Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0024] like figure 1 As shown, a transcritical reverse cycle system according to an embodiment of the present invention includes a heater 2, an ejector 3, a cooler 4, a throttle valve 5, an evaporator 6, a gas-liquid separator 7 and a working medium pump 1 .

[0025] The saturated gas phase outlet of the gas-liquid separator 7 communicates with the gas injection inlet of the ejector 3 to form a reverse cycle system; the saturated liquid phase outlet of the gas-liquid separator 7 communicates with the inlet of the working medium pump 1, and the working medium pump 1 The outlet communicates with the heater 2 and the high-pressure inlet of the ejector 3 in sequence to form a positive circulation system.

[0026] The heater 2 heats the circulating working fluid in the supercritical pressure state to reach the supercritical state of high temperature a...

Abstract

The invention provides a transcritical reverse circulation system and method which take heat energy as the driving force, realize transcritical reverse circulation of a working medium and provide coldsource or heat source for the outside world. The transcritical reverse circulation system comprises a heater, an ejector, a cooler, a throttle valve, an evaporator, a gas-liquid separator and a working medium pump which communicate in sequence through pipelines, a saturated gas phase outlet of the gas-liquid separator communicates with a gas ejecting inlet of the ejector to form the reverse circulation system, a saturated liquid phase outlet of the gas-liquid separator communicates with the inlet of the working medium pump, and the outlet of the working medium pump communicates with the heater and the high-pressure inlet of the ejector in sequence to form a positive circulation system.

Description

technical field [0001] The invention relates to the technical field of realizing transcritical reverse cycle of circulating working fluid. Specifically, a transcritical reverse cycle system is a transcritical reverse cycle system that uses thermal energy as the driving force, and the circulating working fluid realizes a transcritical reverse cycle to provide a cold source or a heat source to the outside world. Background technique [0002] The thermodynamic reverse cycle is widely used in people's daily production and life, and is mainly used to provide users with cooling and heating functions to meet people's needs for cooling and heating. In the reverse cycle, the outside world acts on the system to transfer a certain amount of heat from the low-temperature object to the high-temperature object, thereby realizing the cooling function for the low-temperature object and the heating function for the high-temperature object. Therefore, the application of reverse cycle is main...
