Patent ID: 7513128

Claim:
An ejector-type cycle for exchanging heat using a refrigerant, comprising: a compressor for compressing the refrigerant; a condenser for condensing the refrigerant compressed by the compressor; a first orifice arranged downstream of the condenser to expand the refrigerant; an ejector arranged downstream of the first orifice and capable of exhibiting a sucking ability at an inlet thereof with the refrigerant passing through a nozzle of the ejector; an evaporator for exchanging heat with an external fluid by passing the refrigerant through the evaporator and having a refrigerant outlet connected to the inlet of the ejector; a dryness degree adjusting mechanism interposed between the first orifice and the ejector and connected to the ejector and the evaporator so as to supply the refrigerant thereto; and a second orifice arranged downstream of and connected to the dryness degree adjusting mechanism and arranged upstream of and connected to the evaporator; wherein the dryness degree adjusting mechanism is located downstream of the first orifice and divides a refrigerant inflow into a first refrigerant outflow and a second refrigerant outflow; the first refrigerant outflow is supplied to the nozzle of the ejector; and the second refrigerant outflow is supplied to the second orifice.
