20130087302 | DETECTING AND CORRECTING ENTHALPY WHEEL FAILURE MODES - A heating ventilation and cooling system includes an energy recovery ventilator (ERV). The ERV is configured to produce an inlet airstream and an exhaust airstream. An enthalpy wheel within the energy recovery ventilator is operable to transport heat between the inlet and exhaust airstreams. A pressure transducer is configured to determine a backpressure across the enthalpy wheel. A controller is configured to determine, in response to the backpressure, an operational characteristic of the enthalpy wheel. | 04-11-2013 |
20130090769 | METHODS OF OPERATING AN HVAC SYSTEM, AN HVAC SYSTEM AND A CONTROLLER THEREFOR EMPLOYING A SELF-CHECK SCHEME AND PREDETERMINED OPERATING PROCEDURES ASSOCIATED WITH OPERATING UNITS OF AN HVAC SYSTEM - In one aspect, a controller for an HVAC system is disclosed. In one embodiment, the controller includes: (1) an interface configured to receive feedback data from operating units of the HVAC system and transmit control data to the operating units, (2) an operation verifier configured to determine an individual operating status for each one of the operating units based on the feedback data and (3) a mode setter configured to distinctly operate each one in a predetermined operating procedure based on the determined operating status for each one. | 04-11-2013 |
20130092345 | LAYOUT FOR AN ENERGY RECOVERY VENTILATOR SYSTEM - An energy recovery ventilator unit. The unit comprises a cabinet housing a primary intake zone, a supply zone, a return zone, an exhaust zone and an enthalpy-exchange zone. The primary intake zone and the exhaust zone are both on one side of the enthalpy exchange zone. The supply zone and the return zone are both on an opposite side of the enthalpy exchange zone. The unit also comprises first and second blowers. The first blower is located in the primary intake zone and configured to push outside air into the primary intake zone and straight through the enthalpy exchange zone into the supply zone. The second blower is located in the return zone and configured to push return air into the return zone and straight through the enthalpy exchange zone into the exhaust zone. | 04-18-2013 |
20130092346 | ENERGY RECOVERY VENTILATOR UNIT WITH OFFSET AND OVERLAPPING ENTHALPY WHEELS - An energy recovery ventilator unit comprising a cabinet and a plurality of enthalpy wheels mounted in the cabinet. Major surfaces of each of the enthalpy wheels are substantially separated from each other and substantially perpendicular to a direction of primary forced-air intake into the cabinet. The major surface of one of the enthalpy wheels substantially overlaps, in the direction of primary forced-air intake, with the major surface of at least one of the other enthalpy wheels. | 04-18-2013 |
20130095744 | SENSOR MOUNTING PANEL FOR AN ENERGY RECOVERY VENTILATOR UNIT - An energy recovery ventilator unit. The unit comprises a sensor mounting panel removably coupled to an outer surface of a cabinet, wherein the sensor mounting panel is configured to hold a plurality of sensors configured to measure the atmospheric environment inside of one or more of an intake zone, a supply zone, or a return zone housed inside of the cabinet. | 04-18-2013 |
20130116951 | SYSTEM AND METHOD FOR MONITORING AND REPORTING ENERGY RECOVERY VENTILATOR POWER CONSUMPTION AND SERVICE AND MAINTENANCE NEEDS - A system for, and method of, monitoring and reporting ERV power consumption and service and maintenance needs. In one embodiment, the system includes: (1) a processor configured to carry out a plurality of monitoring and reporting functions related to ERV power consumption and service and maintenance needs based on a model, and types and locations of sensors, of the ERV, (2) a memory coupled to the processor and configured to store data gathered from the sensors and (3) a commissioning database associated with the memory and configured to contain commissioning data regarding the model of the ERV and the service and maintenance needs. | 05-09-2013 |
20130124111 | SYSTEM AND METHOD FOR MONITORING AND REPORTING ENERGY RECOVERY VENTILATOR STATUS - An energy recovery ventilator (ERV) monitoring and reporting system and a method of monitoring and reporting information on an ERV. In one embodiment, the system includes: (1) a processor configured to carry out a plurality of monitoring and reporting functions on the ERV based on a model, and types and locations of sensors, of the ERV, (2) a memory coupled to the processor and configured to store data gathered from the sensors and (3) a commissioning database associated with the memory and configured to contain commissioning data regarding the model of the ERV. | 05-16-2013 |
20130158719 | CONTROLLER EMPLOYING FEEDBACK DATA FOR A MULTI-STRIKE METHOD OF OPERATING AN HVAC SYSTEM AND MONITORING COMPONENTS THEREOF AND AN HVAC SYSTEM EMPLOYING THE CONTROLLER - A controller for an HVAC system, a compute-usable medium and an ERV are disclosed. In one embodiment, the controller includes: (1) an input terminal configured to receive feedback data from a first operating unit of the HVAC system, (2) an operation monitor configured to determine if the feedback data corresponds to a predetermined condition for the first operating unit and (3) a system director configured to operate a second operating unit of the HVAC system at a predetermined operating value corresponding to the predetermined condition and a number of occurrences of predetermined conditions associated with the first operating unit. | 06-20-2013 |
