What is a heat pump
Benefits of a heat pump
The Samsung EHS includes a range of advanced functions that help optimize energy usage and are independently certified as delivering enhanced energy efficiency as compared to the previous models. The 2-Zone Control enables simultaneous heating with two different water temperature demands. The Photovoltaic Enabled feature checks the status of solar panels and adjusts the temperature to reduce network electricity usage. While the Smart Grid Ready feature helps users take advantage of economically efficient and sustainable power supply options.
The Samsung EHS outdoor unit’s Durafin™ Ultra has an anticorrosive layer of epoxy acrylic and a hydrophilic layer of acrylic resin that disperses water and reinforces its corrosion-resistance. Its improved quality was proven using the Salt Spray Test (SST) over a period of 2,280 hours¹ with no leakage of refrigerant².
The enhanced energy efficiency helps save costs on heating bills. The Samsung EHS has a Seasonal Coefficient of Performance (SCOP) A+++³ energy efficiency rating, therefore they are proven to operate with a high level of efficiency. EHS Mono and Split achieve a good heating performance at low temperatures by using R32 refrigerant. The R32 refrigerant has a high PdesignH (kW), and works reliably and efficiently even in a cold climate.
Unlike conventional fixed-speed compressors, which frequently shut off and switch on, the compressor automatically adjusts its speed in response to changes in the surrounding room temperature. So it helps to ensure optimum comfort by maintaining the desired temperature with little fluctuation. And it optimizes power usage which reduces energy consumption.
The smart compressor design and premium moving parts of the Samsung Eco Heating System deliver a balanced performance, fully complying with EU regulations for enhanced efficiency⁴. The Twin Rotary BLDC Compressor of the EHS outdoor unit offers you greater efficiency and reliability. Its twin cams and two balance weights create low levels of vibration, contributing to a smoother and quieter all-around performance. The use of high-quality moving parts, such as robust bearings and premium matching rollers and vanes, also ensures much better stability and durability.
The Samsung EHS Mono and Split are designed to deliver both sophisticated heating capabilities and green living credentials demanded by modern households*. * https://www.samsung.com/semiconductor/about-us/green-management/
The EHS Split 4-way piping system⁵ has pipe access possibilities at the front, side, bottom and rear, so it provides much more flexibility during installations. It can be configured to suit almost any installation location without additional fittings, while still being discretely concealed.
The combination of superior insulation and low vibration generates less noise, so it creates a comfortable atmosphere. Due to Samsung’s newly developed Sine Wave Controller technology you can hear much less noise when the air conditioner is running as compared to previous versions. Unlike a conventional Square Wave Controller, which emits a noticeable sound, it produces current waves that have a smooth curve with no spikes or ripples. This significantly reduces the noise created by the outdoor unit, so it operates very quietly⁶ and creates less disturbance.
The compressor is fully covered in double-layered sound insulation material that absorbs and minimizes noise. When it is applied, the sound becomes about 3 dB(A) quieter⁷. So it operates quietly and discretely, while still delivering high-quality performance.
The Samsung EHS unit which provides the indoors with heating energy is installed outdoors to extract heat from the ambient air. Therefore, whenever the compressor operation is stopped during ambient conditions below 0 ℃, the water inside the pipes may freeze and expand, this can damage the water pipes and the components. In order to prevent this, the Anti-Freeze Protection control function activated by default. In non-operation mode, if the outside temperature drops to 3 ℃ or below, the pump on the water pipe side is forcibly operated to prevent freezing in the water pipe. For external water pipes and Anti-Freeze protection feature use propylene glycol with a toxicity rating of Class 1 as listed in Clinical Toxicology of Commercial Products, 5th Edition⁸.
¹ Based on testing by a third-party lab in accordance with ASTM B117, an official test method. For more details, please contact Samsung’s technical professionals. ² Based on testing by a third-party lab, applying the actual pressure of refrigerant for 1 minute, after a Salt Spray Test (SST) of over 2,280 hours. ³ Air-to-Water Condition : (Heating) Water In/Out 30 ℃/35 ℃, Outdoor Air 7 ℃[DB]/6 ℃[WB]; (Cooling) Water In/Out 23 ℃/18 ℃, Outdoor Air 35 ℃[DB]. ⁴ All Samsung EHS products comply to EU EcoDesign's Minimum Energy Performance Standards (MEPS). ⁵ Only available on certain models. Contact your local Samsung representative for complete product information. ⁶ Based on Samsung’s internal test results compared with the Samsung AR09FSSKABENEU model. Individual results may vary. ⁷ When testing Split 6 kW and 9 kW models based on internal testing in Samsung Korea. Results may vary depending on environmental factors and individual use. ⁸ Please refer to the installation manual for detailed anti-freeze specifications. Anti-Freeze Protection control should be used only for auxiliary measure in addition to glycol mixture.
