Description:

?

Energy Efficient and High IPLV

EKRV-W series multi-connected water (ground) source heat pump units support stepless capacity modulation and deliver excellent IPLV (C) (up to 5.80) at partial load. Compared with traditional central air conditioning systems, units of this series can reduce the annual operation cost by more than 20%.

?

Large Temperate Difference, Small Flow and Less Energy Consumption

EKRV-W series multi-connected water (ground) source heat pump units feature a leading-edge digital capacity modulation design, deliver a temperature difference up to 11°C between inlet/outlet water at the water source side in summer, reduce water consumption by up to 50%, and improve energy efficiency by up to 10% compared with traditional air conditioning systems which can only deliver a temperature difference of 5°C.

?

Area-specific Design and Heat Recycle in Water System

EKRV-W series multi-connected water (ground) source heat pump units feature a leading-edge digital capacity modulation design, deliver a temperature difference up to 11°C between inlet/outlet water at the water source side in summer, reduce water consumption by up to 50%, and improve energy efficiency by up to 10% compared with traditional air conditioning systems which can only deliver a temperature difference of 5°C.

?

Stable Performance and Little Fluctuation Due to Ambient Temperature

The unit uses a stable water (ground) source as the cooling or heat source. The cooling and heating capacities vary little with ambient temperature.

Hot summer: The temperature of the cooling water is almost constant as the ambient temperature rises, and the system cancontinuously delivery high cooling efficiency.
Cold winter: The heating process involves no frosting and defrosting, and the heating efficiency is high and stable.

?

Smart and Balance Operation Management

The system automatically records the operation time of each compressor. Compressors work alternatively and automatically based on the operation time. This improves the average durability of compressors and the reliability of the system.

?

Safe Operation with Dual Standby

Compressors across modules and within the same module can take the place of one another. The whole system still works properly to meet the requirements of most rooms if some of the compressors fail to work properly.

?

Compact Compressor and Efficient Space Usage (Three Layers in Floors with Height of 3.2 m)

EKRV-W series multi-connected water (ground) source heat pump units feature compact structures. All units are 700 mm high. The volume of a 14 HP compressor is only 0.25m3. Units can be deployed in three layers if the height between floors is 3.2 m. This ensures efficient space usage.

?

Strong Dehumidification and Bacteria Dampening Capabilities

The indoor unit implements cooling through direct vaporization and delivers a strong dehumidification performance, ensuring precise indoor temperature control, excellent bacteria dampening, and an comfortable environment. The customer can choose to install a durable bacteria dampening filter to suppress mildew and maintain an excellent indoor air quality. Traditional central air conditioning systems provide cooling water with a high temperature and have indoor coils that deliver a poor dehumidification performance. The indoor humidity is high and mildew can breed easily.

?

Separate Charging

Electricity fee can be calculated in real time based on customers& acute; actual usage.
? The unit can fairly and rationally divide the electricity quantity based on the model, operation mode, operation time, air supply/return efficiency, and refrigerant flow of the air conditioning unit to protect the rights and interests of all owners.
? The unit provides customers with functions such as owner management, price and recharge management, energy saving management, and report management.

?

Models of indoor units are diverse for selection.

Indoor units cover 6 series and 63 capacity types, and total fresh air indoor units are available, fully meeting customer requirements.
