Today, when the economy tells development, ice machines are widely used in all walks of life. So, do you know about ice machines? Here's a look at you: 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 compartmental evaporator by the water pump; 2. After the compressor is running, it is inhaled - compression - exhaust - condensation (liquefaction) - throttling - and then vaporized by evaporation at a low temperature of -10 ° C to -18 ° C in the evaporator. 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, after the evaporation temperature of the refrigerant reaches the temperature control set temperature, the defrosting solenoid valve is often turned on and the heat pump is used to de-ice, and the next cycle is realized. Ice machine installation instructions: 1. Placement of ice machine (1) This unit should be placed in a place where air is circulated and clean around. (2) This machine should not be placed in the open air, and should not be exposed to direct sunlight or rain. You can't get close to the heat source around. (3) The environment in which the machine is used must not be lower than 5 ° C and not higher than 38 ° C. (4) There should be enough space around the machine, especially the back can not be less than 250mm. So that the machine is cooling. (5) Separate model installation Please adjust the grounding screw at the bottom of the machine with the level gauge to make the machine level stable. 2, the installation of the water system (1) Please connect the water source that meets the local drinking water standard. (2) Attach a filter if necessary to increase the drinking standard of water. (3) The water supply system must meet the following conditions: the water temperature is lower by 2 °C, the higher is not more than 38 °C, the water pressure is lower than 0.02 Mpa, and the higher is 0.8 Mpa; 3, the installation of the power supply (1) The power supply must be the same as indicated on the machine nameplate. (2) All lines must comply with national standards. (3) Must be reliably grounded, the grounding wire must meet electrical standards. (4) The voltage fluctuation shall not exceed ±10% of the rated voltage. Ice machine features: 1. Using an effective evaporator, the ice is made quickly and the ice cubes are crystal clear. 2, high-performance compressor, forced air cooling, cooling system optimization design, can fully meet the needs of ice making. 3, intelligent design, a variety of protection modes, the ice making process is completed automatically, and the system operation can be optimized according to different environmental temperatures. 4, fully enclosed structure to ensure the health of the machine and ice. 5. The microcomputer monitoring system can smoothly carry out the ice making cycle. 6. The temperature sensor detects the ice full automatic stop, automatically turns on the ice block, and the control mode is reliable. 7, the size of the ice block is adjustable, to adapt to different ice occasions. 8, user-friendly operation interface, work prompt function, easy to use. Through the above introduction, I believe that everyone has already understood the principle and use of the ice machine. To purchase a snowflake ice machine, please choose the YKKY brand FM snowflake ice machine provided by Beijing Changliu. Welcome to inquire.
