Description
Technical field
This utility model belongs to technical field of refrigerating devices, is specifically related to the circulation warm water defrosting structure of a kind of refrigeration system.
Background technology
In cold storage refrigerating system, when vaporizer (refrigeration fan) surface temperature is lower than 0 DEG C, vaporizer arises that frost, and the heat exchange property of vaporizer and air wide pre. drop can be produced large effect by being formed of frost. For the heat exchange property of vaporizer, the influence of frost is mainly reflected in several aspect: 1, the thermal conductivity several orders of magnitude less of the thermal conductivity of evaporator metal material of frost, and frost will increase thermal resistance in evaporator surface deposition; 2, after evaporimeter frosting, inner air runner reduced cross-sectional area, resistance increases so that flow reduces; 3, the frosting initial stage, the white grain of interruption makes heat exchange surface become coarse, and heat exchange property makes moderate progress, but after frost particle shape becomes frost layer, will affect heat transfer effect.
Water defrosting method is widely adopted as the conventional Defrost mode of one; In existing freezer water defrosting structure, it is that spray equipment is set in the inside of evaporation fan, spray equipment is connected with water tank by water pump, when needs defrost, open water pump and feed the water (can be saline) with certain pressure to spray equipment from water tank, the refrigerator pipes of vaporizer is carried out water spray defrosting, and the water after spray discharges freezer from discharge outlet; But it finds in using, and owing to the coolant-temperature gage of shower water is relatively low, causes that its defrosting effect is poor.
