ての性能低下をきたすという問題が生ずる。 In general, a turbo refrigerator is constructed with a flooded evaporator 1', a turbo compressor 2', and a condenser 3' as its main components, as shown in FIG. In the pipe body 4' of the flooded evaporator 1', there is a refrigerant liquid level.
An eliminator 5' is disposed above L', and the eliminator 5' performs gas-liquid separation of the evaporative refrigerant (see Japanese Utility Model Publication No. 30213/1983). However, since the thickness of the eliminator 5' is constant over the entire length, the flow velocity passing through the suction pipe 6' provided at the top of the tube body 4' near the inlet 6a' is far from the suction pipe inlet 6a'. faster than the parts. Therefore, the refrigerant gas-liquid separation in the eliminator 5' at the suction pipe inlet 6a' becomes poor, and some liquid refrigerant is sucked into the turbo compressor 2', causing a decrease in efficiency. On the other hand, in order to prevent this, if the entire eliminator 5' is made thicker, it is possible to prevent liquid refrigerant from being sucked into the turbo compressor 2', but this increases ventilation resistance and causes the problem of deterioration of performance as an evaporator. .

とする。 In view of the above-mentioned problems, the purpose of the present invention is to achieve almost complete separation of refrigerant into gas and liquid without degrading the performance of the evaporator. A liquid type evaporator is characterized by a structure in which an eliminator is provided above the refrigerant liquid level in the tube body so that the ventilation resistance in the portion near the suction piping entrance can be made greater than the ventilation resistance in the portion far from the suction piping entrance. shall be.

口、１０は被冷却水出口である。 The flooded evaporator 1 has a turbo compressor 2 at the top.
A plurality of cooling pipes 8,
8... are disposed horizontally to exchange heat between the liquid refrigerant housed in the pipe body 4 and the liquid to be cooled, such as water, flowing through the cooling pipes 8, 8..., and the liquid refrigerant is It is configured to evaporate. Reference numeral 9 represents an inlet of water to be cooled, and 10 represents an outlet of water to be cooled.
前記管胴４内には、冷媒液面Ｌの上位に、蒸発

引されるのを防止できる。 The eliminator 5 is configured such that the thickness t 1 of the suction pipe 6 near the inlet 6 a is larger than the thickness t 2 of the part far from the suction pipe inlet 6 a. Therefore, the ventilation resistance of the eliminator 5 is greater at a portion closer to the suction pipe inlet 6a than at a portion farther from the suction pipe inlet 6a. By doing this, the flow velocity distribution of the evaporated gas refrigerant passing through the eliminator 5 and being sucked into the suction pipe 6 becomes almost uniform regardless of the distance from the suction pipe inlet 6a, and the turbo compressor 2 By appropriately selecting the suction force, it is possible to prevent the liquid refrigerant from being sucked together with the gas refrigerant.

In this case, the eliminator 5 is provided only in a portion close to the suction pipe inlet 6a to eliminate ventilation resistance in a portion far from the suction pipe inlet 6a. By doing so, the flow velocity distribution of the evaporated gas refrigerant can be made almost uniform regardless of its distance from the suction pipe inlet 6a.

果がある。 According to the present invention, in the pipe body 4, the ventilation resistance of the portion close to the inlet 6a of the suction pipe 6 provided at the top above the refrigerant liquid level L is made greater than the ventilation resistance of the portion far from the suction pipe inlet 6a. Since the eliminator 5 is provided to make the flow velocity distribution of the evaporated gas refrigerant uniform, by appropriately selecting the suction flow velocity to the suction pipe 6, it is possible to almost completely separate the liquid from the gas refrigerant. This has the practical effect of increasing efficiency.
