2. General Overview
2-1 Features of the System
POWER SAVING
EHS(Eco Heating System) considers the trend in air conditioner use. It optimizes the
energy efficiency of loads ranging from partial to full. It achieves an excellent energy
effect for the users of the air conditioner.
Samsung patented compressor
Samsung has been researching and developing compressors since the 70's.
It has developed power saving compressors for more than thirty years.
The 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
compressor.
BLDC electricity
Permanent magnet, strong magnetic rotor
Double rotor compression cylinder
Nd-Fe-B Neodium-Iron-Boron magnet
SAMSUNG's double-rotor compressor has the upper and lower rotors designed symmetrically.
The double rotor in symmetry can remove vibrations caused by the eccentric design of the cylinder.
2 rotors balancing the rotary moment
Centered symmetry

High efficiency heat exchanger
EHS(Eco Heating System) uses new multiple-teeth screw pipes with a diameter of 8 mm to improve the heat exchangeability of the pipe by
30.8% .
The water-friendly aluminum foil in the heat exchanger uses the G-fin patent design to improve the efficiency of heat exchange by
13% .
DC fan electricity
The EHS(Eco Heating System) outdoor machine uses DC fan electricity. The rotational speed of electricity is 100 RPM to 1050 RPM with
step-free control. The electrical efficiency is improved by about
33% compared to AC electricity.

2-1-1 Key features of the EHS(TDM PLUS)
Quick Heating by TDM Technology
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.
Integrated Heating & Cooling system
Plate Heat exchanger is a integral part in heating & cooling system. For user’s convenience, PHE is integrated into the system.
This concept will help space saving and lower costs for pipe line reduction.
Running Costs-Reduction of Up to 33.5%
Samsung EHS, known for its world class efficiency (12kW floor heating system with 4.63), can reduce 33.5% of your running
costs as compared to a gas boiler.
Price and Space Reduction of Up to 50%
With an all-in-one outdoor unit capable of both air-to-water and air-to-air functions, Samsung EHS saves you in terms of the low ini-
tial purchase price & installation fee as well as the space needed for an extra outdoor unit.
High Performance at Low Temperature
Samsung EHS is made up of an inverter compressor optimally operated according to the outdoor temperature, offering heating
performance of 90% at -10°C and reliable frost protection at -25°C.
Heat pump operating range of DHW : -25 ~ 35 °C
At the temperature -25 °C ~ -20 °C, operation is available but capacity cannot be guaranteed.
