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.
