Description

[Detailed description of the invention] The present invention relates to a degassing device for an absorption chiller/heater.

Conventionally, the degassing device of this kind of absorption chiller/heater has the absorption Il! After cooling the non-condensable gas stagnant in the absorber into the bleed tank by cooling it with cold water and lowering the vapor pressure in the bleed tank to the pressure in the absorber, It is customary to remove external carbon dioxide, which inevitably leads to a decrease in the capacity of the absorption cold/hot water tank.The present invention has a configuration in which cooling is performed with concentrated liquid T's liquid that is dripped at the inside of the bleed tank. The purpose is to remove non-condensable gases while maintaining a predetermined capacity of the absorption chiller/heater.

An embodiment of the present invention t' m * t:: will be crystallized and explained below.

The absorption chiller/heater has a regenerator (1) (2), a condenser (plow), and an evaporator (4).

It has a basic structure in which an absorber (group, heat exchanger m1 (6) ff), a water heater (8J) are connected with airtight piping, and a regenerator (1).
The refrigerant vaporized and separated in (2) is liquefied by dissipating heat in the condenser, and is led to the liquid refrigerant evaporator (4) where it is vaporized in the cough machine to work the cooling function and sequentially absorb the gaseous refrigerant. While absorbing the coolant in the cooling liquid in the vessel (5), the diluted liquid that absorbed the refrigerant is transferred back to the cooling vessel (1) (ironi), which heats and separates the refrigerant and regenerates the steamed liquid. As shown by the solid line arrow, the absorption liquid is distributed in the high temperature regenerator (1), the intermediate liquid pipe (9), the high temperature heat exchanger (6), the intermediate liquid pipe a, the low temperature regenerator (2), Fresh liquid arm (1M, low temperature heat exchanger (7) II liquid spray tube 13.
Absorption 1t (5), tank liquid pump 0. Dilute liquid van, low temperature heat exchanger (7), tank liquid pipe, high temperature heat exchanger (6), tank liquid pipe ast' flow sequentially and return to high temperature regenerator (1) (double main absorption liquid circulation path ( 1'D and the tank liquid pipe I constitute a sovereign liquid pipe line that communicates with the tank liquid pipe I.

The wire indicated by the broken line arrow is a side route from the vortex liquid pipe mouth of the generated absorption liquid circulation path to the air bleed tank ■, gas separation tank 0, and return pipe (
In another sub-absorption liquid circulation path, the concentrated liquid flowing through this circulation path returns to the absorption illumination reservoir of the LL collector through c).
(to) be dripped into the air bleed pipe (cnt')
Gaseous refrigerant is selectively absorbed from the gas in the introduced absorber (5), and the gas separation tank is 12 m & 2 downstream via the gas-liquid heating conduit C; 4) The remaining non-condensable gas is passed through the gas separation tank 3 in the form of bubbles. The bubbles flowing down through the conduit rise to the top and reach the upper space (double). When the non-condensable gas reaches a certain amount or more, the bleed pump (4t) is activated and discharged to the outside of the machine.

Next step; (to) the tank liquid 1rtte of the sovereign liquid pipe makes a side route and passes through the vJ sleeve air tank (7) to the tank liquid pipe - or tLe or intermediate liquid pipe 11: Returns the sub-tank liquid In the pipe, the sensible heat of the high-temperature concentrated liquid that is dripped into the bleed tank with the low-temperature concentrated liquid flowing through the snowy path, and the absorption heat generated when the concentrated liquid selectively absorbs the gaseous refrigerant, The vapor pressure in the bleed tank (7) is maintained lower than the vapor pressure in the absorber (5).

For example, the temperature at which two drops of C are applied in the bleed tank (7) is 46°C.

Temperature 6 at which the concentrated liquid with a sea degree of 655-5 flows through the sub-tank liquid pipe (to)
Heat exchanged with the tank liquid at 7℃ and concentration 5 & 5-, and the tank liquid was heated to 40℃.
When the temperature is increased by C2, the m solution is diluted, and the temperature is decreased by 45℃, the pressure in the extraction tank (A) is approximately 5.53E1m.
It becomes Hg. In this case, the pressure inside the absorber (5) is approximately 6
mmHg, the non-condensable gas in the absorber (5) is introduced into the bleed tank through the bleed pipe.

In addition, the absorption liquid in the gas separation tank ■υ flows through the return ttn to the liquid reservoir Cj34 of the absorber, and then flows through the tank liquid pump 13 (2) again through the main absorption liquid pipe. The flowing tank liquid collects the absorption heat of the concentrated liquid spread in the bleed tank (1), heats up the temperature, returns to the main absorption liquid pipe and passes through the high-temperature regenerator (1).
) to reach.

As described above, the present invention is to form an absorption liquid circulation path so that the absorption liquid is bypassed from the main absorption liquid circulation path of the absorption chiller/heater and sprayed into the bleed tank (2 drops); A sub-tank liquid pipe is formed to recover the gaseous refrigerant absorption 11i of the absorption liquid and return it to the regenerator, so that the internal pressure of the extraction tank rises and is maintained at a low level, so the cooling capacity of the absorption chiller/heater is reduced. If it is possible to do the same as above, the condensed gas can be removed from the machine.

Although the present invention has been described as a dual-effect absorption chiller/heater (62) in the embodiment shown in Figure 1 (2), it can be constructed similarly in the case of an active water chiller (62).
