Problems solved by technology

However, for the modular air source heat pump unit group, the image recognition frost control method is affected by cost factors, and it is difficult to use it on multiple units at the same time, which restricts the popularization and application of the image recognition frost control method, resulting in the removal of the modular air source heat pump unit group. The frost efficiency is low, and the energy efficiency of operation is attenuated

Abstract

The invention discloses a modular air source heat pump unit group defrosting control system and method based on image recognition frost measuring, and belongs to the field of air source heat pump defrosting control. For a modular air source heat pump heating unit group in winter, an effective image recognizing frost measuring technology is adopted in a selected unit for defrosting control, a localarea network and a big data analysis method are adopted, defrosting operation of a whole unit group is controlled in a point to area manner, the application cost of an image recognizing frost controltechnology is effectively reduced, the defrosting efficiency of each unit is improved, and efficient application of the air source heat pump unit group is ensured.

Description

technical field [0001] The invention relates to a novel group control defrosting system and method, in particular to a modularized air source heat pump group defrosting control system and method based on image recognition and frost measurement technology, belonging to the field of air source heat pump defrosting control. Background technique [0002] As an energy-saving and efficient renewable energy utilization technology, air source heat pump has been widely used in most areas of our country and has been widely promoted in building space heating. At present, for commercial buildings, industrial plants and other large public buildings, modular air source heat pump units are often used as the system heat source for central heating. When the air source heat pump operates in winter, frost is the key problem restricting its efficient and stable operation. [0003] The existence and growth of the frost layer increases the heat transfer resistance of the outdoor heat exchanger o...
