Product Description
packaged heat pump type rooftop air conditioner Description:
1. 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 conditioner Features:
1. It is packaged air conditioner which integrates condensing part, evaporating part & control part into a 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 save indoor space, user will only need to install the duct, no need to connect refrigerant pipe work, it works 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 to atmospheric agents.
2. Direct expansion coils with condensate drain tray.
Hermetic compressor
1. 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 fan
1. 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 panel
1. Electric panel consists of breakers and contactors for compressors and fan motors, phase sequence relay and other necessary protection devices for the main components
2. Easy operation line controller
3. Cooling/Heating/Auto
3. Error indication
4. Timing on/off
Optional
1. Economizer with fresh, return air dampers and fresh air hood
2. Free cooling function for low ambient temperature
3. Low ambient control device for operation of outdoor units at ambient temperatures from less than 20C down to -10C
4. BMS devices
4. T3 (Tropical climate)
5. Condenser coil guard
6. Roof curb
7. Metal / aluminum filter
8. Air pressure switch for indoor fan
9. High static condenser fan option with sealed + drain condensing section
10. Optional water heating coil
11. Metal or plastic mesh on condenser coil
12. Optional supply / return air configurations
13. Upgraded evaporator fan motor drives
14. G4 filter, plate and bag filter
