System and method for centralized steam cleaning

A centralized steam cleaning system comprising:

• a pipe network distributed across one or more areas of a building, wherein the pipe network comprises a vacuum pipeline and a water pipeline that extend alongside each other;
• and
• a plurality of access ports connected to the pipe network, wherein each access port comprises an outlet of the water pipeline and an outlet of the vacuum pipeline,
• wherein the water pipeline is configured to allow a water steam to flow therethrough, wherein the vacuum pipeline is configured to allow air under negative pressure to flow therethrough,
• wherein the plurality of access ports comprises one or more pass-through access ports, wherein each pass-through access port comprises a housing enclosing the outlet of the water pipeline and the outlet of the vacuum pipeline, and
• wherein the water pipeline and the vacuum pipeline extend through the housing of each pass-through access port.

A method comprising:

• causing water steam to flow through a water pipeline of a pipe network distributed across one or more areas of a building;
• causing air under negative pressure to flow through a vacuum pipeline of the pipe network, wherein the vacuum pipeline and the water pipeline extend alongside each other;
• enabling flow of the water steam through an outlet of the water pipeline at an access port connected to the pipe network;
• enabling application of the air under negative pressure through an outlet of the vacuum pipeline at the access port;
• releasing the water steam from the outlet of the water pipeline toward a target area;
• and
• applying the air under negative pressure from the outlet of the vacuum pipeline to the target area,
• wherein the access port comprises a housing enclosing the outlet of the water pipeline and the outlet of the vacuum pipeline.
