The reason why the ice maker system can make ice is achieved by the heat exchange and phase change between the refrigerant and the surrounding medium, such as water and air, running in the system: it runs to the liquid refrigerant in the evaporator (such as the boiling point of R404a) -46.1℃) After contacting with the drinking water at room temperature on the surface of the evaporator, it rapidly boils and gasifies (at this time, the drinking water is equivalent to the heating source); the high-temperature refrigerant after gasification is compressed by the compressor and transported to the condenser for heat dissipation and condensation Into a liquid state, and then repeated refrigeration cycles. There are two ways for high-temperature gaseous refrigerant to condense and dissipate heat in the condenser: ①Water-cooled heat dissipation, that is, 'to take away the high temperature of the refrigerant through tap water'; ②Air-cooled heat dissipation, that is, 'to take away the high temperature of the refrigerant through a fan' '. These two condensation methods correspond to different types of condensers, namely 'water-cooled tube condenser' and 'air-cooled condenser'. 1. Air-cooled ice maker As the name suggests, this type of ice maker is an ice maker that uses an 'air-cooled condenser' to dissipate the refrigerant in the ice making system. This type of ice maker is the most common in the market. The air-cooled ice maker uses fans and heat sinks to dissipate heat to the ice making system. Even some air-cooled ice machines have obtained higher energy efficiency levels certified by the country. However, if the ice machine needs to be used in a hot and humid environment, such as the kitchen, outdoors, or hot southern areas, we do not recommend the use of air-cooled ice machines. Because in these areas, the air temperature is too high to effectively help the system to dissipate heat, resulting in a serious decline in the ice efficiency of the ice making mechanism. What's more serious is that if the ice machine cannot 'exhaust heat' in time, the machine will even 'burn out' due to overheating. Advantages and disadvantages of air-cooled ice maker: Advantages: ①Low installation cost; ②Low water consumption, which can meet the requirements of areas with regulations on sewage discharge; ③Low energy consumption; Disadvantages: ①The heat emitted by the machine will cause the installation of the ice machine Area temperature rises; ②Depending on the air outlet and machine installation location, additional cooling vents need to be arranged on the side and above the machine body, resulting in increased machine processing costs; ③If this type of ice machine is used in high temperature areas, the ice machine production capacity may decrease. Air-cooled condenser 2. Water-cooled ice maker The water-cooled ice maker has the best effect in terms of heat dissipation in the ice making system, but it also means that this type of ice maker consumes a lot of water. Unlike air-cooled ice machines that use fans and heat sinks to dissipate heat, water-cooled ice machines use tap water running in a condenser tube to take away the heat of the gaseous refrigerant, thereby liquefying it. Generally, the condensed water of general commercial water-cooled ice machines is directly discharged through the sewer after flowing through the condenser, and cannot be recycled. Since water instead of air is used to dissipate heat from the ice making system, the output of the ice machine is not affected by the surrounding air temperature. However, because some cities and towns have related requirements for water resources protection, the use of water-cooled ice machines in this area is strictly restricted. Advantages and disadvantages of water-cooled
ice packing machines: Advantages: ①The temperature of the ice machine installation area will not rise due to the heat dissipation of the ice machine; ②The most effective way of cooling the ice making system; ③This type of ice machine can be used in any temperature environment. Disadvantages: ① Huge water consumption, for every 45 kg of ice made, the condensation system will consume 0.46 tons of water; ② It will significantly increase the cost of water and sewage for users of the ice machine.
