The present invention relates to a combined vacuum extraction device of the absorption chiller (or cold and hot water dispenser).

Conventional extraction device is mainly applied mechanical manual extraction device using vacuum pimp and automatic extraction device using palladium (pd) cell, but mechanical manual extraction device is complicated structure of low chamber to condense underwater in non-condensable gas. The device cannot extract non-condensable gases other than hydrogen gas.

Therefore, the present invention combines a mechanical manual extraction device using a vacuum pump and an automatic extraction device using a palladium cell to extract hydrogen gas generated inside the refrigerator as an automatic extraction device, and to extract other non-condensable gases except hydrogen using a mechanical manual extraction device. It is intended to simplify the structure of the low chamber and to eliminate the frequent operation due to the conventional simple bleeding function, thereby reducing the cost of power.

The design consists of an automatic extraction system and a mechanical manual extraction system.

The automatic extraction system consists of absorption liquid chamber, cooling heat exchanger, siphon, non-condensing gas tank, and palladium cell. The mechanical manual extraction system is composed of control valve (Diaphragm valve), manometer actuator and vacuum pim.

Referring to the configuration and effect of the present invention in detail based on the accompanying drawings as follows.

1 to 3, the absorbent liquid storage chamber 4 of the automatic bleeding system is sent to the cooling heat exchanger 5 through the pipe at the bottom while maintaining the absorbent liquid sent from the absorbent liquid pump 7 at a constant level.

The cooling exchanger 5 has a coil pipe 15 connected to the absorbent liquid storage chamber 4, and a water pipe for supplying cold water into the cooling heat exchanger 5 is connected to one side of the absorption liquid storage chamber 15. Cold water flows to the outside and heat-exchanges to cool down the absorbing liquid and increase the absorbing power, thereby dropping it into the siphon 6 by a predetermined amount.

In the siphon 6, the absorbing liquid dropped from the cooling heat exchanger 5 absorbs the water group in the non-condensing gas and descends together with the remaining non-condensing gas.

The absorbing liquid descending from the siphon 6 is sent to the absorber 3, and the non-condensable gas is seen as a non-condensable gas tank 1 through the pipe.

In the non-condensable gas tank (1), the hydrogen cell of the non-condensable gas is extracted by using the metallic characteristic by heating the palladium cell 14 with the heater 13.

Here, the heater 13 is installed on the upper part of the paracell cell assembly 8 and the paradium cell 14 penetrates through the central part of the palladium cell assembly 8, and the palladium cell assembly 8 is a non-condensing gas tank. It is connected to one side of (1).

Here, the heater 13 is installed on the upper part of the paracell cell assembly 8 and the paradium cell 14 penetrates through the central part of the palladium cell assembly 8, and the palladium cell assembly 8 is a non-condensing gas tank. It is connected to one side of (1).

The remaining non-condensable gas, except for hydrogen gas, is operated by a vacuum pump 12 of a mechanical bleeding system connected to the non-condensable gas tank 1 by a pressure gauge 9, a manual control valve 10, an actuation trap 11, and the like. Will be added.

Reference numeral 2 is a low temperature regenerator.

The present invention is applicable to refrigeration equipment requiring vacuuming in an aircraft.

This paper composed of the above is the structure of the low chamber is simple, eliminates the causes of trouble and defects caused by the frequent operation of the vacuum pump to achieve a perfect bleeding effect, as well as to reduce the cost of power.
