Heating and humidification

If you're so smart, give the damn answer

Can’t speak for LG’s heat pump chillers but I’ve worked on Aermec’s line. These things are garbage. Can’t maintain HW setpoint.

Dope

Must feel great standing there. Thank you for the knowledge

Bad txv

How do you do that?

it was william cullen not james , and he invented it in 1756 . long before the patenting process was important . Although Cullen's work laid the groundwork for refrigeration, it wasn't until the 19th century that practical applications emerged. For instance, in 1842, American physician John Gorrie built a machine to create ice to cool down patients with yellow fever in a Florida hospital.

Amen God is merciful the buidings where turn down but most lives where spared and that's important thing.

Fine example of buiding can be replaced but people cannot

People should be thanking the lord for he is mercy in not killing everyone,he could of easily done that and his angry is unimaginable,these Disasters that's happening around the world is just little snippets of it.

Good job

Add a steam system

heat and humidify

One cool thing Trane did was test condensers with larger evaporators which had a remarkable effect on moisture levels

Thanks

Wow interesting!

Whats the corrolation between this and vapour pressure deficit?

NICE! CON-DEN-SATION

Well your going to have to heat it, but the dp will drop. So you need a humidifier to raise the dp.

More please 🫶

i’d add 40F DB and 17.5F DP !

That's funny. 😂😂

What kind of meter is that?

tell them they have a hole the size of a golf ball in the heat exchanger and it needs replaced

Good god I’ve been in HVAC my entire life, and things like this just make me feel like a dumbass tinknocking monkey 😂 This is why I’m going to school though, thankfully my union is pushing HARD to get all the guys up to speed. I may not know everything right now, but hoping to get there.

As a marine upholstery expert I am qualified enough to say you’re speaking Spanish to me right now. 😂

14.81-2.25 Btu/lb=12.56 Btu/lb total load Sensible load= 11.9 Btu/lb Latent load=0.66 Btu/lb For providing sensible heat, based on building classification a direct or indirect fired heater will be chosen based on the formula BTUH = (Sensible load) x (density of air based on elevation above sea level and temperature mean) x (volume of air to be supplied per hour). For humidification, 18.64 grains of moisture needs to be pumped per lb of air into the space. So density of air x volume of air per hour x 18.64 = total grains of moisture needed per hour. This grains of moisture can be used to select an appropriate sized steam humidifier, possibly with a multisteam distributor in the duct.. Let me know if the calculations are accurate enough.

Thank you! This helped make it easier to remember through logic and helps keep the units straight in my head!

Haha

this is what i thought but then i dont understand why people say higher dew points make mold more likely? Like states like florida where its high humidity but also higher dew point? I thought if the dew point was higher that means its less likely to get condensation indoors? Which would be better for preventing mold growth?

Bring in 32 and 1/2 cows.

Phoenix Controls High speed Actuator for a their signature venturi valve.

Common at Publix. I think it’s for air balance reasons because the return is tied into the main floor

Sensible heating to db=82, then humidify at constant wb=54 until db reaches 70, at which point dp=40.

Thankyou im watching this before i start my program very easy to follow🙏🏾

Gas furnace with a steam humidifier

Heating & humidification

Thanks, Iron man

use for free cooling in the colder months

Wever hooked up an electric heater in line with an erv to do this exact thing the heater went on the inlet or the erv. In another situation we used a water to air heat exchanger in a duct system with a temp prob to control for a all year mua system
