Commissioning method and commissioning system

Abstract

The present application relates to a commissioning method and a commissioning system. The commissioning method comprises: establishing a commissioning mission and sending it to a controller of a HVAC system, the commissioning mission comprising setting at least one test work condition with respect to an object to be commissioned, instructing the HVAC system and a digital twin system corresponding to the HVAC system to respectively operate with the at least one test work condition by the controller of the HVAC system; comparing physical data generated by the HVAC system and digital data generated by the digital twin system, and based on a comparison result, diagnosing the object to be commissioned. The present application can enable fast commissioning and obtain a reliable result.

Description

FOREIGN PRIORITY[0001]This application claims priority to Chinese Patent Application No. 201810706978.8, filed Jul. 2, 2018, and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which in its entirety are herein incorporated by reference.TECHNICAL FIELD[0002]The present application relates to a commissioning method, which specifically relates to a commissioning method for a HVAC system. Further, the present application relates to a commissioning system for the HVAC system.BACKGROUND ART[0003]“HVAC” is the abbreviation for “Heating, Ventilation and Air Conditioning”. A HVAC system applied in a large space has complicated configurations, and its installation is time-consuming and strenuous. Generally, engineers require months to commission a HVAC system and to ensure a right and proper installation as well as the fulfillment of normal functions. At present, a field engineer would fabricate a commission scheme and schedule according to a design blueprint and co...

AI Technical Summary

Benefits of technology

The solution described in this patent helps to quickly commission and get a reliable result by using a digital twin model of a HVAC system. The system and the digital twin operate under the same input conditions, and the actual output from the system is compared to a theory output generated by the digital twin. This allows for automatic detection of abnormalities in the system and producing a result quickly. The solution can be used for both equipment level and system level testing.

Problems solved by technology

A HVAC system applied in a large space has complicated configurations, and its installation is time-consuming and strenuous.

Moreover, influence relationship between all component parameters is intricate, which requires a comprehensive consideration during commissioning.

Each parameter's tiny adjustment is likely to cause a large or small change in parameters of the whole system, and further affect its performance.

In this manner, a manual commissioning consumes much time.
