摘要： An air-cooled heat exchanger is provided. A reinforcement beam is laterally attached to an upper surface of a guide housing which is formed to have a dome shape having an area gradually increasing in a downward direction from the stack to guide air discharged to the stack. In another aspect, an air-cooled heat exchanger may further include an enclosure surrounding a power transmission part configured to transmit a rotation force of a motor to the fan to rotate the fan. In still another aspect, a power transmission part may include a drive pulley coupled to a rotation shaft of a motor part, a driven pulley coupled to a drive shaft of a fan, and a belt installed between the drive pulley and the driven pulley to transmit a rotation force of a motor, and an enclosure may include a drive pulley enclosure part of which an outer surface is fixed to the motor part and which surrounds the drive pulley, a driven pulley enclosure part which includes a lid coupled to a lower surface of the driven pulley enclosure part and openable and closeable downward and surrounds the driven pulley, and a belt enclosure part surrounding the belt.

摘要： A heat exchanger arrangement (2) comprises at least one heat exchanger (4) including at least one substantially horizontally oriented manifold (6a, 6b) forming an upper side of the at least one heat exchanger (4), the at least one manifold (6a, 6b) having lateral end portions (8); and a support structure (10) including a main portion comprising, at least partially, a metallic material, and manifold support portions (14) associated to respective lateral end portions (8) of the at least one manifold (6a, 6b). The manifold support portions (14) are made at least partially from a non-metallic material and configured to receive the lateral end portions (8) of the at least one manifold (6a, 6b) for preventing the at least one manifold (6a, 6b) from contacting any metallic portions of the support structure (10).

摘要： An air conditioner and control method for reducing power consumption by controlling pressure or temperature of a refrigerant. The air conditioner includes a compressor compressing a refrigerant and discharging a high pressure refrigerant gas; an outdoor heat exchanger in which the high pressure refrigerant gas is changed to a refrigerant fluid; an outdoor fan to blow outdoor air to the outdoor heat exchanger; a decompressor decompressing the refrigerant fluid into a low pressure state; an indoor heat exchanger changing the decompressed low pressure refrigerant fluid to a refrigerant gas; and a controller configured to control pressure or temperature of the refrigerant based on an operation condition including at least two of a first condition determined based on an installation environment, a second condition determined based on an optimal compression ratio of the compressor, a third condition determined based on outdoor temperature, and a fourth condition set as a default value.
