Scroll compressor and air conditioner including the same

Abstract

The scroll compressor includes a fixed scroll including a first wrap, an orbiting scroll disposed to have a phase difference with respect to the fixed scroll, the orbiting scroll including a second wrap defining a compression chamber together with the first wrap, a suction part to receive a refrigerant into the compressor chamber, a driving shaft to transmit a rotation force to the orbiting scroll, a first injection part disposed in one position of the fixed scroll to introduce a refrigerant into the compression chamber, and a second injection part disposed in another position of the fixed scroll to introduce a refrigerant into the compression chamber, where the second wrap is disposed on the orbiting scroll such that the first injection part is opened to introduce the second refrigerant before the receipt of the first refrigerant through the suction part is completed during the orbiting of the orbiting scroll.

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 maintains indoor air to a desired state according to its use and purpose. For example, such an air conditioner controls indoor air to a cooler state in summer and controls indoor air to a warmer state in winter. In addition, the air conditioner controls the humidity of indoor air and purifies the indoor air so that the air becomes a comfortable and clean state. [0003] In detail, the air conditioner has a refrigerant circulation system in which compression, condensation, expansion, and evaporation processes of refrigerant are performed. Accordingly, a cooling or heating operation of the air conditioner may be performed to cool or heat indoor air according to a cooling cycle. [0004] According to whether the indoor unit and the outdoor unit are separated from each other, this ...

Problems solved by technology

In this case, there arises a disadvantage that the manufacturing cost or installation cost of the air conditioner increases

[0012] In addition, when the refrigerant discharged from the condenser is expected to be in a subcooled state, that is, when a subcooled refrigerant is required, although the evaporation performance of the evaporator, that is, the area under the straight line connecting point "d" to point "a" can be increased, it is difficult to guarantee Image 6 Subcooling of the refrigerant in the system

Therefore, it is difficult to expect improvement in performance
