I have a feeling your air conditioner is too small to cool it off much more than that. We use a 24,000 btu.
I think so too.... ran it without the calf and it was in the mid 50's within a half hour... would I be able to take the air conditioner back? how big is your room and how many calves do you have for a 24,000 btu?
First off, where did you buy your Coolbot? It should have come with a installation diagram. I know that you are having trouble with it not working and asking questions is good, but you have a brand new piece of equipment that isn't working (or you think it isn't). Those things are $300. Call the people you bought it from.
If you bought it used, call Matt @ Calf Climate. I would be really surprised if he wouldn't talk to you. He designed our cooler and sold us all of the stuff for it. 217-417-7784.
We run 2-25,000 btu window AC units in a 10X25 cooler. That is 50,000 BTU's in a room that holds 3 fat steers. It is sealed up and insulated to about R24+ with no exposure to any outside walls. We will occasionally run as many as 3 Sullivan Turbo Fans. We can pretty easily keep the temperature at 45 degrees in the hottest part of the day. We can get it in the high 30's if we want to, but WE end up sick if we get it that cold in there.
I am no expert on this, but I have to agree with the others that have suggested you don't have enough AC unit. If you decide you need more AC unit, send me a PM and I will send you a link to a wholesaler that can ship you a factory refurbished unit cheap. For one steer, you need about 12,000 BTU's in a sealed room if you want to really get it cold.
