R515b Low Gwp=299 High Temperature Air Source Heat Pump

AirValley High temperature air source heat pump water heater, With R515B refrigerant with lower pressure, low GWP only 299. Maximum water output temperature 95 deg CProduct DescriptionHoney-well R515B new low GWP(only 299) refrigerant, Non-flammable, for high temperature heat pump, commercial or industry use:Intelligent 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.  Speciall designed Weishans brand compressor, specially tested with R515B refrigerant for two yearsMultiple 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.High precision electronic expansion valveHigh precision electronic expansion valve: use electronic expansion valve for controlling, reach 500 steps adjustment, adjust super heat degrees accurately, achieve high efficiency operation system.Fin Heat ExchangerThe blue hydrophilic aluminum foil fin heat exchanger adopts cross type multi-flow path design to make the heat exchange more uniform; the internal thread copper tube design has higher heat transfer efficiency; at the same time, the hydrophilic fins are not easy to form water droplets, Spreading into a uniform water film completely on the surface of fins, eliminates the generation of water bridges, which greatly improves the heat exchange capacity and heat exchange efficiency between the aluminum foil and the flowing air.Water 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.
