A method for obtaining a desired atmosphere within an interior space during an initial startup phase of a CAS is provided. The method includes a controller starting the CAS while keeping the air compressor OFF. The method also includes the controller calculating an atmosphere change rate while the air compressor OFF, and determining whether the interior space can reach a desired atmosphere set point with the air compressor OFF based on the atmosphere change rate. Further, the method includes the controller maintaining the air compressor OFF until the interior space reaches the desired atmosphere set point when the controller determines that the interior space can reach the desired atmosphere set point with the air compressor OFF, and switching the air compressor ON when the controller determines that the interior space cannot reach the desired atmosphere set point with the air compressor OFF.

Controlled atmosphere system and method for controlling the same

Air filtration systems and methods for HVAC units in transport compartments are provided. The air filtration systems and methods described herein use electrostatic forces to capture airborne particles and include a modular design so as to be configured to the space requirements of the transport compartment and reduce air flow resistance. The air filtration system includes one or more modular filtration units. Each of the modular filtration units includes a pre-filter section, an ionizing section and a collecting section.

Air filtration system and method for a HVAC unit in a transport compartment

A mass transit vehicle includes a frame and a cabin mounted to the frame. The cabin includes a roof and a passenger zone defining a passenger zone length. An air cleaning unit includes an air cleaner housing mounted to the roof. The air cleaning unit is operable to draw in air through an inlet, through an air cleaning device, and discharge a flow of cleaned air out of an outlet. An air conditioning unit includes an air conditioner housing separate from the air cleaner housing. The air conditioning unit is operable to draw in air through an inlet, through an air conditioning device, and discharge a flow of conditioned air out of an outlet. The outlet of the air conditioning device is in communication with a duct system to direct the flow of conditioned air to the cabin substantially evenly along the passenger zone length.

Mobile air cleaning unit and distribution system

A mass transit vehicle including a cabin mounted to a frame and including a roof and a passenger zone defining a passenger zone length, an air cleaning unit including an air cleaner housing mounted to the roof, an air cleaning device disposed within the housing, an inlet upstream of the air cleaning device, and an outlet downstream of the air cleaning device, and a duct system disposed within the cabin and extending substantially along the passenger zone length. The air cleaning unit is operable to draw in air through the inlet, through the air cleaning device, and discharge a flow of cleaned air out of the outlet, and the duct system is in fluid communication with the outlet and operable to receive the flow of cleaned air from the outlet and direct the flow of cleaned air to the cabin substantially evenly along the passenger zone length.
