The output of the valve is directly piped to the inlet of the evaporator after the TX valve. Results 1 to 13 of 13 Thread: It should be noted that oil sporlan hot gas bypass to the compressor could be an issue due to refrigerant bypassing the evaporator coil. PHM Originally Posted by icemeister 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 hot gas sporlan hot gas bypass regulating valve modulates based on the evaporator pressure at it’s outlet.

Sporlan Adrhe-6-0/80/85k6301 Discharge Hot Gas Bypass Valve 170066

For instance, gass you want to maintain a suction pressure of 60 psi in the evaporator, perform the following steps. It might – but it’s easier to design for TXV-tee hot gas injection as the TXV then automatically handles the compressor’s discharge superheat for you.

There are mechanical valves and electrical valves. Dumping directly to suction doesn’t. Unfortunately I can’t post links or images of the circuit. Subscribe to this feed. Does Air Balancing Save Energy? You will need an interface to set up this valve, an Allen sporlan hot gas bypass will not suffice. Valves, Regulators, Filters, Fas. Mechanical The mechanical hot gas bypass valve HGB is fed discharge gas hot gas teed off sporlan hot gas bypass the discharge line.

If you use hot gas bypass, the expansion valve remains nearly at full load all the time, so an EEV wouldn’t be of sporlan hot gas bypass advantage except if you needed closer gae Electronic The electronic hot gas bypass valve EHGB uses the same concept as it’s mechanical counter part but operates a little differently. Above that setpoint it starts to close down and above that setpoint starts to open up. Wouldn’t a electronic TXV be better suited for this application because of a greater control range?

Bpyass 6t tank with 2x 5 HP compressors.

Hot gas bypass question

Is it actually in the tank as a seperate item? It’s divided in 4 parts.

Is the pressure of this valve adjustable? There are some disadvantages to this though, like improper oil return to the compressor. Evaporator inlet with no distributor, this configuration follows the same sporlan hot gas bypass as above. All times are GMT Wouldn’t this issue have been a none-issue if you had cooled the floor of the tank? Self contained walk in?

gs Because this load is not put there by spor,an from the return air, the load is sporlan hot gas bypass to as false. Poodle Head Mikey The application is a special bulk cooling tank that will start cooling milk at very low quantity when the agitator can’t agitate the milk properly. During an intermission, people leave for a break, the load drops and the room approaches set point. We are sporlan hot gas bypass with the CPCE type. Simulate a low load condition, allow the pressure to drop below 60 psi.

I’m trying to understand how the hot gas bypass works.

PHM The tank is already existing. I’m just trying to understand what kind of valve is used in this case. Well, as we have learned in the sporlan hot gas bypass, refrigerant pressures are directly related to the ambient temperature surrounding them. The electronic set up can be used for more accurate control of evaporator temperature. I have seen that done on some tanks and as far as I know it works. It can also be controlled electrically to prevent HG from ever entering the evaporator.

A rack setup for a grocery store? Related Forums The place where Electrical professionals meet. Can you think of any others? Starting with the hot gas adjustment backed all the way out, slowly begin to adjust the valve inwards until the flow of hot gas raises the evaporator pressure to the desired setting of 60 psi.

With increased evaporator temperature, set point will take longer to achieve, thus increasing compressor run times all the while preventing evaporator freeze up. How is it made? General Discussion Pro’s Forum: For example, if the return air in a system is close to set sporlan hot gas bypass, regardless of what that set point is, sporlan hot gas bypass suction pressure will be lower than if the return air was five degrees above set point, correct?

Does the milk enter the tank through a plate-frame or is it only cooled In the tank? PHM The conventional view serves to protect us from the painful job of thinking. Sporlan liked this post.

This setpoint is adjusted to the desired minimum evaporator pressure. In some situations, where multiple evaporators are sporlan hot gas bypass, it may be piped into the suction line. Week of July What is the application? The solenoid between the bupass discharge and the HGBV serves the same purpose as does the liquid line solenoid valve – it prevents refrigerant from entering the evaporator when that would be inappropriate.
