Description:
1. Super High Air Supply Temperature in Low Temperature Environment
Scroll compressor enjoys a wider working temperature range than rotor compressor. Enhanced vapor injection can break through the limit of exhaust pressure and exhaust temperature in low temperature environment, to substantially increase the unit's heating capacity and the air supply temperature indoors.
When the ambient temperature is -25ºC, the maximum air supply temperature of EK inverter multi-connected indoor units can reach 41ºC.
2. Technology of Heating in Low Temperature Environment
With enhanced compressor frequency and the EVI function, the attenuation of heating capacity for EKRV-B series inverter multi-connected units under -15ºC ambient temperature is almost 0, which perfectly resolve the heating issue in cold areas in winters.
3. Lower Noise from Scroll Compressor
All series units adopt scroll DC inverter compressor. Compared with the common rotor inverter compressor, it features a more stable operating, less vibration, lower noise, and higher energy efficiency and longer life span.
4. Integrated Intelligent Temperature Control Technology
Quality temperature sensor can precisely detect the air supply temperature, air return temperature and indoor temperature. The indoor unit's control chip can intelligently sensor the change in temperature, and then automatically adjust the actual cooling capacity or heating capacity of the indoor unit to keep constant indoor temperature with a tiny variation of ±0.5ºC.
5. Broad Working Temperature Range
Advanced cooling system enables reliable running of EKRV-B series units. A cozy indoor environment is guaranteed, no matter in a summer when the outdoor temperature is 48ºC or in a winter when it is -30ºC.
Range of cooling operating temperature: 5~48ºC
Range of heating operating temperature: -30~29ºC
6. Exquisite Design, Pipe Connection From Three Sides
The clever design of unit enabled the refrigerant pipe to be directed out from the front side, rear side, or bottom of the unit. This is space-saving and facilitates the on-site construction.
7. Long Pipe and Large Elevation Difference

| Maximum equivalent pipe length (m) | 50 | 70 |
| Maximum elevation difference between outdoor unit and indoor unit (m) |
20 | 30 |
| Maximum elevation difference between indoor units (m) |
15 | 15 |
| Length from the first branch pipe to the farthest indoor unit (m) |
25 | 30 |
| Note: All pipe lengths here are equivalent lengths. |
8. Non-polar Communication
Advanced non-polar communication processing is adopted by connecting outdoor and indoor units with non-polar communication cables. This can prevent communication failure caused by incorrect cabling over communication ports during on-site construction.
9. Remote Monitor (Optional)
Remote intelligent control over smart phone/laptop
Intelligent software in cell phone can be used to implement remote monitor and control over air-conditioning units. Comprehensive and dynamic monitor of the running status of indoor and outdoor units make the life easier.
Centralized monitor through computer
Centralized monitor software for EK multi-connected units can perform centralized control of a maximum of 32 outdoor units.
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.
