Title:
HEAT PUMP SYSTEM
Document Type and Number:
Japanese Patent JP2001241782
Kind Code:
A
Abstract:
To provide a heat pump system capable of improving system reliability by using a same storage unit even at a low boiling point storage time and a high boiling point storage time with a simple constitution, reducing in size a fractionating circuit and preventing stagnation of an excess refrigerant or a refrigerating machine oil.
A storage unit 39 is disposed at a lower position than a bottom of a fractionating tower 38. The bottom of the tower 38 is connected to an upper part of the unit 39 via an opening/closing valve 40. A top of the tower 38 and the upper part of the unit 39 are connected via a check valve 41 in which a refrigerant can flow from the unit 39 toward the top of the tower 38 and a non-azeotropic refrigerant is sealed.
