Abstract: PURPOSE: A flaring expander is provided to improve efficiency and effectiveness of a flaring task by measuring the length of the flared copper pipe easily through grooves and markings. CONSTITUTION: A flaring expander includes a flare bar(210) and an expansion cove(250). A plurality of holes are formed on the flare bar. The expansion cone is inserted into the hole, and performs flaring operation by compressing the predetermined surface of a fixed copper pipe(20). The markings are carved on the predetermined side of the expansion cone. The flaring expander further includes a fixed handle(212), a convey bar(240), and a knob(230).

Abstract: An insect screen apparatus opened and closed with a window is provided to stop the window at a fixed position in opening and closing the window and the insect screen and prevent damage to the insect screen due to restitution force acting on the insect screen. An insect screen apparatus(10) opened and closed with a window comprises: a rotary axis equipped with an elastic unit; an insect screen(150) in which one end is fixed to the rotary axis and a separable part is equipped in the other end; a window frame unit(100) in which several windows(120) are inserted inside; an insect screen fixing unit which prevents the insect screen from being wound with the restitution force of the elastic unit; and a joint(140) which is formed in the end part of the window and in which a separable unit of the insect screen is adhered.

Abstract: A cooling/heating device having a branched pipe for collecting refrigerant early is provided to improve heating and cooling performances by exchanging heat of a vapor refrigerant and a liquid refrigerant in an auxiliary heat exchanger. A cooling/heating device having a branched pipe for collecting refrigerant early comprises a compressor(250), an outdoor device(200), a first branched pipe(220), an expansion valve(260), an indoor device(210), a second branched pipe(230), a first four-way valve(270), an auxiliary heat exchanger(240), and a second four-way valve(280). The first branched pipe is branched from the outdoor device, and collects the liquid refrigerant condensed in the outdoor device and sends the liquid refrigerant to the auxiliary heat exchanger. The second branched pipe is branched from the indoor device, and collects a vapor refrigerant early evaporated in the indoor device and sends the vapor refrigerant to the auxiliary heat exchanger. The auxiliary heat exchanger exchanges heat of the liquid refrigerant and the vapor refrigerant.
Abstract translation: 提供一种具有用于早期收集制冷剂的分支管的冷却/加热装置，以通过在辅助热交换器中交换蒸气制冷剂和液体制冷剂的热量来改善加热和冷却性能。 具有用于早期收集制冷剂的分支管的冷却/加热装置包括压缩机（250），室外装置（200），第一分支管（220），膨胀阀（260），室内装置（210）， 第二分支管（230），第一四通阀（270），辅助热交换器（240）和第二四通阀（280）。 第一分支管从室外装置分支，并收集在室外装置中冷凝的液体制冷剂，并将液体制冷剂送到辅助热交换器。 第二分支管从室内装置分支，并收集在室内装置中早期蒸发的蒸汽制冷剂，并将蒸气制冷剂送到辅助热交换器。 辅助热交换器交换液体制冷剂和蒸气制冷剂的热量。
