    摘要: A lawn mower is powered by a quiet external combustion engine which is based on an Ericcson cycle which has been modified for more efficient combustion and higher temperature from the regenerative heat exchanger. Air is compressed in a compressor, then regeneratively heated in a heat exchanger by combustion exhaust prior to being expanded in a heated expander to generate power. The heated expander is in intimate thermal contact with the combustion chamber wherein combustion is efficiently supported by hot expanded air from the heated expander. The lawn mower includes a starter and conventional means for control, support and locomation.

    摘要: An air conditioning system with a common refrigerant supply, an engine-driven compressor circuit and a thermal compression circuit in parallel with the compressor circuit, a high efficiency compact thermal compressor which is either an ejector or a double vortex chamber flow inducer and a new control system which saves energy by unloading the mechanical compressor when thermal compression is fully operative. The hybrid system includes a check valve which prevents refrigerant flow from the compressor through the thermally powered compressor. Timers start the refrigerant pump of thermal compression circuit. Pressure switches sense operating pressure of the refrigerant. A refrigerant pump and a heat exchanger vapor generator generate high pressure refrigerant vapor which drives the thermal compressor. Refrigerant pump starts after initial cooling of passenger compartment is achieved by mechanical compressor circuit. Engine driven compressor is unloaded when outlet pressure of thermal compressor is high enough to drive system. THe precooling of the passenger compartment by mechanical compressor and subsequent unloading and deactivation of the engine-driven mechanical compressor permits lower fuel consumption. The system can operate with ozone-sparing refrigerants to replace CFC refrigerants, as well as with R12.

    摘要: This is a system for continuously cleaning warm-air furnace air filters by the reverse flow of air from the downstream, interior side of a portion of the filter to the upstream, exterior side of the filter which is rotating such that every portion of said filter is driven past the inlet of plenum or plenums at which locations reverse pressure generates reverse air flow to dislodge the dust and, thereby, clean and filter and to then drive the airborne duct into a fluid conduit which directs the collected dust into a combustion chamber, or into the exhaust vent pipe, or a dust receptacle. This assures a constantly clean filter, full air flow, and efficient heat transfer from heat exchanger into the occupied space requiring heat.

    摘要: The purpose of regenerative heat exchangers is to transfer the heat from one step or process of a cycle or system to an earlier step or process in the cycle or system such that the transferred heat is usefully absorbed rather than being discarded. The gas being heated is moved in a counter flow relative to the hotter fluid while being trapped between moving partitions (vanes) such that the gas so trapped is heated with a fixed volume with an increase in pressure as well as temperature. In some embodiments, the hotter as well as the cooler fluid is moved while trapped between moving partitions (vanes) so, as the cooler fluid being heated is thermally pressurized, the hotter fluid being cooled with a fixed volume is thermally pressurized. Materials and design details are selected to enhance the heat transfer between the two streams. The heat transfer at constant volume and thermal pressurization and depressurization will improve the energy efficiency of many processes that require a pressure increase/decrease along with heating/cooling. This invention accomplishes compression/decompression and heating/cooling with only one device rather than with two devices.

    摘要: The four processes of a reverse Stirling heat pump cycle; isothehermal compression with the heat of compression being transmitted to a constant, relatively high temperature sink, regenerative cooling, isothermal expansion with heat flow from a cooler, constant temperature source followed by regenerative heating from the heat derived from the previously compressed gas are all performed with constant rather than intermittent flow. A constant flow, constant volume counter-flow heat exchanger, placed between the compressor and expander, rather than an alternately heated and cooled heat storage matrix, provides for the steady flow regenerative heat transfer as required for a steady reverse Stirling cycle heat pump. This invention therefore provides for increased heat pump rate per unit volume.
