General requirements
Refrigerant (Gas): R134a Speed range: 1000～2300 rpm / 1000～3300 rpm Working pressure: Suction pressure: 0.2～0.45Mpa Discharge pressure: ≤2.0Mpa / ≤2.2Mpa pressure ratio: ≤10 Ambient temperature: -40℃ - 80℃ Discharge temperature: ≤110℃ Lubricating oil require: 8%-10% of whole system refrigerant (Gas)
Compressor data:
Compressor style: Semi-closed Horizontal Scroll Compressor Material: Aluminum alloy Voltage: DC 12V / 24V Working voltage range: 10.5VDC～15VDC / 19.5VDC～32VDC Current: 45A+-2 / 35A+-2 Displacement: 21cm³/r Cooling capacity: 1.688KW / 2.465KW (5731BTU / 8410BTU) Speed range: 1000 - 2300rpm / 1000 - 3000rpm Rated power: 550W / 850w Rated speed: 1800rpm / 3000rpm Oil: POE / 130ml - 150ml (Oil has already in compressor ) Gas/Refrigerant: R134a Condensing temperature range: 26.7～68℃ Evaporating temperature range: -10～12.5℃ Refrigerant leakage rate: <14g per year Suction pipe inner size: Ø18.3mm Discharge pipe inner size: Ø15.5mm COP W/W: 3.07 / 2.9
Compressor body not to be tilted (the angle between the main axis of the compressor and the horizon should not be greater than 5 °)
Brushless controller unit：
Brushless direct current controller 1. Over / Under voltage protection: DC 12V -- ( 21V / 10.5V ) DC 24V -- ( 42V / 20.5V ) 2. Max power: 600w / 1200W
Generator (battery) request：
12V compressor require generator ampere over 100a; 24V compressor require generator ampere over 70A. About vehicle battery. If you want to use the electric compressor after parking, then your vehicle battery capacity should be large enough. For example, 12V compressor current about 45A. So one new and full charged 45A battery can run the compressor for one hour.
Led blinking:
Blinking 1 times, pause 1 second: Standby mode. Fast blinking 2 times, pause 1 second: Excessive current, Over 50A. Fast blinking 3 times, pause 1 second: Locked rotor protection. Fast blinking 4 times, pause 1 second: Undervoltage protection. Fast blinking 6 times, pause 1 second: Electric fan fault. Fast blinking 7 times, pause 1 second: Motor lack of phase. Please check if the motor got burnt and connection is correct or not. Fast blinking 8 times, pause 1 second: Compressor over heated protection. Fast blinking 9 times, pause 1 second: Pressure switch protection.
