The Samsung EHS TDM Plus AE066MXTPEH/EU outdoor unit is a single-phase air source heat pump designed for systems capable of combining air-to-water and air-to-air climate control. It offers a rated capacity of 6.6 kW in heating and 6.7 kW in cooling, making it possible to deliver a complete solution for heating, cooling and, together with the appropriate indoor components, domestic hot water production.
Samsung TDM Plus technology makes it possible to use a single outdoor unit to supply both the EHS system hydraulic circuit and compatible direct expansion indoor units. In this way, depending on the project configuration, underfloor heating, fan coils or other hydraulic emitters can be combined with air-conditioning indoor units.
The main feature of the TDM Plus range is its ability to integrate two forms of climate control within a single solution. The air-to-water system can supply thermal energy to the heating or cooling hydraulic circuit, while the air-to-air system allows rooms to be conditioned directly through compatible indoor units.
Samsung highlights that this architecture makes it possible to quickly reach a comfortable temperature through air conditioning and complement operation with hydraulic systems such as underfloor heating. All of this is managed through the compatible controls of the TDM Plus system.
The Samsung AE066MXTPEH/EU provides a rated heating capacity of 6.6 kW. Under Samsung's specified rated conditions, it achieves a COP of 4.49, with a rated electrical consumption of 1.47 kW.
The actual performance of a heat pump depends on factors such as outdoor temperature, water supply temperature, building demand, the emitter system and the overall installation configuration.
In cooling mode, the outdoor unit offers a rated capacity of 6.7 kW and an EER of 4.53 under the test conditions indicated by Samsung. The declared rated electrical consumption for cooling is 1.48 kW.
Cooling can be used through the hydraulic circuit with compatible emitters or through direct expansion indoor units, depending on the installed TDM Plus configuration.
The Samsung EHS TDM Plus AE066MXTPEH/EU is designed to operate in heating mode at very low outdoor temperatures. Samsung specifies the following operating ranges:
These wide ranges allow the system to be used throughout the year, always within the design and operating conditions established by Samsung.
The Samsung EHS range is designed to harness the energy contained in the outdoor air and transfer it to the climate control system using heat pump technology.
Samsung's energy documentation places this combination in class A++ for low-temperature heating applications and class A+ for medium-temperature applications, depending on the evaluated system configuration.
Low-temperature emission systems, such as underfloor heating, are especially suitable for taking advantage of the performance of an air source heat pump.
The AE066MXTPEH/EU reference corresponds to an outdoor unit with single-phase power supply. Samsung specifies a rated current of 6.9 A in cooling and 6.7 A in heating.
The cable size, electrical protection devices and the rest of the installation components must be sized according to Samsung's manual, the line length and the applicable electrical regulations.
The outdoor unit uses R410A refrigerant and has a factory charge of 2.6 kg. Samsung states an equivalent of 5.43 tCO2e for this charge.
Any additional charge that may be required will depend on the design and length of the refrigerant piping. Any intervention on the refrigerant circuit must be carried out by qualified personnel and in accordance with applicable regulations.
The Samsung AE066MXTPEH/EU uses the following refrigerant connections:
Maximum lengths, height differences, additional charge and other installation conditions must be checked in the technical documentation corresponding to the specific EHS TDM Plus system configuration.
The outdoor unit incorporates a rotary compressor that works together with the heat pump's electronic control system.
The control system adapts operation to the thermal demand of the system, helping maintain stable climate conditions and optimize performance compared with conventional fixed-speed systems.
The propeller-type outdoor fan provides an air flow rate of 47 m³/min, allowing the necessary heat exchange between the refrigerant circuit and the outdoor air.
To ensure proper operation, the minimum installation distances recommended by Samsung must be respected and the air inlet and outlet areas must be kept free of obstacles.
Samsung specifies a sound pressure level of 47 dB(A) in cooling and 48 dB(A) in heating. The declared sound power level is 67 dB(A).
The perceived noise in the installation will depend on factors such as the location of the outdoor unit, the distance, the presence of walls or other reflective surfaces and the operating conditions.
The TDM Plus concept allows a single outdoor unit to take part in both hydraulic climate control and direct air-based climate control. This helps reduce the outdoor space occupied by equipment and makes it possible to develop flexible installations adapted to different rooms and thermal needs.
In a complete configuration, it can be combined with hydraulic modules, ClimateHub and compatible Samsung indoor units, according to the combination tables and limits established by the manufacturer.
With dimensions of 880 x 793 x 310 mm and a net weight of 61 kg, the Samsung AE066MXTPEH/EU offers a relatively compact solution for a system capable of integrating air-to-water and air-to-air applications.
Its capacity of 6.6 kW in heating and 6.7 kW in cooling, together with a rated COP of 4.49, heating operation down to -25 °C and the versatility of the TDM Plus system, make it a particularly suitable option for residential projects looking to centralize different climate control needs through air source heat pump technology.
Important: this reference corresponds exclusively to the Samsung EHS TDM Plus outdoor unit. To have an operational system, it must be combined with the indoor units, hydraulic module or ClimateHub, controls and compatible accessories required by each installation. Final performance and efficiency depend on the complete selected combination.
