20080271874 | THERMAL ENERGY EXCHANGER - A thermal energy exchanger assembly ( | 11-06-2008 |
20080283217 | Stackable energy transfer core spacer - A stackable spacer element for use in a energy recovery core formed by stacking a plurality of relatively thin energy transfer media (e.g. sheets, panels, or plates (un-perforated exchanger sheets) so as to define a plurality of stacked energy transfer stages providing air passages for two separate air flows. | 11-20-2008 |
20090056909 | HEAT EXCHANGER HAVING AN INTERNAL BYPASS - The present invention provides an exhaust recirculation cooler for transferring heat between engine exhaust and a coolant. The cooler can include a housing having a first end and a second end spaced from the first end, a heat transfer region extending through the housing and including a plurality of tubes positioned along a flow path for the coolant, and an internal bypass extending through the housing between the first end and the second end adjacent to the heat transfer region. Together, at least one of the plurality of tubes and the internal bypass provide an exhaust flow path through the cooler. | 03-05-2009 |
20090133851 | HEAT RECOVERY VENTILATOR WITH DEFROST - A defrost system for a heat recovery ventilator/energy recovery ventilator (HRV/ERV), uses the interior space supply air of an integrated fan coil for defrosting a HRV/ERV core without creating negative pressure in the interior space, which wastes energy, without need of an external fifth port from which to draw defrost air from the interior space, which increases costs, and without re-circulating exhaust air into the interior space. During the defrost cycle, automatically controlled dampers close off the fresh air and exhaust air inputs, and exhaust output, and circulate supply air through the heat exchange core and into to the living space. | 05-28-2009 |
20100288467 | EXPLOSION-PROOF ENCLOSURES WITH ACTIVE THERMAL MANAGEMENT BY HEAT EXCHANGE - Enclosures for use in hazardous areas include heat exchangers for active thermal management. The enclosures are coupled to a device having heat transfer capabilities. Equipment within the enclosures produces heat within the enclosure. The heat exchanger removes heat produced from the equipment and manages the internal temperature of the enclosures to a level suitable for hazardous locations. The enclosures can be actively cooled or heated using the device. | 11-18-2010 |
20130056174 | VENTILATION APPARATUS - A ventilation apparatus is provided. The ventilation apparatus may include a base, frames positioned on the base, a rear panel positioned behind the frames and having an interior air discharge port and exterior air suction port formed therein, a top cover positioned on top of the frame and having exterior air discharge port formed therein, and a front panel positioned in front of the frames and having an interior air discharge port formed therein. Heat exchangers disposed in the frames may include interior and exterior air passages. An exhaust fan and air supply fans provide for air flow through the apparatus, guide by the frames. Use of the frames to guide air flow simplify structures and may enhance efficiency by simplifying the passages of the exterior and interior air through the apparatus. | 03-07-2013 |
20130126123 | ARCHITECTURAL HEAT AND MOISTURE EXCHANGE - An architectural heat and moisture exchanger. The exchanger defines an interior channel which is divided into a plurality of sub-channels by a membrane configured to allow passage of water vapor and to prevent substantial passage of air. In some embodiments, the exchanger includes an opaque housing configured to form a portion of a building enclosure, such as an exterior wall, an interior wall, a roof, a floor, or a foundation. | 05-23-2013 |
20140041830 | HEAT AND MOISTURE TRANSFER APPARATUS INTEGRATED INTO AN EXTERIOR PARTITION - Systems, apparatus and methods that may be used to integrate a heat and moisture exchange system with the heating, ventilation and air conditioning system of a building or other enclosed space, without requiring installation within the walls or other structural portions of the building. | 02-13-2014 |
20140326432 | COUNTER-FLOW ENERGY RECOVERY VENTILATOR (ERV) CORE - A heat and humidity exchanger has example application in exchanging heat and water vapour between fresh air entering a building and air being vented from the building. The heat and humidity exchanger has a self-supporting core formed from layered sheets ( | 11-06-2014 |
20150338122 | SUMMER BYPASS FOR HEAT RECOVERY UNIT - There is provided a heat recovery ventilation unit comprising a first air flow path and a second air flow path and a heat exchanger in which the first air flow path is in heat exchange contact with the second air flow path; the unit further comprising an air flow path selector in the first air flow path which is arranged to select between the first air flow path and a third air flow path which bypasses the heat exchanger; wherein the air flow path selector is located between an inlet filter of the first air flow path and the heat exchanger. Providing the bypass selector between the filter and the heat exchanger, air is always filtered, even in the bypass mode, thus reducing particulate matter drawn into the building during bypass operation. | 11-26-2015 |
20160084518 | Air Exchange Device Capable of Adjusting Temperature Difference - An air exchange device capable of adjusting temperature difference includes: a housing, a partition, a fan, a control module and a temperature difference adjusting module. The partition is mounted in the housing and divides a room inside the housing into a first air-guiding space and a second air-guiding space. The fan is mounted in the housing. The control module electrically connects with the fan. The temperature difference adjusting module includes a temperature regulator electrically connected to the control module. With the temperature difference adjusting module, an internal space is maintained as an environment with comfortable temperature in the air exchange process. | 03-24-2016 |
