Air Conditioning Calculations - Rule Of Thumb Calculating the cooling capacity needed for your room is a complicated process as there are many factors to consider. Industrial range.- Industrial compact units, low-noise split units featuring cubic-type evaporating unit and split industrial units. wt is the theoretical weight of refrigerant. This is an important parameter for the rotation rate and transpiration heat values. Air velocity shall not exceed 100 feet per minute (FPM) any point 3 feet from the ADR system. A kilo-calorie is the amount of heat required to raise or lower 1 kg of water by 1°C. Refrigeration Calculations Pressure-enthalpy charts are tools to use in better understanding refrigeration cycles, for judging whether the operation is normal, and for estimating the effect of change in operation. 4 H2 = Sum of all heat energy added to the IC (Btu/hr). Online Books & Manuals Step 1. Goods daily rotation.- Specify the goods entry temperature and goods turnover, as a percentage of total load or as a load weight in kg, as well as the desired cooling time. Calculation of thermodynamic state variables of Tetrafluorethan - R134a in saturation state, boiling curve. NRE is the Net Refrigeration Effect per Btu per lb. q is the refrigerant circulated in lb per min. The power of the indoor unit must not exceed 25% of the total capacity; The refrigeration exchanger must be designed to prevent ice damage, and must be protected against fan breakage; Refrigeration connections must be permanent, and protected against accidental damage; … Click on each result to get a more detailed information of each issue or to modify the parameters. A watt-hour meter with scale increments of 0.1 kilowatt-hour or less shall be used to indicate the quantity of electrical energy added. Calculate tons of cooling capacity Tons = BTU/hr.
