PURPOSE: A tube system for circulating hydrogen of cooling and heating air conditioner and refrigerating and freezing system using metal alloy for hydrogen storage is provided to maximize cooling, heating, refrigerating and freezing efficiency and to extend life of a compressor and a pump. CONSTITUTION: Transporting pipes(A,A') with hydrogen filters(11,11') are connected to heat exchangers(1,1'). An intake pipe(B) and a hydrogen direct delivery pipe(C) are installed between the transporting pipes so that both ends of the intake pipe and the hydrogen direct delivery pipe meet on the transporting pipes to be connected with each other. A discharge pipe(E) with a hydrogen filter(7) and connected with a compressor(5) is connected with the intake pipe and the hydrogen direct delivery pipe. Three-way valves(6a,6a') are installed on points where the intake pipe, the hydrogen direct delivery pipe and the transporting pipes meet. Hydrogen is transported between the heat exchangers by the compressor to generate chilled air and hot air. The chilled air and the hot air is used selectively by a damper(2).
