C.Series brief introduction
1.High energy efficient
Domestic Air Conditioner
Model:
HSU-24H03/Z HSU-24C03/Z
The design of inner-grooved copper tube greatly increases the refrigerant contact area and the
efficiency of cooling/heating functions.Using the R410A refrigerant and the refrigerating system optimizing design make both the EER and COP reach the B class according to the european energy efficient standard.
2.Comfortable:wide-angle airflow The vertical dual-flap and horizontal wide-angle louvers ensure the cool/warm air reaches every corner of the room.
3.Health air purifying An air purifying filter with deodorizing and disinfecting functions keeps the air clean and users healthy.
4.Quiet operation Fan with random-pitched blades. Random-pitched blades help reduce operating noise while maintaining a high airflow rate.
5.Convenience Auto restart and washable panel: The grille can be removed easily and washed when necessary.Any series have the function then even if the power falls when the unit is operating unit will automatically return to the operating settings in use before the power failure when power is restored.
6.Wide variety of functions 24-Hour Timer: 24-hour timer allows users to select the exact time they would like the air conditioner to turn on and to turn off.Timers on previous models operation based on the number of hours of desired operation.
7.Night-set models When the air conditioner is operating on the timer-off circuit.The preset room temperature gradually rises(going down in heating)before the unit stops as shown
below.Users can sleep
comfortably without sudden change in temperature.
8.Program”dry” This function automatically reduces the level of humidity while maintaining the preset indoor
temperature.
