Abstract:
본 발명은 조핵제 및 n-테트라데칸을 포함하는 상전이물질팩에 관한 것이다. 보다 구체적으로, 유기계 상전이물질 (PCM: Phase Change Material)인 파라핀계 탄화수소 n-테트라데칸(tetradecane)에 조핵제를 첨가하고 액상의 이들 물질이 외부로 새어나가는 것을 방지하도록 밀봉된 본체부를 포함하는 상전이물질팩에 관한 것이다. 이러한 조핵제가 첨가된 n-테트라데칸 상전이물질팩의 경우 조핵제가 첨가되지 않은 기존의 상전이물질팩에 비해 동결시간이 훨씬 단축되어, 전력소비 감소를 통한 제품의 가격경쟁력이 제고되는 장점이 있다. 또한 다량의 상전이물질팩들을 동결할 경우나 동일 상전이물질팩을 재사용하는 경우, 조핵제가 첨가되지 않은 기존의 상전이물질팩에 비해 동일 온도에서 동결하는 재현성이 월등히 향상되는 장점이 있다.
Abstract:
본 발명에 따른 에어 자켓은 부착부(60)를 적용하여 휴대형 냉각 기구(70)를 에어 자켓(10)의 자켓(20)에 일체형으로 결합시켜 사용할 수 있으므로, 종래 벨트, 허리띠를 사용하도록 하는 방식에 비해 착용이 편리하고, 작업시 냉각 기구(70)가 작업자의 움직임을 방해하지 않으므로, 편리한 사용을 제공한다. 또한, 에어 자켓을 위한 휴대형 냉각 기구는 용기내에 채워진 폴리머 겔과 같은 냉매(120)에 장입된 냉각 호스(110)를 통해 콤퓨레샤로부터 에어 자켓(10)으로 공급되는 공기의 온도가 낮추어지므로, 냉기를 형성하기 위해 콤퓨레샤로부터 공급되는 공기량의 손실이 발생되는 볼텍스 튜브와 대비할 때 콤퓨레샤로부터 공급되는 공기량을 그대로 사용하여 냉방 효율을 증가시키고, 공기량의 과다사용을 방지하여 에너지 효율을 높일 수 있다.
Abstract:
An impingement plate atomizer apparatus includes an electrostatically charged longitudinal member having an upper surface sized and shaped to receive a liquid cryogen thereon, a lower surface opposite to the upper surface, and at least one hole extending through the longitudinal member; an ultrasonic transducer in contact with the longitudinal member for providing ultrasonic energy thereto for atomizing the liquid cryogen into an electrostatically charged cryogen fog. A method is also provided for providing an eiectrostaticaily charged cryogen fog.
Abstract:
The present invention relates to a pump (15) for pumping a coolant (9) within a Dewar vessel (1) and to a corresponding Dewar vessel (1) for storing samples in a coolant (9). The Dewar vessel (1) comprises a thermally insulated reservoir (3) for the coolant (9) and a sample vessel (11) provided separately and arranged in the thermally insulated reservoir (3). The reservoir (3) is connected to the sample vessel (11) in such a way that the level of coolant (9) is constant in the sample vessel (11). Pump (15) may help in keeping the level of coolant (9) in the sample vessel (11) constant. For this purpose the pump (15) comprises a chamber (17) with an inlet (19) and an outlet (21), a closing element (23) and a pressure increasing device (25). Therein, the inlet (19) is connectable to the reservoir (3) and the outlet (21) is connectable to a sample vessel (11) of the Dewar vessel (1). The chamber (17) is adapted to fill with coolant (9) through the inlet (19) by gravity and the closing element (23) is adapted to automatically close the chamber (17) when it is full of coolant (9). The pressure increasing device (25) is adapted to increase the pressure within the chamber (17), after the chamber (17) is closed, until the coolant (9) is released through the outlet (21).
Abstract:
A cooling system (1), especially for cryopreserving biological samples (2), comprises a cooling chamber (100) and a cooling device (200) for cooling the cooling chamber (100) using liquid nitrogen (220). At least one of the side walls (120) includes at least one predetermined wall element (125) which is essentially designed like the surrounding load-bearing wall and can be moved relative to said load-bearing wall in such a way that a wall opening can be formed in the side wall (120). The cooling system can also comprise a protective device, in particular a dome, to create a local protective atmosphere for an operator (3). A lifting device, e.g. to provide protection against floods, and/or an envelope device to create a protective atmosphere for the entire cooling system, can be additionally provided. Methods for operating the cooling system (1) in case of an emergency are also described.
