How do you see the refrigerating capacity of an ice maker?
Cooling method of refrigeration equipment:There are two kinds of direct cooling and indirect cooling. Direct cooling is to install the evaporator of the refrigerator in the box or building of the refrigerating device. The air in the air is directly cooled by the evaporation of the refrigerant, and the object to be cooled is cooled by cold air. This cooling method has the advantages of high cooling speed, small heat transfer temperature and relatively simple system. Therefore, it has been widely used.Indirect cooling by refrigerant refrigerator evaporator, so that refrigerant (such as saline) cooling, then input refrigerant refrigeration device box or inside the building, through the heat exchanger, cooling the air. This cooling method has low cooling rate, large heat transfer temperature difference and complicated system. Therefore, it is only used in less occasions, such as ice making in brine and cold storage with constant temperature.
The working principle of ice maker:1. the chilled water pump in the storage tank circulates continuously through the plate or compartment evaporator;2. after the compressor is operated, it is aspirated, compressed, exhaust, condensed (liquefied) and throttled - and then vaporized and vaporized at -10 to -18 degrees in the evaporator. The frozen water condenses into ice at the lower temperature of the evaporator surface at 0 degrees of water temperature. When the ice layer condenses to a certain thickness, when the evaporation temperature of the refrigerant reaches the temperature setting temperature, the defrosting is switched on, and the electromagnetic valve usually adopts the form of heat pump to remove ice, and then realize the next cycle.
According to the size of the head of the refrigerator, the standard refrigerating capacity can be calculated! The general refrigerator specifications have a corresponding relationship between the size of the refrigerator and the corresponding cooling capacity, which can be used for reference!
