable of being managed online and a management system. The machine comprises a box body. According to the air cooling screw waterchilling machine capable of being managed online and the management system, a built-in pressure sensor and a temperature and humidity sensor are used for detecting the operation environment of parts,a data acquisition device is used for collecting the detection data in time, the data is integrated and analyzed by a PLC and then is processed, the working data can be stored locally through a memorizer, under the support of a wireless network, the data is transmitted to a cloud server for storage through a wireless transmitter, an alarm is arranged to give an alarm when the data is abnormal or the equipment breaks down, the PLC can obtain cloud data in real time so as to remote manage and monitor the working conditions of all equipment, the service life and the fault occurrence probability of the assembly can be estimated so that the spare part can be prepared in advance, the fault maintenance time is shortened, the structure of an evaporator and a condenser is optimized, sufficient heatexchange is guaranteed, the refrigeration process of water is accelerated, and the cold water preparation time is greatly shortened.

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
