a transferring part configured to transfer the substrate between the heating unit and the liquid processing unit;
the liquid processing method comprising:
a step of suctioning air in the clean room and taking the air into a power room having an atmosphere separated from the clean room by a partition member;
a step of controlling a temperature of the air taken in via the air suction path in the power room;
a step of supplying the air whose temperature is controlled to the liquid processing unit;
a step of suctioning the air from the air suction path and supplying the air via the air supplying path; and
a step of cleaning the air taken in from the air suction path;
wherein the air suction path and the air supplying path are formed by either an internal space of an internal pipe of a double pipe or a space between the internal pipe and an external pipe of the double pipe.
2. The liquid processing method as claimed in claim 1 further comprising:
a step of controlling moisture in the air taken in via the air suction path in the power room.
3. The liquid processing method as claimed in claim 1 ,
wherein the power room is formed under a floor of a room where the apparatus main body is provided.

one liquid processing unit is a resist coating unit configured to coat resist liquid onto the substrate; and
another liquid processing unit is a developing unit configured to supply developing liquid to the substrate and develop the resist.
5. The liquid processing method as claimed in claim 1 ,
wherein an opening for jetting the air is provided at a ceiling of the clean room; and
a step of suctioning the air in the clean room from the air suction path and taking the air in the power room is performed in a position having the same height as the apparatus main body or a position higher than the apparatus main body.
6. The liquid processing method as claimed in claim 1 further comprising:
a step of suctioning the air supplied to the liquid processing unit to the air suction path.
7. The liquid processing method as claimed in claim 1 ,
wherein the apparatus main body includes an electric unit having an electric apparatus; and
the liquid processing method further includes a step of suctioning an atmosphere of the electric unit to the air suction path.
8. The liquid processing method as claimed in claim 1 ,
wherein the apparatus main body includes a chemical unit where the chemical solution is stored; and
the liquid processing method further includes a step of suctioning an atmosphere of the chemical unit to the air suction path.
9. The liquid processing method as claimed in claim 8 , further comprising:
a step of removing a chemical solution composition contained in the air suctioned into the air suction path from the chemical unit.
