Gree Compressor High Efficiency Vrf Units Central Air Conditioner

Product DescriptionThe vrf product has characteristic of wide operation range for low temperature cooling and low temperature heating,  high efficiency,  large air volume capacity, fast cooling, HPAC alternate Control, multiple prevention tech, SRL self-adaptive control and so on.High Performance. Energy Saving.All DC inverter compressor and high-performance pressure chamber are adopted to reduce loss of overheat and improve compression efficiency from direct intake. Compared with low pressure chamber, the compression efficiency is improved. High-efficient permasyn motor is adopted to provide better performance than traditional DC inverter compressor.DemandIn a system without external constraints, if user requires only cooling or heating, then the heat pump system is a good choice.Low CostIf there is only cooling or heating demand, a VRF heat pump system is recommended for it is cost-saving and easy to maintain.FlexibleBecause of the characteristics of the VRF system (One outdoor unit can be connected to multiple indoor units), indoor units in different areas can be controlled independently, which is very flexible in use compared to common air conditioners.I. control technologyHigh-efficiency EVI compressor, which is developed according to the features of VRF unit, its 0-420Hz adjusting range can perfectly match with the whole unit, so as to excel the performance to the greatest extent.2. Release valveImproving partial load energy efficiency, adapting to the condition of variable pressure ratio, upgrading compressor performance.3. Improved asymmetric wrapNew asymmetric wrap is adopted and compressor efficiency is improved by reducing leakage and invalid suction superheat.4. Dynamic oil balance structureAdvanced oil balance technology, with high reliability and flexible design without installation limit, which can realize parallel connection of compressors with different delivery capacity and revolving speed.5. High speed0-420Hz stepless inverter operation, wide adjustment range of capacity, precision can be up to 1 Hz.6. Oil pump filterFiltrate the impurities to ensure the supplied oil is clean.7. Positive displacement gear pumpEnsure necessary oil supply under the revolving speed, improve reliability of compressor. Product ParametersOperation Ambient TemperatureCooling -5ºC-55ºC, Heating -30ºC-27ºCRefrigerantR410aExternal Static Pressure0-300PaNoise/Db59CompressorTwo Stage EVI DC InverterPower380v/3Phase/50HzCapacity25.2kw-68kwPlace of originChinaDetailed Photos           /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
