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.

         4 . The commissioning method of  claim 1 , further comprising sending the commissioning mission to a diagnostic engine, based on the commissioning mission, the diagnostic engine capturing the physical data and the digital data from the HVAC system and the digital twin system. 
     
     
         5 . The commissioning method of  claim 4 , wherein the physical data and the digital data comprise at least one quantitative value indicative of the state of the HVAC component and the digital component respectively in the HVAC system and the digital twin system which operate in the at least one test work condition. 
     
     
         6 . The commissioning method of  claim 5 , wherein detecting the HVAC component by a sensing component in the HVAC system to obtain the physical data, and detecting the digital component by a sensing component in the digital twin system to obtain the digital data. 
     
     
         7 . The commissioning method of  claim 4 , wherein obtaining a diagnosis result of the object to be commissioned by the diagnostic engine, the diagnosis result comprising any of the situations below and is notified by the diagnostic engine to a work condition testing unit which establishes the commissioning mission:
 1) terminating a current commissioning mission;   2) changing the object to be commissioned, and establishing a new commissioning mission;   3) changing the test work condition in the original commissioning mission.   
     
     
         8 . The commissioning method of  claim 7 , wherein computing a tolerance provided by the diagnostic engine and a bias between the physical data and the digital data to obtain the diagnosis result. 
     
     
         9 . The commissioning method of  claim 2 , wherein the HVAC component comprises any one or any combination of the following group: host, compressor, condenser, cooler, cooling tower, blower, fan, evaporator, expansion valve, chilling water system, cooling system, source of cold and heat, terminal device, and various pumps, air valve/water valve, regulating valve, air/water pipe, coil pipe and switch involved in an air process unit. 
     
     
         10 . A commissioning system for a HVAC system, the HVAC system comprising a controller, a HVAC component, an actuator associated with the HVAC component and a sensing component for detecting the HVAC component, wherein the commissioning system comprises:
 a test work condition unit configured to establish a commissioning mission and send the commissioning mission to the controller;   a digital twin system comprising a digital component, a digital actuator and a digital sensing component corresponding to the HVAC component, the actuator and the sensing component, wherein the digital twin system is corresponding to the HVAC system and receives the commissioning mission from the controller with the HVAC system; and,   a diagnostic engine configured to receive physical data from the HVAC system and digital data from the digital twin system and produce a diagnosis result based on the physical data and the digital data.   
     
     
         11 . The commissioning system of  claim 10 , wherein the test work condition unit is further configured to send the commissioning mission to the diagnostic engine, and wherein the diagnostic engine captures the physical data and the digital data based on the commissioning mission. 
     
     
         12 . The commissioning system of  claim 10 , wherein the diagnostic engine is further configured to send the diagnosis result to the test work condition unit, the diagnosis result comprising any of the situations below: 1) terminating a current commissioning mission; 2) changing the object to be commissioned, and establishing a new commissioning mission; and, 3) changing a test work condition in the original commissioning mission.
