What is the difference between direct cooling and air-cooled cold storage

图片
  The meaning of direct-cooling cold storage: the cooling tube of the cold storage evaporator is directly fixed on the storage plate. When the evaporator absorbs heat, the air closer to the cooling tube cools faster, thereby forming natural convection in the co ld storage room , which is gradually realized Integral refrigeration, that is, direct cooling methods, such as common iron row pipes, aluminum row pipes, etc. Air-cooled cold storage means: the cold air generated by the cold storage evaporator is circulated through the fan to force the refrigerating air, so that the cold air is evenly distributed in each compartment of the cold storage to achieve cooling, that is, the cooling method that uses the fan to circulate the cold air. Direct-cooled cold storage Advantages of direct cooling cold storage: 1. Direct cooling type cold storage has simple structure, relatively low failure rate, and low cost resulting in low price. 2. It has a good cooling effect and is...

Which brand of brine ice block machine is better

图片
  Nowadays, there are many brands of salt water ice machines , and some customers do not know which brand to choose. Now let’s talk about the Guangzhou Bingquan brine type ice block machine. CBFI's brine ice block machine has 1-100tons daily capacity. In 2010,  CBFI® Launched a 100-ton 24 hours large-scale fluorine system ice block makers, which was successfully operated in Malaysia and was the first in the world. So what are the advantages of the CBFI brand? 1.Coil pipe evaporator is CBFI’s invention patent, it has a better evaporating effect with longer lifespan. 2.  CBFI adopts anti-corrosion technology with the surface of the salt water pool , two primers and one top coat, the paint surface is resistant to low temperature, long-term salt water immersion does not fall off, and the service life is more than 35% higher than similar products. 3. Customized ice molds of any size Provided by CBFI 4 .High power water agitator is used to replace the com...

How to perform leak detection on industrial ice machines?

图片
  Industrial ice machines need to be tested for leaks before running. Leak testing covers several aspects. Let’s get to know the methods of leak testing and how to solve the leaks. 1. Intuitive visual leak detection When R22 leaks, the refrigerant oil will also seep or drip out. Using this feature, you can judge whether there is a leak in the place by visual inspection or by touching it with your hands. When the leakage is small and it is not obvious to touch with your fingers, you can wear white gloves or touch the suspicious place with white paper to find the leakage. When oil stains are found somewhere in the refrigeration system, this may be a leakage point. Intuitive visual leak detection is simple and easy, without cost, but has great defects. Unless the system has a large leak that suddenly breaks and the system leaks liquid and colored media, the visual leak detection cannot be located, because the leakage area is usually very large. It is subtle, and ther...

Signs of normal operation of cold storage room

图片
  Some customers will ask what the state of the cold storage room is during normal operation. Today, I will give you a popular science knowledge about the normal operation of the CBFI cold storage room . 1. There should be no noise in the cylinder, only the normal and regular cold storage sound of the suction valve. 2. The suction temperature of the compressor should be 5-15℃ higher than the evaporation temperature (R22). 3. The condenser cooling water in the cold storage room should be sufficient, the water pressure should be above 0.12mpa, and the water temperature should not be too high. 4. For the new series of products, the reading of the oil pump pressure gauge should be 0.15-0.3mpa higher than the suction pressure 5. There should be no foot heating and frosting on the cylinder wall, and the surface temperature difference should not be greater than 15-20 degrees. For refrigerated or low-temperature systems, frosting of the suction pipe can generally r...

Problems to be paid attention to in the purchase of industrial chillers

图片
The editor of CBFI, a Chinese ice machine manufacturer , believes that the current domestic and foreign ice making machine have their own characteristics in terms of price, technology, and functions. When companies purchase chiller equipment, they can follow the "four requirements" to help companies purchase compressor equipment. When, choose the one that suits you best. 1. To compare equipment The same PLC is controlled and the same man-machine interface is operated, but the number and methods of control points are very different. There will be qualitative differences in the reliability, safety, stability, accuracy, and sensitivity of the equipment. Of course, the manufacturing cost of the equipment is different. The selling price will also vary. So don't be overly superstitious about PLC, but also in-depth comparison. 2. Pay attention to functions What are the equipment functions you most want, what are the main ones, and which supplier provides the e...

The cold storage's compressor suddenly stops during operation

  Some customers reported that the cold storage room 's compressor stops suddenly during operation some time ago. Now let’s analyze the reason and how to deal with it. 1. The cold storage room effect of air-cooled condenser is poor 【Fault Analysis】 ① The fan is not turned on. To ② The fan motor is damaged. ③ The fan is reversed. ④ The ambient temperature is high (above 40℃). ⑤ The condenser fins are blocked by oil and dust and the air does not circulate. 2. The heat dissipation effect of the cold storage room of the water-cooled condenser is poor ① The cooling water valve is not opened or opened too small, and the inlet water pressure is too low ② The water control valve is out of order. ③ The scale on the wall of the condenser tube is thick. [elimination method] Air-cooled: Use a wire brush to remove surface dust. Water-cooled: Check the cooling water volume. Remove limescale. 3. Too much refrigerant is charged in the system [Fault analysis] Excessive refrigerant causes...

what you must know about building an ice factory plant

图片
  The most common ice factories are edible ice and industrial ice factories. For the selection of an ice plant, many factors need to be considered, such as investment costs, operating costs, maintenance costs, water supply and preference for ice types. Ice manufacturers must design and manufacture ice cubes that can meet the needs of the local market with the existing equipment. Whether it is a new ice factory or an old ice factory, only by controlling lower costs will it be more competitive in the local ice market force. Therefore, the choice of automatic ice-making equipment and the competitive environment in the local ice-making market are factors that investors need to consider and investigate. In addition, investors also need to consider total production costs (including operating costs and the rate of return on invested capital). The high operating costs of ice-making plants can easily lead to increased ice-making costs and lower competitiveness. In the long ru...
