Scroll compressor and air conditioner including the scroll compressor

Abstract

A scroll compressor and an air conditioner including a scroll compressor are provided. The scroll compressor may include a main frame configured to support an upper portion of a rotating shaft; a fixed scroll coupled to the main frame and having a first wrap; an orbiting scroll provided to perform an orbiting motion with respect to the fixed scroll and having a second wrap which forms a plurality of compressions chamber between the first wrap and the second wrap; a suction port configured to enable a first refrigerant to be suctioned into the compression chamber; a first introduction port provided at a first side of the fixed scroll and configured to inject the first refrigerant into the plurality of compression chambers; a second introduction port provided at a second side of the fixed scroll and configured to inject a second refrigerant having a pressure different from a pressure of the first refrigerant into the plurality of compression chambers; and a third introduction port provided at a third side of the fixed scroll and configured to inject a third refrigerant having a pressure different from the pressure of the first refrigerant and the second refrigerant into the compression chamber. The first introduction port may be provided at a position at which injecting of the refrigerant through the first introduction port is able to be performed before suctioning of the refrigerant through the suction port is completed.

Description

technical field [0001] The invention relates to a scroll compressor and an air conditioner including the scroll compressor. Background technique [0002] An air conditioner is a home appliance that keeps the indoor air in an optimum state according to its use and purpose. For example, the room is adjusted to a cool cooling state in summer, and a warm heating state in winter, and the indoor humidity is adjusted to adjust the indoor air to a comfortable and clean state. [0003] In detail, the air conditioner drives a refrigeration cycle for performing compression, condensation, expansion, and evaporation processes of refrigerant, thereby enabling cooling or heating operation of an indoor space. Such an air conditioner can be classified into a separate type air conditioner in which the indoor unit and the outdoor unit are separated, and an integrated air conditioner in which the indoor unit and the outdoor unit are combined into one device, depending on whether the indoor uni...

Problems solved by technology

[0009] As another example, when the injection hole is formed at another predetermined position, and the injection of the refrigerant is performed too late after the suction of the refrigerant in the scroll compressor is completed, due to the internal pressure of the compression chamber If the injection is performed after it has risen, the problem of reduced injection flow may occur
