Claim 5:
6. The method of designing a heat exchanger group according to claim 1,
wherein the design variable relating to the tube bundle includes:
a design variable selected from the number of tube bundles to be provided to one ACHE, the number of heat transfer tubes to be included in the tube bundle, the number of passages of each of the heat transfer tubes to be included in the tube bundle, the number of stages of the heat transfer tubes in the tube bundle, a type of arrangement intervals between the heat transfer tubes in the tube bundle, and a tube length of each of the heat transfer tubes from one end to another end of the tube bundle;

wherein the design variable relating to each of the heat transfer tubes includes:
a design variable selected from an outer diameter of each of the heat transfer tubes, a wall thickness of each of the heat transfer tubes, and an arrangement pitch of the heat transfer tubes;

wherein the design variable relating to the fan includes:
a design variable selected from the number of installed fans in one ACHE, a diameter of the fan, a fan efficiency of the fan, and a face velocity of cooling air supplied to the ACHE by the fan.
