BTU is how much heat is produced at one instant, BTU/hr is the amount of heat produced in an hour. MBH is 1000 BTU/hr. However, BTU is sometimes used as an equivalent to BTU/hr, so the conversion might work. Wikipedia has an article that might clear things up. 1 MBH = 1000 BTU/hr. Thousand BTUs per Hour (MBH).

He asked the difference between BTU and MBH. BTU is a measure of energy, and Mike gave you the derivation. A BTU is comparable to a Joule in the metric system. MBH is thousands of BTUs per hour (we especially love compound TLAs.) It is a measure of power (energy per unit time,) and it's comparable metric unit is Watts.

2023年9月13日 · MBh units should help with the cost estimate of running your air conditioning (AC). It's a measure of the heating/cooling capacity of AC equipment. MBH - One MBH is equivalent to 1,000 BTU's per hour.

MBH = 1000 Btu/hr = MBTU/Hr = MBTUH I've seen it written many ways, but they all mean one thousand British thermal units per hour. Divide BTU/Hr by 1000 and you get MBH. A British thermal unit (BTU) is the amount of heat required to raise one pound of water 1 degree F.

2023年9月14日 · MBH [ thousands of BTUs per hour] is an expression for the rate of energy consumption or production: M is for thousands, B is for Btu's (Brittish Thermal Units) and H is "per hour" . ie: 860,000 ...

My HVAC guy wants to install the 150 MBH Lochinvar Noble. When I asked him why he wanted to bump up to the 150 instead of the 110 MBH Lochinvar Noble, his response was, "Well, with the 10:1 turndown ratio it really doesn't matter, and I once installed one that was too small and I regretted it." Well, I wish I could just accept that.

HVAC-Calc loss is 77 mbh; my "adjusted" loss is 68 mbh. "Adjusted" loss is good enough to predict the surface temp of my standing TRVd iron rads to a degree during maintenance conditions. As best as I can determine, the actual gas used at outside design temp agrees with adjusted loss--that is if the nameplate, my estimate of transmission losses ...

2003年10月1日 · The HVAC company has installed 2 high velocity a/c units with hot water coils. The 600 cfm units each have a capacity of 59.4 MBH with a water flow of 4 GPM up to 62.4 MBH with a water flow of 8 GPM. Both are rated with entering water @ 180 degrees. The third conventional unit is not installed yet but I assume the specs will be similar.
