本考案は冷凍装置の分流器に関し、詳しくは凝縮器から
の冷媒を分流して蒸発器に供給する分流器に関するもの
である。[Detailed Description of the Invention] The present invention relates to a flow divider for a refrigeration system, and more particularly to a flow divider that divides refrigerant from a condenser and supplies it to an evaporator.

数個の分流通路ｅ。Conventionally, as a flow divider for this type of refrigeration equipment, for example, as shown in FIG. , a plurality of branch passages e extending radially from the nozzle hole d of the nozzle C.
ｅ・・・に等しく分流して蒸発器に供給するようにした
ものがよく知られている。It is well known that the amount of water is divided equally into e... and supplied to the evaporator.
ところで、このような分流器Ａを用いた冷凍装置におい

を高めるよう能力制御して能力制御運転を行うようにし
た、いわゆるホットガスバイパス方式の能力制御を行う
ことがなされている。By the way, in a refrigeration system using such a flow divider A, conventionally, for example, as shown in FIG. The refrigerant is supplied to the refrigerant pipe i upstream of the flow divider A, where it is combined with the refrigerant from the condenser, and then divided by flow divider A and supplied to the evaporator j, thereby controlling the capacity to increase the evaporation temperature. A so-called hot gas bypass method of capacity control has been implemented in which capacity control operation is performed using a hot gas bypass method.

膨張弁および電磁弁である。Note that k and 1 are a hot gas control valve and a hot gas solenoid valve installed in the bypass pipe g, and m and n are temperature-sensitive valves installed in the refrigerant pipe i upstream of the flow divider A. They are expansion valves and solenoid valves.

されるため、該ノズルＣにより圧力が降下しホットガス
のバイパス量が制限され、能力制御範囲が狭という欠点
を有していた。However, in the conventional system, the hot gas from the compressor f is supplied to the evaporator j via the nozzle C of the flow divider A, so the pressure is lowered by the nozzle C and the bypass amount of the hot gas is limited. However, it had the disadvantage of a narrow capability control range.

一であるため、能力が変動したり、蒸発器からの吹出空
気温度にむらが生ずるという問題があった。Furthermore, at the connection point between the bypass pipe g and the refrigerant pipe i upstream of the flow divider A, the refrigerant flows unevenly due to the merging of the hot gas, resulting in insufficient and uneven mixing of the hot gas and the refrigerant. Therefore, there were problems in that the capacity fluctuated and the temperature of the air blown from the evaporator became uneven.

る。The present invention has been developed in view of this point, and in refrigeration control that performs capacity control using the hot gas bypass method as described above, a mixing chamber is provided downstream of the nozzle of the flow divider, and the condenser is bypassed in the mixing chamber. By supplying the hot gas from the compressor eccentrically to the axis of the mixing chamber and at an angle of approximately 90', the refrigerant and hot gas are mixed. In order to eliminate restrictions on the bypass amount of hot gas caused by such pressure drops, and to achieve good mixing of refrigeration from the condenser and hot gas, it is possible to sufficiently control the capacity of the hot gas. The purpose of this invention is to provide a flow divider for a refrigeration system.

A nozzle body having a nozzle communicating with the condenser is fitted into an upstream opening of a diverter body having a plurality of dividing passages communicating with the condenser, so that the upstream side communicates with the nozzle hole and the downstream side communicates with the nozzle hole. A mixing chamber is formed that communicates with each flow divider, and the gas supply port from the hole 1 for supplying the hot gas from the compressor to the mixing chamber is eccentric to the axis of the mixing chamber and at an angle of approximately 90°. The opening is at a certain angle, and the refrigerant from the nozzle hole and the hot gas from the hot gas supply port are mixed in the mixing chamber.

A hot gas supply port 8 for supplying hot gas from the compressor to the mixing chamber 7 is eccentric with respect to the axis O of the mixing chamber 7 and at an angle of approximately 90°. By opening at a certain angle and mixing the refrigerant from the nozzle hole 5 and the gas from the gas supply port 1 to the gas supply port 8 in the mixing chamber 7, the pressure drop is caused. Since the hot gas can be mixed well and uniformly with the refrigerant and supplied to the evaporator without restricting the bypass amount of the hot gas or causing uneven flow of the refrigerant, the evaporation temperature of the evaporator can be lowered. In order to increase the capacity, it is possible to accurately control the capacity within 4-1 minutes without fluctuation.

This has the advantage that the refrigerant and hot gas can be mixed more effectively and uniformly.
