20ft reefer popular science 丨 Precautions for use

I. Summary of 20ft reefer

The 20ft reefer Container market is moving forward steadily and is entering a mature period. There are also outstanding highlights in the steady development, mainly represented by the trend of consumption upgrading – under the direction of increasingly diversified, personalized, and youthful demand, the product structure of 20ft reefer for household and light commercial 20ft reefer continues to be upgraded, and energy-saving, health, and intelligence have become important development directions in the industry.

II. 20ft reefer structure

The edge of the upper plastic plate is provided with a first groove and a second groove, the edge of the front end of the plastic container is covered with the upper cross gear, and the two side edges of the upper horizontal gear are parallel to the axis are bent inward along the circumferential direction to form a cavity. The cavity is threaded at the front end of the upper plastic plate., the two sides of the upper crossbar. The inner surface of the box body is covered with a foam tray, and the edge of the upper foam plate is fixed on the plastic container to form the inner liner of the box. The effect is that the air dissipation problem caused by the freezer’s sheet metal exposure is solved.

III. Frequently Asked Questions of 20ft Reefer

1.20ft reefer deactivated

Do not deactivate the 20ft reefer, in general. That will affect the service life. When deactivating, please clean the inside and outside of the 20ft reefer cabinet, open the door and cover it with a breathable cloth. Be careful not to seal.

2.20ft reefer food storage time problem

Especially when the temperature is below -18℃, the low-temperature environment can effectively inhibit the reproduction and growth of bacteria. The reproduction and growth of bacteria will be particularly slow, ensuring that food is temporarily stored without spoilage or metamorphosis.

Since the temperature of the 20ft reefer sticks to between 0-10℃, it can limit the growth of bacteria, but it cannot be prevented entirely. Generally speaking, refrigerators can only be kept fresh and can only be used as a storage room for a short period, and food stored for a long time should be kept in the freezer. However, food in the freezer can also be stored for a certain period, so please store it according to the expiration date of the instructions.

  1. Cleaning of the water outlet of the 20ft reefer

Sometimes accidentally causing food to fall inside and cause blockages, the 20ft reefer’s frosting water needs to be drained from the water outlet in the back. If you find water accumulating in the drain, be careful to see if it is blocked with a through-hole pin or soft plastic part.

4.20ft reefer safety issues

The grounding of the 20ft reefer must be guaranteed since the 20ft reefer and refrigerator are a class of appliances. Please be careful to check whether it is grounded. Also, please feel free to pay attention to whether the socket and power cord of the 20ft reefer is damaged. If damaged, it must be replaced in time.

  1. About 20ft reefer defrosting

Due to the high humidity of the environment, summer. The internal frosting speed is relatively fast. Generally, it is best to clean the 20ft reefer a month, pay attention to defrosting it is best to use the equipped defrosting shovel, if there is no defrosting shovel, you can use plastic devices, be sure not to use sharp metal devices to prevent damage to the liner or pipe dew. In winter, you can extend the defrosting time appropriately and clean up the cabinet when defrosting.

6.20ft reefer door body gel

The 20ft reefer temperature doesn’t need to be too low in summer. The thermostat can be adjusted to a weak gear. The temperature inside the cabinet will rise, the temperature difference between the inside and outside is relatively reduced, and the condensation phenomenon will be reduced.

In the summer rainy season, the surface temperature of the 20ft reefer door is low; because of the convection of hot and cold air, there will be condensation, which is normal, wipe off the condensation with a soft cloth, and it will never affect the performance of the 20ft reefer. Please feel free to use it.

Common faults and repairs of 7.20ft reefer

The 20ft reefer on-site inspection method is similar to a refrigerator. Standard methods are: test, see, listen, touch, and sniff.

Test: When the 20ft reefer fails, a multimeter can be used to measure whether the power supply voltage is standard. A multimeter can detect faults in control circuits, coils, and contacts of AC contactors, overcurrent protection relays, temperature relays, pressure relays, coils of solenoid valves, motors, etc.

② Look: see if the working pressure of 20ft reefer unit high and low-pressure indicator is average; whether the pressure gauge pointer swings violently, such as swing indicates that there is air mixed in the refrigeration system; see the frost on the surface of the 20ft reefer evaporators, such as evaporator frost dissatisfaction, ice, cover alternating frost or compressor suction end, housing or cylinder head frost, all is abnormal;

See if there is frost or condensation at the inlet end of the 20ft reefer drying filter, solenoid valve, and thermal expansion valve; if there is, indicate that there is blockage; see if the 20ft reefer shaft seal and the connecting parts have oil marks, if there are oil marks, then here is likely to be a leakage point; see if the oil level in the 20ft reefer compressor crankcase is standard; see 20ft reefer If there is too much dust on the surface of the condenser, if there is too much dust, it should be cleaned in time.

③ Listen: When the 20ft reefer compressor usually runs, it emits a uniform and slight “chilling, chilling” sound, while the valve piece is a slightly uniform “drip, drip” sound. The “dang” sound in the compressor crankcase is caused by the excessive gap between the crankshaft and the connecting rod;

The compressor emits a heavy friction sound, generally caused by insufficient lubricating oil to produce dry friction; the transmission belt emits “horn, horn” clapping sound, indicating that the drive belt is slipping or damaged; the thermal expansion valve emits intermittent, “flow sound, indicating that the refrigeration dose is small or ice blocking phenomenon.

Touch: When the 20ft reefer unit stops running, turn the 20ft Reefer compressor V pulley by hand, which should rotate flexibly. After the team runs for one h, touch the temperature of the compressor suction and exhaust pipeline by hand, the exhaust pipe should feel hot, touch the suction pipe by hand, should frost; handle the temperature of the bearing cover before and after the compressor generally does not exceed 70℃, if it is boiling or just slightly hot, it indicates that the system is not standard.

In the above we introduce you to some related issues about 20ft reefer function, pay attention to this issue when using, we should have some understanding of it, 20ft reefer is also more commonly used in life, for the purchase of 20ft reefer and use, we understand, hope later can help you choose.
