Refrigerant Distributor

Refrigerant Distributor Description

Refrigerant distributors are critical components in HVAC and refrigeration systems, ensuring that refrigerant is evenly distributed to the multiple circuits or pipes of the evaporator coil.

How it Works

  • The distributor has an orifice or nozzle inside that meters and directs the flow of refrigerant.
  • The refrigerant enters the distributor body and is then divided into multiple small tubes, each of which leads to a different evaporator channel.
  • Excellent distribution ensures that each heat exchange coil circuit receives the same amount of refrigerant, resulting in efficient operation.

Function

  • The refrigerant distributor evenly divides the liquid and vapor refrigerant mixture from the expansion device (such as a TXV or electronic expansion valve) into several smaller tubes that deliver it to the evaporator coil.
  • This ensures even refrigerant flow and consistent heat exchange across all coil circuits, preventing uneven cooling or frost buildup.

Refrigerant Distributor Type

1 Distributor Venturi Type

After the gas-liquid mixed refrigerant enters, it first contracts slightly, the speed increases, and the pressure decreases. After reaching the narrowest point, the channel becomes larger, the pressure increases, and the speed decreases. Like a nozzle, the refrigerant is sprayed into the distributor. At this time, the pressure is relatively high, and the refrigerant flow rate is fast and very uniform.

2 Distributor Pressure drop Type

There is a throttle hole inside the liquid distributor. When the refrigerant passes through, the pressure will drop, which will increase the flow rate and generate turbulence. The turbulence will cause the refrigerant gas and liquid to mix fully, and then accelerate the flow to the distribution pipe to achieve uniform distribution.

3 Distributor Centrifugal Type

Mainly by making the refrigerant produce centrifugal motion to fully mix the gas and liquid, allowing the refrigerant to evenly reach every distribution pipe.

Refrigerant Distributor Nozzle

Refrigerant distributor nozzles are precision orifice components within the refrigerant distributor that control the flow of refrigerant before it is distributed to multiple evaporator circuits.

Refrigerant Distributor Guide

As its name suggests, flame brazing is a process that uses flames. A flame is a source of heat that aim to increase the temperature of the substance it touches to a sufficient degree to allow an operation to be carried out. Flame brazing can also be referred to as torch brazing. It can be either manually, mechanically, or automatically performed.
