Embodiment Construction

[0015] The invention adopts the solar heat collector (composite parabolic concentrator) to absorb solar radiation as the energy input of the whole system, and through the effective integration of the power system and the refrigeration system, simultaneously outputs electric energy and cooling capacity to the outside. In order to ensure the continuous and stable operation of the system, a heat transfer oil heat accumulator is used to store the surplus solar radiation energy for use when the solar radiation is insufficient. In addition, an auxiliary heater is used as a backup heat source to continue to supply heat when the solar radiation is insufficient for a long time. The system provides energy. The solar heat collection and heat storage system uses heat transfer oil as the working medium, and ammonia-water mixed working medium as the thermal cycle working medium, which utilizes the variable temperature evaporation characteristics of the ammonia-water mixed working medium to e...

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).

Description

technical field [0001] The invention belongs to low-temperature thermal energy utilization and power engineering, in particular to a solar energy cooling and power cogeneration system based on ammonia-water mixed working medium. Background technique [0002] With the development of economy and society, the consumption of traditional primary energy is increasing, but the reserve of primary energy is limited. Therefore, the development and utilization of renewable energy has attracted more and more attention. There are abundant solar energy in nature, and the development and utilization of solar energy has important practical significance and engineering application value for alleviating environmental pollution and reducing the consumption of fossil fuels. In addition, users have diverse demands on energy. [0003] Existing solar energy utilization technologies are mainly solar power generation and solar refrigeration distribution systems. Solar power generation systems mainl...
