    It was only 88 degrees outside here, but even with my a/c unit pumping out it was 99.5 degrees in the midpoint of my trailer (I keep the thermometer halfway between the grill at one end and the air conditioner at the other end).

    Two weeks ago when the outside temp hit 104, the inside was 109. The only saving grace is that if you stand directly under the air conditioner vent, it is actually comfortable.

    so from your experience today, hood temps are actually a lot less then we all assumed they were.... very cool :)
     
    thank you very much for the time and effort!
     
    hahaha, thats an awesome pic of the dog :)

    Please keep in mind I had minimal equipment running, no char broiler, no flat top, no deep fryer and those are the killers when it comes to heat, smoke and interior temps. Others on the forum that use those pieces of equipment could do a better study than mine. I didn't mention a name because I don't want to assign a task LMAO. Ok Chef..........lol

    Me????....
    I'll look into temps tomorrow if I'm sittin around with my thumb you know where.....Everythings prepped, all I have to do is show up 30 min ahead to fire up all that heat producing equipment.
     
    Last time I checked, it was 109 inside this weekend, outside was around 82.

    You guys need bigger CFM from your hood fans. We have no AC in the trailer and it felt cooler in the trailer when it was 103 out side in our heat wave 2 weeks ago.

    My exhaust fan pulls so hard as it is that it sucks the bottom of the garbage bag up to the top of the trash bin until we get enough trash in it to weight it down. So I don't thing CFM is the problem. I could be wrong but I don't think so.

    From the temp given, I think there are dead spots with little air movement.   The hood temp is cooler that the rest of the truck.   The truck temp should be about the same as the outside temp.     So the air must be flowing straight from the window/vent to the hood and very little flow thru the truck.   You might try regulating the flow so air goes thru the 'whole' truck.
     
    Also, the roof temp, I assume that is the inside temp at the roof????  Question, is the roof insulated?

    "The roof temp, I assume that is the inside temp at the roof????  Question, is the roof insulated? "
     
    The roof temp was taken from the very top inside of the hood. vs The hood temp was taken at the filters where the air flow is greatest.I'm not sure I should have done it that way but I noticed there was a significant difference in temps so I wrote them down.
     
    The inside temp was taken at ceiling height.

    Chef, your 109 inside with a outside temp of 82 will give everyone a much better idea of trailer truck temps than my post. Please be sure and list what your running so the new people and builders can get a real feel for what they are facing.
    Thanks

    I am running the big ugly mushroom fan on the roof. It is variable speed but to change it I need to get up there under the cover. Stainlesskitchenhoods.com engineered the fan. I have not taken any temp measurements so maybe it is the airflow through that is helping - window positioning like edwmax was refering to. I have the 4' concession window, (3) very small 10" x 14"frv windows, and (1) rv roof vent in a 20' trailer. The trailer is insulated with 1" or the pink foam board. I do know that if the fan is on and the windows are closed you have a very difficult time opening the door from the suction.

    i really do think its the radiant heat that is kicking the heat up..... i wonder what the temps would be if a "shield" was placed between the cooking area and the operator during slow times..... i realize this is realistically not a viable idea, but heat transfer should be able to be managed......
     
    maybe locate some make up air at the lower front of the big offenders, and create an air curtain of sorts to soak up as much as the radiant heat as possible before it migrates into the truck....

    My temps are not as thorough as the Dr's, but at the window hovered around 100-104, the hood temp was 123 + -, dependant on if the fryer was cycling.
    I only had half the broiler running today also.
    It was 83 today.
    I have been bitching about the heat in the kitchen for 30 years, it's part of the job.
    If I didn't like it, I would have become a butcher and then been bitching about working in a 34 degree cold room 8 hrs a day.
    You know the old saying....

    with the a/c on it was at 93 degrees with the warmer and refrigator on and 97 outside with a heat index of 103. Before I got my new generator and was able to use the a/c, 103 outside,110 inside with fans running. Oh the old generator, the main shift bearing locked up and fellout of the seat and the armature slid forward and out of the field and stop producing power. $1400.00 dollars later at Lowes and wal la,,,power.

