AI Technical Summary
Technical Problem
In existing air conditioning water systems, the utilization rate of standby pumps is low, resulting in resource waste, and the pumps often operate outside their efficient operating point when put into use.
Method used
Design a pipeline structure that, by setting up backup pipelines and backup pumps in parallel with all main pipelines, and extending pipelines, uses pressure sensors and flow meters to monitor water pressure and flow, and automatically or manually controls valve opening to realize the replacement or boosting function of backup pump sets.
Benefits of technology
It effectively reduces equipment costs, ensures the normal operation of the air conditioning water system in case of malfunction or insufficient water flow, and improves system stability and efficiency.

Abstract
The application discloses a pipeline structure and an air conditioner, which comprise: a plurality of main pipes, a water pump arranged on each main pipe, a standby pipe connected with all the main pipes through standby branch pipes and connected with the water pump on each main pipe in parallel, a standby water pump arranged on the standby pipe, a main pipe valve arranged on the main pipe and located on one side or both sides of the water pump, and a standby valve arranged on the standby pipe and located on one side or both sides of the standby water pump. The pipeline structure provided by the application can use the standby pump group on the standby pipe to maintain the normal operation of the air conditioner water system when the water pump on the freezing side or the cooling side fails or the water flow is insufficient, so that the equipment cost is effectively reduced. Meanwhile, the added range pipe can increase the pump group lift by using the standby water pump to increase the pressure of the main pipe when the water pressure of the main pipe is insufficient.
