MULTIFUNCTIONAL REFRIGERANT CONTROL VALVE DEVICE, AND MULTIFUNCTIONAL REFRIGERANT CONTROL VALVE SYSTEM

摘要

PROBLEM TO BE SOLVED: To achieve size reduction and energy saving of a heat pump air conditioner.;SOLUTION: A multifunctional refrigerant control valve device 6 is used in a heat pump air conditioner 1 for carrying out a cooling operation and a heating operation using a refrigerant cycle, and switching the cooling operation and the heating operation by changing circulation paths for refrigerant in a four-way valve 5. The multifunctional refrigerant control valve device includes: a body 30 to which refrigerant is supplied; a cylindrical main shaft 50 provided in the body 30; an expansion valve mechanism 60 disposed in the main shaft 50 movably in an axial direction of the main shaft 50, and for reducing the pressure of the refrigerant supplied to the inside of the body 30, and adjusting a flow amount of the refrigerant; and a three-way valve mechanism 80 disposed on the outer periphery of the main shaft 50 movably in the axial direction of the main shaft 50, and for switching supply destinations of the refrigerant in the four-way valve 5.;COPYRIGHT: (C)2013,JPO&INPIT
