Energy Saving the "Record" System

A study is presently being conducted at the French Telecommunications Research Centre (CNET) in order to optimize the power consumption of air conditioning equipment in time-division exchanges. It is conducted within the frame of an "Energy Saving" campaign started by the French Administration. The so-called RECORD system (research for continuous optimal conditions of the air-conditioning system) was developed. This system enables the following functions to be performed: - acceptance and maintenance operations in air conditioning systems, - checking of power consumption, - evaluation of possible energy savings, provided the regulation instructions are modified within limits giving the same quality of service and reliability of the exchange.
