12,000 BTU equals 1 A/C Ton.
4800 btu's, ton = 1200 btu's
24,000 btu
18000 btu or 1.5 tons.
A 1.5-ton air conditioner has a cooling capacity of approximately 18,000 BTU (British Thermal Units) per hour. This is based on the general rule that one ton of cooling is equivalent to 12,000 BTU. Therefore, multiplying 1.5 tons by 12,000 BTU/ton gives you the total cooling capacity.
Heating units are not measured in tons as AC units are. Heating capacity is referred to in 1000`s of btu output per hour of operation. The ratio of input vs output = the efficiency rating, for example if your home furnace is rated at 100,000 btu per hour input and 80,000 btu per hour output . it is 80% efficient (when it was new). For AC 12.000 btu = 1 ton.
48000 btu
It is 36000 BTU / 12000 (1 ton) = 3.0 ton
12,000 btu of cooling capacity.
4 Tons or 48,000 BTU
A 3-ton air conditioning unit has a BTU (British Thermal Unit) rating of approximately 36,000 BTUs per hour. This rating indicates the cooling capacity of the unit, with one ton equating to 12,000 BTUs. Therefore, a 3-ton AC unit can efficiently cool spaces that require that level of cooling power.
! ton of refrigeration is 12,000 BTU's. 1 BTU is the energy required to raise or lower 1 lb of water 1 degree F.
Cooling capacity of 30,000 btu per hour. That is the nominal total of both sensible and latent heat.
