Specifications

Note:
■ Air conditioning mode: Test conditions for nominal cooling capacity: outlet water temperature 7°C; water flow: 0.172 m3/(h·kW);
outdoor ambient temperature 35°C. Test conditions for nominal heating capacity: outlet water temperature: 45°C; water flow: 0.172m3/(h·kW);
temperature of outdoor dry/wet bulb: 7°C/6°C.
■ Cooling + Heat recovery mode Test conditions for nominal cooling capacity: Hot water side: Outlet water temp. 45°C; nominal water flow for hot water mode.
Air conditioning side: Outlet water temp. 7°C; nominal water flow for heating mode.
■ Hot water mode: Test conditions for nominal water flow: temperature of outdoor dry/wet bulb: 20/15°C; Temperature of inlet/outlet water: 50/55°C.
■ Water resistance at the air conditioner side includes water pressure drop of the unit and the attached Y-shaped filter.
■ Water resistance at the hot water side includes water pressure drop of the unit and does not include the pressure drop at the Y-shaped filter and other components.
■ Pipes outside the unit need to be customized and installed on site. The diameter of the pipes must meet design requirements. EK does not provide the pipes.
■ Full heat recovery units and other units can be combined to form partial heat recovery modular system. Full heat recovery units can also be combined to form a
total heat recovery system. Modular units can be formed using the 1~16 basic modules. The above table lists the parameters for common module combinations.

Efficient Components and Optimized System Design

The EKAC series low-temperature high efficiency total heatrecovery modular air-cooled heat pump unit features stateof-the-art enhanced vapor injection (EVI) technologies, increasing refrigerant recycle by 20%. The evaporation capacity is improved by mid-pressure refrigerant intake. One compressor compresses refrigerant 2 times in each cycle.Half-M fins are used to improve the heat-exchange efficiency
of the heat exchanger. The unit features state-of-the-art cross diagonal convection angles for stainless steel braze-welded panel-type heat exchanger and stainless steel braze-welded panel-type economizer (used to increase the enthalpydifferentiation between the inlet and outlet of the evaporator). An EXV is used to precisely control the operation of the unit. Leading-edge Technology and Stronger

Cooling and Heating Capacities

The EKAC low-temperature high-efficiency modular aircooled heat pump unit features excellent heating COP
when the ambient temperature is low (20% higher than common air-cooled heat pump unit when the ambient
temperature is -10°C).The lower ambient temperature limit is expanded from -10°C of common units to -20°C. This greatly improves cooling performance in areas where the winter is cold, reducing or eliminating the need for auxiliary heaters.

Efficient and Energy Saving

Each modular unit has two power gears. When multiple modular units are combined, there could be many power gears. When working at a partial workload (99% of the operation time), the unit intelligently regulates the output based on the actual workload, making the operation efficiency even higher. With an optional 2-way valve water control feature, the unit can send out signals to cut off chilled water. This enables automatic flow control for pumps in line with the transducer, which helps save more energy.

Operation in Low Temperature Areas

The EKAC series low-temperature high-efficiency total heatrecovery unit features state-of-the-art EVI enthalpy increase technologies, and can provide effective heating and sufficient hot water when the ambient temperature is as low as -20°C. The unit can provide effective heating for areas that are extremely code in winter.

Safe and Comfortable

fast heating; hot water available as soon as you turn on the tap; absolutely safe as there is no emission of
harmful gas and the risk of electric shock is eliminated by separating water and electricity. The central hot water system can provide hot water with a stable temperature for multiple outlets, making bathing comfortable.

Lower Investment

Investments can be made in installments as the project rolls out. This reduces initial investment for new projects and making renovation project easy to complete.

Hybrid Connection Technology

Units of this series support modular connection with common air-cooled heat pump units to meet various
heat recovery requirements.

Smart Control

Units of this series are controlled by microcomputers. Each control module can control up to 16 units, making
unit combination easier. Temperature and level of water in the water tank are controlled automatically, and the
water pump starts/stops automatically. No dedicated operator is required, reducing the management cost by
easy smart control.
