19 Stirling Engines For Heat Pumps Stationary Power And Totalenergy Systems

introduction

Stirling engines are under study or development for a variety of non-automotive applications that can be broadly classified into three groups: heat pumps, stationary power generation and total energy or co-generation systems.

A hear pump is a device used for heating or cooling, usually as part of the air conditioning system of a building. In the heating mode it draws heat at ambient temperature from a thermal reservoir, such as a river, lake, or the ground around the building. It 'pumps' the heat to a higher temperature for rejection from the pump to heat the building. The energy is eventually dissipated by conduction or convection from the building at approximately ambient temperature. In the cooling mode, the situation is reversed. Meat is drawn from the building at a low temperature and rejected to a heat sink, the same river or lake that served earlier as the source.

Stationary power generation embraces a wide range of energy conversion activity but is usually interpreted to mean the production of electric power. The same term can also be applied to pneumatic (air compression) or hydraulic power systems operating in a fixed location or as the auxiliary power systems on board an automotive, flight, or marine vehicle. Power levels can range from the few watts of an unmanned navigation signal generator to the gigawatts of a base-load electric-power utility-system. Current interest in Stirling engines for stationary power is concentrated in modular engines of 500 to 2000 horsepower utilizing municipal, agricultural and industrial wastes and small low-power engines.

A total-energy or co-generation system is a jargon term employed to describe an ensemble of machinery used principally in buildings to provide all or most of the services required, i.e. electricity for lighting and power purposes, heating, cooling, and hot and chilled water, utilizing an input energy source such as coal, gas, oil, or a waste product including an exhaust thermal stream.

A total-energy system will therefore include a stationary power generator and, in all probability, a sub-system operating as a heat purnp. However, a stationary power generator or heat pump is not necessarily part of a total-energy system not need the heat pump incorporate a stationary power generator. Nevertheless, they can be related and seem to fit together in a common grouping although from hereon we shall consider them all under separate headings.
