Hood design dilemma - kitchen designers please help
Comments (13)Holly are you saying i have to replace all of the crown in the kitchen? I am not trying to save anything between the 2 windows where the range area is currently. I am ok with the expense and have already gotten the quotes from the cab company and for the modernaire hood insert. But for the cost I want to be sure want to be sure about not using the vv96 in that area and the staggered cabs. I know what I have is really nice, it is just not what I want....See MoreRange Hood duct length problems! Please Help!
Comments (2)Any blower that is not positive displacement (like an air compressor piston) has what is called a fan curve (see below). This curve relates flow rate to pressure drop across the blower. If duct length pressure loss plus hood filter pressure loss plus make-up air pressure loss uses up much of the pressure capability of the blower, flow rate will drop quite a bit. But there is hope because depending on relative characteristics, a supplemental blower in the duct path or externally wherever the duct exits will share some of the pressure drop, causing the flow rate to rise to where is hoped to be. Now, the air flow has to be the same through both blowers, so their respective fan curves have to be consulted and blowers tuned, perhaps, to work well together. This solution is better applied when an inadequate installation already exists. The easier approach is to buy a better blower (higher pressure loss capable blower) and use it instead as a single blower. Overall, the solution is situational and not amenable to glib advice.Example fan curve....See Morevent hood ducting dilemma -- please help!
Comments (6)Devious and small duct paths have a lot of pressure loss. While it is possible to find a blower that can handle any combination of flow rate and pressure loss, you might not want to pay for it. If I wanted to go out the back of a hood and down the wall, I would peel the sheetrock and redesign the stud layout (as for a window, say) such that there was room for a reasonable duct cross section. This is where someone familiar with carpentry is needed, along with plumbing and electrical support. You might need wire splices along with the required accessible boxes for the splices. The plumbing scope and feasibility is not internettable (as Sophie puts it), although if you tear the wall open and provide photos we would surely be willing to comment. :) You would probably need to end up with wall access panels within your cabinets to pull off a lot of pipe, cable, and stud rerouting....See MorePlease help! Do I center my hood and range with the island?
Comments (1)I would prefer the more balanced work space over arbitrary symmetry to an offset island. Plus, you don't want the stove and sink aligned if somebody might be working at each of them at the same time. Maybe a single pendant, over sink? or interesting semi-flush lights, if your hood and tile really merit center stage? (most are not *really* as dramatic as all that...)Hanging the lights a little on the high side seems to be a common solution... Also keep in mind that as you move about the room, different elements will be prominent to your eye, so it's ok to have lights that cross the visual of the hood, especially if you need the task lighting. They too are a thing to enjoy....See Morekaseki
