REFRIGERANT DISTRIBUTOR, REFRIGERATION CYCLE AND AIR CONDITIONER USING IT

摘要

PROBLEM TO BE SOLVED: To distribute a refrigerant uniformly regardless of the installation conditions of a refrigerant distributor when a bend is present in the piping for a gas-liquid two-phase refrigerant at the inlet of an inlet pipe by stirring and mixing the refrigerant not to cause separation of gas-liquid regardless of shifted flow and to suppress noises being generated when the gas-liquid two-phase refrigerant passes through the distributor. SOLUTION: In a refrigerant distributor for distributing a gas-liquid two-phase refrigerant from an inlet pipe to a plurality of outlet pipes through a mixing section, a branch space and a branch section, a relation L1/D1>2 is satisfied between the inside diameter D1(m) and the length L1(m) of the mixing section and a relationΔP/W<7 is satisfied between the loss of refrigerant pressureΔP(Mpa) at the outlet of the branch space and the mass flow W(kg/s) of the refrigerant flowing through the mixing section.
