AI Technical Summary

Benefits of technology

The present invention provides an access port for HVACR air duct systems that can be easily attached to an air duct or other equipment of an HVACR system and used to periodically access, measure, and test the air flow properties of the system without the need to drill new holes each time the unit is serviced. The access port includes a mounting flange for attachment to the air duct, an access port with an opening for inserting a probe, and a cap for sealing the access port. This invention allows for quick, easy, and accurate measurement and testing of air properties within functioning air ducts and other equipment of HVACR systems.

Problems solved by technology

The next service technician typically does not see (and / or does not even search for) the covered hole, for such reasons as the holes are typically drilled in unlit and enclosed spaces, the aluminum-colored duct tape is difficult to find, the mastic covering the previous hole requires that a new hole be drilled, and / or the previous holes may be in inconspicuous locations.
Further, if the previous holes are not properly sealed, then there may be leakage through the air ducts which can harm the HVACR system.

Embodiment Construction

[0017]As used herein, the terms “HVACR systems” or “HVACR air duct systems” means air duct systems and equipment relating to industrial, commercial and / or residential heating, ventilation, air conditioning and / or refrigeration (HVACR) systems, including furnace systems. The present invention remedies the scenario in which multiple holes are drilled into the air ducts or other equipment of an HVACR system over time, and provides a re-usable and re-sealable access port for attachment to air ducts, vents, furnaces or other equipment of HVACR systems. Temperature probes, pressure sensors / probes and the like can be inserted through the access port any time a service technician is required to do so.

[0018]With reference to FIGS. 1-3, the present invention is an apparatus 10 for attachment to an air duct or other equipment of an HVACR system which includes a mounting flange 12 having an access port 16 for insertion of a probe therethrough. A circular access port 16 having an opening 18 is t...

Abstract

An apparatus for use with residential, commercial and industrial HVACR air duct systems and equipment, providing a means to quickly, easily and accurately measure and / or test air properties within functioning HVACR systems without having to drill a hole into the duct or equipment wall(s) each time the unit is serviced. The apparatus generally includes a mounting flange for attachment to an air duct or other equipment of an HVACR system and an access port including an opening for insertion of a probe therethrough for taking measurements; a cap is also typically included for sealing the access port during periods of non-use. The opening of the access port is centered and placed over a small hole created by a service technician in the wall of the air duct.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to measuring and testing air properties within air ducts and equipment of residential and commercial HVACR systems, and more particularly to a re-sealable access port for use in inserting a probe therethrough.BACKGROUND OF THE INVENTION[0002]It is often desirable for a technician to insert a temperature probe and / or a pressure sensor into an air duct or furnace while testing an industrial, commercial or residential Heating, Ventilation, Air Conditioning and / or Refrigeration (HVACR) system, in order to monitor the temperature and / or air flow quality of the air in the ducts. Previous methods of access to air ducts or other equipment of an HVACR system involve a technician drilling one or more holes through the walls of the air ducts as needed, inserting a probe such as a temperature or pressure / flow measuring sensor, followed by removal of the probe and “closing” the hole with aluminum foil, mastic and / or a heavy duet...