    In addition, I think refrig, salad/sandwich prep, & drink coolers (ect)  are dumping their heat into the truck-trailer.   These could easily be vented to the outside thought the wall behind the unit  ... drier vent.    If these are close to each other, then the vent space could be closed off and a small fan used to draw air and vent to the outside.    ... I think this may give the added advantage of lowering power usage & increased efficiency of the equipment.

    The (2) ice cream dipping cabinets in my trailer throw a ton of heat. When we first opened we were closing the windows at night and turning off the hood vent. It would get very hot in the trailer over night - at least 25 degrees warmer inside than outside. We quickly learned to keep open the small windows and the roof vent. In the summer heat we leave the hood fan on over night to keep the dipping cabinets from working against themselves. It would be much less expensive to replace the motor in the hood fan than repair a dipping cabinet refridgeration system.

    Just my point about equipment waste heat.   These usually depend on convection current within the Room to cool the coil, but with a little effort the hot air could be vented outside.

    But then your still sucking out some of the air conditioned air at the same time. I promise if that were a plausible idea every fast food chain in the country would be doing it. They have access to the best commercial kitchen design engineers, and spare no expense in kitchen layout, design and equipment choices. And if a company that builds restaurant equipment thought that would work they would design it, produce it and for at least a few years (until the others caught up ) take over the  kitchen equipment sales market.
     
    I can see the ads now:
     
    Our equipment will reduce the temperature in your
    BOH by 33 1/3 %. Save thousands in air conditioning
    cost and reduce equipment maitanince by 25%. Pays
    for it's self in savings over 7 years. And your staff will
    stop grumbling about the heat.

    thats exactly what i am thinking..... leave the intake on the inside(in my case down south, up north have it vented from outside) and vent the discharge side to the outside..... would mean a couple more vents located on outside of truck (or under the truck if its a bottom discharge)
     
    i think the benefits would far outweigh the minor additional cost....
     
     
    as an example, the room my computer is in is usually 5 degrees or so warmer then the rest of house because i have a water cooled processor that is constantly pumping out warm air, the static heat from a 17" flat monitor, and whatever minimal heat is coming from a laser printer, and my computer and phone modems....

    'Good' Kitchen designers & Engineers are doing actactly that.    ... Especially where the equipment is in enclosed cabinets.    Some residential kitchen designers are venting the 'hidden' appliances to the outside rather than into the AC conditions space.    ... Otherwise the addition heat load must be added as addition AC cooling load.    ... In commercial construction, the Codes call for a minimum of 'fresh' (outside) makeup air. In these 'designed' kitchens fresh air is piped into the kitchen  to replace the exhausted air and off-set the Code required minimum fresh make up air and help reduce excess lost of AC conditioned air from the dinning Rm.
     
    All I was pointing out, this equipment in truck/trailer concessions are sitting against the outside walls.  It would be easy to add vents & small fans behind each to vent the hot air from the cooling coils.

    The specs on my Dipping cabinets require them to be 4" min from the walls. I actually re-arranged my layout last minute to accomodate this. The on-line specs did not show this so I did not know until the actual units arrived. I got lucky and the changes worked out for better workflow anyway.

    Chicnscoop,
    do your dipping cabinets have intake or outlet vents on the back ? 
    if so by venting it through the wall you could have still placed it right up next to the wall im thinking..

    I leave the a/c on all night, when I get to the trailer it's 67 degrees@ 4:15 a.m. and about 80 degrees outside, fire up the grill, fryer, steam table, coffee pots,  juice machines,micro wave, 2 burner stove, and in about 15 min. its 80 degrees in the trailer with the over head on,and yes also mine will suck the walls in if everything is closed up. temp  only goes up from there i dont have any hood temps or anything cept to know its HOT, in side temps get into the 110 range and thats not in the heat of the day  fortunatly we leave @ at about 1:00 p.m. close the window at 12:45 p.m. but from 5:45 - 12:45 everything is running full bore.

    There has to be a way to lessen the heat. How can you guys work like that?  Can you build a plenum behind/under your equipment  and duct the heat to it with a dedicated exhaust fan to pull the heat out (and up)? Sorta like a heat distribution duct system in reverse. Or maybe place a thru the wall fan behind the heat producing part? But, most likely, the thru the wall fans would blow hot air on the customers. I can't believe no one has figured out a solution to this. I am so glad we don't have a huge heat producing griddle. Our little single gas burner/12" griddle pan and the tankless water heater generate enough heat.
