Problems solved by technology

[0007] Under the above circumstances, the thermal management of the above two compressors has the following problems: under the extreme conditions of low evaporating temperature and high condensing temperature, the cooling of the moving parts such as the motor is insufficient, and it is easy to cause the refrigerant to be heated by the moving parts. And cause suction overheating, affect the volumetric efficiency

Embodiment Construction

[0045] The following description of the preferred embodiments is exemplary only, and in no way limits the invention, its application or usage.

[0046] figure 1 An example of a known low pressure side scroll compressor is shown in cross section through the intake and exhaust ports. like figure 1 As shown, the low-pressure side scroll compressor 1 is a vertical compressor, which mainly includes: a casing 10 , a rotating shaft 20 , a motor 30 and a scroll mechanism 40 , which are described in detail below.

[0047] A partition 12 is provided in the housing 10 to partition the inner space of the housing 10 into a low pressure region (space below the partition 12 ) and a high pressure region (space above the partition 12 ). For the low pressure side compressor 1, both the motor 30 and the scroll mechanism 40 are accommodated in the low pressure region. The housing is provided with an air inlet 14 and an air outlet 16 for sucking in the refrigerant and discharging the compressed...

Abstract

The invention relates to a scroll compressor (200). The scroll compressor comprises a shell (210), a rotating shaft (220), a motor (230), and a scroll mechanism (240) driven by the motor through the rotating shaft, wherein an oil pool (218) is defined in the shell. The scroll compressor further comprises cooling parts (250, 280, 290a) for cooling the oil pool; and the cooling parts allow cooling fluids from the external of the shell to flow through the cooling parts. The scroll compressor can improve the heat management thereof, reduces the inspiration superheat degree, and improves cooling on movable parts, in particular the motor.

Description

technical field [0001] The present invention relates to a scroll compressor and a compressor system including the scroll compressor. Background technique [0002] This section is intended to provide background related to the present disclosure, which is not necessarily prior art. [0003] Commonly used compressor systems include refrigeration systems (for example, for refrigeration air conditioners / refrigerators, etc.) and heat pump systems (for example, for heating air conditioners / hot water units for winter heating, etc.). A compressor system typically includes a compressor, a condenser, a throttling device, and an evaporator, which are connected in sequence to form a refrigerant circuit. Among them, scroll compressors are often used as compressors. [0004] A scroll compressor generally includes: a casing; a rotating shaft; a motor including a stator fixed to the casing and a rotor fixed to the rotating shaft; and a scroll mechanism that is driven by the rotating shaft ...
