commercial refrigeration straight tube evaporator
commercial refrigeration straight tube evaporator. The straight tube evaporator is used in the ammonia refrigeration device. In order to improve the heat transfer effect of the straight tube evaporator, the commercial refrigeration is equipped with a mixer. Since the upper part of the vertical tube evaporator is opened, it is convenient for the operator to observe and maintain. The refrigerant has a large capacity, so when fresh water is used as a refrigerant, there is no danger of freezing and damaging the equipment. When salt water is used as the carrier refrigerant, commercial refrigeration corrosion is serious due to the contact between salt water and air. Corrosion inhibitors need to be added to the salt water, and the salt water can easily absorb the moisture in the air and reduce the mass concentration. It is necessary to check the relative salt water frequently. Density, adding solid salt to the brine.
spiral tube evaporator. The structure of the spiral tube evaporator is the same as the straight tube evaporator. Snake tube (coiled tube) evaporator is a water cooler commonly used in small Freon open-cycle commercial refrigeration refrigeration devices. It consists of several groups of copper tubes coiled into a serpentine tube. The serpentine tube is made of pure copper tube. The Freon liquid enters from the upper part of the serpentine tube through the liquid distributor, and the vapor produced by vaporization is exported from the lower part. The entire serpentine tube group is immersed in water (or salt water) commercial refrigeration, and the water circulates in the commercial refrigeration under the action of agitator. The coiled tube (coiled tube) evaporator has a poor heat transfer effect due to the denser arrangement of the coiled tube, the lower flow rate, and the underutilized heat transfer area of the lower part of the coiled tube.
