Publication number: 20100251742Abstract: An HVAC&R system is disclosed that utilizes energy-efficient valving. The valving controls the flow of refrigerant and may be adapted for evaporator or condenser applications, on both AC systems and heat pumps (as well as chillers and other refrigeration systems). The valving may provide simultaneous and individualized control of flow through individual coils or groups of coils for improved control of evaporation, condensation, defrosting and so forth. In some configurations a common sensor may be shared between individual coils or groups of coils and may provide sensed parameters to control circuitry for controlling the valving. Other configurations may include bypass valving to direct fluid around the flow control valving. In yet other configurations, a valve may be used to bypass tapped vapor around a heat exchanger functioning as an evaporator.Type: ApplicationFiled: May 14, 2010Publication date: October 7, 2010Applicant: Johnson Controls Technology CompanyInventors: Jeffrey Lee Tucker, Jeremiah Marshall Horn, Jeffrey Norris Nichols, Thomas John Martin, Gregory Ralph Harrod, Kenneth E.

Patent number: 7085626Abstract: A heating control method is provided for a multi-stage heating system including a heating circuit having a compressor, a condenser and an evaporator. An auxiliary heater is provided that is selectively controlled independently of the heating circuit. During a heating cycle in which the ambient outside temperature is greater than the balance point temperature associated with the operation of the heating circuit, the auxiliary heating circuit is normally prevented from operating. However, if the heating requirements are not satisfied after a predetermined time or the compressor is non-functional or operating improperly, the auxiliary heater is enabled.Type: GrantFiled: April 15, 2004Date of Patent: August 1, 2006Assignee: York International CorporationInventors: Gregory Ralph Harrod, Jeffrey Lee Tucker
