Control method, device and system for air blower of polycrystalline silicon chilling room

Abstract

The invention discloses a controlling method, device and system for air blower of polycrystalline silicon chilling room. The method comprises the following steps of: gathering information of the environment situation in polycrystalline silicon chilling room, wherein the environment information should include at least the temperature and space of polycrystalline silicon chilling room. The operatingpower of the cooling water pump in the chilling room of the polycrystalline silicon is determined by the environment information of polycrystalline silicon chilling room based on the temperature of polycrystalline silicon to be cooled. The operating power of the air blower in the chilling room of the polycrystalline silicon is determined by the operating power of the cooling water pump, the temperature of the polycrystalline silicon to be cooled and the environment information of polycrystalline silicon chilling room. When the operation of the cooling water pump is detected, the linkage control cooling fan works according to the operation power of the determined the air blower in the polycrystalline silicon chilling room. The control method, device and system for air blower of polycrystalline silicon chilling rooms adjust the operation power of the air blower in real time according to the environment temperature in polycrystalline silicon chilling room, achieves the technical effect of reducing the energy consumption.

Description

technical field [0001] The present application relates to the technical field of silicon wafer manufacturing, and in particular to a control method, device and system for a fan in a polycrystalline silicon ingot cooling room. Background technique [0002] Polysilicon is the main raw material for manufacturing photovoltaic cells. In recent years, with the rapid development of the photovoltaic industry, the demand for polysilicon is also increasing. The fan is a key equipment in the polysilicon production process, which is distributed in many production process links of polysilicon production. Take the polysilicon ingot cooling room as an example, since the polysilicon ingot temperature is generally very high (approximately 400 degrees Celsius), the temperature in the cooling room is also high, and fans are usually used to cool down. Since the power of the fan used is generally relatively large, the power consumption of the fan becomes a big expense in the cooling process of ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing polysilicon ingot cooling room, the fan is always on, so that when the ambient temperature does not need to be cooled by the fan, a large part of the electric energy is wasted due to the operation of the fan.
