Walk-in Deer Cooler

[gravity]

he wants it close to 40*

[shaka]

I don't think that's going to happen

Unless its. 40F outside

[gravity]

whys that ?

[shaka]

You got 4000 btu

You need around 7-8000
On 4 inch walls of insulation

Your suction psi doesn't seem bad yet your SH is high. Head a little low too. Maybe not enough capacity!!

[shaka]

If he is your buddy
Try to look for a 2 fan evaporator coil
Then put an used AC condenser
You can get it beer can cold

[gravity]

i have the txv stem adjusted all the way out and it still has high superheat.

if i dont have enough capacity then this would be a high load.

i thought higher load would be higher pressures. or just higher superheat?

[gravity]

1.5ton a/c with a 18,000 btu evaporator?

[gravity]

if u say i can get it 40* then i will get to hookin it up.

[shaka]

Hvac is rated at 40f coil witch is 1 ton =12000 btu
At 20-25F coil it's approx 7,500 per ton

[shaka]

You need a real refer coil not AC
2 fan.

[gravity]

yea, i figured that much. so a 1.5ton r-22 condenser would be about 11500 btus. so i need a 12,000btu 2 fan evap

I thinking you got a larger evap than the little condensor can handle. Could be wrong!!! WHy did you install a 1/3 HP? What's the BTU rating of the evap?
