I thought a good rule of thumb was between 500 to 700 square feet per ton. Can any of you HVAC gurus help?

That "is" a rule of thumb, but it is not a "good one"! As Wayne was possibly trying to allude to, you cannot terminate tonnage by square footage. There are a whole lot of other factors that are more important. When you build the same type of house in the same weather zone you can "assume" that a certain tonnage will handle a certain amount of square footage. If you have a two-story house with 50% less square footage on the second story than on the first, would you put a HVAC unit on the second floor 50% smaller than the first floor? The first floor has a buffer zone in the crawlspace or basement below. It has a condition space above, so the major heating/cooling load is the perimeter walls. On the other hand the second floor as a buffer zone below (the conditioned first-floor).

It also has the perimeter walls as a primary load (like the first floor). But the ceiling is against an attic that gets how hot? The roof above that attic is a solar collector and radiates, how much energy? There is thermal bridging issues with the roof framing and thermal bypass issues with the ceiling penetrations for electrical penetrations (thus significant air leakage). Hot air rises, so a significant amount of the first-floor cooling load may pass upwards into the second-floor zone and increased the load on that equipment… With this in mind, do you still feel that square footage per ton on the first floor is equivalent to the square footage per ton on the second floor?

The sizing for a heat pump in FL is all about the cooling but up here its all about the heating when on a slab foundation. I had to select my heatpumps for proper heating which ended up being a little large for the cooling calcs but they still run enough to remove the humidity. Main Line Inspections, Inc. National President / NACHI (2003-2004) NACHI Education Committee Member PA NACHI Certified Inspector # 01102902 Delaware Licensed Home Inspector # H4-071Commercial refrigeration systems in the US are mostly rated in tons of refrigeration and this term is used widely in other parts of the world. However, outside the US, cooling systems may be normally specified in kW (or MW) or in Btu/h. The roots for refrigeration are in the ice making industry, and the ice manufacturers wanted an easy way of understanding the size of a refrigeration system in terms of the production of ice. If 288,000 Btu are required to make one ton of ice, divide this by 24 hours to get 12,000 Btu/h required to make one ton of ice in one day.

This is the requirement for the phase change from liquid to solid — to convert water at 0°C (+32°F) into ice at 0°C (+32°F). As a practical matter, additional refrigeration is required to take water at room temperature and turn it into ice. To be specific, one ton of refrigeration capacity can freeze one short ton of water at 0°C (32°F) in 24 hours. So, a ton of refrigeration is 3.517 kW. This is derived as follows: The latent heat of ice (also the heat of fusion) = 333.55 kJ/kg = 144 Btu/lb One short ton = 2000 lb Heat extracted = 2000 x 144/24 hr = 288000 Btu/24 hr = 12000 Btu/hr = 200 Btu/min 1 ton refrigeration = 200 Btu/min = 3.517 kJ/s = 3.517 kW = 4.713 HP A much less common definition is: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0°C in 24 hours. Based on the heat of fusion being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW. Thus, 1 tonne of refrigeration is 10% larger than 1 ton of refrigeration.
