The invention discloses an ammonia refrigeration system based on trace ammonia, and relates to the technical field of refrigeration. The ammonia refrigeration system comprises a non-freezing liquid storage barrel for refrigeration in a refrigeration chamber, a plate exchange type evaporator, a plate type condenser, a liquid storage tank and a compressor; a non-freezing liquid inlet, a non-freezing liquid outlet, a refrigerant liquid evaporation inlet and a refrigerant liquid evaporated gas outlet are formed in the plate exchange type evaporator; and an ammonia gas input pipe connected with an exhaust port of the compressor and a refrigerant liquid recovery pipe connected with the liquid storage tank are arranged on the plate type condenser. The efficient refrigeration effect is achieved, ammonia is only stored in the compressor, a plate heat exchanger, the liquid storage tank, the ammonia gas input pipe and a built-in channel connected with the ammonia gas input pipe, the use amount is very small, the injection amount of refrigerants is greatly reduced, environment friendliness is achieved, and due to the fact that ammonia is little, the ammonia refrigeration system serves as the evaporator, the injection amount of the refrigerants can be greatly reduced, and once the gas leaks in the open space, the gas density does not cause substantial injury to operators.
Description
technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to an ammonia refrigeration system based on trace amounts of ammonia. Background technique [0002] In the 21st century, as the society’s demand for the volume of the refrigeration industry is increasing, the carbon emissions caused by the refrigeration industry while contributing to society are also exceedingly large, and it is not friendly to the environment and has more destructive effects. Among them, the destruction of the ozone layer by Freon products has a great impact on the effect of the earth's room temperature. However, the refrigerant in the ammonia refrigeration system is anhydrous ammonia. Ammonia has no effect on the ozone layer and has zero effect on the earth's room temperature. Therefore, ammonia is the most environmentally friendly refrigerant. At the same time, the energy efficiency ratio of the ammonia system is on average equal to that of fluo...
