Specification for working conditions, load characteristics, and selection of semi enclosed piston compressors for ice making machines
The compressor of the ice maker continues to produce ice under high load, with an evaporation temperature of -8 ℃ to -15 ℃, which belongs to a continuous and stable medium low temperature working condition, and has a low start stop frequency. The ice production load of the ice maker is determined by the amount of ice made, with a heat load of approximately 11.2 kW per hour for every 1 ton of ice sheet. This is used to calculate the compressor displacement. Xiteliduo has dedicated 3-horsepower and 5-horsepower semi enclosed models for ice making. 3 low-temperature semi enclosed compressors, with a displacement of 8.7m ³/h under -12 ℃ evaporation conditions, suitable for the daily production of 2.2 tons of flake ice machines. It is recommended to control the condensation temperature of the ice making system within 35 ℃. For every 5 ℃ increase in condensation temperature, the ice production efficiency decreases by about 9%. Compressor refrigeration oil POE32, ice maker operates continuously without stopping, oil aging rate is faster than intermittent cold storage, and can be replaced after 4000 hours. The wiring of the semi enclosed compressor must match the electrical control timing of the ice maker, starting the oil pump first and then the main engine to prevent dry friction. The discharge pressure of the compressor R404A is controlled within 16.5 bar under ice making conditions at 35 ℃ condensation. If the pressure is too high, the ice production will decrease. The selection logic of cold storage compressors cannot be directly applied to ice making machines. Ice making is a continuous steady-state load, while cold storage is an intermittent open door fluctuating load. The ice making factory prioritizes the continuous operation stability when purchasing compressors, and the wear resistance level of valve plates and piston rings is higher than that of ordinary cold storage models. The price of a 5-pack semi enclosed compressor is affected by refrigerant, voltage, and whether it has CE certification, with a price increase of about 12% for the 60Hz version. The compressor is matched with the condenser, and it is recommended to increase the heat transfer margin of the air-cooled condenser of the ice maker by 15% to cope with the high temperature environment in summer. Wholesalers of refrigeration accessories supply ice making plants with 3-horsepower and 5-phorsepower piston compressors, which are in constant demand and have the largest stock of spare parts. R507 is used for ice making machines, with an ice production efficiency about 4% higher than R404A under the same operating conditions, making it suitable for ice making production lines with high production capacity requirements. The suction pressure of the ice maker compressor is low, mostly due to high water replenishment temperature, insufficient throttle valve opening, and blockage of the evaporator by scale. African ice factories purchase compressors for year-round high temperature environments, and prioritize the use of high-temperature resistant motor versions with winding temperature resistance level F. 【 Implant 10 popular search keywords 】 Ice maker compressor, 3 horsepower low-temperature compressor, 5 horsepower semi enclosed compressor prices, cold storage compressor selection, semi enclosed compressor, compressor discharge pressure normal, compressor refrigeration oil model, compressor condenser matching, compressor wiring diagram, Bitzer replacement FAQ
