Abstract: A diagnostic monitoring system and method is employed for one or more vapor compression systems such as air conditioners and heat pumps having a compressor, an indoor air handler fan coil and an outdoor condensor. Temperature, voltage and current sensors are provided at the outdoor condensor to determine that at least one vapor compression system is operating properly. Data obtained from the sensors is wirelessly transmitted to a receiving-device for use by the systems' custodian or repair service provider and includes information concerning an occurrence of periods when one or more of the vapor compression systems are operating at an abnormal state.

Abstract: A vapor compression thermal control system having at least one electrically powered evaporator fan and an apparatus for preventing compressor overloading apparatus having a sensor that measures temperature of air entering the evaporator. That measured temperature is compared with at least one predetermined temperature setting to activate a predetermined evaporator blower on/off duty cycle when the measured temperature exceeds the predetermined temperature. Alternatively, the apparatus can have a sensor that measures temperature of air being used to cool the condenser, and that measured temperature is then compared with at least one predetermined temperature setting to activate a predetermined evaporator blower on/off duty cycle when the measured temperature exceeds the predetermined temperature. In either case, it is evaporator air flow that is modulated when the system is operated as a heat pump. For liquid cooled evaporators, however the circulation pump instead of the fan is modulated.

Abstract: A compact and lightweight electric generator for portable power applications employs a new engine design and integration approach for reducing engine, generator, and starter weight. A unique flywheel alternator/starter configuration that generates electrical power, rotates the engine for starting, provides inertia for smooth engine operation, pressurized air for cooling, and inertia for the alternator. An engine cowling provides rotating component protection, a fan shroud mechanism, cooling air ducts, and a cooling mechanism for handling large quantities of heat produced by rectified power conversion. An electrical hook up that allows the generator to provide transient surge capacity for starting inductive loads, or improved load leveling and fuel efficiency.

Abstract: A compact and lightweight hybrid vehicle power source employs an integrated engine hybrid electric boost power design that operates on a single battery bank for all electrical functions. An integrated flywheel, cooling fan and a single hybrid electric motor drive, engine starter, electromagnetic regenerative braking device and battery charging alternator are combined. The flywheel alternator/starter/hybrid-drive configuration generates electrical power for battery recharging and parasitic loads, rotates the engine for starting, provides boost power for faster vehicle accelerations, provides regenerative braking for faster decelerations, provides inertia for smooth engine operation, and provides pressurized air for forced convection cooling.

Abstract: Compositions and related methods for detecting leaks in HVAC/R components such as furnaces, portable gas heaters, swimming pool heaters, air conditioners, heat pumps, refrigerators, freezers, and other closed loop vapor compression systems, as well as heat exchangers. These compositions provide more sensitive detection of leaks in inaccessible areas of furnaces using low ODP and non-flammable compounds classified as hydrofluorochloro-ethers (HFCE's), hydrobromochlorofluoro-alkenes (HBCFA's) hydrofluoro-ethers (HFE's), and halogenated compounds which are either alkanes, alcohols, diones, acetates, ketones (e.g., butanones, pentanones), esters (e.g., propanoates), anhydrides, cycloalkanes (cycloparaffins), cycloalkenes (cycloolefins), heterocyclics (e.g., furans), and aromatics.

Abstract: A method and components for heating and hydrating foods and beverages using an exothermic and pressure generating chemical reaction are described. The exothermic reaction can be initiated by water, spark, electrical impulse, squib, friction, or shock to heat non-potable water and force the water through a membrane filter, thereby producing heated, potable water.

Abstract: An improved method and apparatus to prevent clogging of condensate drain lines with a biocide delivery system that prevents the growth of bioorganic growth in the liquid trap using time release biocide tablets or liquid biocide. When using solid biocide tablets erosion and dissolution of the tables is reduced. When using liquid biocides, combination of initial release followed by gradual release of residual liquid biocide in the drain water is attainable. Drain line are promoted from clogging while being installed anywhere on the drain line upstream of the liquid trap. The apparatus can also be incorporated with a liquid trap, allowing placement anywhere in the drain line.

Abstract: A method treats ordinary filters with an electrostatic material that will turn any filter into a passive electrostatic filter. A formulation is sprayed or otherwise applied onto the filter to increase the filter's ability to effectively reduce indoor air particulates and improve indoor air quality. The formulation includes a water-soluble dielectric formulation and can also be combined with a biocide.

Abstract: An acid test kit uses an indicator paper in a transparent tube which is easily and temporarily inserted in a Schrader-valve at a compressor suction inlet of a refrigeration system. The simplicity, yet sufficient accuracy, of the kit permits several different ways of holding the paper in the tube through a friction fit. One way is to sandwich the paper between a tapered holder which is folded to provide a nose for actuating the Schrader valve. Another way is to provide the paper on or over a cylindrical member. A method for using the test kit including allowing vapor refrigerant from the system to pass through the tube to the atmosphere.

Abstract: A formulation and method to treat and control microbial growth present in the water of climate control systems such as air conditioner air handlers, dehumidifiers, and humidifiers, which formulation can be entrained and dispersed into to living space air. Specifically, a formulation is provided in the form of a tablet or a spray for being applied onto a wetted surface element present in these systems which will effectively control the growth of microbes such as fungus, molds, bacteria, and virus present on the surface for an extended period of time. The formulations include at least two metals, at least two chelating agents, at least one surfactant, and at least one viscosity enhancing compound.

Abstract: A device for increasing the closing force of an AC powered contact in a circuit having a low-voltage AC source and a switch in a structure of the type used for activating electric devices by means of a low voltage such as heating pumps, air conditioners and refrigerators. In order to improve the closing force, a half-wave rectifier operates on the AC voltage to provide an output to energize the contactor. The closing force when the contactor receives the half-wave rectified voltage exceeds a force generated by the contactor when it receives an unrectified low-voltage alternating current of the same voltage and frequency value. The resulting improved closing force is accompanied by an improvement in the life time of the electromagnetic contactor and a decrease in the resistance of the electrical flow through the contactor.

Abstract: A field-installable and removable moisture and/or acid test kit and method is used for a vapor compression system. A moisture and/or acid indicator is provided in the test kit which is installed at a single point location upstream or downstream of the system compressor in a region where the system working fluid is in a substantially vapor phase. The test kit can be connected to the system by a threaded connection or a quick disconnect fitting. The moisture/acid indicator in the test kit detects the presence of moisture and/or acid by a diffusion of moisture or acid to the indicator via diffusion. Some magnification is provided in the test kit because the lower transport rates from the vapor diffusion mechanism requires a smaller mass of indicator material than has been used in conventional flowing liquid systems.
