Key points for supervision and control of general and medical integrated air conditioning systems with heat recovery
A universal central air conditioning system that integrates medical air conditioning systems is prone to problems with construction quality,unsatisfactory debugging results,and operational failures due to cross pipe network,mode switching,and complex control logic.Especially with the addition of condensation heat recovery,the system becomes more complex.From the perspective of supervision,the article systematically and comprehensively sorts out the main problems in the construction,installation,commissioning,and operation maintenance of medical air conditioning systems.By changing the control of return water to control of outlet water,the water temperature is effectively stabilized;by adding buffer water storage tanks,the problem of water flow fluctuations has been effectively solved.In addition to analyzing the logic of mode switching,the control logic of components such as plate heat exchangers is also analyzed.The innovation of the article lies in using BA(air conditioning group control system)to manufacture the most unfavorable working conditions,debugging the differential pressure bypass valve,and effectively ensuring the stability of system operation.The parameter setting and adjustment of the mode during operation and maintenance can not only stabilize the system but also reduce waste.At the same time,the parameter setting problem of BA has been analyzed.
