Patent number: 7951327Abstract: A photocatalytic air purifier is disclosed. The photocatalytic purifier includes filter structures coated with a catalytic material such as titanium dioxide. One or more UV lamps are interposed between the filter structures. The catalytic layer reacts with airborne VOCs and bioaerosols when activated by the UV lamps to thereby oxidize the VOCs and destroy the bioaerosols. The photocatalytic air purifier does not need to be replaced or regenerated after a period of continuous usage. The photocatalytic purifier of the present invention substantially eliminates odors, VOCs, and bioaerosols from air directed through the fan coil. The photocatalytic air purifier includes a control system that optimizes operating costs. Because of these features, service, maintenance, and filter replacement are reduced to a minimum. At the same time, the well being of persons living in the space conditioned by the photocatalytic air purifier is improved.Type: GrantFiled: July 30, 2009Date of Patent: May 31, 2011Assignee: Carrier CorporationInventors: Bradley Reisfeld, Robert Hong Leung Chiang, Olivier Josserand, Kevin B.

Patent number: 6716406Abstract: In an air conditioning system which includes a catalytic air purifier, a control system is provided for sensing the level of predetermined conditions in a space and for responsively modulating the air purification process in a manner which optimizes the process in terms of its effectiveness and its economical use. The conditions that are sensed include the levels of VOC's, CO2, and biological contaminants, as well as degree of occupancy, relative humidity and air flow. The air purification process is modulated by varying the power to a UV lamp, turning one or more UV lamps on or off, varying the effectiveness of the catalyst, varying the volume or speed of the air flowstream and/or varying the relative humidity in the space.Type: GrantFiled: July 30, 2001Date of Patent: April 6, 2004Assignee: Carrier CorporationInventors: Bradley Reisfeld, Robert H.

Patent number: 5065593Abstract: A heat pump diagnostic and control system for controlling indoor coil freeze-up when in the cooling mode is provided. A low indoor coil temperature is sensed, the indoor fan speed is increased in steps up to a maximum to thaw the frost on the indoor coil. If this is not sufficient, the compressor speed is then reduced in steps until it is turned off and if necessary, it is held off until such time as the temperature sensor indicates thawing of the indoor coil of the heat exchanger. Diagnostic flow chart and control circuitry for accomplishing this control are disclosed.Type: GrantFiled: September 18, 1990Date of Patent: November 19, 1991Assignee: Electric Power Research Institute, Inc.Inventors: Kevin F. Dudley, Kevin B. Dunshee, Alan D. Abbott

Patent number: 5052186Abstract: An integrated heat pump and hot water system of the type having a variable speed compressor is controlled during a water heating mode, in which outdoor air serves as the heat source. The controlling is carried out on the basis of a field of outside temperature and water temperature. The compressor speed is controlled based on the outdoor air temperature, and the compressor is run at a maximum speed between a minimum outdoor temperature and a low temperature somewhat above the minimum, at minimum speed for outdoor air temperature between a maximum temperature and a high temperature below the maximum temperature, and at a speed that depends linearly on outdoor temperature for intermediate outdoor temperatures. There is a permissible temperature field or envelope bounded by the minimum and maximum outdoor temperatures, by minimum and maximum water temperatures, and by an efficiency floor and a torque limit ceiling.Type: GrantFiled: September 21, 1990Date of Patent: October 1, 1991Assignee: Electric Power Research Institute, Inc.Inventors: Kevin F.

Patent number: 5050394Abstract: An integrated air conditioning and water heating system provides cooling of a comfort zone, as required, as well as water heating. A variable speed compressor delivers compressed refrigerant first to a water heat exchanger and then to an outdoor condenser coil. From there the refrigerant cycles through an indoor evaporator coil back to the compressor. When the demand for water heating is above a predetermined amount and the cooling load is below a predetermined cooling load threshold, a full condensing mode is selected in which most of the heat from the comfort zone is used for water heating. If the cooling demand is high or if the water heating demand is low, a desuperheating mode is selected in which most of the heat is transferred to the outdoor air. The outdoor coil temperature is monitored and if it is above a safe limit, the desuperheating mode is selected. In the full condensing mode the outdoor fan is held off. In the desuperheating mode, the outdoor fan is energized.Type: GrantFiled: September 20, 1990Date of Patent: September 24, 1991Assignee: Electric Power Research Institute, Inc.Inventors: Kevin F.
