AIR CONDITIONING/WATER SUPPLY AND DRAINAGE WORKS

9.1

Air Conditioning

(1) Air conditioning system
Refer to the calorific values and environmental requirements of each room given in section 4
and install an air conditioning system that satisfies the given environmental requirements.
Insure appropriate air flow in the rooms so that temperature distribution is uniform.
Take extreme care with air conditioning in the scanning room. Temperature fluctuation in this
room must be within the range given in the specification. The temperature setting need not
be constant throughout year. It is important to have the same temperature when calibration
data is acquired as when examinations are performed. It is recommended, however, that the
temperature be maintained at approximately 26° for patient comfort.
The temperature in the scanning room should be within the tolerance 1.5 hours before the
first examination every morning. When the door is opened, for example, to bring the patient
in or out, the temperature can be outside the tolerance for a short time (approximately 3
minutes). The appropriate temperature, however, should be restored until scanning of the
next patient is started.
In addition, since air intake to the gantry is performed at a position near the floor surface,
attention must be paid to prevent the temperature of the floor surface from becoming
excessively high. (Is there a boiler room downstairs?)

Temperature conditions in the scanning room
1. In general, the scanning room must be provided with an
independent air conditioning system.
Even if the room is maintained within the permissible
temperature range, gradual temperature shifts (for example, a
slow increase in room temperature from morning to evening)
may adversely affect system performance. Therefore, the room
temperature must be kept under constant control (within ±2°C) as
shown in the above figure.
2. The air conditioning system in the scanning room must be
installed so that the CT system is not exposed to direct airflow.
Failure to do so may cause the temperature inside the CT system
to fluctuate, possibly affecting the displayed images adversely.
