摘要： PROBLEM TO BE SOLVED: To improve the manifesting efficiency of the oxidizing force of a photocatalyst and the regenerating efficiency of an adsorbent in a deodorizing element carrying the photocatalyst and adsorbent. SOLUTION: A deodorizing element contains an adsorbent 10 composed mainly of silica and alumina and a photocatalyst 11, both of which are separately contained in a structure 9 composed of inorganic fibers after the adsorbent 10 and photocatalyst 11 are dried by heating. The adsorbent 10 composed mainly of silica and alumina hardly absorb light, such as ultrasonic rays, etc., due to its white appearance even when the adsorbent 10 is irradiated with the light under the presence of an odor material and can efficiently project light upon the photocatalyst 11. Therefore, the manifesting efficiency of the oxidizing force of the photocatalyst 11 can be improved and the deodorizing speed of the odor material and the regenerating speed of the adsorbent 10 can be improved. In addition, the life of the deodorizing performance of the deodorizing element can be prolonged.

摘要： PROBLEM TO BE SOLVED: To avoid condensation within a refrigerant piping and corrosion of the refrigerant piping by always maintaining an interior of the refrigerant piping that is left unattended for a long time after an installation work at a site at a low humidity. SOLUTION: This refrigerant piping controller comprises a refrigerant piping 1, a ventilation means 2 for ventilating an interior of the refrigerant piping 1 so as to lower humidity and an inflow resistance means provided with a ventilation hole 6 having an inner diameter smaller than that of the refrigerant piping 1 for restricting inflow rate of fresh air, and the ventilation means 2 is connected to a pipe end at an upper side of the piping 1, and the inflow resistance means 5 is connected to a piping end at a lower side of the pipe. By this constitution, even if the refrigerant piping 1 is left unattended for a long time at an installation site, the interior of the piping 1 can be always ventilated by operating the ventilation means 2 so as to keep the interior of the piping at a low humidity while the piping is left unattended and condensation and corrosion are prevented from occurring.

摘要： PROBLEM TO BE SOLVED: To prevent iron powder from invading a compressor and further prevent wear of compressor slide parts from being promoted by capturing iron powder, cut chips, and oxidized scale, etc., in a refrigerant introduction pipe in a gas/liquid separator where an oil return hole is provided in the refrigerant derivation pipe. SOLUTION: The present gas/liquid separator is adapted such that the tip end of a refrigerant introduction pipe 5 is sealed, and a hole 6 is provided in a portion of the refrigerant introduction pipe 5 in the gas/liquid separator 1, and further a filter 9 comprising a wire material is disposed in the neighbourhood of the tip end of the refrigerant introduction pipe 5. Hereby, iron powder, etc., are captured at the end of the refrigerant introduction pipe 5 to prevent the iron powder, etc., from being mixed into the gas/liquid separator 1 and further iron powder, etc., invading a compressor from an oil return hole 8 provided in the refrigerant derivation pipe 7 are restricted. Thus, wear of compressor slide parts are prevented from being promoted.
