Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to a multifunctional ejector heat pump unit for refrigeration, dehumidification and heating. Background technique [0002] With the rapid development of urbanization and the improvement of people's living standards, China's building energy consumption has grown rapidly. At present, building energy consumption has accounted for about 30% of the total energy consumption of social commodities, of which air conditioning and heating energy consumption account for about half of the total energy consumption of buildings. For China's current energy situation, which is rich in coal, poor in oil, and low in gas, the development and utilization of renewable energy such as solar energy and the recovery of industrial waste heat are the main measures for energy conservation and emission reduction, and are also the basis for China's sustainable economic development. What kind of "ener...
