Embodiment 3

[0032] In Example 3, when the four-way reversing valve 5 is in state 1, the first heat exchanger 3 becomes the condenser of the heat pump system, providing a heat source for the T-shaped tube component separator 1; The second heat exchanger 7 becomes the evaporator of the heat pump system, and provides a cold source for the T-shaped tube component separator 1, at this time along the direction of the two mixed working medium outlets 1b and 1c of the T-shaped tube component separator A temperature difference is established; the control of the temperature difference is realized by controlling the compressor 4 . The single-phase or two-phase mixed working medium is passed into the mixed working medium inlet 1a of the T-shaped pipe component separator through a straight line, such as image 3 The direction indicated by the middle arrow flows into the impact-type T-shaped component regulating system, and then the mixed working fluid is impacted by the wall of the T-shaped tube compo...

Abstract

The invention discloses a temperature-difference-driven T-shaped component adjustment system for mixed working medium component adjustment, which consists of a T-shaped tube component separator and a temperature difference control system: the T-shaped tube component separator has a mixing The working fluid inlet and the two mixed working medium outlets are equipped with flow regulating valves to adjust the flow of the working fluid on the pipe sections of the two mixed working medium outlets of the T-shaped pipe component separator; the temperature difference control system can be A heat pump system arranged between two mixed working medium outlet pipe sections; or composed of two heat exchangers and a temperature difference generating component group arranged between the two heat exchangers, the temperature difference generating component group is used for the two heat exchangers A constant temperature difference is generated and maintained in the heater. The component adjustment system of the present invention constructs a controllable temperature difference at the two outlets of the T-shaped tube component separator through the temperature difference control system, and realizes efficient and controllable single-phase and multi-phase mixed working fluids flowing into the T-shaped tube component separator. Component adjustments.

Description

technical field [0001] The invention belongs to the technical field of adjusting mixed working fluid components in thermal cycles, and in particular relates to the efficient and controllable separation of mixed working fluid components in high-efficiency cycles based on non-azeotropic working fluids. Background technique [0002] In recent years, with the increasingly prominent problems of energy shortage and environmental degradation, renewable energy such as solar energy and geothermal energy have made great progress. The main technical means for their development and utilization include new power cycles represented by organic Rankine cycle and The vapor compression reverse cycle is the representative refrigeration / heat pump cycle. In order to realize the efficient conversion of various energy flows under variable working conditions, on the basis of traditional circulation, many scholars have introduced non-azeotropic mixed working fluids to reduce irreversible losses thro...
