Abstract

A heat engine with heat regeneration is characterized in that the structure of the engine incorporates a heat pump, wherein air fed into a combustion chamber and/or a heat transfer fluid fed into a heat exchanger of a heat source is heated by a condenser of the heat pump, and air exhausted into the external environment and/or heat transfer fluid fed into an external radiator is cooled by an evaporator of the heat pump.

Description

Тепловой двигатель с регенерацией тепла тепловым насосом Heat engine with heat recovery by heat pump
Область техники Technical field
Изобретение относится к двигателестроению и может быть использовано в тепловых электростанциях, самолётах, автомобилях и других процессах для преобразования тепловой энергии в механическую. The invention relates to engine building and can be used in thermal power plants, aircraft, cars and other processes for converting thermal energy into mechanical energy.
Предшествующий уровень техники Prior Art
Известен такой способ повышения КПД тепловых двигателей, как регенерация тепла. There is such a way to increase the efficiency of heat engines, as heat recovery.
Таковой способ сводится к нижеследующему: This method boils down to the following:
Воздух подаваемый в камеру сгорания и(или) теплоноситель подаваемый в теплообменник источника тепла подогревается «горячим» контуром регенератора, а воздух выпускаемый во внешнюю среду и(или) теплоноситель подаваемый во внешний радиатор охлаждается «холодным» контуром регенератора. В качестве регенератора используются теплообменники.The air supplied to the combustion chamber and (or) the heat carrier supplied to the heat source heat exchanger is heated by the “hot” regenerator circuit, and the air released into the external environment and (or) the heat carrier supplied to the external radiator is cooled by the “cold” regenerator circuit. Heat exchangers are used as a regenerator.
Недостатки прототипа : Prototype Disadvantages:
Теплообменник не позволяет достаточно снизить температуру воздуха выпускаемого во внешнюю среду и(или) теплоносителя подаваемого во внешний радиатор - температура всё ещё достаточно выше температуры внешней среды, это приводит к излишним теплопотерям и, как следствие, к заниженному КПД двигателя. The heat exchanger does not allow to sufficiently reduce the temperature of the air released into the external environment and (or) the coolant supplied to the external radiator - the temperature is still sufficiently higher than the ambient temperature, this leads to excessive heat loss and, as a result, to an underestimated engine efficiency.
Раскрытие изобретения Disclosure of invention
Техническим результатом изобретения является: The technical result of the invention is:
Повышение КПД теплового двигателя. Increasing the efficiency of a heat engine.
Технический результат достигается следующим образом: The technical result is achieved as follows:
В качестве регенератора вместо теплообменника используется тепловой насос. Тепловой насос позволяет значительно снизить температуру воздуха выпускаемого во внешнюю среду и(или) теплоносителя подаваемого во внешний радиатор - температура приближается к температуре внешней среды, это приводит к снижению теплопотерь и, как следствие, к повышению КПД двигателя. A heat pump is used as a regenerator instead of a heat exchanger. The heat pump allows you to significantly reduce the temperature of the air released into the external environment and (or) the coolant supplied to the external radiator - the temperature approaches the temperature of the external environment, this leads to a decrease in heat loss and, as a result, to an increase in engine efficiency.
Варианты осуществления изобретения Embodiments of the invention
За основу берётся тепловой двигатель с регенератором в виде теплообменника. В конструкцию интегрируется тепловой насос. Конденсатор теплового насоса через теплообменник подключается вместо «горячего» контура регенератора, а испаритель — вместо «холодного». A heat engine with a regenerator in the form of a heat exchanger is taken as the basis. A heat pump is integrated into the design. The heat pump condenser is connected through a heat exchanger instead of the "hot" regenerator circuit, and the evaporator - instead of the "cold" one.
Промышленная применимость Industrial Applicability
Изобретение может применяться в тепловых электростанциях, самолётах, автомобилях и других процессах для преобразования тепловой энергии в механическую. The invention can be used in thermal power plants, aircraft, cars and other processes for converting thermal energy into mechanical energy.
