AI Technical Summary
Technical Problem
The refrigerant distribution at the inlet of the diversion component of existing HVAC equipment is uneven, and the gaseous and liquid refrigerants cannot be fully mixed, resulting in large flow differences.
Method used
A threaded structure is provided in the incoming flow pipe of the diversion assembly, and the threaded structure extends spirally along the axial direction of the incoming flow pipe, so that the refrigerant collides with the threaded structure during flow to generate mixed flow, thereby achieving sufficient mixing of the gas-liquid two-phase refrigerant.
Benefits of technology
The distribution uniformity of the refrigerant at the inlet of the diversion component is improved, and the heat exchange efficiency of the HVAC equipment is enhanced.

Abstract
The utility model provides a shunting assembly and heating and ventilation equipment, the shunting assembly comprises a distributor and an incoming flow pipe, the distributor is provided with an inflow hole and a plurality of shunting holes, and the plurality of shunting holes are communicated with the inflow hole; one end of the incoming flow pipe is communicated with the inflow hole, the other end of the incoming flow pipe is used for allowing fluid to flow in, at least part of the inner wall of the incoming flow pipe is provided with a threaded structure, and the threaded structure is constructed to spirally extend in the axial direction of the incoming flow pipe. According to the flow dividing assembly, the thread structure is arranged in the flow incoming pipe at the inlet end of the distributor and spirally extends in the axial direction of the flow incoming pipe, so that refrigerants in the flow incoming pipe collide with the thread structure to generate mixed flow when flowing, gas-phase refrigerants and liquid-phase refrigerants are fully mixed, and the flow dividing efficiency is improved. And therefore, the uniformity of refrigerant distribution at the inlet of the shunting assembly is improved.
