The invention discloses a cooperatively-controlled ice source heat pump compound system with jetting added enthalpy. Five running modes suitable for system overall cooperative control running are proposed and comprises (1) an ice source heat pump independent heating system, (2) an ice source heat pump double-heat-source heating system, (3) a scroll compression jetting added enthalpy auxiliary heating system, (4) a scroll compression jetting added enthalpy auxiliary refrigerating system and a (5) jetting-absorbing type refrigerating system. According to the cooperatively-controlled ice source heat pump compound system with the jetting added enthalpy, the prominent problems that when a traditional air cooling (water source) heat pump unit conducts low-temperature heating and high-temperaturerefrigerating, the exhaust temperature of a compressor is too high, the heating (refrigerating) amount and efficiency are significantly reduced, and the system can not stably and reliably run are solved. By applying the cooperatively-controlled ice source heat pump compound system with the jetting added enthalpy, the heating and refrigerating range of a traditional air conditioning unit is widened, the refrigerating and heating capability is comprehensively improved, and then efficient ultralow-temperature heating circulation and ultrahigh-temperature refrigerating circulation are achieved.
Description
technical field [0001] The invention belongs to the field of heating, ventilating and air-conditioning, and in particular relates to an integrated technology for synergistically controlling an ice-source heat pump composite system with injection enthalpy increase, and mainly studies an energy-saving system for multi-working-condition air-conditioning operation. Background technique [0002] With the development of the economy, air-conditioning applications are becoming more and more widespread, but energy consumption is also becoming increasingly tense. According to statistics, my country's building energy consumption accounts for more than 30% of the country's total energy consumption. Among them, the energy consumption of public buildings is huge and serious. Heating, air conditioning and hot water systems account for about 40% to 60% of building energy consumption. [0003] Under the dual pressure of severe resource scarcity and deteriorating environmental pollution, in re...
