Title:
METHOD FOR CONSTRUCTION OF AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3637716
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To execute a simple method for construction of an air conditioner in consideration of an effect on an environment by a method wherein the air in an indoor machine and a connection piping is purged selectively from inside the air conditioner by utilizing a gas permeation function of a membrane.
SOLUTION: An indoor machine 6 and an outdoor machine 2 are connected by an indoor-outdoor connection piping 10, and a jig 9 equipped with a gas permeation membrane (polyimide) is fitted to a gas-side three-way valve 7 of the outdoor machine 2. By opening a screw part 9 of the gas-side three-way valve 7 and by opening a screw part 5 of a liquid-side two-way valve 4 subsequently, a refrigerant in the main body of the outdoor machine 2 is introduced into the connection piping and the indoor machine 6, while the pressure in a system rises. Since the gas permeation membrane has a characteristic of making air permeate selectively more than the refrigerant, the air in the indoor machine 6 and the connection piping is released into the atmosphere selectively through the gas permeation membrane, being facilitated by a partial pressure difference between the internal pressure having risen and the outside and by gas permeation selectivity.
