Low temp EVI Split heat pump1

Low Temperature EVI Split Heat Pump

Split EVI air to water heat pump is specially designed for house heating and sanitary hot water in cold area. The ambient temperature range is -25DC to 43DC. It can use safely in -20DC ambient with strong low-temperature heating capacity

Adopting the most advanced low-temperature Enhanced Vapors Injection compressor technology. Split EVI heat pump delivers higher heating capacity at low evaporation temperature thereby better responding to heating requirements than normal air source heat pump, it also results in less supplementary heating to cover the full heating demand on the coldest days. It has been further optimized to enable heat pumps to efficiently produce water temperature up to 60 DC during cold winter time.

Features & Highlights

  • Residential-pool-heat-pump-3Silver welding
    Blueway welding technology let the units system more reliable; in most probably it will avoid the refrigerant leakage
  • Residential-pool-heat-pump-4Smart control
    The units apply intelligent control system: Micro processor based digital controller with LCD display
  • Residential-pool-heat-pump-7High efficiency eco-friendly refrigerant, without ozone depletion
  • Commerial-pool-heat-pump-3Hot gas defrosting
    Blueway adopt “SAGINOMAMIYA” four way valve for the defrosting system. It could defrost itself intelligently & efficiently.
  • Commerial-pool-heat-pump-4EEV technology
    The Electronic Expansion Valve technology Blueway adopt is a very unique and advanced technology. Through intelligent control of refrigerant flow, the use of an electronic expansion valve(EEV) has a number of advantages for the system.
    1. The EEV increase the heating output and the COP
    2. The EEV improves the overall operational reliability
    3. The EEV extends the lifespan of the compressor
  • Commerial-pool-heat-pump-5DC Inverter, Energy Efficiency
    DC inverter tecnology makes the unit get higher efficiency and save more than 30% energy consumption in annual running.
  • Commerial-pool-heat-pump-6Famous brand plate heat exchanger ensure the high efficiency and reliability of the whole heat pump system.
  • Commerial-pool-heat-pump-7High efficiency eco-friendly refrigerant, without ozone depletion
