Product Description

rooftop packaged unit

Product Description

Rooftop packaged units are applied in the industrial and commercial fields such as hotel, supermarket, authorized dealing shop, office and workshops.
The new design makes use of the space module. The features of small sized commercial modern building space, making the cool and heat air spread into each room averagely to "zero" temperature difference. Besides, outdoor fresh air can be absorbed into the room. The air path can connect with indoor ornament which is completely hidden and doesn't occupy any space. It has become a new generation of HVAC product.
Rooftop packaged unit is a kind of integral air-conditioning equipment with its own cold (heat) source and air cooling. Its refrigeration, heating, humidification, air supply, air purification, electrical control, etc. are all assembled in one structure. Rooftop packaged unit can be divided into various types according to different functions: cooling only type, heat pump type, electric heating type, constant temperature and humidity type, and purifying type.

The heating methods include: heat pump heating, electric heating, steam heating, hot water heating, gas heating, etc.;
Th humidification methods include: electrode humidification, dry steam humidification, electric heating humidification, high-pressure micro mist humidification, wet film humidification, etc.

The unit can add flow-sharing section, medium-efficiency filter section, muffler section, air outlet section, etc. as required.

Air inlet and outlet direction: horizontal air supply, top air supply, horizontal return air, top return air, side return air, etc.

Rooftop packaged unit composed of the condenser and the refrigerant expansion direct evaporator, does not need cooling water and cooling water system, saves the cooling tower, water pump and corresponding pipelines, and some electronic control devices. It is widely used for inconvenient installation of water circuits. It is widely used to adjust the temperature, humidity, cleanliness and other parameters of large and medium-sized workshops and workshops in inconvenient water system installation and water resource shortage areas.

The direct expansion air-conditioning unit itself has its own compressor. Because the liquid refrigerant in its refrigeration system is directly evaporated (expanded) in the evaporator coil to absorb heat and cool the air outside the coil, it becomes a direct expansion type.

As the rooftop packaged unit is directly installed on the top of the building, the structure and surface treatment of the unit take into account corrosion, sun protection, and rain protection. The unit can be installed on the roof or on an outdoor platform.

Because the unit adopts air cooling, no cooling water system is required, so it is easier to install than water chillers, and is especially suitable for areas with scarce water sources. Due to the overall structure, the length of the refrigeration system pipeline is greatly shortened, thereby greatly improving the reliability of the system. Because the whole machine is installed outside the house, it does not occupy valuable indoor space, and there is no noise during indoor operation.

Main Features
1. Various products and wide application 
The series of Rooftop units include many different specifications which can completely meet the demand of home and commercial places and offer you a comfortable and pleasant environment.
2. Complete air system, simple and hygiene, less components, easy maintenance. The flexible and concise design makes the maintenance very simple. Disassembling several bolts from any side of the unit can repair any part of the unit.
3. Microcomputer intelligent controller can reach four control modes: cooling, dehumidifying, and ventilation. It also has the functions of timing on-off and failure display.
