Features

Lower GWP

Utilising R32 Refrigerant, Temperzone's Econex Packaged Units enable a 73-76% reduction of Global Warming Potential (GWP) per kW of cooling when compared to R410A units.

Economy

Each Econex (Pro) unit in this series uses a variable capacity inverter, which generally uses less energy than alternative types of compressor.

Efficient

As most air conditioners operate at part load for the vast majority of the time, it makes sense for each unit to incorporate an inverter scroll compressor which is very efficient at part load. Part load efficiency can be even further enhanced by indoor fan part load operation at low loads (e.g., 75% airflow equates to 55% power use). Each indoor air fan incorporates a high efficiency electronically commutated (EC) motor. Large heat exchange coils incorporate inner grooved (rifled) tube for better heat transfer.

Better Comfort

Variable speed technology enables fine tuning of the system, which ultimately delivers temperature stability and therefore better comfort to the occupants in the air-conditioned space. The system also includes head pressure control logic, which enables the system to compensate for outdoor ambient temperatures below 20°C on cooling cycle, and above 15°C on heating cycle.

Intelligence (Econex Pro)

Econex Pro incorporates intelligent technology. Its software understands the surrounding environment and self-adjusts to maintain required temperature and humidity levels. The unit can operate to: (1) maximise part-load efficiency, (2) maximise performance, or (3) balance efficiency and performance. The variable capacity inverter compressor technology can provide close comfort control of the room temperature. Each OPA unit has capacity higher than its nominal available for fast response when well away from set point at start-up, and an energy-saving low capacity turn-down. Econex/EconexPro feature a dynamically balanced forward curved fan with a variable speed EC motor. This variability enables fine tuning to match the supply air requirements. These EC motor fans have a fully integrated speed control that enables soft starting. Fan speed can be stepped to your own requirements or continuously variable using a 0-10V DC control signal.

Quiet

Each integral high efficiency EC fan motor can vary from zero to full speed. This allows slow ramp up with no sudden noise change. The outdoor coil design permits low fan speeds and hence low noise levels. The compressor is in a weatherproof built-in, insulated compartment to minimise noise. The indoor air section is also insulated for noise attenuation, thermal protection of the air stream, and to minimise exterior condensation.

Durable

The cabinet is constructed from high-grade galvanised steel - baked polyester powder coated (to AS 4506:2005; colour Grey) for all-weather protection (IP44 / IPX4). External fasteners are marine-grade SKT® coated steel. The units include a baked polyester powder coated drain tray. Heat exchange coils comprise aluminium corrugated plate fins on mechanically expanded rifled copper tube. Both the indoor and outdoor coils' fins are pre-epoxy coated for extra protection in corrosive environments, e.g., salt-laden sea air. Fan motor bearings are sealed for life so as not to incur regular maintenance. Coil protection guards protect against hail, accidental damage, or vandalism.

Easy Access

These packaged outdoor units are typically installed on a rooftop, where maintenance access is relatively easy during operating hours.

Improves Indoor Air Quality

The indoor air fan ventilates the building by distributing conditioned air throughout the building, with an option for fresh air introduction via Economiser control. (Note: Air filters, economy cycle dampers, and fresh air openings are not included with the unit and should be installed in the external duct system).

Low Maintenance

Commissioning and maintenance costs are reduced through the use of a fan that requires no pulley and belt adjustments or changes like traditional fans.

Inverter Compressor

Each high efficiency variable capacity inverter compressor is hermetically sealed, quiet running, and supported on rubber mounts to minimise vibration. Inverter compressor provides the economy of part load performance.

Soft Starting

EC motors and inverter compressors are soft starting, therefore have none of the problems associated with high in-rush current.

Insulation

Closed-cell foam insulation has been used in the indoor air section to ensure no particles are introduced into the air stream. Both indoor and outdoor air chambers are insulated to prevent external condensation forming on the cabinet exterior. The insulation is foil-faced and meets fire test standards AS 1530.3 (1989) and BS 476 parts 6 & 7.

