For instance, if you want to maintain a suction pressure of 60 psi in the evaporator, perform the following steps. I’m trying to understand how the hot gas bypass works. You will need an interface to set up this valve, an Allen key will not suffice. The electronic valve can also be piped to the evaporator inlet or the suction line. For example, if sporlan hot gas bypass return air in a system is close to set point, regardless of what that set point is, the suction pressure will be lower than if the return air was five degrees above set point, correct?

I’m a controls engineer so I don’t have vast knowledge in refrigeration. I’m just trying to understand what kind of valve is used in this case.

If I may add to that, injecting hot gas after the expansion valve also maintains refrigerant velocity for proper oil return to the compressor. The only reason I can think of for using after-evap HG injection is convenience of installation. Hot gas bypass valves can be used in many different applications where the load on the evaporator varies, from yot, to server sporlan hot gas bypass, to process cooling equipment.

Sporlqn this issue have been ga none-issue if you had cooled the floor of the tank? The hot gas bypass valve opens putting a false load on the evaporator, since the evaporator temperature has been increased, the supply air serving sporlan hot gas bypass lecture hall will also be increased preventing set point to be reached.

PHM If I may add to that, injecting hot sporlan hot gas bypass after the expansion valve also maintains refrigerant velocity for proper oil return to the compressor. It’s 6t tank with 2x 5 HP compressors. Simulate a low load condition, allow the pressure to drop below 60 psi.

Building Science Discussions Pro’s Forum: The valve will maintain that set point by monitoring evaporator pressure and adding hot gas as needed. Can you think of any others?

What are you wanting to accomplish? Results 1 to 13 of There are mechanical valves and electrical valves.

With increased evaporator temperature, set bypaas will take longer to achieve, thus increasing compressor run times all the while preventing evaporator freeze up. Ybpass a space or process temperature reaches set point, hot gas can be added to the evaporator to raise its temperature.
