Ultra-low Temperature Air Source Heat Pump Central Heating System for Energy Saving Buildings
Introduction
The ultra-low temperature air source heat pump is a device that uses air as a low-grade heat source for heating or hot water supply. Its characteristic is that the quasi-secondary compression jet heat pumping heat pump system can ensure the normal heating of the unit at -25 °C, which realizes the possibility of heating the air source heat pump in cold regions.
Features
● Separation of water and electricity, no waste gas, waste residue, safe and reliable, high efficiency and energy saving, and environmental protection.
● Multiple protection, integrated design, and the unit operation is more stable.
● With automatic power-off function of power-off, the unit will automatically start after the call, no need to take care of it.
● When the ambient temperature is low, the microcomputer automatically starts the defrosting function.
● No need for a dedicated computer room to run around the clock.
● Easy installation and low operating and maintenance costs.
- The main components of the unit are all international famous brand components.

Application
◆ domestic hot water, high temperature requirements for water;
◆ bathing, washing, cleaning, sauna, industrial water;
◆ radiator heating, water temperature requirements 55 ~ 65 ° C;
◆ Fan coil heating, the water temperature requires 40~50 °C;
◆ Low temperature floor radiant heating, water temperature 35~10 °C.
The low-temperature and high-temperature operating characteristics make it ideal for use in North cold area.
