Abstract:

A dual airflow control system for an environment having a first air zone and a second air zone. The system includes a first input device operable to generate a first input signal indicative of a desired airflow to the first zone and a second input device operable to generate a second input signal indicative of a desired airflow to the second zone. First and second flow regulators are configured to regulate airflow to the first and second zones, respectively, such that the first and second regulators selectively provide the airflow to each of the first and second zones based on the first and second input signals. A single actuator is associated with the first and second flow regulators. The actuator is operable to simultaneously actuate the first and second flow regulators based on an input from the first and second input devices to allow the desired airflows to the first and the second zones.

US Classification:

62185, 62201, 62239, 236 1 B

Abstract:

An air-treatment system includes a cooling circuit, a first heat exchanger in thermal communication with the cooling circuit, and a secondary circuit in thermal communication with the first heat exchanger. The air-treatment system also includes a controller in communication with at least one of the cooling circuit, the first heat exchanger, and the secondary circuit. The controller is operable to receive at least one input indicative of a desired ambient condition, operable to receive at least one input indicative of current ambient conditions, operable to receive at least one input indicative of at least one of the cooling circuit operation and secondary circuit operation, and operable to change the operation of at least one of the cooling circuit and the secondary circuit when the current ambient condition is outside of a desired operation condition range.

US Classification:

417363, 248603, 248675

Abstract:

A mounting system is provided for supporting a weight of a compressor in a mobile application. The compressor may include a top end and a bottom end. The mounting system may include a housing having a top plate and a bottom plate, the top plate being disposed a distance above the bottom plate. A mounting bracket may be connected to the top plate and the bottom plate. An isolation assembly may be disposed on the mounting bracket and may be configured to connect to the compressor at a connecting location below the top end and above a location at or adjacent to the bottom end of the compressor. The isolation assembly is configured to support the weight of the compressor at the connecting location without the compressor being supported adjacent to its bottom end.
