Dc Inverter Air Source Heat Pump

SUNDEZ DC inverter air to water heat pump is a kind of high efficiency, energy-saving and environment-friendly equipment. It is designed for house warming, with R410a system and optimized DC inverter technology, contributing to stable performance in wide ambient temperature range, especially at lower ambient temperature.

The heating capacity is automatically adjustable by fuzzy control, according to outdoor temperature and indoor heating load. This technology can create a comfortable indoor environment for users, even in colder days.

It can work with any kind of indoor unit such as water fan coil, radiator and floor heating. There is a connection in the controller for indoor thermostati, which can power on or standby the unit, thus saving more energy for users.

Features:
1. DC inverter controller with fuzzy control for house warming.
2. With built-in WILO circulation pump.
3. Stainless steel plate heat exchanger as condenser, hydrophilic-coated fin-tubes as evaporator.
4. The heat exchanger is 30% bigger than that of on/off heat pumps, to meet the adjustable heating capacity, with stable performance at lower ambient.
5. Optional built-in auxiliary heater with ready wiring is available.
6. Strict noise control, with low noise fans, sound jacket for compressors, and noise insulation inside the heat pump case.
