– R410A is a quasi-azeotrope of two refrigerants. Make sure to charge liquid one when adding refrigerant. If you charge gaseous refrigerant, it may affect the capacity and reliability of the product as a result of change formation of the refrigerant. Samsung Electronics...
– The container may get damaged by the heat and result in explosions. Do not operate the product without pressure switch(for product protection) and sensor. – If there are any internal blockage, high refrigerant pressure increase may damage the product or exterior. Samsung Electronics...
It has developed power saving compressors for more than thirty years. EHS(Eco Heating System) compressor adopts a double-rotor BLDC compressor with permanent magnets made by Samsung. Electricity for the compressor rotor is obtained from a neodium-iron-boron permanent magnetic material (boron magnet can attract iron material weighing 1000 times its own weight.) It strengthens the rotary moment of the compressor to maximize the entire efficiency of the...
Floor heating is well known as the optimal heating option for indoor thermal comfort. However, it takes 4~8 hours to heat up the room after it is turned on. Samsung EHS TDM technology quickens that process by blow- ing hot air along with floor heating to warm up the room.
