PROCESS OF CONTROL OF THE SPEED OF THE COMPRESSOR AND THE MOTOR OF AN AIR CONDITIONING SYSTEM AND PERFECTED SYSTEM OF AIR CONDITIONING OF THE TYPE PRESENTING INDIVIDUAL ZONE THERMOSTATS AND VARIABLE SPEED FAN FOR AIR CIRCULATION TO INDIVIDUAL ZONES

摘要

Provision is made in a multiple zone air conditioning system for varying the speed of the compressor to match the load thereon. The differences between the actual temperatures and the set points in the individual zones are monitored and the largest of these differences is periodically selected and applied to a transfer function to obtain a new speed at which the compressor is run. At the same time, the individual dampers within the zones are modulated in response to their respective sensed temperature differences. Provision is also made to vary the speed of the indoor fan in a similar manner.
