Description:

?

1. 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%.

?

2. 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.

?

3. 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.

?

4. 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.

?

5. 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.

?

6. 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.

?

7. 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.

?

8. Centralized Monitoring Software

One set of EKRV centralized monitoring software can control up to 2048 indoor units, meeting customers& acute;?requirements for large-scale?centralized management.

The computer control center features a floor visualization?navigation interface to monitor the status of all units and?automatically generate alarms upon failure. It can manage user?permissions, and display and save the running records for all?units.

Schedule management: The computer control center binds the unit or cluster to the timing mode, implementing timing?settings for the unit or cluster.?Based on different requirements, the computer control center can manage each air conditioning unit in a centralized manner, including turnon/off time,?temperature setting, mode setting, and schedule setting. After schedule setting is complete, the unit automatically runs based on?the setting.

?

9. 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.

?

10. 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.

?

Applications

hotels,entertainment centers, hospitals, restaurants, office buildings, cinemas,

factories, school supermarkets and so on.

Competitive Advantage:

EKRV unit using R410A refrigerant meets the energy saving and environmental protection.

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%.
