International Classification:

F24D 19/10
G05D 23/275
B60H 1/00
B60H 1/03

US Classification:

236 1B, 237 2 A

Abstract:

A system and method to control environmental parameters of pre-defined zones within an environment using an electronic controller are disclosed. The system includes an electronic controller which enables a weighting value to be assigned to each zone within the environment. The electronic controller also detects any zone service calls from sensor devices associated with each of the zones and determines a cumulative weighting value in response to the detected zone service calls. The electronic controller selects a staging combination from at least two possible staging combinations in response to at least the cumulative zone weighting value.

US Classification:

236 1B, 236 493, 165217

Abstract:

A system and method to control environmental parameters of pre-defined zones within an environment using an electronic controller are disclosed. The system includes a non-proprietary electronic controller which enables a weighting value to be assigned to each zone within the environment. The electronic controller also detects any zone service calls from sensor devices associated with each of the zones and determines a cumulative weighting value in response to the detected zone service calls. The electronic controller selects an equipment staging combination from at least two possible equipment staging combinations in response to thermal capacity, and an air handler stage is selected in response to at least the cumulative zone weighting value.

Assignee:

Arzel Zoning Technology, Inc. - Cleveland OH

International Classification:

F25B 25/00

US Classification:

62260, 62332

Abstract:

A system and method to control environmental parameters of pre-defined zones within an environment using an electronic controller. An electronic controller monitors a loop temperature of a loop field of a geo-thermal heat pump as detected by a temperature sensor connected to the loop field. The electronic controller selects a staging combination of the geo-thermal heat pump and an auxiliary HVAC equipment based on at least the loop temperature. The electronic controller activates the selected staging combination, to modify at least a portion of the environmental parameters, using non-proprietary activating signals provided by the electronic controller.

International Classification:

F24F 11/00

US Classification:

454256000

Abstract:

A SDHV damper assembly and methods to assemble and install the SDHV damper assembly are disclosed. The SDHV damper assembly includes a first damper housing half comprising a substantially cylindrical tube having a first open end and a second open end. The SDHV damper assembly further includes a second damper housing half comprising a substantially cylindrical tube having a first open end and a second open end. The first open end of the second damper housing half is joined to the first open end of the first damper housing half to form an assembled damper housing. A substantially elliptical damper blade is pivotally mounted within the assembled damper housing along a minor axis of the damper blade. An actuator member is pivotally connected to a first side of the damper blade near a first end of the actuator member. The actuator member extends through an opening in the assembled damper housing and connects to a driving element of a damper actuator at a second end of the actuator member.

Abstract:

A SDHV damper assembly and methods to assemble and install the SDHV damper assembly are disclosed. The SDHV damper assembly includes a first damper housing half comprising a substantially cylindrical tube having a first open end and a second open end. The SDHV damper assembly further includes a second damper housing half comprising a substantially cylindrical tube having a first open end and a second open end. The first open end of the second damper housing half is joined to the first open end of the first damper housing half to form an assembled damper housing. A recess is formed in the damper housing either diametrically or longitudinally. The expandable damper member is received within the recess and expands to restrict flow in the damper housing and retracts to allow laminar flow through the damper housing.
