Products Description
Product introduction
MRAC-A Plus Standard Series Modular Air Cooled Chiller (Heat Pump) absorbs the essence of industry technology, listens to the application experience of product owners, and meets the user's requirements for product efficiency, safety, intelligence, comfort and affordability to the greatest extent.It can be widely used in new and reconstructed large and small industrial and civil buildings, such as hotels, entertainment centers, hospitals, restaurants, MRAC-A Plus Standard Series Modular Air Cooled Chiller (Heat Pump) office buildings, cinemas, factories, supermarkets and other places, especially suitable for noise and surrounding environment with high requirements, lack of water and not suitable for installation of cooling towers.The modular unit has flexible installation, can be invested in phases, and has a short construction period, no cooling water system, simple pipelines, moderate investment, and has become one of the preferred forms of air conditioning system for many users.
Product advantages
Energy Conservation And Emission Reduction MRAC series adopts the efficient and environmentally friendly R410A refrigerant and its ODP is 0, which means the products will not destroy the atmospheric ozone layer. A maximum cooling capacity of unit volume that requires a much smaller refrigerant charge compared to traditional refrigerants could help reduce greenhouse gas emissions. Energy Efficiency Ratio The MRAC air conditioning unit is innovative and features a leading air-cooled heat pump design concept. It has a full load energy efficiency ratio that exceeds the national energy-saving product certification standard (COP3.2 or above). Each unit module of the unit has secondary energy regulation. When combined with other modules, it provides multi-level energy regulation. The system selection and matching are fully optimized to ensure that the unit is always in the most energy-efficient state, resulting in higher energy efficiency for some loads (approximately 99% of the total operating time of the air conditioning) and a 4% increase in overall efficiency. Strong Environmental Adaptability Steel plate: Adopting environmentally friendly galvanized steel plates certified by the European Union's "ROHS" certification, the body has the characteristics of anti-corrosion, rust prevention, and non fading, making it durable and durable. Operating range: The unit has undergone strict long-term testing according to national standards, and can operate normally whether it is cooled in hot weather at 48 ℃ or heated in severe cold weather at -15 ℃. Lower half enclosed structure: The lower half of the unit adopts a sheet metal fully enclosed structure, effectively protecting the main components inside the unit, improving long-term heat exchange performance, and extending the service life of the entire unit.
Efficient Heat Exchanger
Efficient Heat Exchanger The dual-system vacuum brazed plate heat exchanger is made of stainless steel. It adopts the dual-system diagonal-flow design to substantially increase the effective heat exchange area, and boasts higher heat exchange efficiency than shell-and-tube heat exchangers. The dual-system design can automatically adjust the heat balance to guarantee high efficiency and reduce the risk of freezing. The water-side 1.6 Mpa pressure bearing can adapt to the requirements for water systems in ultra-high buildings. The standard water differential pressure switch monitors the unit water flow in real time and provides precise anti-freezing control. Accurate Adjustment, Energy-saving Operation Intelligent Defrosting Technology Compared to traditional air-cooled module units that use thermal expansion valves for regulation, MRAC air-cooled modular units use imported 500 level PMV electronic pulse precise regulation to achieve PID precise control of the electronic expansion valve. This results in real-time system control. Dynamic matching improves the accuracy of water temperature control, enhancing the efficiency of each component in the system. This allows the unit to operate stably at any load and adapt automatically to changing environmental conditions. Thoroughly solve the oscillation problem of the refrigeration system to achieve more stable temperature output and uniform indoor temperature, improving human comfort.
Intelligent Defrosting Technology
Adopt “AI adaptive” intelligent defrost technology, multi-dimensional data analysis, through the collection of pressure sensor data, temperature sensor data, system load output status, unit operating time, -superheat and other data combined with the last defrost data with the heat exchanger and heat exchanger flow paths, from a multi-dimensional judgement of the system defrosting situation, accurately grasp -Entering the defrosting timing, the high degree of certainty about the defrosting state and the amount of defrosting reduces the defrosting frequency and defrosting time of the unit, ensuring that the comfort of the indoor environment is not affected. Modular staggered defrosting technology: a single unit can achieve intelligent staggered defrosting, when a system defrosts, another system normal heating, defrosting unit does not shut down, to ensure stable operation of heating, to ensure that the user's normal heating needs. Modular staggered defrost technology: a single unit can only achieve staggered defrost, when a system defrost, another system of normal heating, defrost unit does not stop, to ensure stable operation of heating to ensure that the user's normal heating needs. Low Noise The entire unit is designed with vibration isolation and multiple noise reduction treatments. It adopts a low-noise brand fully enclosed scroll compressor and a low noise fan, making the noise and vibration of the unit reach industry-leading levels; Through noise spectrum analysis, strict comparison, selection, and improvement were carried out on components such as fan motor, and professional noise reduction treatment was carried out on structures and pipelines. Lower half enclosed structure: The external part is enclosed with sheet metal, effectively shielding the external transmission of compressor noise. Fan: the optimized combination of efficient fan silent blades and efficient customized motor can achieve perfect performance. The motor is directly connected and the blades have passed strict dynamic and static balance tests;
Safe And Reliable
MRAC-A Plus Standard Series Modular Air Cooled Chiller (Heat Pump) have undergone long-term laboratory verification tests, including a series of tests on corrosion resistance, fatigue, and frequent starting and stopping under extreme conditions, which make the units have extremely high reliability. Each unit passes 100% online test before leaving the factory, the standard configuration of the unit with water filter and water pressure difference switch leaving the factory, so that the unit will not operate under water shortage or flow breakage, and the operation of the unit is reliably guaranteed. Powerful Protection Features Built-in multiple protection functions: compressor high and low voltage protection, compressor operation out of step protection, IPM module protection, VDC over undervoltage protection, input power supply abnormality protection, frequent start-up protection, compressor overcurrent protection, compressor exhaust temperature protection, unit anti-overheating protection, sensor failure protection, refrigeration anti-freezing protection, winter water system anti-freezing protection, insufficient water flow protection, ambient temperature protection. When any fault occurs, the controller automatically realises real-time alarm.
High compatibility
Master/slave integration: Any slave module can be used interchangeably as a master module. A damaged master module will not affect the use of other modules. Modules of the same or different models can be connected at will. Each system supports up to 16 modules. In contrast, conventional air conditioners use a fixed unit as the master module of the system; when the master module fails, the entire system fails to work, and the maintenance and commissioning are not convenient. Dual standby operation: A single unit adopts multi-compressor design. When a compressor is faulty, the other compressor in the system can still work normally. In the case of a multi-unit system, maintenance or repair of one unit does not affect the operation of the remaining units Hierarchical start of modules: The unit supports a hierarchical start. This can reduce the unit startup current, reduce the impact on the mains grid, and does not affect the safety of electrical devices in the same area. Modular balance: The unit monitors the running status of each compressor in real time, and intelligently balances the running time of each compressor, to prolong the service life of the unit.
