61 | Air conditioner for preventing corrosion of evaporator | US09030586 | 1998-02-25 | US06182741B2 | 2001-02-06 | Keiichi Yoshii; Sadayuki Kamiya |
An air conditioner includes a case accommodating an evaporator having a core portion and a lower tan disposed at a bottom of the core portion. The case has a recess portion disposed at an upstream air side of the evaporator, and a covering wall is formed to extend upwardly from the bottom of the recess portion to cover only the lower tank at an immediately upstream air side. When air passes through the evaporator, alien substances contained in air collide with the evaporator and fall to be deposited in the recess portion. Therefore, the deposition of the alien substances do not directly adhere to the lower tank of the evaporator to prevent the evaporator from being corroded. | ||||||

A method of inhibiting corrosion and the formation of hydrogen and thus improving absorption in an ammonia/water absorption refrigeration, air conditioning or heat pump system by maintaining the hydroxyl ion concentration of the aqueous ammonia working fluid within a selected range under anaerobic conditions at temperatures up to 425.degree. F. This hydroxyl ion concentration is maintained by introducing to the aqueous ammonia working fluid an inhibitor in an amount effective to produce a hydroxyl ion concentration corresponding to a normality of the inhibitor relative to the water content ranging from about 0.015 N to about 0.2 N at 25.degree. C. Also, working fluids for inhibiting the corrosion of carbon steel and resulting hydrogen formation and improving absorption in an ammonia/water absorption system under anaerobic conditions at up to 425.degree.

63 | Method for removal of acid from compressor oil | US519095 | 1995-08-24 | US5770048A | 1998-06-23 | Robert Peter Scaringe; Nidal Abdul Samad; Lawrence Robert Grzyll |
An alcohol, specifically ethanol, methanol and isopropanol, is used to remove acid from a refrigeration system, a heat pump or an air conditioner. The alcohol vaporizes acid, primarily inorganic acid, in the system and, in the filter/dryer, reacts with surfaces or is adsorbed. The alcohol, the quantity of which is determined from the capacity of the filter/dryer, is introduced into the compressor oil sump for thorough mixing with the oil during compressor lubrication. | ||||||

A heat exchanging apparatus includes a composite structure of a ferrosoferric oxide and a molybdenum oxide at the internal surface of a heat exchange cycle tube located in a generator. A process of suppressing corrosion of this heat exchanging apparatus includes the step of preparing an ammonia solution including dissolved oxygen of a concentration of approximately 3-8 ppm. Approximately 1 wt %-5 wt % molybdate is added into the ammonia solution. This ammonia solution is sealed within the heat exchange cycle tube to be heated to at least a predetermined temperature in the generator of the heat exchanging apparatus. Thus, a composite structure of a ferrosoferric oxide and molybdenum oxide is formed on the internal surface of the generator. This composite structure allows the suppression of corrosion in the internal surface of the generator. | ||||||

The upstream side ends of fins (16) along the ventilating direction project out relative to the upstream side ends along the ventilating direction of tubes (14) without being allowed to project out beyond the end faces of tanks (2) and (3) along the ventilating direction so as to set the tubes (14) at positions recessed toward the downstream side along the ventilating direction relative to the fins (16), and the downstream side ends of the fins (16) along the ventilating direction are recessed further toward the upstream side along the ventilating direction relative to the downstream side ends of tubes (15) along the ventilating direction. As a result, the evaporator achieves a lower profile along the ventilating direction and, at the same time, condensed water manifesting at the surfaces of the tubes and fins is drained downward with a high degree of efficiency, thereby minimizing occurrence of spattering of the condensed water onto the downstream side and also, it becomes possible to prevent corrosion from advancing at the tubes due to dirt adhering onto the upstream side of the tubes along the ventilating direction. |

Pipes (40) of a predetermined length are filled with a nitrogen gas (4a). Cross-sectionally hat-shaped plugs (50) comprising a brazing filler metal are press fitted in open ends of joint portions (42, 42) at both ends of the pipes (40) so as to seal the pipes (40), whereby the plugs (50) are fixed to the joint portions (42, 42). One side portion of a connecting piece (60) is then inserted into the joint portion (42) of one pipe (40) by breaking the relative plug (50) thereby, while the other side portion of the connecting piece (60) is inserted into the joint portion (42) of the other pipe (40) by breaking the relative plug (50) thereby. The plugs (50) are then melted to braze the joint portions (42) of the pipes (40) and the connecting piece (60) to each other. | ||||||
