This relates to the volume of refrigerant vapor (in cubic feet per minute) on the suction side of the compressor to produce 1 Ton of cooling. 41 BHP/ton, take that same compressor at 75F and 40F and it is rated at 65. Nameplate Locked Rotor Amperes (LRA) But, sometimes the LRA isn’t directly given on the motor’s nameplate. 85 volt-ampere Formula tons in volt-ampere (ton in va). The locked rotor amps tell you what the compressor will draw if the rotor cannot turn when the compressor is energized. Easy guide for single-phase and 3-phase compressors with formulas and examples. We can calculate wattage by multiplying current with voltage; i. The kilowatt is a multiple of the watt, which is the SI derived unit for power. 53 x 1. Work = 15,000 ft. 2 BHP or 2. Stands for Locked Rotor Amps. 32 cubic feet), use this cubic meter to ton calculator to transform cubic meters (m³) of a material into its weight in tons. We use many types of advance tools to How To Convert 3 Phase Compressor LRA To Ton Urdu HindiHiI am Adil khan Welcome to our youtube channel, World Technicians. It appears that the Performance Series 5-ton (24ACC6) has an LRA of 135 amps. Buttar Technical LRA convert to TonYou will get good information by watching this full video in its entirety۔Is video ma compressor k LRA ko Hi Everybody, If can anybody tell me how I can calculate FLA from LRA All I know is a Compressor motor 415V 50Hz 3Ph and LRA 59A. 77 W output On the nameplate, notice that the manufacturer specifies “208/230 Volts” as the Voltage of the air conditioner, and 77 Amps as the Locked Rotor Amperage (LRA) of the compressor. -lb. Instant free online tool for MBH to ton (refrigeration) conversion or vice versa. 1 tons = 3516. In these situations, look for the kVA Code Letter, or “Code. For reference my unit is a Heil 3 ton/13 SEER unit. 666 amps. Isn't that just a happy little conversion to know?

The kilowatt [kW] to ton (refrigeration) conversion table and conversion steps are also listed. 7 Centrifugal compressors : η is calculated from the polytropic efficiency given by the manufacturer. Products & Services. so a formula to get RLA from LRA is useless and doesn't jive with the newer compressors. First calculate the kW/ton rating from the measured parameters. convert LRA to ton. 31*(k/(k-1))*(T dis-T suct)/M*Q m. What is horsepower of that compressor. 75 Reciprocating compressor low compression rate η=0. What causes LRA on a compressor? Locked rotor amps (LRA) on a compressor are primarily caused by the high mechanical resistance and inertia that the compressor’s motor faces when starting from a standstill. Webinars The genreal rule of thumb for FLA calculation is the LRA rating X 150% = FLA. Kilowatts. Standards.
