The process requires a methodical approach that considers not only the cooling load but also system integration, refrigerant properties, application requirements, and energy efficiency goals. Cold W. A general calculation is 60 Btu/hour/ft 2 of window. 5% accuracy). Measure the flow of water through your 1 RT = 12000 BTU/hr. To determine the tonnage needed for a specific space, divide the total BTUs by 12,000. It is the product of the refrigerant circulated and the net refrigeration effect. This calculator allows you to quickly find the BTU per kWh, which starts by showing 1 kw to BTU is 1 kW = 3,412 BTU/hour We would like to show you a description here but the site won’t allow us. Lastly, the required AC power measured in kilowatts (KW) is also crucial for efficient energy use. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load BTU Calculator. Enter data, including your walk-in cooler or freezer dimensions, temperatures, and performance factors, into the appropriate fields. com 1 Ton of Refrigeration = 12,000 Btu/h = 3. BTU stands for British thermal unit, which is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. The British Thermal Unit (BTU) is the basic measure of heat energy in the Imperial system. The relative humidity of the air is 70% at the start and 100% at the end of the cooling process. Further on, we also solve examples for 9000 BTU, 18000 BTU, and 24000 BTU. The Btu (IT)/hour [Btu/h] to ton (refrigeration) conversion table and conversion steps are also listed. One BTU is defined as the amount of heat necessary to raise of water 1F. It was first proposed in 1882 by William Siemens who defined it as "the power conveyed by a current of an Ampere Here’s how BTUs affect the overall performance of your air conditioner: 1. It’s usually measured in British Thermal Units (BTU) per hour or in kilowatts (kW). The heat required to melt 1 lb of ice at 32 o F to water is 144 Btu. Use the dropdowns below to help you estimate what size air conditioner is best for your space. Although, at Kobie Complete, we factor in many details to determine the exact BTU your new air conditioner should have, our free online BTU and Tonnage Calculator will give you a rough estimate.

Temperature units: Default is Celsius, Switch to Fahrenheit using tiny switch button at top of each calculator page. If the walls of the refrigerated space are exposed to the sun, additional heat will be added to the heat load. From the Mollier diagram we estimate the water content in the hot air to be 0. How to estimate cooling capacity: For example, if you have a room area of 500 ft² with average insulation, 3 windows, and 2 occupants: Base load = 500 ft² × 20 BTU/hr = 10,000 BTU/hr This calculator helps you convert cooling tonnage between Tons of Refrigeration (TR), kilowatts (kW), British Thermal Units (BTU) and Thousands of BTUs per hour (TMBH). Accumulators Rec Muffler ETC; Expansion Valves; Filters-Driers; Ice Machine Parts (OEM Only) Misc. Then, multiply the square footage by 25-50 btu/hr. On the other hand, one BTU per hour is equal to 8. Consult our technical advisors for precise calculations. ) of ice in 24 hours. On top of that, you will also find a chart for mini split sizes for 300 to 5,000 sq ft Watt. The Sizing Calculators provided by ICEqube, Inc. Understanding refrigeration capacity is crucial for several reasons: While our basic calculator above is a good guideline, be sure to perform an in-depth heat load calculation and do not size purely on cubic feet. In general, the calculation of 100 BTU for each square feet of the room is used.

However, using our BTU heat calculator and BTU converter is These measurement units are Btu and ton of refrigeration. BTU to kW calculator. Kitchens normally have more heat thanks to stoves and ovens, and rooms with computers and 80,000 Btu actual output; If the same 100,000 Btu furnace has an efficiency rating of 93% it will produce: 100,000 Btu input; X . Step 2 Choose the option that best describes your enclosure: Very Loose. 0075 kg water/kg dry air . I know the volume: ft 3. We can see that we would need about 10,600 BTU to adequately cool this 400 sq ft room. 2. To help you out with this conversion (BTU/hr to tons of refrigeration, to be exact), we have prepared a simple-to-use BTU to ton calculator. BTUs represent the amount of heat that needs to be removed from the space. 6 in) Legend: “Q Total” is total heat transfer in BTU per a) Specific hour 8 (BTUH) “U” is coefficient 8 of 1 Btu = 0. We can calculate the BTUs per hour from the given HP using this formula: BTU/hr In HVAC, the BTU to tons conversion is frequently used. For this example, the cooling tower has a water flow rate of 200 gallons per minute. We do not recommend you rely only on these results while going to purchase an air conditioner. In between the two units are two sets of refrigerant piping. Just fill in your home’s square footage, the number Btu per hour can be abbreviated as Btu/h; for example, 1 btu per hour can be written as 1 Btu/h. Pick the type of calculation you need and wait for the page to load. Coolselector®2 helps you optimize energy consumption and increase efficiency in any HVACR system. h = heat of compression (Btu/lb) h lc = enthalpy of vapor leaving Calculating chiller and cooling tower refrigeration loads - in tons. If your AC has too few BTUs for the room size, it will struggle to cool the space effectively. Nov. The beef enters the freezer pre chilled at 4°c and the required Calculate Net Refrigeration Effect (NRE): Btu/lb Capacity. Also, explore tools to convert Btu (IT)/hour or ton (refrigeration) to other power units or learn more about power conversions. When we specify or measure an air conditioner’s output in BTU/H, we can calculate the EER (energy efficiency ratio) by dividing BTU/H output by KW input at a given operating point. R. You need accuracy to ensure your heating, ventilation, and air conditioning (HVAC) systems work properly in your home or office. There also industry specific rules of thumb for chiller sizing depending on your application. To convert British Thermal Units (BTU) to tons of refrigeration, you can use a simple conversion formula.
