The most cost and energy effective building energy saving measure tried has been Wide Band Temperature Control and Operation with no refrigeration provided when room ambient temperatures are below 80F (27C), and with no heating provided above 65F (18C), on a year around basis. Between these limits, the building is operated in a dynamic or transient mode. In many locales this can eliminate the energy...
The development of digital telecommunications switching equipment with its lower power per Erlang of traffic and its more constant power requirement at a time of increasing energy shortage has created the need to re-consider conventional cooling practices and to examine other less conventional methods. This paper describes current telephone exchange cooling practices, the environmental requirements...
