摘要： The invention relates to the atmospheric cold steam engine for generating mechanical energy through the use of atmospheric pressure and environmental thermal energy or excess of low temperature thermal energy released during production processes. The operating principle of the atmospheric cold steam engine is based on the characteristic of the materials to absorb or release the thermal energy during their transition from liquid to gaseous phases and vice versa. The purpose of the invention is to expand the possibilities of the heat pump by converting the thermal energy collected from the environment into the mechanical energy. The mechanical energy thus obtained can be used for the compressor of the same heat pump or be transformed into another type of an energy (electricity etc.) to be used by consumers in need.

摘要： Disclosed in the present invention is a method of generating a high-speed airflow, utilizing a device comprised of an air pipe (1), a circulating pipe (2) and a starting and controlling system (3). The starting and controlling system (3) is comprised of one or a combination of any two or more of a refrigerator (4), a circulating pump (5) and a heat exchanger (6). The method comprises the following operation steps: filling the device with a working medium; activating the starting and controlling system (3); after having been pressurized under liquid state, the working medium absorbing heat and being gasified, entering the air pipe (1), and generating the high-speed airflow. The method provides a method of utilizing a low quality heat source to convert a low-speed airflow into a high-speed or extremely high-speed airflow with relatively high use value. Utilizing the method, the thermal energy carried by the fluid in the nature is converted into the mechanical energy efficiently.

摘要： Connected in parallel to an expander (3) and a condenser (4) of a Rankine cycle (6) are n sets (S) each of which comprises a different expander (E) and a different condenser (C). Moreover, operation stopping means (B 1 -B n ) are provided for stopping operations of the expanders (E 1 -E n ) in the sets (S 1 -S n ) connected in parallel, and a pressure sensor (10) and a temperature sensor (11) are installed respectively in an inlet and outlet of an evaporator (2). An ECU (12) sets or releases at least one of the operation stopping means (B 1 -B n ) such that a measured value (T) of the temperature sensor (11) reaches a prescribed temperature value (Ts) which is equal to or less than a thermal decomposition temperature of a refrigerant (5) and which is set in advance, and the ECU (12) controls a rotational speed of a refrigerant pump (1) such that a measured value (P) of the pressure sensor (10) reaches a prescribed pressure value (Ps) set in advance.
