MRF 7

This ensures flexible set-up for any conditions, allowing efficient operation even in the most complex projects. Thanks to its reliability and versatility, the system is easier to install and operate, which makes it a convenient solution for many facilities.

Compressor technologies

The new MRF 7-H series is equipped with a compressor featuring a technology of enhanced vapour injection (EVI) into the compression chamber that increases refrigerant circulation rate by 15% and heating capacity by 30% compared to conventional compressors. An integrated check valve further increases the system efficiency by 5%. During operation in the cooling mode, steady cooling capacity is ensured even at outdoor air temperatures up to +53 °C.

1. The compressor scroll is made of softer material, which reduces leakage and mechanical wear compared to conventional scrolls.
2. The specially shaped scroll mechanism and pressure relief valve increase stability of the system and efficiency of the compressor.
3. А reliable and efficient lubrication system with a high-pressure chamber ensures effective lubrication of all compressor parts along with low oil consumption.
4. Integrated design of the frame and casing ensures steady operation of the compressor.
5. Three-stage oil distribution system inside the compressor:
   - Gravity oil return
   - Centrifugal oil separator
   - Structural oil separator
6. The new oil pump design enables the system to operate at high speeds without additional oil consumption, improving lubrication efficiency and reducing friction losses.

Simplified equipment operation and maintenance

• Wireless connection
  Meet the world’s first MRF system with wireless communication between the indoor and outdoor units.
  Inter-unit communication routing in the system has become even more convenient.
• Deenergized valve control technology
  Even if an indoor unit becomes deenergized, the system can use communication wiring to control the EEV.
  This enables the faulty indoor unit to be safely shut down without stopping the operation of the entire MRF system.
• Reliable fan redundancy technology
  Our dual-fan system ensures reliability: if one fan fails, the other immediately activates in backup mode, ensuring uninterrupted operation of the system.

Specifications

3-phase/380...400V/50(60)Hz

Single-module: MOH7-08X2EW2AD(L), MOH7-10X2EW2AD(L), MOH7-12X2EW2AD(L)

 ^{1 Rated conditions:
Indoor temperature (cooling): 27°C DB / 19°C WB, indoor temperature (heating): 20°C DB / 14.5°C WB.
Outdoor temperature (cooling): 35°C DB / 24°C WB, outdoor temperature (heating): 7°C DB / 6°C WB.
2 The data are measured for an equivalent pipe 7.5 m long with a vertical drop of 0 m.
The noise level is measured in the third octave band, in a semi-anechoic chamber using a real-time analyser and a calibrated sound level meter.
This represents the noise level in terms of sound pressure.
3 Use a shielded wire to ensure transmission of control signals from the outdoor unit to the electronic expansion valve of the indoor unit in case the indoor unit
is deenergized. The communication cable diameter must be at least 2×1,5 mm².
The specifications may be changed by the manufacturing plant without prior notice for the purpose of product improvement.}
