Appl. No.:

8/494688

Inventors:

Robert W. Ray - Houston TX

International Classification:

F25B 1300

US Classification:

62160

Abstract:

A thermal zone demand controlled dual cascade arranged heat pump system and system controller for building spaces, having first and second heat pumps and having an air circulation system for circulating air to and from said thermal zones and including a conditioned air chamber having first and second heat exchange refrigerant coils being connected in refrigerant circulating relation respectively with the heat pumps. A plurality of thermal zone blowers conduct conditioned air, heated or cooled, from the conditioned air chamber to respective thermal zones of the building space. Electronic controller circuitry of the system is coupled for thermal demand control of the heat pumps and the thermal zone blowers for operation of the first heat pump to accommodate a predetermined range of thermal load and for operation of the second heat pump along with the first heat pump to accommodate a greater thermal load. The controller circuitry also controls selective operation of the thermal zone blowers as well as operation of the thermal zone blowers at low blower speed or high blower speed responsive to sensed conditions of thermal load. The electronic controller circuitry further provides for selective reversal of dual heat pump operation to compensate for unequal operational wear of the heat pump units.

International Classification:

G06F 11/30

Abstract:

In some examples, a non-transitory computer-readable medium stores machine-readable instructions, which, when executed by a processor, cause the processor to: identify an event of a computing device from operational data of the computing device; evaluate the event to determine if the event is a non-routine event; and store the event to a timeline if the event is a non-routine event, where the timeline includes an incident of the computing device.
