The invention discloses an injection-compression refrigerating system provided with a subcooler and utilizing low-grade heat energy. An outlet of an evaporator is connected with an inlet of a compressor, and an outlet of the compressor is connected with a first inlet of a preheater. A first outlet of the preheater and an outlet of an injector are connected with an inlet of a condenser, and an outlet of the condenser is divided into three ways. An outlet of the first way of the condenser is connected with a second inlet of the preheater, and an outlet of the second way of the condenser is connected with a first inlet of the subcooler through a first throttling device. A first outlet of the subcooler is connected with a driving fluid inlet of the injector. An outlet of the third way of the condenser is connected with a second inlet of the subcooler, and a second outlet of the subcooler is connected with an inlet of the evaporator through a second throttling device. A second outlet of the preheater is connected with an inlet of a generator, and an outlet of the generator is connected with a working fluid inlet of the injector. The injection-compression refrigerating system has the advantages that efficiency is high, energy consumption is low, heat sources with lower temperatures can be utilized, and the energy-saving efficiency is good.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to an injection-compression refrigeration system. Background technique [0002] With the continuous deepening of global industrialization, people's consumption of energy is increasing rapidly, which has brought about a series of problems such as energy depletion, global warming, and environmental pollution. Therefore, energy saving and emission reduction has become a technical hotspot in the world today. Among them, refrigeration technology consumes a large amount of energy and emits a large amount of carbon dioxide every year. Therefore, people urgently need to develop more efficient and energy-saving refrigeration technologies. [0003] Coupling the ejector and compressor to form an ejector-compression coupled refrigeration system, and taking advantage of the respective advantages of the ejector and compressor to improve the energy efficiency of the system is a current rese...
