Pre-season maintenance

    A. Pre-season maintenance: Check the perimeter of the unit and the air inlet for obstructions before the start of the season.

B. Maintenance and use of the unit: Pay attention to the cleaning of the chassis. Press the “Cleaning” button every day to prevent bacteria and odors from occurring. Yuyao air cooler, Cixi air cooler

C. Unit cycle maintenance: The unit runs for 1-2 months. If the curtain is wet, the filter is clogged or the chassis is too dirty, it should be cleaned to avoid machine failure.

D. End of season maintenance: To prevent freezing damage to the body and mosquito breeding, when the water is turned off for a long time, turn off the tap water, then press the cleaning button to clear the water and cut off the power.

E. Internal cleaning of the unit: If the unit is operated for a long time, in order to ensure the cooling effect, the machine must be cleaned once every 1 or 2 months;

    Maintenance and precautions

How to make the chiller the most efficient? How to operate more efficiently, safely and economically? The maintenance of this chiller is an important task.

    After the air-cooling system is operated for a period of time, the filter will accumulate dust and increase the air resistance. The air-conditioning indoor unit leaks, which causes the air volume to decrease or block, so it needs to be cleaned regularly.

 

    After long-term operation, due to the heating of wires and components, the joints may loosen and the second-hand air conditioner may be detached, resulting in poor contact and lack of phase, which needs to be checked and processed regularly.

    Accidents caused by failure of protection devices such as water flow switches, high and low voltage switches, safety valves, etc., should be replaced in time if found.

    Note: When the air conditioner is being repaired, be sure to turn off the power. It is better to turn off the power for a while, because static electricity will be generated for a long time. After the power is turned off, the static electricity will not disappear immediately. Therefore, it is safe to be repaired.

Most of the cold storages we have made are divided into many types, high temperature warehouses, low temperature warehouses, ultra-low temperature warehouses, etc. How to choose the internal machine of the cold storage? Is it a choice of cooling fans or piping? This is a problem that needs to be considered.

Generally, we do high temperature storage. We all recommend using a cold air blower. It is easy to install. If it is a large cold storage, if the external height of the cold storage is high, the internal machine adopts the exhaust pipe. The installation is very inconvenient and has certain safety hazards. The air blower is easy to assemble and disassemble, and is suitable for use in high temperature warehouses.

For low-temperature cold storage or ultra-low temperature cold storage, we recommend using a tube, a low-temperature cold storage on the market, and a large number of external tubes. From the long-term perspective, the use of the pipe, the cooling capacity in the cold storage is uniform, energy saving, but also has certain shortcomings, the price is relatively high, compared to the chiller installation is not convenient.

Generally, the low temperature cold storage of minus 18 degrees or minus 25 degrees is completely ok, and there is no need to worry about frosting. However, if it is an ultra-low temperature cold storage, it is recommended to use a tube.

The air cooler has a unique role in the preservation process of food. During the harvesting season of agricultural products, the indoor temperature is relatively high, and the temperature difference between day and night is relatively large, which is not conducive to fresh storage. The easiest way to face this situation is to find a place where the temperature is stable and cool to preserve agricultural products, such as caves, caves, cellars, etc., but these methods cannot control the temperature arbitrarily, the freshness is not enough, and the shelf life is also short. ,Time-consuming. If you really want to save agricultural products for a long time, the best solution is to create a controllable low-temperature environment by hand. The Beidou air cooler has an absolute advantage in refrigeration. Yuyao air cooler, Cixi air cooler

     Beidou air-conditioner replaces traditional refrigeration materials with water--Freon as a refrigerant, using high-efficiency "water evaporation" cooling technology, using the characteristics of water absorption during evaporation to reduce the indoor air temperature (dry bulb temperature), Use cooling water to contact the air. The detailed process is as follows: the outdoor humid fresh air passes through the cooling core component of the cooling fan, and exchanges temperature with the cooling water. Through the heat transfer, the temperature of the indoor air can finally drop to the temperature of the wet bulb. Moreover, when the air cooler is working, it can perform air freshness conversion indoors and outdoors, and can keep fresh and moisturize for a longer period of time.

Larger manufacturers of air-conditioners in the workshop are relatively concentrated, generally based on “channel sales”. Except for the local production plants, other regions do not operate on their own. Among them, the relatively excellent “Aolan” has formed a relatively sound sales network throughout the country. The production enterprises with independent research and development capabilities also do a good job in export, and also occupy a certain share in the international market. Shandong chillers are relatively more sold in the market. The market price of chillers is relatively stable on average, and there is not much improvement. It is understood that the style of the cooling fan ventilation cooling equipment can be said to be quite a lot. But the price of each type of chiller is different, and each material is different. What kind of material determines the price, this is beyond doubt.

The surface of the air cooler is mainly composed of a special fiber corrugated honeycomb wet curtain, a high-efficiency energy-saving fan, a water circulation system, a float valve hydration, a casing, and electrical components. When the fan is running, a negative pressure is generated in the cavity to make the air outside the machine. Flowing through the porous wet curtain surface forces the dry bulb temperature of the curtain air to drop to the wet bulb temperature close to the outside air, ie the dry bulb temperature at the exit of the cooler is 5-12 °C lower than the outdoor dry bulb temperature (dry heat region) Up to 15 ° C), the hotter the air, the greater the temperature difference, the better the cooling effect.

Cooling fan frequency conversion energy saving: energy saving is mainly reflected in the application of fans and pumps. In order to ensure the reliability of production, all kinds of production machinery have a certain margin when designing with power drive. When the motor can not be operated under full load, in addition to meeting the power drive requirements, the excess torque increases the consumption of active power, resulting in waste of electrical energy.

When using the air conditioner frequency control, if the flow demand is reduced, the speed can be satisfied by reducing the speed of the pump or fan.

After the above analysis, the quality of the chiller is so good, but the price has not been much improved, which ensures that consumers can guarantee the quality and quantity in purchasing this product. Therefore, it is recommended that you also go to a number of references when choosing an air cooler. Do not blindly see that the price is cheap to buy, and there may be different differences in function and function.
