（8）：In above process, when temperature has reached the temperature of setting in the board of adjusting, compressor（2）It will close,
When temperature is higher than the temperature set in board, compressor（2）Then work on；
（9）：Due to the PET circulatory systems（6）The environment temperature applied is relatively low, thus passes through condenser（4）Air afterwards still may be used
To continue to power supply box（10）It radiates, to ensure power supply box（10）It will not lead to hyperthermia and superheating because of persistent fever,
It ensure that the normal operation of whole equipment.
3. a kind of working method of medical treatment PET-CT direct-current air cooling air-conditionings according to claim 2, it is characterised in that：It is described
Evaporating fan（8）Work-based logic it is as follows：
Return air temperature TRA:For evaporating fan（8）Suction comes from the PET circulatory systems（6）The temperature of apoplexy；
Leaving air temp TCO：To pass through evaporator（3）The temperature of wind after cooling；
When 3 DEG C of TRA-TCO ＞, evaporating fan（8）Increase rotary speed working IP13 be 100%, make its temperature stablize 2.5 DEG C >=
TRA-TCO >=1.5 DEG C, evaporating fan after stablizing（8）It is 70% that rotating speed, which is reworked in IP12,；
When 1 DEG C of TRA-TCO ＜, evaporating fan（8）Reduce rotary speed working IP14 be 40%, make its temperature stablize 2.5 DEG C >=
TRA-TCO >=1.5 DEG C, evaporating fan after stablizing（8）It is 70% that rotating speed, which is reworked in IP12,.
4. a kind of working method of medical treatment PET-CT direct-current air cooling air-conditionings according to claim 2, it is characterised in that：It is described
Condenser fan（9）Work-based logic it is as follows：
When 23 DEG C of environment temperature ＜, condenser fan（9）It is 40% to be operated in EP11；
When 28 DEG C of environment temperature ＞, condenser fan（9）It is 100% to be operated in EP13；
If 28 DEG C >=environment temperature >=23 DEG C, condenser fan（9）It is 70% to be operated in EP12.
