Description

Rooftop package units with economiser cycle (optional for standard series), VRV AHU and AHU are generally used for warehouse/retail facilities:

1. Rooftop package unit is a system that contains all the components in one concise unit and provide conditioned air for large open space applications. This system can be also paired with Economiser kit that allows modulations of outdoor air and return air mixture for even further reduction of total operational load pf air conditioning systems.

Rooftop package unit (UAYQ series) with optional economiser cycle kit and CO2 control to provide high conditioned air volumes to large spaces. The economiser cycle can provide free cooling and/or reduced heating load based on motorised damper control for energy savings during colder ambient conditions. Available in Standard and Premium range. Premium range (UAXYQ series) is powered by VRV heat pumps condenser units.

Rooftop package solution may also include night cooling mode, humidity sensors and control, duct temperature sensors, connectivity to the third-party controls with basic operations for standard series and extensive range of functions for premium series.

2. VRV AHU (Air handling unit) is a system that pre-condition outdoor air for ventilation purposes as required by the Building code and reduces operational load of air conditioning system. It consists of VRV outdoor units and air handling unit (filters, heat exchangers, dampers, fans in a framed casing) designed based on the client’s requirements.

VRV AHU utilises the VRV outdoor condenser units and can be scaled to the required capacity of outdoor air processing. Two series available – Standard series and Outdoor Air series. VRV AHU solution allows to select the system based on the client’s requirements and maintain precise indoor air conditions.

3. Custom modular AHU solutions are also available based on project requirements.

Single split and VRV systems can be used for office areas, where:

Single Split is a system that consists of one indoor unit connected to outdoor unit and delivers air conditioning to single zone interior spaces at an affordable price.
The Daikin VRV system is a multi-split type air conditioner (one outdoor unit with multiple indoor units) for commercial buildings that uses variable refrigerant flow control developed by Daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building.

Heating: -5 to 15 CDB

Both series enable flexible ductwork design, long piping runs, outdoor installation can be achieved if required as well as custom configuration to suit site constraints. VRV condensers can be installed in independent location from the AHU unit that helps overcome projects spacing and weight constrains.

Package units are designed to be installed outdoors with its standard corrosion treatment and insulation. AHUs can be installed not only indoors but also outdoors with optional corrosion treatment and certain insulation thickness.

Limitations on Use

Min entering temperature during heating operation: Packaged units 16 CDB; VRV AHU Standard series 14 CDB, outdoor series -5 CDB.
Rooftop Package units have basic functionality comparing to VRV AHU systems
Certain connection ratio and max piping length rules for VRV AHU should be considered and met
Daikin systems should not be used in corrosive indoor environments and high humidity applications (ex. swimming pools). For corrosive outdoor environments, additional treatment is required such as Blygold.
Outdoor VRV units are not recommended to install in enclosed spaces unless required air intake volume and exhaust provided to and from the space

Other Performance Attributes

Economiser kits are available for the standard series of rooftop package units to suit the 150 to 300 class. These kits consist of motorised return and outside air dampers electrical box and weather hood
VRV AHU solution comes with the option of VRT smart technology. This technology allows the fluctuation of the refrigerant temperature. This provides better thermal comfort of the supply air temperature provided to the occupants and results in energy savings
Blygold Coatings (on request) will prolong the life of the unit
