Commercial Central VRF Air Conditioner With Brushless DC Motor

EKRV Series Digital Multi-connected Central Air Conditioner

Specifications:

Outdoor Units: EKRV040A(R)1~EKRV500A(R)1

Notes:
■  The preceding cooling capacity is measured when the indoor dry/wet bulb reads 27°C/19°C, and the outdoor dry/wet bulb reads 35°C/24°C.
■  The preceding heating capacity is measured when the indoor dry/wet bulb reads 20°C/15°C, and the outdoor dry/wet bulb reads 7°C/6°C.
■  In the preceding table, heating capacity* is only applicable to heat pump units, and is omitted for cooling-only units.
■  For details about on-site power distribution and wiring for unit installation, see the nameplate or installation manual of the unit.
■  The noise levels are measured in a semi-silent room by averaging the noise levels at four sides of the unit. The checkpoints are 1 meter away from the unit at
a height of (unit height + 1 meter)/2. In actual environment, the operation noise of the unit is generally higher due to ambient noise.

Description:

1. Higher Energy Efficiency

ide Capacity Regulation Range and Precise Ambient Temperature Control

By using a PWM valve to control the time ratio of unloading and loading status, the digital scroll compressor can continuously regulate the capacity within a range of 10%–100%, increasing the precision of capacity regulation and the stability of indoor temperature.

Low Energy Consumption

The unit boasts an outstanding IPLV(C) (refrigerating coefficient of performance). The full series of units features an IPLV(C) that is far higher than national standard energy efficiency level 1.

2. More Advanced Technologies

Rapid Start Technologies

EKRV series digital multi-connected central air conditioners can run in full load within a short period, quickly meeting indoor requirements.

Supercooling Technologies

Enlarges the condenser of the outdoor unit to implement level-1 supercooling, and then uses an efficient supercooler to implement level-2 supercooling, reaching a total supercooling degree of 19.6°C. Enhances the cooling capability of the unit and improves the efficiency of the unit. Reduces the pressure loss when the refrigerant is circulated in the pipe, rationally allocating the ultra-long accessory pipe and refrigerant.

No Electromagnetic Interference

Without a transducer, EKRV series digital multi-connected central air-conditioning units do not generate high-order harmonic and electromagnetic radiation, providing customers with healthy living and working environment.

Brushless DC motor (optional)

Fans of outdoor units can be regulated at 32 levels based on load changes, improving efficiency and reducing noise.

The unit can safely run under light load for a long time.

Intelligent Defrosting Technologies;

No Power Consumption Resulting from Power Conversion

3. Wide operation range

EKRV series digital multi-connected central air-conditioning units can generate cooling result in hot weather with a temperature of 54°C, and generate heating result in cold weather with a temperature of -15°C.

4. Ultra-long Connecting Pipe

5. Easy Installation

The system can provide an external static pressure of 50 Pa, ensuring the heat dissipation result of the outdoor unit under the same installation conditions (optional).

A higher external static pressure ensures that the outdoor unit can be flexibly installed at a rooftop, compartment, balcony, or equipment floor, preventing overload of the unit due to poor ventilation

6. More Secure

Dual Backup Operation with Guaranteed Security

Automatic Fault Diagnosis

Technologies for Automatic Identification of Pipe Length

Multiple Measures to Effectively Protect Compressors

Door Card Function (Optional)

Intelligent and Balanced Operation Management

7. electronic expansion valve

The unit uses an electronic expansion valve with 4000-step capacity regulation to increase the precision of superheat degree control (liquid level control), enhance the operation security, and improve energy saving.

8. More Intelligent

Centralized Monitoring Software

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

Separate Control Charging per Customer

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.
