Problems solved by technology
[0002] The two-stage compression system has the advantage of being able to operate stably for a long time in an ultra-low temperature environment, but it also has the problem of low cooling efficiency. One factor affecting the cooling efficiency is: the exhaust gas of the first-stage compression cannot be effectively cooled to a saturated state, so when it is compressed again increased power consumption
In the related technology, in order to improve the refrigeration energy efficiency of the two-stage compression system, the exhaust gas of the first-stage compression is cooled to a saturated state to increase the refrigeration efficiency, but the exhaust gas of the first-stage compression has a high oil content, which affects heat transfer after entering the evaporator side. room for improvement

Abstract
The invention discloses a refrigerating device. The refrigerating device comprises a compressor, a reversing assembly, an outdoor heat exchanger, an indoor heat exchanger, a flash device and an oil separator. The compressor at least comprises a first-stage compression cavity and a second-stage compression cavity. The first-stage compression cavity is provided with a first air suction opening and a first exhaust opening. The second-stage compression cavity is provided with a second air suction opening and a second exhaust opening. The reversing assembly comprises a first valve port, a second valve port, a third valve port and a fourth valve port, the first valve port is connected with an exhaust opening of the compressor, and the fourth valve port is connected with the first air suction opening. The outdoor heat exchanger is connected with the second valve port, and the indoor heat exchanger is connected with the third valve port. A first throttle element is arranged between the flash device and the outdoor heat exchanger, and a second throttle element is arranged between the flash device and the indoor heat exchanger. The oil separator is connected between the first exhaust opening and the flash device and connected between a second air suction opening and the flash device. According to the refrigerating device, the exhaust oil spitting rate of the low pressure side is low.
Description
Technical field [0001] The present invention relates to the field of refrigeration, and in particular to a refrigeration device. Background technique [0002] The two-stage compression system has the advantage of being able to operate stably in the ultra-low temperature environment for a long time, but it also has the problem of low refrigeration efficiency. One factor that affects the refrigeration efficiency is: the exhaust gas of the one-stage compression cannot be effectively cooled to a saturated state, so when it is compressed again Power consumption increases. In related technologies, in order to improve the refrigeration energy efficiency of the two-stage compression system, the exhaust gas of the first stage compression is cooled to a saturated state to increase the refrigeration efficiency. However, the exhaust gas of the first stage compression has a high oil content, which affects heat exchange after entering the evaporator side. Room for improvement. Summary of the...
