35kw Commercial DC Inverter Air Source Heat Pump for Hot Water

AirValley Commercial EVI DC Inverter Air source heat pump water heater, With Dan-foss DC Inverter compressor & R410A refrigerant, Maximum water output temperature 60 deg C, Lowest working ambient temperature -35 deg CProduct DescriptionDetails of Dan-foss DC Inverter compressorIntelligent defrosting technology to reduce heating attenuationAir source heat pump units are prone to frosting when the air density is low and the humidity is high. The air-cooled heat pump module unit can accurately judge the defrosting timing according to the main parameters of the heating operation and the load change, so as to achieve defrosting with frost and normal heating without frost, and can perform forced manual defrosting according to the actual situation.Modular design, more flexible installationUnit modules of different capacity specifications can be freely combined, and a maximum of 16 units can be connected in parallel, with strong compatibility and scalability. According to the site characteristics of the installation site, the user can choose a variety of combination connection methods to realize the parallel use of 1-16 modules, and the maximum cooling capacity is as high as 2080kW, fully meeting different needs. The air source module units of the same system are started in stages and run in a balanced manner, reducing the impact of the starting current of the units on the power grid.Modular rotation workAccording to the load conditions of the system, the unit rotates the module units that are turned on first, and distributes the running time of each module unit in a balanced manner, which greatly improves the reliability and service life of the unit.Building intelligent control to improve management reliabilityModbus is an open protocol that is widely used, especially in BMS building control systems. The unit can be connected to the BMS system through the Modbus protocol to realize remote control of multiple air cooling and heat pump modules.    Multiple protection functionsTo ensure the safe operation of the system, a modular structure is adopted, and the units are started in stages to reduce the impact of the starting current of the units on the power grid. The unit is equipped with high and low pressure switches, antifreeze protection devices, water flow switches, overload protection devices, power supply phase sequence protection devices, etc., and is equipped with an operation control device. When a fault occurs, the controller will automatically alarm in real time.Wifi function for optionControl your heat pump in your smartphone anywhere, anytime.Top quality Sensata pressure sensorExcellent precision, excellent mechanical resistance and EMC protection characteristics, meeting the most stringent application requirements under various pressure conditions.FUJIKOJI Electronic expansion valveWater side heat exchangerHigh-efficiency shell & coil heat exchanger with both cooling and heating is adopted, with water in the tube and fluorine outside the tube. High heat exchange efficiency, small size, excellent water quality, strong antifreeze ability, stable and reliable.   Company ProfileAirValley is a heat pump manufacturer focusing on OEM and ODM.
