ZN - Reliable Air Source Heat Pump Manufacturer in China
Air source heat pumps act like a “heat mover,” utilizing the physical properties of a refrigerant. Through a refrigeration cycle and compression process, they absorb heat at low temperatures and release it at high temperatures.
Simply put, they extract heat from the outdoor air and transfer it to a building’s water system (such as underfloor heating, radiators, or water tanks). Of course, in the summer, this process can be reversed to transfer heat from indoors to outdoors, achieving a cooling effect.
ZN is a heat pump manufacturer and supplier from China, established in 2008 with technical roots from Hualing Group and Mitsubishi Electric. We offer a diverse range of heat pump products, including heating and cooling, hot water, swimming pool, heat pump dryers etc.
Smart Power for Perfect Comfort & Savings
Traditional air to water heat pumps are either fully ON or OFF, wasting energy by running at full power even when you need just a little heat—like a car constantly starting and stopping.
All ZN air to water heat pumps are equipped with a DC inverter compressor and an advanced control system. These intelligently adjust power output from 20% to 100% to precisely match your home’s heating and cooling demands.
This ensures smooth, quiet operation, maintains water temperature stability within ±0.5°C, and delivers significant energy savings, keeping your home consistently cozy and comfortable.
Industry-Leading Components for Enduring Quality
All ZN air to water heat pumps feature key components from industry-leading suppliers. For instance, we use DC inverter compressors from Panasonic and Mitsubishi, and plate heat exchangers from Swep, ensuring both high quality and long service life.
ZN Air to Water Heat Pumps Built for Reliability
ZN air to water heat pumps feature advanced, multiple safety technologies for reliable operation. These include compressor high-pressure, low-pressure, and overload protection, plus anti-freeze and automatic winter anti-freeze systems.
Additional safeguards—such as differential pressure flow switch, temperature difference flow, fault protection for temperature sensors, and high-temperature exhaust protection—work alongside other automatic features to minimize downtime and ensure consistent performance.
