Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If low pressure vapor is directly utilized for heating, then the system structure is simple, but the temperature is insufficient due to rising boiling point
Solution Approach 1:
The patent changes the temperature parameter of low pressure vapor by heating it to superheated vapor state, enabling it to reach temperatures sufficient for effective heating applications despite its low initial pressure and temperature
Solution Approach 2:
The patent introduces a heat exchanger as an intermediary device to transfer heat from high temperature heat source to the low pressure vapor, raising its temperature without directly complicating the core vapor utilization system
2Use of energy by moving object
If conventional vapor heating methods are used, then the system is simple, but energy consumption is high and thermal efficiency is low
Solution Approach 1:
The patent implements a feedback mechanism where the heating process itself generates vapor that is fed back into the system to continue heating low pressure vapor, creating a self-sustaining cycle that reduces external energy input and improves thermal efficiency to over 90%
Solution Approach 2:
The patent recovers energy from the heating process by capturing the vapor generated during heating of low pressure vapor and reusing it within the system, preventing energy waste and significantly reducing overall energy consumption
3Loss of energy
If low pressure vapor temperature is increased through heating, then thermal efficiency improves, but energy consumption increases
Solution Approach 1:
The patent establishes a continuous cycle where low pressure vapor is heated, generates vapor during the process, and that vapor is immediately reused to heat more low pressure vapor, ensuring continuous useful action that minimizes energy loss and maintains high thermal efficiency without requiring continuous external energy input

AI summary
The invention discloses an efficient vapor heat pump (VHP) and a method for utilizing low pressure vapor through enthalpy supplement and pressure boost, comprising the following steps: the low pressure vapor is heated into superheated vapor for enthalpy supplement; when a material is heated on a material heater, the pressure boosted and quantity increased saturated vapor will be condensed and sharply shrink in volume to generate a strong suction force so that the superheated vapor is sucked for spraying liquid boost pressure(SLBP), so as to utilize the pressure boosted and quantity increased saturated vapor; further, an artificial tornado is generated from vapor in relevant equipment by reference to the formation theory of tornado in nature and the strong suction force thereof, so as to enhance the suction force and improve thermal efficiency and compression ratio. The vapor heat pump, especially the tornado vapor heat pump(TVHP), has the advantages of high efficiency, low energy consumption, low cost and environmental protection due to small enthalpy difference between low pressure vapor and pressure boosted and quantity increased saturated vapor, less enthalpy supplement of superheated vapor ,and high pressure ratio for spraying liquid boost pressure(SLBP). Besides, the low carbon technology is used as a green energy source and thus the TVHP is widely applied to many fields.
