rooftop packaged unitProduct DescriptionRooftop 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. Product
