Title:
空気調和機からの冷媒回収方法
Document Type and Number:
Japanese Patent JP4107065
Kind Code:
B2
Abstract:
PURPOSE: A method for recovering a refrigerant from an air conditioner is provided to efficiently recover a refrigerant without using power, thereby reducing a burden of a worker. CONSTITUTION: An air conditioner has a two-way valve(6) and a three-way valve(7) in an outdoor unit(4) as a connecting port. Both the two-way valve and the three-way valve are in a closed state. A refrigerant recovering pump(9) is connected to a service port of the three-way valve. The refrigerant recovering pump is connected with a refrigerant recovering container(15). The refrigerant recovering pump generates a suction-exhaust action effect by operating a check valve for suction(95) and a check valve for exhaust(96) by driving a piston(92) inside a cylinder container(91), thereby recovering the refrigerant remaining inside an indoor unit and connecting pipes(2,3) into the refrigerant recovering container.
