Solar energy system combined cooling and electricity based on ammonia water mixed refrigerant

Abstract

The invention provides a solar energy system combined cooling and electricity based on an ammonia water mixed refrigerant. The system comprises a steam generator (106) which adopts the ammonia water mixed refrigerant, makes the solar energy as an energy source of the energy, and provides the energy for the whole solar energy system combined cooling and electricity; a first separator (107) used for separating the high-temperature high-pressure ammonia water wet steam generated by the steam generator (106) to be ammonia-enriched steam and ammonia-poor solution, wherein the ammonia-enriched steam is powered after acting of a bleeder turbine (110), the ammonia-poor solution is mixed with ammonia-enriched dead steam discharged from the bleeder turbine (110) through cooling and depressurizationin sequence, passes through a heat regenerator (115), enters a second separator (119), is congealed and depressurized by the ammonia-enriched steam separated from the second separator (119), and finally refrigerating capacity is produced through an evaporator (112).
