What should be paid attention to when using air refrigeration compressors

What should be paid attention to when using air refrigeration compressors Air compressor is a kind of equipment that is often used in refrigeration equipment. It converts electrical energy into mechanical energy and compresses low-temperature and low-pressure gas refrigerant into high-temperature and high-pressure gas to ensure the refrigeration cycle. In the process of manufacturing and daily use of air-cooled compressors, there are many points that should be noted.    Refrigeration compressors are used in refrigeration systems. There are mainly two types of rotary and reciprocating pistons, which belong to positive displacement air compressors. The rotary type mainly relies on the rotary motion of the rotary body to change the working volume of the cylinder, and can be classified again. For example, the screw type air compressor: the cooling capacity is about 100 to 1200KW, which can be used in large and medium-sized air conditioners and refrigeration equipment. Rolling rotor air compressor: The cooling capacity is about 8~12KW, which is mostly used in small air conditioners and refrigeration equipment. Scroll air compressor: The cooling capacity is about 8 ~ 150KW, which is mostly used in small and medium-sized air conditioners and refrigeration equipment.   Reciprocating piston type mainly relies on the reciprocating motion of the piston to change the working volume of the cylinder to achieve the purpose of compressing gas. Judging from the internal structure, it can be divided into three categories. The first is the open type. This type of mechanism is relatively complicated and bulky, and it is relatively stable to work, but it is currently being eliminated. The second type is semi-enclosed, with long use time and strong cooling capacity, but the noise is relatively large and is used in many refrigeration equipment. The third type is fully enclosed, compact in structure, good in sealing performance, low in noise, but low in power, difficult to maintain, and used in air conditioners.    Air compressors are used in refrigeration systems. Note that the refrigerant cannot enter the compressor. The refrigerant should be injected into the air-conditioning system from the rear of the condenser. In addition, during use, excessive refrigerant cannot be added to the compressor, which may cause the liquid refrigerant to be directly sucked into the compressor, resulting in damage to the compressor due to the incompressibility of the liquid.    Air compressors are now commonly used in refrigeration systems. When users specifically choose to use them, they need to pay more attention. Especially when using it in daily life, pay attention to the leakage of refrigerant. When adding refrigerant, you need to ask professional staff to do this work. Be careful to add more or less, which affects the normal work.
