Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current heat engines and generators inefficiently convert low-temperature thermal energy into mechanical energy, leading to environmental pollution, while heat pumps produce thermal energy of inadequate quality for further conversion, and existing devices for converting low-temperature thermal energy into mechanical energy have limitations such as short-term operation or low energy efficiency.
Innovation Solution
The atmospheric cold steam engine utilizes two refrigerant fluids to cyclically absorb and concentrate low-temperature thermal energy from the environment, inducing changes in volume and pressure to generate mechanical energy, with a continuous operation principle that suppresses atmospheric pressure to transform thermal energy into mechanical energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat pumps are used to collect and concentrate low-temperature thermal energy, then thermal energy is transformed into higher temperature thermal energy, but the temperature is not high enough to be transformed effectively into mechanical or electrical energy
Solution Approach 1:
The patent utilizes phase transitions of the working substance (evaporation and condensation) to enable effective energy conversion. The substance evaporates at low temperature absorbing thermal energy, then condenses at higher temperature releasing energy that can drive the piston, thus resolving the temperature insufficiency problem while maintaining effective energy conversion
Solution Approach 2:
The patent changes the parameters of the working substance through cyclic compression and expansion. The compressor increases pressure and temperature of the vapor, while the expansion chamber allows pressure equalization and condensation. These parameter changes enable the substance to effectively transfer thermal energy into mechanical work
2Power
If conventional heat engines operate under the Carnot cycle within a certain temperature range, then mechanical energy is generated, but low-temperature thermal energy is released into the environment as waste
Solution Approach 1:
The patent makes the system self-sufficient by using the low-temperature thermal energy that would otherwise be waste to drive the evaporation process. The working substance absorbs this low-grade thermal energy during evaporation, converting it into useful mechanical work through the piston mechanism, thus eliminating energy waste and creating a self-sustaining cycle
Solution Approach 2:
The patent employs phase transitions to capture and utilize low-temperature thermal energy. During evaporation, the working substance absorbs low-temperature thermal energy from the environment or waste heat sources. This absorbed energy is then converted into mechanical work through condensation-driven pressure changes, transforming previously wasted energy into useful power
3Power
If devices are designed to convert low-temperature thermal energy into mechanical energy using phase transitions, then mechanical energy is generated, but the devices can only operate in short-term mode until all liquefied gases evaporate
Solution Approach 1:
The patent establishes continuous operation by implementing a closed cyclic process. The working substance continuously evaporates, compresses, condenses, and expands in a repeating cycle. The piston mechanism and valve system ensure that each cycle regenerates the conditions for the next cycle, enabling indefinite continuous operation rather than single-use depletion
Solution Approach 2:
The patent employs periodic cyclic action with distinct phases: evaporation, compression, condensation, and expansion. Each phase prepares the system for the next phase in a repeating sequence. The periodic opening and closing of valves, combined with the reciprocating piston motion, creates a self-renewing cycle that maintains operation indefinitely

AI summary
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.
