This invention relates to a process for cooling a product in a heat exchanger, the process comprising: flowing a refrigerant through a set of first microchannels in the heat exchanger; flowing a refrigerant through a set of second microchannels in the heat exchanger, the refrigerant flowing through

This invention relates to a process for cooling a product in a heat exchanger, the process comprising: flowing a refrigerant through a set of first microchannels in the heat exchanger; flowing a refrigerant through a set of second microchannels in the heat exchanger, the refrigerant flowing through the set of second microchannels being at a lower temperature, a lower pressure or both a lower temperature and a lower pressure than the refrigerant flowing through the set of first microchannels; and flowing a product through a set of third microchannels in the heat exchanger, the product exiting the set of third microchannels having a cooler temperature than the product entering the set of third microchannels. This process is suitable for liquefying gaseous products including natural gas.

The method as set forth in claim 3, wherein Niis updated on the basis of the following equation after the address setting is performed at said step b-2): Ni=Ni-1. 5. The method as set forth in claim 4, wherein Diis updated on the basis of the following equation after the address setting is performed at said step b-2): Di=Di-F where, F is the number of indoor units captured by said outdoor unit. 6. The method as set forth in claim 4, wherein said step b-2) includes the step of setting addresses in ones of said indoor units corresponding to ones of said production numbers whose first digit values are the same as any one of said specific numbers, and then setting addresses in ones of said indoor units corresponding to ones of said production numbers whose first digit values of Ni≠1are the same as a different one of said specific numbers. 7. An air conditioning system comprising: a plurality of indoor units each adapted to suck indoor air, perform a heat exchange operation for the sucked indoor air with a heat exchange medium and discharge the heat-exchanged air, each of said indoor units including a production number storage area defined in a memory which is installed to prevent a corresponding one of said indoor units from being subject to a data loss when a power failure occurs, said production number storage area storing information about a unique production number assigned to said corresponding indoor unit in a manufacturing process thereof; and an outdoor unit connected in common to said plurality of indoor units and adapted to perform a heat exchange operation for the heat exchange medium with external air, said outdoor unit recognizing first digit values of said production numbers stored in said indoor units, recognizing the remaining digit values of ones of said production numbers whose first digit values are the same, sequentially setting addresses in ones of said indoor units corresponding to said production numbers having the same first digit values on the basis of the recognized first and remaining digit values, and then setting addresses in ones of said indoor units corresponding to ones of said production numbers whose first digit values are not the same, in the same manner as that performed with respect to said indoor units corresponding to said production numbers having the same first digit values. 8. The air conditioning system as set forth in claim 7, wherein said outdoor unit includes: an outdoor unit automatic address setter for recognizing said production numbers of said indoor units and automatically setting the addresses in said indoor units on the basis of the recognized production numbers; an outdoor unit data converter for converting data transmitted and received between said outdoor unit and said indoor units into formats appropriate to standards of a communication line and said outdoor unit; and an outdoor unit communication circuit for transmitting output data from said outdoor unit data converter to said indoor units and for receiving data transmitted from said indoor units and transferring the received data to said outdoor unit data converter; and wherein each of said indoor units includes: an indoor unit automatic address setter for transmitting said production number information stored in said production number storage area to said outdoor unit automatic address setter; an address storage area for storing a corresponding one of said addresses set by said outdoor unit automatic address setter; an indoor unit data converter for converting data transmitted and received between said corresponding indoor unit and said outdoor unit into formats appropriate to the standard of said comm
