Abstract

The invention relates to the technical field of refrigeration, in particular to a household refrigerator. An intelligent alive-keeping household refrigerator with a water change device comprises a controller, an ammonia nitrogen value sensor, a water circulating device, a heat exchanger and a reversing valve. When the controller detects that the ammonia nitrogen value exceeds a preset value, first, the water circulating device is started to filter excrement. Secondly, after the excrement of an aquatic product is accommodated in an alive-keeping chamber, if the aquatic product needs to be kept alive for long time, the ammonia nitrogen value of water has to be kept in a reasonable interval, and as a result, the water change device gradually adds fresh water and progressively changes water. When the ammonia nitrogen value is kept stable, large temperature fluctuation caused by water change is overcome, so that no adverse effect is played on the alive keeping of the aquatic product. Finally, heat is changed when the water is changed, so that electricity is saved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a household refrigerator. Background technique [0002] Aquatic products mainly include fish, shrimp and crab, shellfish, algae, special aquatic products and processed aquatic products. The production methods mainly include fishing and breeding, using ocean and inland waters for production, farmed fish are consumed in fresh form, caught products are consumed in the form of frozen products, and algae are consumed in the form of processed products. Fish are rich in nutrients, poor in skin protection, strong in enzyme activity, and contain a large number of spoilage bacteria on the surface of fish body, gills and digestive system. After the fish body is stiff, it begins to soften gradually and loses its elasticity. This is the result of the self-decomposition of the fish body by various enzymes contained in the fish body. This change is called autolysis. Although the autolyz...
