Air conditioning units

Abstract

The invention provides an air conditioning unit. The air conditioning unit comprises an outdoor main case. A compressor and a condenser are collected inside the outdoor main case. A fixed device which is connected with the connecting portion of an exhaust pipe and an inlet pipe of the condenser is arranged inside the outdoor main case. The fixed device comprises a base arranged on the outdoor main case, a connecting ring which surrounds the exhaust pipe and is tightly attached to the exhaust pipe and a bolt, wherein one end of the blot is fastened with the base, and the other end of the bolt is connected with the connecting ring. By additionally arranging the fixed device, the partial vibration of the exhaust pipe can be transmitted to the outdoor main case or collected by other components inside the main case. The vibration generated when the compressor is started or shut down, and an air condition is in use can be blocked or receded in maximum. The tubing fracture and welding spot cracking which are caused by the pipeline fatigue due to the fact that tubing connected with the exhaust pipe vibrates in long-time can be avoided.

Description

technical field [0001] The present invention refers to an air conditioning unit. Background technique [0002] The telecommunication base station or computer room air conditioners that operate cooling throughout the year are generally single-cooling split air conditioners. This type of air conditioner runs for a long time throughout the year, especially at the turn of spring and summer or summer and autumn. The air conditioner can reach the indoor set temperature after a short period of operation, so the compressor starts and stops frequently. Due to the large vibration amplitude when the compressor starts and stops, the suction and discharge pipes of the compressor vibrate violently. Specifically: when the compressor is installed in the outdoor unit, the compressor discharge pipe is directly connected to the condenser inlet pipe. , the vibration of the compressor discharge pipe drives the condenser inlet pipe to vibrate at the same time; when the compressor is installed in...

AI Technical Summary

Problems solved by technology

The long-term vibration of compressor suction and exhaust pipes, condenser inlet pipes, and evaporator outlet header pipes leads to fatigue of the pipes connected to them, resulting in solder joint cracks or pipe breaks, which easily lead to refrigerant leakage

A small amount of refrigerant leakage may lead to high discharge temperature of the compressor and a decrease in cooling capacity; a large amount of refrigerant and compressor oil leakage for a long time may cause the compressor to stop due to low pressure alarm, and multiple refrigerant leakage may lead to poor internal lubrication of the compressor and compression machine parts damaged

[0003] The traditional damping method is mainly by optimizing the pipeline design and adding damping blocks on the pipeline. This method is effective in reducing the piping vibration when the compressor is running normally, but it cannot solve the large vibration when the compressor starts and stops.
