Counter Top Cooler can be mainly divided into three types: tube type, corrugated plate type and air-cooled type. Among them, the tube-and-tube heat exchanger can be divided into double tube type, vertical type, horizontal type, floating head type, etc. The characteristic of the tube-and-tube heat exchanger is that the water used for cooling flows through the inside of the tube, while the oil is Flowing through the distance of the tube, the centrally arranged folding plate allows the oil to baffle, and the two-way or even four-way movement method it uses makes its cooling effect more intense; the corrugated plate heat exchanger can also be divided into herringbone and oblique corrugation It mainly uses the contact points placed in the corrugated structure, which allows the fluid to form turbulent flow when the flow rate is not high, which greatly improves the heat dissipation effect; the air-cooled heat exchanger can be divided into direct type and fixed type. It has the characteristics of simple structure, small size, light weight and convenient use. Next, we will take the tubular heat exchanger as an example to explain the working principle of the heat exchanger.

The tubular Counter Top Cooler is mainly composed of two parts: the outer shell and the inner heat exchanger body. The outer shell includes a cylinder, a water divider cover and a water return cover. There are oil inlet pipes, oil outlet pipes, water inlet pipes, and water outlet pipes, and are attached with oil drain, drain, exhaust screw plugs, and zinc rod device holes. Thermometer interface, etc. The heat exchanger body includes heat exchanger tubes, fixed orifice disks, movable orifice disks, baffles, etc. The two ends of the heat exchanger tube are connected with the fixed and movable orifice disks, and the fixed orifice disk is connected with the outer body flange. The movable orifice disk can be freely elastic in the outer body to eliminate the influence of temperature on the heat exchanger tube due to thermal expansion and contraction. . The baffle can enhance the heat transfer and support the heat exchanger tube.

The heat medium of the tube-and-tube Counter Top Cooler flows from the receiving inlet on the cylinder to the receiving outlet in a zigzag manner through the baffle channels. The heat exchanger medium adopts double-pipe-pass activity, that is, the heat exchanger medium enters half of the heat exchanger tubes from the water inlet through the water divider cover, and then flows from the return water cover into the other half of the heat exchanger tubes, and enters the other side of the branch. Water cover and outlet pipe. In the process of double-pipe pass flow of the cold medium, the waste heat released by the absorbing heat medium is discharged from the water outlet, so that the working medium maintains the rated working temperature.

        First, there is less air-conditioning. The matched unit power is about 30% to 40% less. Usually 1.0 cubic Upright Freezer matches with 1/2HP compressor, but the compressor installed in low cost Upright Freezer is 1/3 or 3/8HP.

        Second, the cooling temperature is high. The working temperature is marked chaotically, sometimes marked as 0 degrees. The user actually reflects the summer freezing room temperature between 8 degrees and 12 degrees. This brings safety risks to food preservation that requires a constant low temperature environment.
The third cooling rate is slow.

　　 Low-cost Upright Freezer's compressor has low power, which is suitable for reducing the condenser area, condenser fan power and air volume, and evaporator area of ​​the system. Less refrigeration, slow refrigeration, only used in winter, spring, autumn, or only used in the northern region, means that it can be roughly coped with. On the contrary, this Upright Freezer has high temperature during the day or night in summer, or contains a lot of food, and the food turnover is large. The temperature of the Upright Freezer is low, and the hygiene and safety of the stored food cannot be guaranteed.

        The above is related to performance, so is there anything else in the performance of the bad Upright Freezer? Of course there are, such as service life and later expenditures.

       Upright Freezer Life: The low price Upright Freezer with inferior structure does not have any steel frame. The door frame is assembled after the cabinet body is foamed. This Upright Freezer is difficult to move multiple times. The door frame will fall off within a few years and is difficult to repair. Low-quality and low-cost Upright Freezer cabinets are selected for low-quality materials. If the materials are cheap, replace them with stainless steel or aluminum plates, copper pipes with aluminum pipes or composite steel pipes, and ABS engineering plastics with ordinary plastics. The material of Upright Freezer is so thick and thin, and copper becomes iron, its performance and service life are also reasonable.

        Expenses after use: I saved a little when I didn't buy the Upright Freezer, but continued to spend more money after years of use. First of all, because Upright Freezer has been used continuously for many years, the electricity bill is quite high. The power consumption is mainly reflected in the thermal insulation performance of Upright Freezer.

The sudden epidemic spread to the world at a rapid rate, and the destructive power and harm brought about it brought great pain and blow to the entire human society and development. Although China has temporarily controlled the epidemic, it is believed that after the epidemic, everyone is concerned about food hygiene and food hygiene. Health issues have become more sensitive and concerned, and more food businesses will begin to choose refrigerators that can ensure food hygiene to store food, and Upright Freezer is the first choice for retail operations.

Regarding how the Upright Freezer should be used correctly after purchase, I will give you a detailed introduction today:

1. The newly purchased or moved Upright Freezer should be left for 2 to 6 hours before turning on. Before use, run the empty box for 2 to 6 hours. Do not start immediately after shutdown, wait for more than 5 minutes to avoid burning the compressor.

2. The freezer should be placed on a flat floor. The indoor environment where the freezer is placed should be well ventilated and dry. The top should be more than 50cm away from the ceiling, the left and right sides should be more than 20cm away from other objects, and the back should be more than 20cm away from other objects.

3. When the freezer is used, hot food must be cooled to room temperature before being placed in the showcase. For vertical (air-cooled) refrigerators, do not keep food too close to the air outlet when storing food. For direct-cooled refrigerators, manual defrosting is required when the frost thickness reaches 5 mm.

The above introduction of the relevant knowledge about the operation and use of the Upright Freezer, I hope to help friends who have this need!

1. Upright Freezer's cooling performance

The performance of refrigeration is mainly based on the comprehensive evaluation of the refrigeration effect and cooling speed of the freezer. As long as these two aspects can meet certain standards, it can be regarded as a freezer with better refrigeration performance, just like if we store it in a freezer. When there is a lot of food, you can observe the refrigeration effect of the freezer to see how long the food in the freezer can achieve the effect of low-temperature preservation. The vertical freezer has the advantage that it is helpful for us to store food, and it is better to choose the suitable one. The temperature range preserves our food. Today's refrigerators will use vertical microcomputer temperature control technology and electronic microcomputer-designed temperature controllers. The temperature controller can automatically adjust the overall temperature of the refrigerator to ensure the freshness and safety of the food stored in the refrigerator. .

2. Understand the energy saving of freezer

The power consumption of refrigerators is a problem that many businesses who need refrigerators will consider. They will give priority to some low-energy refrigerators. In fact, I tell everyone that it is not necessarily a low-energy refrigerator that we use is good. I also need to use it according to our own The actual demand. Although some refrigerators have relatively low energy consumption, their power is also relatively small. If we want to store more food when we use it, the power of the refrigerator will not meet the requirements and the cooling requirements , Affect our use, when we choose the freezer, we should not deliberately pursue the lowest power consumption of the freezer, so as not to affect our use.

3. The design of the freezer

At present, when people buy freezers, they actually see the overall appearance of the freezer at first glance to see if the appearance can meet our requirements. Especially commercial freezers are used in supermarkets and convenience stores with a relatively large flow of people. Locally, the aesthetic appearance is very important, but the practicality of the freezer must also be considered, and whether the raw materials used in the freezer can be durable and corrosion-resistant.
