Abstract

The invention discloses a solar phase-change heat storage absorption refrigeration fresh-keeping system, which comprises an absorption refrigerator consisting of a generator, a condenser, a throttle valve, an evaporator, an evaporation pump, an absorber, an absorption pump, a generator pump and a solution heat exchanger, and a heat source consisting of a solar collector, a temperature control valve, a heat storage water tank and a hot water pump, wherein the generator is communicated with the absorber through a two-way pipeline; the generator, the condenser, the evaporator and the absorber form a circulation pipeline; the evaporator is connected with a heating and cooling fan through a pipeline; and the refrigerating capacity is sent into a refrigerating chamber required to be refrigerated. The fresh-keeping system makes use of solar energy, saves the electric energy, reduces the running cost, and reduces the environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of solar energy conversion and utilization, and specifically relates to a solar energy phase-change thermal storage absorption refrigeration and fresh-keeping system, which uses solar energy as the driving energy and adopts phase-change thermal storage absorption refrigeration technology, which can air-condition fruits and vegetables, Chinese medicinal materials, etc. Keep fresh. Background technique [0002] At present, the modified atmosphere preservation technology is used to preserve the freshness of agricultural products such as perishable fruits and vegetables and Chinese medicinal materials. The agricultural products are placed in the fresh-keeping store, and the perishable agricultural products can be kept fresh for a long time by adjusting the temperature and humidity of the gas in the fresh-keeping store. Existing fresh-keeping stores generally use electric energy to drive refrigerators for refrig...
