Problems solved by technology

[0002] At present, the following problems exist in the air-conditioning rotary compressor: when the exhaust pipe of the compressor is blocked during the operation of the compressor, and the heat exchanger is poorly dissipated, the pressure in the compressor shell rises sharply, causing abnormal wear of the parts; when the refrigerant leaks , the electronic expansion valve is opened too small and the suction pressure is too low when the suction pressure is too low, the pressure difference between the suction and discharge of the compressor will increase, the running resistance will increase, the current will rise, and the internal temperature will increase, resulting in frequent protection by the overload protector and frequent startup of the compressor, resulting in The discontinuous operation of the compressor may easily cause damage to the compressor components and reduce the life of the compressor

Embodiment 2

[0029] The difference between the rotary compressor of the second embodiment and the first embodiment is that a pressure regulating valve is added. Specifically, in Embodiment 2, the pressure control device further includes a pressure regulating valve, including a fourth air inlet and a fourth exhaust port, the fourth air inlet and the fourth exhaust port have a connected passage state and a corresponding In the off-circuit state of blocking, the fourth exhaust port communicates with the first air intake port 21 . The structure of the pressure regulating valve is the same as that of the pressure relief valve 30 , the fourth air inlet is equivalent to the second air inlet 31 , and the fourth air outlet is equivalent to the second air outlet 32 ​​. Even if the relief valve 30 fails, the rotary compressor of the second embodiment can prevent the suction pressure of the compression cylinder from being too low.

[0030] The application provides an air conditioner, such as Figure...

Abstract

The invention provides a rotary compressor and an air conditioner with the same. The rotary compressor comprises a shell (10), a compression cylinder and a pressure control device, wherein the shell comprises a first accommodating cavity; the compression cylinder is arranged in a first accommodating cavity, and comprises a cylinder body (20); the cylinder body (20) comprises a first air inlet (21) and a first exhaust opening; the pressure control device comprises a pressure release valve (30); the pressure release valve (30) comprises a second air inlet (31) and a second exhaust opening (32); the first air inlet (31) is communicated with the first exhaust opening; the second exhaust opening (32) is communicated with the first air inlet (21); and the second air inlet (31) and the second exhaust opening (32) have a communicated on-state and a blocked off-state. According to the rotary compressor, over-high exhaust pressure of the compression cylinder is prevented.
