Novel solar refrigerating device

The invention discloses a novel solar refrigerating device which comprises an ammonia pump, wherein an outlet of the ammonia pump is connected with an inlet of the ammonia pump through a solar heat absorbing plate, a water-cooling condenser, a flow regulating valve and an evaporator separately; a cooling water inlet and a cooling water outlet are formed in the water-cooling condenser; and a chilled water inlet and a chilled water outlet are formed in the evaporator. The novel solar refrigerating device has the advantages that: in use, the ammonia pump is used for feeding liquid-state ammonia to the solar heat absorbing plate and the water-cooling condenser; after being throttled by a flow regulating valve, the liquid-state ammonia enters the evaporator to be subject to evaporation and heat exchange; and the cooling capacity is taken away to enter a refrigerating environment through the chilled water inlet and the chilled water outlet. The novel solar refrigerating device is simple in structure, is high in ref
