Title:
EJECTOR AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/184828
Kind Code:
A1
Abstract:
An ejector (10), comprising: an inlet section (11), the inlet section (11) being connected to a liquid separator (20); an outlet section (17), the outlet section (17) being connected to an indoor heat exchanger (30); and a resistance silencing chamber (14), the resistance silencing chamber (14) being formed between the inlet section (11) and the outlet section (17), and the cross-sectional area of the resistance silencing chamber (14) being larger than that of the inlet section (11). Moreover, further provided is an air conditioning device using the ejector. According to the provided ejector (10), the cross-sectional area of the resistance silencing chamber (14) is abruptly changed with respect to the inlet section (11), noise generated by a gas-liquid two-phase refrigerant causes impedance change in a propagation process to generate reflection and interference of acoustic energy, such that acoustic energy radiated outwards by the resistance silencing chamber (14), that is, the whole ejector, is reduced, thereby achieving the purpose of silencing, users on the indoor side are not subjected to interference, and the comfort of use of the whole product is improved. The provided ejector (10) is both a thermodynamic throttling device and a mechanical vibration noise reduction device, and has two functions.
