A heat exchanger unit includes a heat exchanger main body in which a first heat exchanger and a second heat exchanger are arranged in series relative to a refrigerant flowing direction and an air flowing direction. The heat exchanger main body includes on one side thereof an external connection portion configured to supply at least refrigerant and on the other side thereof a communicating portion configured to connect (allowing fluid communication between) the first heat exchanger and the second heat exchanger. A bypass flow path extends from the one side to the other side of the heat exchanger main body, and is configured to bypass the first heat exchanger. At least one of the first heat exchanger and the second heat exchanger includes a pair of tank sections disposed at an interval, and a plurality of first heat transfer tubes configured to connect the pair of tank sections.

Provided is a cellulose resin composition wherein roll contamination during processing and reduction in the productivity caused by roll contamination are inhibited. The cellulose resin composition is obtained by adding a polyester-based plasticizer to a cellulose resin, the cellulose resin composition being characterized in that the polyester-based plasticizer is produced from a polybasic acid, a polyhydric acid and, as required, a stopper, in which polyester-based plasticizer, components having a molecular weight of 430 or less are removed to an amount of 5 wt % or less.

Cellulose resin composition

Provided are a cellulose resin composition which can give a cellulose ester film free from the problems with bleeding and has excellent moisture permeability, even when containing a plasticizer in a relatively large amount, and a cellulose resin film which is obtained from the cellulose resin composition. The present invention relates to a cellulose resin composition obtained by adding (A) a polyester plasticizer to a cellulose resin. The aforementioned (A) polyester plasticizer is obtained from a polybasic acid, a glycol and a stopper, wherein 70 to 30 mol % of the aforementioned polybasic acid is a succinic acid and/or an adipic acid; 30 to 70 mol % of the aforementioned polybasic acid is at least one selected from a group consisting of a terephthalic acid, a phthalic acid and an isophthalic acid; the aforementioned glycol is at least one selected from a group consisting of an ethylene glycol, a 1,2-propylene glycol, a 1,3-butanediol and a 2-methyl-1,3-propanediol; the aforementioned stopper is an acetic acid and/or a benzoic acid; and the weight-average molecular weight is 600 to 2,000.

Cellulose resin composition and cellulose resin film

Provided are a cellulose resin composition and cellulose resin film which are free from the problem of bleeding even when containing a plasticizer in a relatively large amount. The present invention relates to a cellulose resin composition obtained by adding (A) polyester plasticizer to a cellulose resin, wherein the aforementioned (A) polyester plasticizer is obtained by allowing a polybasic acid and a polyalcohol to react and 80 mol % or more of said polybasic acid is a succinic acid and an adipic acid. The present invention also relates to a cellulose resin film obtained from the cellulose-based resin composition.

An evaporator includes two heat exchangers including an entry-side heat exchanger and an exit-side heat exchanger which are arranged opposite each other. The entry-side heat exchanger has a first path, a second path, and a third path, and the exit-side heat exchanger has a fourth path, a fifth path, and a sixth path. The sectional area of heat exchange passages of the first path in which refrigerant from an entry firstly flows downward is set smaller than the sectional area of heat exchange passages of the fifth path in which the refrigerant lastly flows downward. The sectional area of heat exchange passages of the sixth path in which the refrigerant to an exit lastly flows upward is set smaller than the sectional area of heat exchange passages of the second path in which the refrigerant firstly flows upward.
