Abstract
An isolated work space is created within a confined area used as an airflow plenum to inhibit the spread of debris and/or contamination. For example, a work area can be formed in an under-floor space of a datacenter. Forming the work area includes erecting an airflow barrier to surround a work area portion of the under-floor space, forming a lower-perimeter seal to seal a bottom edge of the airflow barrier, forming an upper-perimeter seal to seal a top edge of the airflow barrier, operatively connecting a vacuum source with the work area portion, and operating the vacuum source to reduce the air pressure within the work area portion relative to the remaining portion of the under-floor space.
Claims17
A method of forming a work area in an under-floor space of a datacenter, the under-floor space being disposed between a floor surface and a raised floor and used as a plenum to supply cooling air to datacenter components located above the raised floor, the work area being configured to inhibit a first airflow from the work area to the datacenter components, the method comprising:
- erecting an airtight airflow barrier to surround a work area portion of the under-floor space to isolate the work area portion from a remaining portion of the under-floor space, the airtight airflow barrier extending from adjacent to the floor surface to adjacent to the raised floor so as to inhibit a second airflow from the work area portion into the remaining portion of the under-floor space;
- forming a lower-perimeter seal between a bottom edge of the airtight airflow barrier and the floor surface, the lower-perimeter seal extending around a lower perimeter of the airtight airflow barrier;
- forming an upper-perimeter seal between a top edge of the airtight airflow barrier and the raised floor, the upper-perimeter seal extending around an upper perimeter of the airtight airflow barrier;
- inflating a plurality of inflatable column segments of the airtight airflow barrier to separate the lower-perimeter seal and the upper-perimeter seal so as to hold the lower-perimeter seal in contact with the floor surface and hold the upper-perimeter seal in contact with the raised floor;
- operatively connecting a vacuum source with the work area portion;
- and
- operating the vacuum source to reduce air pressure within the work area portion relative to the remaining portion of the under-floor space.
A method of forming an isolated work area within an under-floor space of a datacenter, the method comprising:
- erecting an airtight airflow barrier to surround a work area portion of the under-floor space so as to inhibit airflow from the work area portion into a remaining portion of the under-floor space;
- and
- inflating a plurality of inflatable column segments of the airtight airflow barrier to separate a lower-perimeter seal of the airtight airflow barrier and an upper-perimeter seal of the airtight airflow barrier so as to hold the lower-perimeter seal in contact with the floor surface and hold the upper-perimeter seal in contact with the raised floor.
A method of forming a work area within a confined space used as an airflow plenum, the work area being configured to inhibit airflow from the work area, the method comprising:
- erecting an airtight airflow barrier to surround a work area portion of the confined space to isolate the work area portion from a remaining portion of the confined space, the airtight airflow barrier being configured to inhibit the airflow from the work area portion into the remaining portion of the confined space;
- inflating a plurality of inflatable column segments of the airtight airflow barrier to separate a lower-perimeter seal of the airtight airflow barrier and an upper-perimeter seal of the airtight airflow barrier so as to hold the lower-perimeter seal in contact with a floor surface and hold the upper-perimeter seal in contact with a raised floor;
- operatively connecting a vacuum source with the work area portion;
- and
- operating the vacuum source to reduce air pressure within the work area portion relative to the remaining portion of the confined space.
A prefabricated modular barrier assembly for forming a work area in an under-floor space of a datacenter, the under-floor space being disposed between a floor surface and a raised floor and used as a plenum to supply cooling air to datacenter components located above the raised floor, the work area being configured to inhibit a first airflow from the work area to the datacenter components, the barrier assembly comprising:
- one or more prefabricated airtight sections that can be passed through a rectangular opening approximately 2 feet by 2 feet, each of the one or more prefabricated airtight sections including:
- one or more coupling features configured to enable joining of the one or more prefabricated airtight sections into an erected configuration that surrounds the work area portion and inhibits a second airflow from the work area portion into the remaining portion of the under-floor space;
- a deformable lower edge seal member configured to interface with the floor surface to inhibit the second airflow from the work area portion into the remaining portion of the under-floor space;
- and
- a deformable upper edge seal member configured to interface with the raised floor to inhibit the second airflow from the work area portion into the remaining portion of the under-floor space,
- wherein the one or more prefabricated airtight sections comprise a plurality of inflatable column segments that, when inflated, separate the lower and upper edge seal members so as to hold the lower edge seal member in contact with the floor surface and hold the upper edge seal member in contact with the raised floor.
