22KW 220V～/50Hz Inverter LOW temperature heat pump heating and cooling system designed for optimal comfort and energy efficiency.

Scientific research shows that from the perspective of health and comfort, the ideal temperature in winter is between 18-20°C. The ideal heat distribution shows a temperature distribution from floor to ceiling with vertical reduction, which can keep the feet warm and clear-headed. The heat of the floor heating rises from the foot, so that the temperature of the whole indoor space is hierarchically distributed. It conforms to the theory that TCM health is "warm and cool". The floor heating is an ideal heating method without hot air, which is beneficial to the body to maintain moisture. At the same time, it has a promoting effect on rheumatism and asthma.

• Compressor: Choose world-famous brand rotary type or fully enclosed vortex compressor, featuring low noise, low vibration, high efficiency, and long service life. For units with multiple compressors, automatic unloading at partial load effectively saves energy and avoids frequent start-up.
• Water Side Heat Exchanger: Utilizes high-efficiency shell tube or threaded casing heat exchanger with small volume, light weight, easy disassembly, convective heat conduction, and maximum working pressure of 45kgf/cm². Insulated with 10mm PE to prevent energy loss.
• Air Side Heat Exchanger: Features integral hydrophilic finned inner threaded tube design with large windward area, high heat transfer efficiency, oxidation and corrosion resistance. Hydrophilic fins reduce condensation and frosting, ensuring sufficient heating capacity in cold winter and normal operation for heating and defrosting in low temperatures.
• Low Noise Fan: Uses domestic famous brand motor with axial impeller design, bearing that doesn't overheat, oil-free maintenance, anti-aging blades that don't deform. Fans undergo strict static balance experiments for optimal working point, efficiency, and noise level.

Under ideal weather conditions, heat pump water heaters produce three times the energy used to power the heat pump. In other words, heat pump water heaters use one-third of the electricity of conventional electric water heaters. The average residential customer would save significantly on monthly energy costs using a MEIDIBAO heat pump water heater.
