Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1-3, a two refrigerating system structures of passenger train overhead air conditioner, two refrigerating system structures include condenser 1, the left side of condenser 1 is equipped with first refrigerating system 2, the right side of condenser 1 is equipped with second refrigerating system 3, first refrigerating system includes first compressor 21, first expansion valve 22, first evaporimeter 23, second refrigerating system 3 includes second compressor 31, second expansion valve 32, second evaporimeter 33.
The first liquid outlet pipe 11 on the left side of the condenser 1 is connected with a first expansion valve 22, the first expansion valve 22 is connected with a first evaporator 23, the first evaporator 23 is connected with a first compressor 21, and the first compressor 21 is connected with a first air inlet pipe 12 on the left side of the condenser 1.
The second liquid outlet pipe 13 on the right side of the condenser 1 is connected with a second expansion valve 32, the second expansion valve 32 is connected with a second evaporator 33, the second evaporator 33 is connected with a second compressor 31, and the second compressor 31 is connected with a second air inlet pipe 14 on the left side of the condenser 1.
The double systems share one condenser 1, two completely independent refrigerant flow channels are formed through the arrangement of pipelines inside the condenser 1, and other refrigeration elements of each system are respectively connected in the left direction and the right direction, so that the air conditioner is more compact in structure, excessive installation structures are reduced, the effective heat exchange area can be increased in the space with the same structure size, and the material cost of the system is reduced.
Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
