Problems solved by technology

On the one hand, this will affect the heat transfer effect of the evaporator, and on the other hand, the accumulated refrigerating machine oil in the flooded evaporator will cause the compressor to lose too much oil and fail to work normally or be damaged. Therefore, other methods must be used to assist return oil

Abstract

The invention discloses an ejecting oil scavenger of a flooded evaporator for a screw water chiller. The ejecting oil scavenger of the flooded evaporator for the screw water chiller comprises a base (1). A cavity is formed inside the base (1), and the front portion and the rear portion of the base (1) are connected with a nozzle (3) and a hybrid tube (4) respectively. An opening in the tail portion of the nozzle is communicated with the front portion of the cavity (2), and an opening in the head portion of the hybrid tube (4) is communicated with the rear portion of the cavity (2). A drain tube (5) is arranged at the bottom of the base (1), and the drain tube (5) is communicated with the bottom of the cavity (2).

Description

technical field [0001] The invention relates to an injection oil return device of a flooded evaporator of a screw chiller. Background technique [0002] At present, the oil return method of the flooded evaporator of the screw chiller has three methods: direct oil return design, manual oil return design and gas injection oil return design. Using gas ejection oil return screw chiller, (1) The flooded evaporator ejector has a simple structure; (2) The oil content in the flooded evaporator can be controlled at 1%. The oil return problem of the flooded evaporator is a key issue in the design of chillers, and it is far from enough to reduce the oil return pressure of the flooded evaporator by using a high-efficiency oil separator. The refrigerant HFC-134a used by all manufacturers of screw chillers at home and abroad is compatible with synthetic refrigeration oil in the condenser and evaporator, and a small amount of lubricating oil brought into the flooded evaporator is not idea...
