EVI DC Inverter air to water heat pump for Heating & Cooling Commercial type
Features Of Commecial DC Inverter Air To Water Heat Pump
Danfoss DC Inverter scroll compressor
30% higher energy efficiency than fixed speed systems
The DC inverter regulation scheme improves the energy efficiency of partial loads by up to 30% compared with the fixed speed system.
As a leader in HVAC technology to meet environmental and energy challenges, Danfoss has developed the VCH115 DC inverter scroll compressor. It features a permanent magnet motor (IPM) design that gives you greater efficiency
1. Optimized scroll compression ratio for heat pump applications, combined with jet technology to optimize efficiency
2. Increase the diameter of the jet pipeline to reduce pipeline vibration
3. Optimize the structural design to reduce the noise of the compressor at high speed
4. The newly designed high-efficiency motor improves the efficiency under partial load conditions
5. The oil filter can reduce the oil churning phenomenon when the compressor is running
6. The compact shape of the compressor is conducive to the layout of the system unit
Modular rotation work
According 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.
Intelligent defrosting technology to reduce heating attenuation
Air-cooled 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 installation
Unit 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-cooled 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.
Building intelligent control to improve management reliability
Modbus 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.
