Problems solved by technology

[0009] Therefore, the efficiency of the compressor decreases and the energy consumption increases
That is, as the temperature increases during the compression operation, the isentropic efficiency decreases and the energy consumption increases
[0010] In addition, since the sucked gas is located adjacent to the discharge chamber 73, the efficiency of the compressor decreases due to heating.
[0011] In addition, according to the conventional scroll compressor, when the degree of superheat of the compressor is reduced to improve the heat transfer efficiency of the evaporator (not shown in the figure), the sucked refrigerant that has not left the liquid state is compressed and wet-compressed, and finally the compressor suffers damage

Embodiment Construction

[0037] Refer below Figure 2 to Figure 5 A preferred embodiment of the present invention will be described in more detail.

[0038] As shown in the figure, the variable frequency scroll compressor 1000 of the present invention includes a casing 100, a suction port 600 and a discharge port 700 arranged in the casing 100, a pair of two meshes that are accommodated in the casing 100 and engaged with each other. Fixed scroll 810 and an orbiting scroll 820; a drive shaft 830; a motor 840; a motor 840 installed between the end of the drive shaft 830 and the orbiting scroll 820 to drive the orbiting scroll 820 to orbit ( and an anti-rotation mechanism 860 for preventing the orbiting scroll 820 from rotating, such as an Oldham ring. The driving shaft 830 , the motor 840 , the sliding sleeve 850 and the anti-rotation mechanism 860 constitute the orbiting motion driving part of the orbiting scroll 820 .

[0039] Such as figure 2 and Figure 4 As shown, the housing 100 includes a fr...

Abstract

The present invention relates to an inverter type scroll compressor and comprises a housing, a fixed scroll which is set up inside the housing, a swivel scroll which swivels around the fixed scroll, a driving unit which turns the swivel scroll, an intake port and a discharge port which are in the housing, and an inverter which faces the front surface of the fixed scroll. An intake hole penetrating to the compression chamber and a discharge hole are respectively formed in the fixed scroll and the swivel scroll. Accordingly, the present invention is configured so that coolant is discharged through the discharge hole after the coolant passes through the inverter and the fixed scroll and then flows into the compression chamber. Therefore, this prevents overheating of the compressor caused by the inverter and increases remarkably the efficiency of the compressor by cooling the inverter and a compressed coolant with additional coolant at the same time. Additionally, the power required for compression up to a certain pressure is saved.

Description

technical field [0001] The invention relates to a variable-frequency scroll compressor, in particular to a variable-frequency scroll compressor which uses sucked coolant to simultaneously cool a frequency converter and compressed coolant to reduce energy consumption and greatly improve efficiency. Background technique [0002] In general, a scroll compressor includes a fixed scroll having a volute and maintaining its fixed state even if a drive shaft rotates, and a revolving scroll having a volute and revolving when the drive shaft rotates. scroll piece. In such a scroll compressor, an orbiting scroll orbits along a fixed scroll and coolant is sucked into a compression chamber formed between the fixed scroll and the orbiting scroll, thereby compressing the coolant. [0003] figure 1 An example of such a scroll compressor (hereinafter referred to as "conventional scroll compressor") is shown. The following is the reference figure 1 A schematic illustration of this type of...
