Aluminum fin: double stamping flanging technology and double corrugated fin design are adopted, and the mechanical tube expansion process is adopted to ensure the close combination of aluminum fin and copper tube, so as to obtain the best heat exchange efficiency. Each cooling circuit corresponds to a coil condenser, and multi circuit units can be used as standby for each other to improve the reliability of the unit.
4.Evaporator
The direct expansion evaporator and copper tube are seamless copper tubes with high heat conduction, covered with high-purity aluminum sheet. The aluminum fins is only attached to the copper tube and mechanically expanded, so that the copper tube and aluminum sheet are closely bonded.
5. Advanced control system, complete protections
The well-known brand microcomputer controller , which has perfect automatic control function and can realize remote control. The heat pump type unit automatically defrost, and the unit has multiple protection and regulation configurations, which is safe and reliable. The new cooling system is adopted to make the unit cooling or heating at outdoor low temperature. The ambient temperature of the heat pump system is 0 ~ 45 ℃ for cooling - 10 ~ 20 ℃ for heating. The unit is equipped with high pressure, low pressure, overload, short circuit, open phase, overheating and air flow pressure difference protection.
6.Beautiful appearance
Advanced electrostatic spraying coating technology, smooth and beautiful appearance, with high anti-corrosion performance,suitable for long term operation in outdoor .
