Inline Housing - Vapor Quality Sensor

Technical data: HBX-DX-IN / HBX-CR-IN 

HB products has developed the unique vapor quality sensor, which is the only sensor able to directly measure the liquid content of liquid in the evaporator output. The sensor works both in pump circulated and DX systems and can optimize the efficiency and capacity to a new level.

Evaporator control
The optimal evaporator is not filled with liquid refrigerant like you often have in pump circulated refrigerant systems with circulation ratios above 1.5. The optimal evaporator is not dry like a lot of superheat-controlled evaporators.
By measuring the liquid content in the evaporator output and using this measurement to control the liquid feed.

Most refrigeration systems operate most of the time in part load and especially during part load the efficiency is typically rather poor and can be optimized significantly. Pump circulated systems fills the evaporator with liquid which reduce heat transfer by 50 % and increases the pressure loss which increase energy consumption. For pump circulated systems an energy saving of minimum 20% is typical for optimized systems, and much more on systems without circulation control.

In DX systems a larger part of the evaporator is used for superheating and the superheat is increased which reduce capacity and increase the power consumption dramatically. We have documentation showing an energy saving of 20% during full load and 50% during part load for a DX ammonia system. Link to the documentation.

Inline
The straight version called Inline is available from 1” to 2” and the sensor accepts flow in both directions. The pressure loss in the sensor is very low due to the straight flow and smooth internal design. Mounting can be both horizontal and vertical position. The sensor is made in stainless steel and can be butt welded (TIG) or brazed into the system.
