Air cooled rooftop air conditioner.2. Cooling capacity: 8kw to 90kw, a variety of choices.3. High external pressure.4. Applicable to residential and commercial buildings, hotels, and scientific research units, factories and enterprises and so on.packaged heat pump type rooftop air conditionerFeatures:1. It is packaged air conditioner which integrates condensing part, evaporating part & control part intoa whole unit, firstly promoted & applied in South America, North Europe & Australia.2.It is air cooled direct evaporation & expansion air conditioner, has no need on cooling water &chilled water system, dispenses with cooling tower/cooling water pump/chilled water pump, relative pipe work, electric control & terminal equipments, saves user investment.3. It integrates evaporating part & condensing part into a whole unit which is installed outside to saveindoor space, user will only need to install the duct, no need to connect refrigerant pipe work, itworks under intellectual control without special care.Application range:It is mainly applied to factories, schools, auditoriums, warehouses, etc.Structure:1. Panels and frame are made from galvanized steel protected with polyester powder painting to ensure total resistance toatmospheric agents.2. Direct expansion coils with condensate drain tray.Hermetic compressor1. High efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.2. Ripple type acoustic insulation for compressor section, and thermal insulation for coil and fan section, low noise.Centrifugal fan1. Forward curve centrifugal fans for air treatment section and axial fans for condensation section.2. Front, side and underside air discharge of the treatment unit.3. High external pressure, long air supply distance.Electric panel1. Electric panel consists of breakers and contactors for compressors and fan motors, phase sequence relay and other necessary protection devices for the main components2. Easy operation line controller3. Cooling/Heating/Auto3. Error indication4. Timing on/offOptional1. Economizer with fresh, return air dampers and fresh air hood2.
