Application of assembly high efficient refrigerating machine room to urban rail transit underground station based on BIM

Reviews the present situation of air conditioning and cooling machine rooms in the underground station of urban rail transit, and analyses the main problems and their causes. Combined with a practical engineering project, expounds how to realize the closed loop management of the design, construction, commissioning and operation of the air conditioning and refrigerating machine room by BIM technology, and provides the conventional process and key points of the assembly high efficient refrigerating machine room construction based on BIM, recommending a practical solution for the energy efficient operation of the air conditioning and refrigerating machine room system of urban rail transit.
