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.

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.
