Problems solved by technology

Although this patented technology reveals some basic principles about how to realize the auxiliary air intake hole on the fixed plate of the scroll compressor, it does not point out the influence of the specific position of the auxiliary air intake hole on the system performance, and does not point out the optimal auxiliary air intake hole. area of ​​air intake
[0005] Since the profiles of different scroll compressors are very different, and the traditional system simulation method is too rough to reveal the essential characteristics of the scroll compressor's working process, the optimal scroll compressor auxiliary process has been studied for a long time. The position of the gas port, the theoretical and experimental test results cannot be unified

Embodiment Construction

[0028] see figure 1 , a method for determining the position of the air supply hole of a scroll compressor with an air supply circuit, mainly comprising the following steps: 1) the farthest end of the scroll profile on the fixed scroll of the scroll compressor on the side of the center of the circle Point M moves 360° to the center of the circle to obtain point A on the fixed scroll; 2) Make a straight line through point O and point A at the center of the fixed scroll to intersect the scroll line on the fixed scroll to obtain B 3) Rotate the straight line AB between point A and point B counterclockwise by 30° to obtain straight line A'B', which intersects the molded line on the scroll at point A' and point B'; 4) When the profile line of the movable scroll of the scroll compressor is in a position symmetrical to the center of the profile line of the fixed scroll, the line AB intersects with the profile line of the movable scroll or the profile line of the sealing ring to obtain...

Abstract

A method of determining gas supply hole position for vortex compressor having gas supply loop belonging to air condition compressor technology. The position of two symmetrical gas supply holes is determined through measuring series of position in fixed vortex rotary disc and moveable vortex rotary disc.

Description

technical field [0001] The invention relates to a method for determining the optimum air supply hole area of ​​a scroll compressor for a heat pump. Background technique [0002] In the current technology, the use of ordinary fixed-speed air source heat pumps has very large limitations, and the output of the heat pump is directly determined by the ambient temperature. Taking heating as an example, when the ambient temperature is high, the heat consumption of the building is relatively low, but at this time the output of the fixed-speed air source heat pump is at a relatively high level. When the ambient temperature drops, the heat demand of the building rises, but the output of the air source heat pump decreases rapidly with the drop of the ambient temperature, so the fixed speed air source heat pump cannot meet the load requirements of the building in a wide range. [0003] With the emergence of scroll compressors, in the early 1980s, Hitachi developed a scroll compressor a...
