Q:How can I check the refrigerator for copper tubes, aluminum tubes or iron pipes?
From the compressor outlet to dry filter high pressure section, a condenser, a dew proof tube, filter composed of high pressure pipe, the high pressure section is from capillary tube; to press the return pipe low pressure, low pressure with capillary, evaporator, an air return pipe, capillary and return tube are used for copper pipe, evaporator aluminum and iron, but the economic crisis since the price of copper fell, some manufacturers in order to improve product quality and increase the selling point, but also the use of copper tube evaporator, refrigeration evaporator mounted in the installed freezer, said separating rack, plastic drawer on the shelf, you can try to remove Pakistan drawer, copper general refrigeration evaporator buried device in a cabinet, we cannot see.Since you bought it, you really don't need to know much about it.
Q:What brand of refrigerator is copper pipe now?
There are no brands of refrigerators all in copper tubes.Generally, it is a refrigeration pipe system composed of copper tubes, aluminum tubes and Bondi tubes, which can meet the daily needs.
Q:Why is the air conditioning copper tube again become "air conditioning purple copper tube"?
The use of air conditioning is also called copper copper copper or copper
Q:Air conditioning copper tube packaging broken after being soaked in rain on air-conditioning?
Hanging insulation pipe, a general 1.8 meters, retail 2 to 3 yuan a, 1.5p is small, is 6, big is generally 12. The price is about the same. The bandage is 1.5 to 3 yuan. One roll can be used to wrap the wall air conditioner standard tube completely. Bandage with broken cotton insulation is very vulnerable to ultraviolet damage, within a year powdering, air-conditioning power loss increased. Affect machine life. Hope to help you.
Q:The brass of 42 to 6.4 of each pipe diameter approximately every 100 meters?
Copper tube is also called copper tube. A tube of non-ferrous metal that is a pressed and drawn seamless tube.
Q:How can the air conditioner copper pipe burst?
Looking for professional maintenance master, door-to-door service: broken, you can change the copper pipe, or directly weld the gap...
Q:Who can explain the meaning of ACR copper tube to me in detail? Thank you 30
Application and development of ACR copper tube in air conditioning heat exchangerDu Xuefeng, Zhang Xiaochun, Wang Yankun, Li JinweiAbstract: This paper introduces the ACR tube heat exchanger in air conditioning, and the causes of the evaporator and heat exchanger with copper in the process of easy problems, principle and manufacturing technology of high cleanliness and high efficiency tube tube on behalf of the development direction of future rifled tubes are discussed.Key words: air conditioning; heat exchanger; internal screw copper tube; energy efficiency ratio; tooth profile
Q:Air conditioning copper tube can hold several meters longest
Different types and different sizes of air conditioners can connect different lengths of copper tubes.
Q:The air conditioner is not cool cool thin copper thick pipe room is going on is not cold air compressor bad again
This is obviously a lack of refrigerantFirst of all, to ensure that indoor and outdoor cleaning, ventilation smooth, but also to ensure that the normal work of air-conditioning basic conditions, including indoor filter screen, outdoor fins clean. Recommend cleaning at least 2 times a year, according to the use of it!In fact, air conditioning refrigeration is not good or not refrigeration, not necessarily is the lack of refrigerant, in the air quality is no problem, installed in place, the air-conditioning used more than the design life will not be lack of refrigerant.As a non professional, how to simply determine whether the air conditioning is lack of refrigerant, then observe and touch the outdoor machine, high and low pressure valve, frost situation and temperature bar.1, under normal circumstances, high pressure valve drying, and there is a certain Yu Wen (long working in refrigeration, there will be a small amount of condensate), low pressure valve moist and water dew, water dew according to the weather conditions.2, high pressure valve drying (long working in the refrigeration state, there will be a small amount of condensate), low pressure valve frosting, which is the lack of refrigerant.3, high pressure valve frosting, low pressure valve is frosted or dry, that is serious lack of refrigerant or system micro plug.4, high pressure valve drying is not cool, low pressure valve drying is not cool, the system is seriously leaking, or compressor does not work.
Q:About the influence of air conditioning copper tube too long?
As far as the air conditioning copper pipe is concerned, the pipeline shall not be longer than 15 meters, otherwise the refrigeration effect of the air conditioning connecting pipe will be greatly reduced, and even the refrigeration effect of the air conditioning connecting pipe can hardly be obtained. In serious cases, it may cause overloading of the body until serious damage occurs.Encountered in the actual cannot but in design and construction, air conditioning, brass 15 meters above, will need to increase the cooling capacity, a 1.5 horsepower, the cooling effect will be affected. According to the manufacturing theory of air conditioner, if the air conditioning connecting pipe is too long, it is easy to produce too much load, and it is easy to appear the problem of compressor returning oil, which will affect the service life of the compressor.Therefore, the manufacturers in order to avoid unnecessary loss of consumers do not want to lengthen the construction unit of the air conditioner copper pipe is too long, too long not only affect the air conditioning pipe, cooling effect, but also affect the service life of the refrigeration system.