Unit Control System

Econex: The control system is comprised of a Temperzone UC8 controller which looks after factory settings, status reporting, and alarms display. An external controller is also required.

Econex Pro: The control system is comprised of one Carel c.pCO mini master controller and one Temperzone UC8 slave controller. The master controller looks after the setpoints, operation modes, factory settings, status reporting, scheduling, BMS settings, and alarms display. The unit's fully integrated controls enable it to operate as a 'stand alone' unit. An optional Carel pGN (pn 201-000-867) wired remote display is available for location up to 50m from the unit, enabling easier servicing.

Control Option

The EC fan motor is controlled variably (within a restricted range, p10) by a 0-10 volt DC signal that can be supplied either by a BMS system, or the internal c.pCO Controller (Pro only). The units are BMS compatible, with multi-unit control possible via Modbus RTU, Modbus TCP/IP or BACnet/IP. Refer to Temperzone for other protocols available. Units can also be run as turn-key operation with no BMS connection required.

Extended Capability

Inverters are particularly suitable for applications requiring high proportions of fresh air, VAV, and close control. Supply air temperature control is also possible using BMS or other controls. Refer to Temperzone for capacity range variation options.

System Protection Features

HP and loss of refrigerant protection.
Anti-rapid cycle timer and internal overload for compressor protection.
Circuit breaker control circuits.
Time-and-temperature controlled electronic de-ice switch prevents icing up of the outdoor coil during heating cycle.
Frost protection on cooling cycle.
Sensor fault indication.

Self Diagnostics

Each Unit Controller (UC8) has a LED display to indicate faults and running conditions. No need to connect pressure gauges. Econex: A non-specific/common fault indicator is included for interface to external systems. Econex Pro: Faults can be displayed on the master controller and communicated through BMS (both general and specific).

Lower Installation Costs

This type of air conditioner is compact and self-contained in comparison to Split Systems which require long interconnecting piping. OPA units are quick to install.

Wiring

The electrical supply required is: 3 phase 400 V a.c. 50 Hz with neutral and earth. The compressor crankcase heater requires a 24 hr power supply. The control panel is fully wired ready to accept the main power supply. Each system complies with the requirements of the Regulatory Compliance Mark (RCM) for electrical safety (AS/NZS 60335.2.40) and EMC (AS/NZS CISPR.14). For your convenience, a single phase auxiliary power outlet (10A) is included in the electrical box.

Plant Room Use

Each unit is supplied with a relatively low static (<25 Pa) condenser fan. Nominal outdoor airflow and correct unit clearances, along with no air recirculation, must be maintained in order for the unit to achieve its performance specification.

Configurations

Horizontal supply & return air versions
Upward supply & horizontal return air versions

Optional Equipment

TZT-100 wired wall t/stat control
Remote Service Interface Display (pGN) - can be located up to 50m from unit using a 6 wire RJ12 telephone cable (not supplied)
Electronic control systems for temperature and economiser (economy cycle)
Fresh air temp./humidity sensor (field fitted)
CO2 sensor 0-10V (field fitted)
Drain sensor (field fitted)
BACnet gateway controller (supplied separately)

External Economiser Control

For external in-duct dampers: If the outdoor air enthalpy (heat content) is below that of the space condition, a fresh air damper opens and a return air damper closes to provide cooling. Operating costs are reduced as free cooling is obtained. (Note: A separate spill air facility in the building may be necessary for when the return air damper is closed.) Fresh air dampers close to a minimum setting and return air dampers open before normal compressor operation resumes.

This option for Econex units requires external dampers c/w motors and cowl; sensors and controls by others.

This option for Econex Pro units requires external dampers (c/w motors) and an additional temperature & humidity sensor for the outside air, but includes Economy Cycle control functionality.
