Problems solved by technology

[0006] There are solid impurities called pollutants in the refrigerant flow, so the impurities clog the throttle passage during long-term use, causing a problem that the refrigerant flow rate of the throttle valve device changes.
For this reason, in long-term use, it is difficult to obtain stable dehumidification performance

Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] figure 1 Embodiment 1 of the throttle valve device 10 of the present invention is shown.

[0033] The throttle device 10 has a valve housing 11 made of metal. The valve casing 11 encloses the first inlet and outlet hole 12, the second inlet and outlet hole 13, the valve chamber 14 that is often directly connected with the first inlet and outlet hole 12, and the valve between the valve chamber 14 and the second inlet and outlet hole 13. Hole 15. A valve seat portion 16 is formed around an opening end of an example of the valve chamber 14 of the valve hole 15 .

[0034]A valve body 17 is provided in the valve chamber 14 so as to be movable in the vertical direction (valve lifting direction) in the drawing. The valve body 17 can move between the valve closing position and the valve opening position. In the valve closing position, the valve seat p...

Abstract

The objective of this invention is to significantly reduce noise caused by the intermittent expansion burst of gas particles (gas blocks) after passing through an orifice by preventing the gas particles from being enlarged in the throttle valve device. A passage that guides fluid to the throttle passage member 23 from a filter element 20 for capturing an impure ingredient is provided by a distributed communicating hole 26 of a plurality of small paths.

Description

technical field [0001] The present invention relates to a throttle device and an air conditioner, and more particularly to a throttle device and an air conditioner used as a throttle valve for dehumidification in an air conditioner having a dehumidification mode. Background technique [0002] As an air conditioner capable of dehumidification operation, there is known an air conditioner with a dehumidification function in which the indoor heat exchanger is divided into two parts, and a throttle valve is provided between the two indoor heat exchangers in a closed state. The throttle valve device (throttle valve for dehumidification, circulation dry valve), during dehumidification operation, the refrigerant flows in the throttle passage of the throttle valve device that closes the valve and acts as a throttle valve, so that the refrigerant that is divided into two parts Among the indoor heat exchangers, the upstream indoor heat exchanger acts as a condenser, and the downstream ...
