Buffer and air-conditioner using same

A buffer and cavity technology, which is applied in the field of air conditioners with buffers, can solve the problems of strong vibration of the throttling part of the pipeline, aggravated the degree of eddy current and turbulent flow in the pipeline, and large fluctuation of pressure pulsation, so as to improve the flow rate. condition, reduce eddy current turbulence phenomenon, improve the effect of fixed frequency

Problems solved by technology

The actual situation often occurs: 1. The liquefaction of the refrigerant coming out of the condenser is not complete. The refrigerant with gas-liquid two-phase coexistence has large pressure fluctuations. 2. The refrigerant is at the junction of the differential device (filter) and the capillary, due to the sudden change in the cross-section of the pipeline and the rapid decrease in the pressure of the refrigerant, resulting in a burst of strong noise. Part of the refrigerant flashes (that is, produces cavitation), which intensifies the eddy and turbulent flow of the pipeline, and causes irregular strong vibration and disturbing noise at the variable diameter and throttling part of the pipeline.

Embodiment Construction

[0026] see figure 1 , the lower part of the buffer is connected to the air conditioner condenser through an L-shaped tube 9, and the upper part is connected to the differential device 2 through a 30 mm long copper tube with an outer diameter of 7 mm. The tubes are eventually connected to the evaporator, the evaporator is connected to the compressor by the return gas pipe, and the compressor discharge pipe is connected to the condenser.

[0027] When the air conditioner is working, under the forced push of the compressor, the high-temperature and high-pressure refrigerant gas enters the condenser, and is forced to cool by the fan, and the cooled liquid refrigerant is released from the condenser. figure 1 The L-shaped tube 9 shown in the figure enters the buffer, and after the buffering effect, the refrigerant flows smoothly, and then enters the capillary tube 1 through the differential device 2, and the throttling and step-down refrigerant enters the evaporator from the liquid ...

Abstract

The invention relates to a buffer, which comprises a main body, a cover plate and a porous cylindrical piece. Screw holes are arranged at two ends of the main body, a cavity provided with an opening end is arranged in the middle of the main body, the opening end of the cavity is sealed by the cover plate, the cover plate is provided with a cylindrical end, and the porous cylindrical piece is sleeved on the cylindrical end which is provided with a pressure relief hole. The buffer is connected between a condenser and a differentiator of an air-conditioner to buffer pressure pulse of the gas phase and the liquid phase to reduce vortex and turbulent flow. The transition effect of the buffer damages conditions of refrigerants to produce cavitation as far as possible, the solid frequency of a capillary assembly is changed by adding the buffer, so that the buffer can avoid resonance frequency and reduce vibration and noise of the capillary assembly, and finally abnormal grunting sound and harsh fluttering sound in startup, shutdown and the operation process of the air-conditioner can be removed.

Description

【Technical field】 [0001] The invention relates to the field of air conditioners, in particular to an air conditioner provided with a buffer. 【Background technique】 [0002] In the existing split-type air conditioner, the refrigerant flows out from the condenser, passes through the differential device (filter), passes through the capillary tube, and then is sent to the evaporator by the liquid delivery pipe. The actual situation often occurs: 1. The liquefaction of the refrigerant coming out of the condenser is not complete. The refrigerant with gas-liquid two-phase coexistence has large pressure fluctuations. 2. The refrigerant is at the junction of the differential device (filter) and the capillary, due to the sudden change in the cross-section of the pipeline and the rapid decrease in the pressure of the refrigerant, resulting in a burst of strong noise. Part of the refrigerant flashes (that is, produces cavitation), which intensifies the eddy and turbulent flow of the pi...
