Horizontal Rooftop Packaged Unit

23444556666 app

Bueco rooftop packaged units are applied in the industrial and commercial fields such as hotel, supermarkets, authorized dealing shop, office building and factory workshop. They perfectly connect many characteristic of large-sized central a/c, such as convenience, comfort, high-class , the simplicity and flexibility. 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 form “Zero” temperature difference. Besides, outdoor fresh air can be absorbed. The air path can connect with indoor ornament which is completely hidden and does not occupy any space. It has become a new generation of products of central a/c and traditional commercial a/c.

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

It can reach control modes: cooling, heating, ventilation and optional free cooling. It also has the functions of timing on-off and failure display.

4. Excellent performance

World well-known brand of main parts are used. To guarantee the rational match of the unit, strict performance testing is done. Besides the unit runs steady and the vibration and noise are effectively controlled by the use of multi-vane pitch centrifugal fan, world-known high efficiency compressor and the elaborative-designed controller, motor, etc.

5. Quiet operation and Convenient maintenance

Reach the lowest noise of the a/c room. The a/c units are placed far from the a/c area which meets the demand of indoor low noise to the greatest degree. The adoption of high efficiency and low noise centrifugal fan makes the quiet operation come true.

Free cooling logic:

1. When it is heating, the fresh air damper is closed, and return air damper is 100% open;

2. When it is cooling:

      a. When indoor room temperature (temperature set) – outdoor temperature ≥ 4 ℃,fresh air damper is 100% open, and return air damper is 100% closed,only the evaporator fan is running to blow air into room;

      b. When 0 ℃ ≤ indoor room temperature (temperature set) – outdoor temperature< 4 ℃ ,both fresh air damper and return air damper are closed, and the unit is not running;

      c. When indoor room temperature ( temperature set) – outdoor temperature < ℃,the return air damper is 100% open,and fresh air damper is 100% closed,then the compressor, condensing fan and evaporator fan will work normally to blow cool air into room.

Heat recovery

Bueco heat recovery fresh air unit turns the silent building into a house with aspiration function, all the pollutant such as smoke, dust and odor etc. will be cleared with the exhaust and supply air system, so the indoor air quality is clean and comfortable. The city residents spend their time more than 90% in room, the air-conditioned room air quality is critical to health. Bueco heat recovery fresh air unit becomes the “lung” of modern building practically, it is a new fresh air healthy and environment friendly product.

The application of nano film technology, horizontal reverse counter flow technology, antistatic & maintenance free technology and attenuation technology, Bueco solved the low efficiency problem of traditional heat recovery unit, total heat recovery efficiency up to 75%. The heat recovery fresh air unit reduces the air conditioning load, initial investment and system operation cost.
