How to use the ice machine
First, the ice making principle of the ice machine
1. The chilled water of the water storage tank is continuously circulated through the plate or the divided evaporator;
2. After the compressor is operated, it is subjected to suction-compression-exhaust-condensation (liquefaction)-throttle---in the evaporator, it is vaporized by evaporation at a low temperature of -10 °C to -18 °C. The chilled water continuously condenses into an ice layer on the surface of the lower temperature evaporator at a water temperature of 0 °C. When the ice layer condenses to a certain thickness, the evaporation temperature of the refrigerant reaches the temperature set temperature, that is, the defrosting solenoid valve is turned on, and the heat pump is used to de-ice, and the next cycle is realized.
Second, the use of ice machine skills
1. The ice machine should be installed away from the heat source, without direct sunlight, and the ventilation is good. The ambient temperature should not exceed 35 °C to prevent the condenser from dissipating heat and affecting the ice making effect. The floor on which the ice machine is installed should be solid and flat, and the ice machine must be level, otherwise it will cause no ice and noise during operation.
2. The gap between the back and left and right sides of the ice making machine should be no less than 30cm, and the top clearance should be no less than 60cm.
3, the ice machine should use independent power supply, dedicated line power supply and equipped with fuses and leakage protection switches, and must be reliably grounded.
4. The water of the ice machine should conform to the national drinking water standard, and a water filtration device should be installed to filter the impurities in the water to avoid blocking the water pipe and polluting the water tank and the ice mold. And affect the performance of ice making.
5. When cleaning the ice machine, the power should be turned off. It is strictly forbidden to use the water pipe to directly align with the body. Use a neutral detergent to scrub. Do not use acidic or alkaline solvents to clean.
6. The ice machine must unscrew the inlet hose head for two months to clean the inlet valve screen to prevent the sand mud impurities from clogging the water inlet, which causes the water intake to become smaller, resulting in no ice.
7. The ice machine must clean the surface of the condenser every two months. If the condensation is poor, the compressor components will be damaged. When cleaning, use a vacuum cleaner, a small brush, etc. to clean the condensed surface oil dust. Do not use a sharp metal tool to clean it to avoid damaging the condenser.
8. The water pipes, sinks, storage refrigerators and protective film of the ice machine should be cleaned every two months.
9. When the ice machine is not in use, it should be cleaned, and the ice mold and the moisture in the box should be dried with a hair dryer, and placed in a place free of corrosive gas and ventilated and dry, to avoid open storage.
Third, the use of ice machine considerations
1. The water used for ice making needs to be added with salt (dosing), and how much the modulation pump (piston pump) is automatically adjusted.
2, the main body of the ice machine is divided into two chambers of the outer cavity of the disk of a certain density of copper tubes (evaporation chamber), is the refrigeration thing.
3, the outer cavity is a very regular round stainless steel cavity center has a three-leaf blade and the distance between the inner wall can be adjusted by itself is generally 3 mm. There are several sets of evenly distributed copper nozzles above the ice skates!
4. The working principle is that the plunger pump sprays the water mixed with salt through several filters to spray the 0.2 kg of water onto the surface of the inner cavity and then the cold surface of the outer cavity instantly forms a 3 mm thick ice surface. Under the action of a rotating ice skate, the freshly prepared ice is dropped into small pieces and dropped into a storage bin.
