Abstract

The invention discloses a thermodynamics circulation system achieving heat circulation through environment working media and application. The system comprises an environment working medium system and a thermodynamics circulation system body. The thermodynamics circulation system body comprises a circulating working medium evaporator, a circulating working medium expansion device, a circulating working medium condenser and a circulating working medium pump which are circularly connected in sequence. In addition, in order to convert low-level energy into high-level energy, an external heat source is further introduced. According to the thermodynamics circulation system achieving heat circulation through the environment working media, an artificial environment serves as a part of a low-temperature heat source and a high-temperature heat source of the thermodynamics circulation system body, phase change heat of the thermodynamics circulation system body can be transferred to the environment working media, the heat is transmitted to the thermodynamics circulation system body again by means of energy conversion of the environment working media, and the utilizing rate of energy is increased.

Description

technical field [0001] The invention relates to the technical field of thermodynamics, in particular to a thermodynamic cycle system that realizes heat cycle through environmental working fluid. Background technique [0002] Thermodynamic cycle (thermodynamical cycle) refers to the whole process that the working substance returns to its initial state after a series of state changes. It is also called cyclic process, or cycle for short. For example, when a heat engine is working, the working substance (such as steam in a steam engine) changes a part of the heat absorbed from the high-temperature heat source into mechanical work through a series of state changes, and discharges part of the waste heat to the low-temperature heat source, while the working substance itself Revert to the original state. Since the heat engine will work continuously, the working substance therein must carry out this cycle process again and again, so as to continuously absorb heat from the heat sour...
