Determine the weight of the shipment in pounds. Divide the weight by the total cubic feet of the shipment to get the pounds per cubic foot, or density. For multiple pieces, add the total weight of each piece before dividing by the total cubic feet. Once you have the freight density, use...
Have the HVAC contractor measure square footage to determine Btu and tonnage requirements. You’ll want an appropriately sized unit for the best energy-efficiency and cost. Check fuel sources. If your home has gas lines, for example, you might choose a gas furnace because it will require less...
Example: Carrier A/C Compressor Condenser Model# 38XD12400 (same unit as used for the serial number example above), there is variation in how Carrier assigned these numbers but typically the numbers indicate either tonnage or MBTUH. This example has digits in the 4th and 5th positions (...
The total demand for freight transport in Europe has increased significantly in recent decades, but most of it has been handled by road transport. To fulfil the modal shift targets set in the EU White Paper 2011, it will be necessary to double rail’s market share from today’s 18 %, by...
Simply put, it’s the capacity or power of the AC. The bigger the BTU, the more cooling effect an AC unit can provide. Here is an example of how you can calculate how many BTUs you need to cool down a 500 sq. ft. area with 8 feet ceilings, average sun exposure, average climate...
