Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to an injection-compression refrigeration system. Background technique [0002] The continuous development of human civilization has created a better life for people, but it also consumes a lot of energy and discharges a lot of waste into the environment. As human beings' demands on nature continue to increase, the warnings of nature are also becoming more and more serious. Therefore, while enjoying the convenience and comfort brought by modern technology, people also require the consumption of energy and the pollution of the environment to be minimized. Energy saving and emission reduction technology has become the focus of attention in the world today. [0003] Refrigeration technology is an important field of energy consumption. It is used in various aspects such as construction, chemical industry, energy, medical treatment, etc., and emits a large amount of carbon dioxid...
