    摘要： A chiller according to the present invention comprises: a compressor for compressing a refrigerant; an oil separator for separating oil and the refrigerant discharged from the compressor; a condenser for condensing the refrigerant passing through the oil separator; and expander for expanding the refrigerant condensed in the condenser; an evaporator for cooling cold water with the refrigerant expanded in the expander and connected to a demanding place via cold water pipes; an ejector for partially passing the refrigerant compressed in the compressor and connected to the evaporator via an evaporator oil recovery path; an oil recovery path of the oil separator connected in such as manner that the oil leaked out of the oil separator passes through the oil recovery path so as to be recovered to the compressor; and an ejector outlet path connected in such a manner than the oil and the refrigerant leaked out of the ejector passes through the ejector outlet path so as to be recovered to the compressor. The oil recovery path of the oil separator and the ejector outlet path are disposed to be able to exchange heat. Therefore, it is possible to lower the temperature of the oil which has been recovered at high temperature via the oil recovery path of the oil separator is lowered. In addition, the liquid refrigerant which has been recovered via the evaporator oil recovery path is gasified in the evaporator. Therefore, it is possible to prevent the damage to the compressor and increase the efficiency of the compressor.

    摘要： Provided is a scroll compressor, which includes a stationary scroll including a first wrap, an orbiting scroll including a second wrap, wherein the orbiting scroll and the stationary scroll are disposed to have a phase difference therebetween, and a compression room is formed between the first and second wraps, an inflow part for introducing refrigerant into the compression room, a first introduction part disposed on a side portion of the stationary scroll to inject refrigerant into the compression room, and a second introduction part disposed on another side portion of the stationary scroll to inject refrigerant into the compression room. Pressure of the refrigerant injected by the second introduction part is different from that of refrigerant introduced into the first introduction part. The second wrap moves while the orbiting scroll orbits, and opens the first introduction part before the introduction of the refrigerant through the inflow part is completed.
