3160 Line Current (1 Phase) Amps = KW x 1000. 41,000 Btu/h. Internal heat from … Step 2: • Calculate the maximum appliance input. 3 kW water heater . This is the total heat loss at the outdoor design temp and the minimum output needed from the new furnace. Convection: ̇= ℎ(. − ∞) Radiation: ̇= (. 4 −. The parameters involved in its calculation are shown below (from Steadman, 1979). Iron Sheath.S.) 5,000 Btu/h difference Location of the House. ft. 14 kW range . Volts Line Current (3 Phase) Amps = KW x 1000. The total cooling or heating load of a building consists of two parts, the sensible heat, Qs , and the latent heat, Ql . 36,000 Btu/h. Put your presentation title or confidentiality info here. (Per 9.3.1.1, Exception 2, dryers are not included.) of ice at 32°F 288,000 BTU/24 hr. SUB TOTAL HEAT LOSS 43,567 BTUh Heat Loss Factor Scaler Multiplier .10 x 1.74 = .17 x 43,567 = 7,406 BTUh 7. To calculate wattage, use formula A for the heat needed to rise from initial to the point of change. 3.412 x Heat-up Time (Hours) Formula C : *** The Specific Heat of a material changes at some temperature due to melting (fusion) or evaporation (vaporation). Water heater Space heater Range Other Total Total/1000 Step 2: • Calculate the total input of all appliances in the room. Conduction: ̇= −. Each of these parameters can be described by an equation but they are given assumed magnitudes (in parentheses) in order to ... \WINDOWS\Desktop\heatindx.PDF • Enter the input rating of all appliances in Table 1. HVAC FORMULAS TON OF REFRIGERATION - The amount of heat required to melt a ton (2000 lbs.) • Divide the total by 1000 (of Btu/hr). The sensible heat load comes from the following sources: 1. 5 kW clothes dryer . 2. Worst Case = North West. Volts x 1.73 Applied vs. 4) Heat transfer for an internally reversible process: . . = ∫ . Figure 54. Heat conducted through the building (walls, ceiling, floor, windows). 2800 sq. Heat Transfer and Work Relationships . Heat rejection as a function of the mass flow rate of air, radiator borrowed from formula team..... 71 Figure 55. Single Family Dwelling Load Calculation – Step by Step Example (Optional Method) CEC 220.82. • Total the column. Rise. Add Sub Total and Duct Loss to arrive at J: Total BTU/H Loss-Entire House. calculation due to changing solar heat gains at various times of the day. Then calculate using formula A with the new specific heat from the point of change to the Allowable Watt Density & Heater Selection - Air Heating Graph G-105S — Strip Heater Air Heating-Selection of Watt Density Graph G-106S — Finstrip® Heater Air Heating-Selection of Watt Density W/In 2 20 15 10 5 0 ABC Outlet Air Temperature (°F) 700 600 500 400 300 200 100 0 16 9 4 1 16 4 1.S.) Calculations for heating air in a duct Once the volume of air in standard cubic feet per minute (SCFM) and the required temperature rise in °F (ΔT) are known, the required kilowatt rating (KW) of the heater can be determined from the following formula: Basic Air Conditioning Formulas TO DETERMINE COOLING Total Airflow Infiltration or Ventilation Number of Air Changes Per Hour – Total Number of Air Changes Per Hour – Outdoor Air Total Heat (HT) Sensible Heat (H S) Latent Heat (HL) Leaving Air D.B. Location of the House. Heat rejection as a function of the mass flow rate of … APPROXIMATELY 2 inches in Hg. (mercury) = 1 psi WORK = Force (energy exerted) X Distance 12,000 BTU/hr. . Rated KW Factors Rated Voltage Applied Voltage; 120 208 220 230 240 277 440 460 480; 120: 1.00: 3.00: 3.36: 3.67: 4.00: 5.33: Temperature (T2) Enthalpy – Leaving Air (h 2) Leaving Air W.B. Heating and Air-Conditioning (The Largest of the following shall be included): 1. Electric Heater Formulas Conversion 1 KW = 3413 BTU Load Requirement KW = CFM x Temp. 1.5 kW dishwasher . Design Considerations: Best Case = East. The Heat Index (or apparent temperature) is the result of extensive biometeorological studies.
