Description

technical field [0001] The invention relates to the field of construction equipment measurement, in particular to a remote measurement device and system for a detachable central air conditioner. Background technique [0002] In recent years, with the continuous emphasis on energy conservation and emission reduction, energy-saving renovation of existing buildings has become an inevitable trend. The central air-conditioning system accounts for the vast majority of building energy consumption, so the energy-saving renovation of the central air-conditioning system is the most effective way for building energy-saving renovation. The energy consumption diagnosis of the central air-conditioning system is a necessary prerequisite for its energy-saving transformation. To diagnose the energy consumption of the air conditioning system, it is necessary to measure the chilled water / cooling water flow rate during system operation, the power of the chiller and chilled water / cooling water ...

AI Technical Summary

Problems solved by technology

Due to the large number of measurement parameters, inconsistent test instruments, and the inability to automatically record and transmit data, this traditional measurement method leads to long test time, heavy workload, and limited data volume, making it impossible to quickly and comprehensively grasp system operation information

And in the case of limited manpower, it is impossible to measure these parameters simultaneously, which leads to the inability to obtain the dynamic performance of the air conditioning system

In addition, the traditional measurement method requires testers to stay on site, so it is impossible to perform long-term measurement on site, and it is impossible to monitor the system for a long time

In addition, since all measurement data requires post-processing analysis, performance evaluations such as cooling capacity, chiller COP, water pump efficiency, chilled water distribution coefficient, cooling water distribution coefficient, and cooling station EER cannot be intuitively obtained during the test parameter
