| A method for retrofitting an aircraft air conditioning unit drainage system comprises the step of removing drain pipe from the unit housing. A hole from which the drain pipe extends is plugged. A first location within a unit housing is determined where during operation of the unit air pressure is lower than at a second location. A second location below the first location is also determined where pooling occurs. A first and a second conduit with first and second internal diameters are respectively located at the first and the second locations. The first conduit and the second conduit are connected to a third conduit which extends generally vertically and which has a third internal diameter that is generally equal to the first internal diameter. A fourth conduit with a fourth internal diameter that is less than the second internal diameter is connected to the third conduit below the second location. | ||||||

| 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). | ||||||

The conduit includes an inlet portion that is connected to the chamber at a second location where condensate accumulates. A gravitational separator portion which extends below the second location is connected to the outlet portion and the inlet portion. A draining portion having an orifice for allowing condensate to exit the conduit is connected to the gravitational separator portion below the second location. The first location is chosen such that during operation of the unit the pressure at the first location is less than the pressure at the second location. | ||||||

| In a compressed air powered refrigeration system for aircraft containing a refrigeration turbine and associated heat exchangers for supplying cool air to the aircraft cabin, air is recirculated from the cabin by a recirculation means and combined with the turbine discharge air to simultaneously melt ice present in the turbine discharge and provide cooling to the recirculated air. The lack of ice in the turbine discharge allows the use of an ice-free regenerative heat exchanger, in heat exchange relation with the mixture of the turbine discharge air and recirculated cabin air, to condense moisture from the air entering the turbine. The use of heat from the cabin air to melt ice coupled with maximum utilization of the recirculation means supplying the recirculating cabin air enables the turbine to provide air at a temperature below freezing and results in improved cycle efficiency as well as maximum possible ventilation rate to the load. | ||||||

| The invention relates to a ducted refrigeration unit for continuously supplying quantities of refrigerated air to a group of refrigerated food display cases. The unit has two chambers arranged in parallel with a cooling coil disposed in each chamber. A liquid refrigerant is selectively and alternately supplied to one coil during the time a hot defrosting gas is supplied to the other coil. Damper means alternately direct circulating air through the chamber in which the coil thereof is supplied with a liquid refrigerant while bypassing the chamber in which the coil thereof is being defrosted.

| PROBLEM TO BE SOLVED: To provide a hot-keeping/cold-keeping coaster for beverage of which the power consumption is greatly reduced. SOLUTION: This hot-keeping/cold-keeping coaster for beverage is equipped with a coaster main body 10, and an electronic heat pump module 1 which cools one surface side of the coaster main body 10, and in the meantime, heats the other surface side of the coaster main body 10. The electronic heat pump module 1 is equipped with a vacuum diode type electronic heat pump device, and therefore, the power consumption can greatly be reduced more than by a cooling mechanism of a Peltier element.

| 55 | Refrigerator equipped with defrosting chamber | JP5684885 | 1985-03-20 | JPS61213514A | 1986-09-22 | ARIMA KATSUHIKO |
| PURPOSE:To defrost quickly and uniformly in spite of the height of defrosted substance by a method wherein only first high-frequency generator is operated in case the height of the defrosted substance is lower than a reference value while first and second high-frequency generators are operated sequentially in case the height of the same is higher than the reference value. CONSTITUTION:A height detecting unit 1, detecting the height of the defrosted substance, is arranged in a part of the defrosting chamber formed by parti tioning a part of a cold storage chamber while the first and second high-fre quency generators 9, 11, oscillating in different high-frequencies, are provided in the refrigerator. The frequency of the first high-frequency generator 9 is set at higher frequency than the same of the second high-frequency generator 11 while a defrost control means, consisting of a comparison circuit 3, a timer circuit 8 and the like, operates only the generator 9 in case the height of the defrosted substance is lower than the reference value, however, the same means operates the generator 9 and the generator 11 sequentially in case the height of the same is higher than the refrence value. As a result, the substance to be defrosted may be defrosted quickly and uniformly in spite of the height of the same. | ||||||
| 56 | Finned tube type heat exchanger | JP17541984 | 1984-08-23 | JPS6152591A | 1986-03-15 | YOSHIOKA SHINPEI; KUBOTA TORU |
| PURPOSE:To elongate the heating operation time as well as to enable to educe the defrosting time, by a method wherein one side surface within two confronting surfaces of each fin is made hydrophilic natured, and the other surface is made repellant. CONSTITUTION:Many of plate type fins are attached to a tube 11 in which medium is flowed nearly parallel with the space, and within two confronting surfaces of each fin 12, one surface is made hydrophilic natured and another surface is made repellent. Though frost is generated on the hydrophilic natured surface by the frosting while the heating operation, the frosting is delayed on the repellant surface, so to speak, the heating operation time can be elongated until the time when it becomes necessary to remove frost, the space of the fin 12 being closed by the frosting on both surfaces. In time of de-frosting, since water by thawing of frost flows down along the side of the hydrophilic natured surface, and on the repellant surfaces water is removed rapidly from the fins 12, the de-frosting time is reduced. | ||||||

| PURPOSE:To improve the heat transfer performance and the defrosting efficiency of the heat exchanger by disposing air inlet side fin group and a concave and convex fin group on the air outlet side overlapping in an air stream direction. CONSTITUTION:Flat shaped fins 12 and wave-shaped fins 13 are alternately disposed on the air outlet side, and flat shaped fins 11 are disposed on the air inlet side and wave-shaped fins 13 are disposed at positions where are overlapped in the air stream direction. Particularly, the air stream repeates refraction, expansion and contraction, and the air heat coefficient in the wave-shaped fins 13 increases. As a result, the heat exchange quantity increases and a frost layer is formed in the wave-shaped fins 13. Hence, at the time of defrosting heat is not discharged excessively but the defrosting efficiency is also improved. Further, in the undulation shape fins, such as wave-shaped fins, the heat transfer property is not rapidly lowered by the formation of the frost layer. | ||||||
