Research on the Application of Water-cooled VRF Air Conditioning System in Subway Stations
Aiming to a series of problems such as low cold source efficiency caused by long partial load operation time of the water-cooled chiller unit in the subway station air conditioning system,high transportation energy consumption of the all air conditioning system,and large pipeline space occupation,based on the research that the actual air conditioning load in the equipment room is generally lower than the design value,this paper proposes an application plan of the water-cooled VRF air conditioning system in the subway station equipment management room,And the water-cooled VRF air conditioning system of a southern station that was put into operation was tested and compared with the conventional cold source scheme on the same line.The results show that the application of water-cooled VRF air conditioning system of equipment management rooms in subway stations has significant advantages in saving air conditioning room area,simplifying equipment area pipelines,matching load cooling,and saving operational energy consumption.
