1. In a cleanroom unit comprising an enclosed space supplied with conditioned air characterized by its temperature, humidity and differential pressure through electrically powered HEPA filter fan units and illuminated by electric lights, a system for managing cleanroom resources by a user comprising:
a. means for monitoring and recording said cleanroom air characteristics comprising:
i. an electronic temperature sensor located within said cleanroom,ii. an electronic humidity sensor located within said cleanroom,iii. an electronic room differential pressure sensor located within said cleanroom, andiv. a personal computer having a graphical user interface executing a cleanroom control system program, said personal computer receiving electronic signals from said electronic temperature, humidity and pressure sensors and providing electronic control signals for said HEPA filter fan units and said electric lights; b. means for setting predetermined limits within said cleanroom control system program executing on said personal computer that establish an acceptable range of electronic signals from said temperature, humidity and pressure sensors; c. means for notifying said user of alarm situations when said cleanroom air characteristic sensor signals fall outside said predetermined limits through the graphical user interface of the cleanroom system control program executing on said personal computer; d. means for setting predetermined schedules for application of said control signals for said HEPA filter fan units and said electric lights; and e. means for reducing cleanroom energy usage by controlling the electrical power applied to said HEPA filter fan units (FFUs) and said electric lights in response to said control signals provided by the cleanroom system control program executing on said personal computer. |
