Product advantages

R32 Heat Pumps Operating in Low Ambient Temperatures (-35°C)

R32 heat pumps are designed to operate in a wide range of ambient temperatures, including those as low as -35°C. This capability is crucial in regions with harsh winters. However, to ensure optimal performance and efficiency in such extreme conditions

R32 EVI air source heat pumps with full DC inverter technology:
R32 EVI air source heat pumps, paired with full DC inverter technology, offer a highly efficient and environmentally friendly heating and cooling solution. The full DC inverter enables precise control of the compressor speed, optimizing energy efficiency and providing stable indoor temperatures. The R32 refrigerant contributes to reduced environmental impact due to its low GWP. Combined, these technologies result in a system that is both powerful and sustainable.

Low noise of R32 high-efficiency tank heat pump:
Inverter technology: Adopting full DC inverter technology, the compressor runs smoothly and has lower noise.
Optimized design: Sound insulation materials are used inside the unit, and the air duct design is reasonable to reduce wind noise.
Refrigerant characteristics: R32 refrigerant is charged in small quantities, which reduces the noise generated by the flow of refrigerant.
In short, R32 high-efficiency tank effectively reduces operating noise through technological innovation and optimized design, providing users with a quiet and comfortable indoor environment.

Working Principle

EVI Monoblock Air-to-Water Heat Pumps: A Working Principle
EVI Monoblock air source heat pump is an upgraded version of air source heat pump. It uses frequency conversion technology to more accurately control the flow of refrigerant, allowing the heat pump to work efficiently in a colder environment. The working principle is actually similar to that of ordinary air source heat pumps:
Heat absorption: Absorb heat from outdoor air.
Refrigerant circulation: The refrigerant circulates between the compressor, condenser, expansion valve, and evaporator, continuously absorbing and releasing heat.
Heating: Transfer the absorbed heat to water to provide hot water or heating.
The advantages of EVI are:
Higher efficiency: Especially in low temperature environments.
Wide range of applications: Can adapt to more extreme climate conditions.
More stable operation: Frequency conversion technology makes operation smoother.
In short, EVI makes air source heat pumps more "smart", more flexible to adapt to various environments, and provide more stable heating and cooling effects.
