Frequently Asked Questions
1. What is a mobile air conditioner?
Answer: first of all, industrial air conditioners are not air coolers. They do not need to add water. They use the same refrigeration principle as air conditioners. They produce cold air with a temperature difference of 10-15 ℃ instead of cold air with humidity. Secondly, the industrial air conditioner is not a traditional air conditioner. It is easy to move, plug in and play, and can adapt to the high temperature below 45 ℃. Mobile industrial air conditioner is a kind of portable and integrated post refrigeration equipment which adopts compressor and heat exchanger system for heat exchange and refrigeration, and is suitable for industrial and outdoor environment.
2. Question: what is the difference between mobile industrial air conditioner and water curtain air conditioner?
Answer: ① the air blown by the water cooling fan only has a temperature difference of 4 ℃ - 5 ℃. It has no obvious effect at high temperature, and the cooling effect is poor, which can not fundamentally solve the problem of high temperature heatstroke; while the industrial mobile air conditioner blows out the air conditioning air with a temperature difference of 10 ℃ - 15 ℃, which can play a good cooling effect on the operators in summer
② The water cooling fan has humidification effect, which can not be used in some places, especially in the cooling of mechanical manufacturing and cabinet electronic control part. At the same time, the increase of humidity will breed bacteria in the environment, which is harmful to human body.
③ In addition to the normal power consumption, the use of water cooling fan also needs to cooperate with water addition, which has a high cost. Moreover, the use of water curtain cooling fan needs to cooperate with the engineering installation, so the initial investment cost is not low.
3. Q: how much space can industrial mobile air conditioners be used in?
Answer: the industrial mobile air conditioner is different from the ordinary household air conditioner. It is used in the open space for point cooling. It can not conduct the overall cooling of internal circulation, so it is impossible to estimate the area. General industrial mobile air conditioners are purchased according to the number of posts or the number of areas requiring point cooling.
4. Q: what is the difference between industrial mobile air conditioner and general household mobile air conditioner?
Answer: ① the appearance is made of sheet metal, which is more durable and can withstand the corrosion of oil and dust in industrial environment.
② It can adapt to the high temperature environment below 45 ℃, and the general household mobile air conditioner will stop working at 35 ℃.
③ The air outlet is a flexible hose, and the length and angle of the air outlet can be adjusted arbitrarily according to the use environment.
④ The integral filter screen and panel can be removed, which is more convenient for cleaning and maintenance of the machine.
5. Q: what is the cause of frosting on the evaporator after the air conditioner has been used for a period of time?
A: there are two main reasons for frosting: first, the cold air is not smooth. The length of the cold air extension pipe should not exceed 3 meters to avoid right angle bending, or to reduce the diameter of the cold air pipe, or to block the air outlet, or to transport cold air to the inside of the equipment. If the internal volume of the equipment is relatively small, the output cold air will accumulate at the air outlet so as not to be transported out in a hurry and cause frosting of the evaporator; secondly, the ambient temperature of the machine is low. The normal working environment temperature of the machine is 18 ℃ - 45 ℃. When the temperature is lower than 18 ℃, the evaporator of the machine is prone to frost.
6. Q: after the air conditioner has been used for a period of time, the air volume has become smaller. What is the cause?
If the air inlet is small, check whether the air inlet of the variable air volume is small, and check whether the air inlet and outlet of the motor are blocked.
7. Q: what is the cause of water leakage of air conditioner?
Answer: air conditioner water leakage phenomenon can check whether the water storage bucket is placed in place; check whether the water outlet pipe is unblocked; check whether the water collecting plate is dirty, blocked or cracked, and the above reasons will cause water leakage; the leakage phenomenon of the model without water storage bucket may be caused by the condensation on the sheet metal parts.
8. Q: how to clean the heat exchanger?
Answer: the heat exchanger should be cleaned in time when dirty and blocked. High pressure air or water can be used to blow along the aluminum plate direction of heat exchanger. When it is particularly greasy, you can use soapy water toothbrush to brush up and down the aluminum sheet. It is not allowed to brush horizontally, otherwise the aluminum sheet will fall down and affect the cold and heat exchange
9. Q: what is the cause of condensation on the outlet duct?
Answer: the air conditioner is not smooth, and the cold air accumulates at the air outlet, and the cold air pipe will be dewed
10. Q: can air conditioners use circulating air?
Answer: the machine with exhaust hot air pipe can extend the heat exhaust pipe to the outdoor (Note: extend the exhaust air pipe no more than 3 meters, avoid right angle bend, ensure smooth exhaust air), the machine inlet and outlet are in the same space; the machine with separate inlet and outlet duct can put the inlet and outlet duct in the same space for cycle refrigeration.
11. Q: what should be paid attention to when using extended power cord for air conditioner?
Answer: professional electricians are required to operate the extended power cord. Refer to the power cord connection requirements in the manual, and correctly select the length and diameter of the power cord.
12. Question: what are the wiring precautions of the three-phase air conditioner?
Answer: the wiring of the three-phase air conditioner should be operated by professional electrician. The power line should be connected to the specified terminal. The length and diameter of the power line should be in accordance with the requirements of the manual.
13. Q: what are the reasons why the three-phase air conditioner does not start after starting up, or will stop automatically after starting?
A: if you don't start it after starting up, you can check whether the power supply is correct, whether the wiring is reliable, and whether the phase is correct. You can check the fault display of the fault indicator light on the electric control panel and the fault indication code table in the manual. The machine will shut down automatically after startup, which may be caused by the high ambient temperature of the machine or the serious blockage of the condenser, and part of the reason is caused by refrigerant leakage or compressor damage.
14. Can the machine be controlled remotely?
Answer: as long as the switch lead is extended, pay attention to the reliable connection of the outgoing line, and the length of the extended switch lead is matched with the wire diameter.
15. Q: what are the requirements for the ambient temperature of the air conditioner?
Answer: the ambient temperature of air conditioner is 18 ℃ - 45 ℃. When the temperature is lower than 18 ℃, the air conditioner is prone to frost, and when the temperature is higher than 45 ℃, the compressor will reappear the overheating protection.
16. Q: what is the reason why the air conditioner doesn't work?
Answer: do not refrigerate, first check whether the power supply is correct and stable; if you use the extended power line, check whether the length of the power line matches the diameter of the line; if the ambient temperature is too high or the inlet and outlet air is blocked, causing overheating protection of the compressor; secondly, check whether the capacitor of the compressor is damaged, and whether the connecting ends inside the machine are firm and reliable; finally, check whether the temperature protector on the compressor is damaged Whether the compressor is damaged or not.
17. Q: what should be paid attention to when the air conditioner is placed and stored?
Answer: the air conditioner should be placed in a flat place. It is forbidden to put it on the slope, uneven floor, entrance and exit of the house. It should not be placed in the place with rain, snow and wet water, volatile liquid gas such as volatile, diluent, gasoline, kerosene, liquefied gas, aluminum, magnesium, lead and other dust places. When the air conditioner is stored, the accumulated water should be poured out and stored after the water storage bucket is dry; the air conditioner should not be stored horizontally or upside down; it should not be stored in places with high humidity, direct sunlight and rain splashing.
18. Question: what problems should be paid attention to when using the extended duct?
Answer: when using the extended cold and hot air pipe, please do not exceed 3 meters to avoid right angle bend and ensure smooth air outlet.
