20160102877 | SYSTEM AND METHOD FOR MONITORING AND CONTROLLING HEATING, VENTILATING, AND AIR CONDITIONING EQUIPMENT - A system and process is provided for remotely monitoring and controlling an HVAC system. Data and information relating to an HVAC unit is transmitted from the HVAC unit via the internet to a remote server. The server is programmed to detect and diagnose problems with the HVAC unit and to respond by sending command signals to the HVAC unit that address the problems or modifies the operation of the HVAC unit. | 04-14-2016 |
20130048319 | Kitchen Hood Assembly with Fire Suppression Control System - A kitchen exhaust hood assembly having a fire suppression system with built-in redundancy and monitoring capabilities is presented. The fire suppression system includes one or more fire suppression devices associated with the kitchen hood for extinguishing a fire within the vicinity of the exhaust hood. The fire suppression devices can be triggered by a series of manual actuators or fire sensors. A switching circuit including a plurality of switches operatively connected to the manual actuators or fire sensors triggers the fire suppression devices by enabling either a first or second actuating circuit. | 02-28-2013 |
20110079653 | Heated Makeup Air Unit - A heated air makeup unit comprising a heating chamber with a modulated furnace one or more non-modulated furnaces air temperature control and efficient furnace operation over a wide heating rate range. The utilization of indirect fired furnaces in the heated air makeup unit is disclosed. A control system is included to provide control of heated air temperature to within +/−1 F.° using continuous control of the heating rate of the modulated furnace and stepwise activation and de-activation of the non-modulated furnaces in response to heating demand. A programmed combustion air flow controller programmed to provide optimal airflow for any gas flow in a flow range of a modulating gas valve is provided to assure combustion efficiencies of at least | 04-07-2011 |
20090272372 | Kitchen Hood Assembly with a Combination Cleaning and Fire Suppression System - A kitchen hood assembly includes a combination hood cleaning and fire suppression system. The hood assembly includes a hood structure and a riser connected thereto. An exhaust blower forces an exhaust stream of air into the hood and through the riser. A combination hood cleaning and fire suppression system is incorporated into the hood structure. The combination hood cleaning and fire suppression system includes an elongated spray bar that is connected to a water source and includes a surfactant injector that injects a surfactant into the water being directed to the spray bar. In one mode of operation, the spray bar is effective to clean the hood assembly. In another mode of operation, when a fire is sensed in or in the vicinity of the hood, the same spray bar is utilized to inject an aqueous liquid into the hood to suppress the fire. | 11-05-2009 |
