混合使用される希釈用冷水として使用している。In such a chilled water discharging apparatus, a cooling water coil stored in a cooling water tank is provided with a refrigerant coil of a refrigeration circuit and a cooling coil of a chilled water discharging pipe through which cooling water flows. Then, an ice layer is formed around the refrigerant coil by the operation of the compressor of the refrigeration circuit, the cooling water is cooled by the ice layer, and the cooling water is used as a medium to flow through the cooling water and the cooling coil. By obtaining cold water by heat exchange with water for cooling, it is used as cold water for drinking directly or as cold water for dilution used by mixing with beverage ingredients.

た状態で支障なく注出される。[0004] The cooling water in the cooling water tank is an ice layer formed on the refrigerant coil, and is controlled so as to keep the temperature around 0 ° C, which is not always supercooled and frozen. That is, during normal operation, by controlling the power cutoff of the compressor in accordance with the detection output of the icing sensor arranged on the outer periphery of the refrigerant coil, the ice layer formed on the refrigerant coil is maintained at a predetermined thickness. Thereby, the temperature of the cooling water in the cooling water tank is maintained at about 0 ° C. which is out of the supercooling temperature range, so that the cold water discharged through the cold water discharging pipe is set to an appropriate temperature for drinking, for example, 6 ° C. It is poured without trouble in the state of being cooled back and forth.
【０００５】また、冷却水槽の冷却水中にはアジテータ

冷却水を撹拌している。Further, an agitator is arranged in the cooling water in the cooling water tank, and the agitator is constantly operated during the operation to stir the cooling water.

ることになる。On the other hand, the initial stage of the operation in which the operation is restarted after the temperature of the cooling water in the cooling water tank has just returned to normal temperature immediately after the start of operation or after the operation has been stopped, that is, the power cutoff of the compressor is controlled by the ice layer thickness. In the process of forming icing before shifting to the normal operation state, it is first assumed that a stable ice layer is formed. In other words, the so-called rising time (normal operation by ice layer thickness control) until the appropriate temperature chilled water as the chilled water for drinking can be obtained at an early stage and the stable supply of the appropriate temperature chilled water for continuous pouring (when there are many users, etc.) Transition to).

がより立ち上がり時間が早まることになる。To this end, priority is given to the icing control operation of the compressor by detecting the temperature of the cooling water in the cooling water tank. In this connection, even when the temperature of the cooling water in the cooling water tank is in the supercooling temperature range, it is more preferable to stop the compressor after a certain period of time without immediately stopping the operation of the compressor. The rise time will be faster.

い。[0009] The icing start operation is started when the environment is ready. However, the operation is not always reproducibly coincident with the operation of the compressor or immediately after the compressor is stopped. The sherbet-shaped cooling water instantaneously freezes and floats on a part of the cooling water in the water tank in a state where the cooling water is sherbet-shaped, and icing is formed on the outer peripheral portion of the refrigerant coil. When the icing is performed, the water temperature in the cooling water tank, which was in the supercooling temperature range, rapidly rises to about 0 ° C. Therefore, even if the supercooling operation is continued, the cooling water in the cooling water tank is affected by this effect. No phenomena such as freezing of the whole or freezing of the cooling water staying in the cold water discharge pipe immediately occur.

ｍ３相当が目安となっている。However, if a small amount of chilled water is discharged from the chilled water discharge line just before the refrigerant coil in the subcooling operation starts icing, the refrigerant stays in the chilled water discharge line. A phenomenon in which the flowing cold water instantaneously turns into a sherbet state may occur, which may hinder the pouring operation. In addition, the small-volume pouring here refers to a pouring amount of about 10 cm3 which is used when a cold drink is added to a suitable temperature hot water at the time of pouring a hot beverage to make a ready-to-drink beverage. Approximately 100c per cup for metering
m3 equivalent has become a guideline.

運転の影響を受けているので、注出タイミングや注出量
などによる条件次第では発生する現象であることが、種
々の実験の結果から判明するに至った。This phenomenon is caused by the fact that during normal operation after the formation of an ice layer having a predetermined thickness on the outer periphery of the refrigerant coil, the formation of the ice layer is stabilized and the cooling water in the cooling water tank is maintained at about 0 ° C. Although this phenomenon did not occur, during the above-mentioned supercooling operation, the cold water staying in the chilled water injection pipe was also affected by the supercooling operation, so it depends on conditions such as the injection timing and the amount of injection. It has been found from the results of various experiments that this phenomenon occurs.

ーベット状化することによるものと推測される。In addition, when about 100 cm3 or more is poured out per cup, a phenomenon that hardly occurs even during the supercooling operation has been obtained from the results of the experiment. When the cold water flows, the amount of heat taken away from the water supply is small, unlike the case where the cold water is flowed, so that the pressure fluctuation generated in the cold water discharge pipe easily triggers icing in terms of timing, and the cold water injection It is presumed that the cold water that had stayed in the outlet pipe was instantaneously turned into a sherbet.
