The hot gas bypass valve is a mechanical valve used to introduce a false load into the evaporator and used on systems with varying loads, process chillers for example . As well as mechanical, it can also be installed in an electonic version. For more info, check out hvacknowitall.com.

ohhhhhh to keep the evaporator from icing up is one really good reason ;)

Found one leaking through regardless off the adjustment position. Any tips before condemning?

Loki smoke a sporlan valve. Is there a specific like size you would use I am looking for one for a 410-a 5ton system.

Question please, If the valve goes bad. Is it possible the compressor would overamp and possibly give symptoms of a lock rotor?
@HVACKnowItAll
@HVACKnowItAll 10 месяцев назад
Not likely no
@CreativeMaintenanceSolutions
But the question is why? This video was perfect in explaining what is happening, but WHY? What the purpose of introducing a false load to the evaporator? Thanks ahead of time.

You never explained why does the evaporator coul need a false load on it. Can you explain

Why not just have a regulator on the suction line since this is an energy penalty?
@scottm3552
@scottm3552 3 года назад
Do you adjust the valve under a low load?
@HVACKnowItAll
@HVACKnowItAll 3 года назад
Correct!

Wouldn’t using a EPR valve be better?
@HVACKnowItAll
@HVACKnowItAll 2 года назад
EPRs maintain a set pressure, hot gas bypass valves prevent the pressure from dripping lower than wanted only in low conditions, not at all times.
@zoidelux
@zoidelux 5 лет назад
Is this the same as an EPR?
@HVACKnowItAll
@HVACKnowItAll 5 лет назад
no, an epr piped into the suction only, it does not utilize hot gas to create a false load

Hi, does it staticly bypass some coolant or does it dynamicly change?
@charlesb7418
@charlesb7418 4 года назад
Discharge gas from the compressor is diverted from or bypasses the condenser and goes straight to the evaporator
@paradieshenne
@paradieshenne 4 года назад
@@charlesb7418 and how is it controlled? Do you set a constant threshold or is it regulated by temperature/pressure?
