EVI air to air heat pump for low ambient tempertur

EVI air to air heat pump for low ambient temperture -20C It is specially designed according to cold climate features. Its core philosophy is to solve the user’s home heating during the cold climate in winter and spring, to make cooling in hot summer and autumn. Specification l Low-temperature Enhanced Vapour Injection ( EVI ) compressor, with specially designed economizer and high efficiency heat transfer module, the refrigerant performance has greatly improved in cold climate. l evaporator is 30% bigger than normal, which could ensure higher efficiency and better performance in low ambient temperature. l base frame and external panels made of galvanized powder coating steel. l Intelligent controller, and adjustment by quickmind microprocessor. l Air exchanger ( fins-coil ) with hydrophilic coating. l Thermostatic expansion valve. l Extremely compact structure, easy demountable for access. l Intelligent defrosting function l thermostating heating element for evaporator anti-frosting protection, enable unit to work reliably in hard winter. l With duct piping l Strong heating capacity in low ambient temperature When ambient temperature is -15C, the heating capacity still has 70% of rating heating capacity, and air outlet temperature high up to 35C
