Problems solved by technology

[0003] At present, the oil temperature control and oil return system are realized through independent devices. The oil temperature control usually uses a heat exchanger to cool the liquid from the condenser, and usually uses an oil cooler or an oil return device: a separate When the oil is returned by thermosyphon, the coolin

Abstract

The invention relates to an ejecting thermosyphon multifunctional oil return device for a heat pump unit. The ejecting thermosyphon multifunctional oil return device comprises an evaporator, a cooling heat exchanger, a compressor and an ejector. The evaporator is sequentially connected with the cooling heat exchanger and the compressor through a refrigerant liquid inlet pipeline; the ejector is respectively connected to the evaporator and the compressor through pipeline connection; the cooling heat exchanger is connected with an oil tank and further connected with the ejector through a cooling electromagnetic valve; a bypass electromagnetic valve is arranged between the ejector and the refrigerant liquid inlet pipeline, and the ejector is further connected with a condenser gas pipeline through a condensed gas electromagnetic valve; and a lubricating oil detection device is arranged on the cooling oil pipe between the compressor and the cooling heat exchanger. Oil temperature control and system oil return are achieved at the same time, the cost can be reduced, and the compressor efficiency and the system performance are improved; and lubricating oil entering the compressor is detected online through a viscosity detection device, so that the temperature of the lubricating oil entering the compressor is adjusted in time, and the lubricating effect of the lubricating oil is guaranteed.

Description

technical field [0001] The invention relates to an oil return device, in particular to a jet thermosiphon multifunctional oil return device used for a heat pump unit. Background technique [0002] In heat pump units or similar heat pump units, it is necessary to inject lubricating oil into the compressor to achieve the functions of lubrication, cooling and sealing, so as to ensure the efficiency of the compressor and the reliability of the unit. Most of the lubricating oil entering the compressor is sprayed into mist And under the action of pressure, the refrigerant enters the exhaust pipe and then enters the system. Due to the large pressure ratio of the heat pump unit and the high exhaust temperature, the oil temperature will also increase and the viscosity will decrease. At this time, the oil temperature needs to be obtained. It is very well controlled, and the lubricating oil entering the system also needs to return to the compressor in some way, otherwise long-term oper...
