Description

Oxygen supply temperature regulation and control system Technical Field The utility model relates to the field of aquatic product oxygen supply equipment, in particular to an oxygen supply temperature regulation and control system. Background The aquatic seafood is used as a high-protein low-fat health food, has extremely strict requirements on storage environment, wherein the temperature and the oxygen concentration are key factors for influencing the quality and the fresh-keeping period of the aquatic seafood. The traditional aquatic product warehouse storage mode mainly relies on manual experience to regulate and control temperature and supplement oxygen, and has obvious defects. Firstly, temperature control precision is low, adopts simple ventilation or ice-cube cooling generally, is difficult to realize accurate accuse temperature, leads to the temperature fluctuation great in the storehouse, causes aquatic products seafood to deteriorate because of the temperature discomfort easily. Secondly, oxygen supply is unstable, and the traditional mode is mostly to directly let in air or oxygen in the storehouse, lacks effectual monitoring and regulation and control means, leads to oxygen concentration too high or too low easily, influences the normal respiratory metabolism of aquatic seafood, and then accelerates its putrefaction. In addition, the traditional mode relies on manual operation, and degree of automation is low, and not only intensity of labour is big, inefficiency, still is difficult to realize 24 hours incessant control and regulation and control, has further increased the storage risk. Finally, the traditional cooling mode has higher energy consumption, high running cost and unfavorable energy conservation and emission reduction.
