Remote management (standard) Aquaforce is equipped with an RS485 serial port that offers multiple remote control, monitoring and diagnostic possibilities. Carrier offers a vast choice of control products, specially designed to control, manage and supervise the operation of an air conditioning system. Please consult your Carrier representative for more information. Aquaforce also communicates with other building management systems via optional communication gateways. A connection terminal allows remote control of the Aquaforce by wired cable: Start/stop: opening of this contact will shut down the unit Dual set-point: closing of this contact activates a second set-point (example: unoccupied mode) Demand limit: closing of this contact limits the maximum chiller capacity to a predefined value Heat reclaim (option): closing of this contact allows heat reclaim mode operation Water pump 1 and 2 control (not available for hydronic module option 116): these outputs control the contactors of one or two evaporator water pumps Operation indication: this volt-free contact indicates that the chiller is operating (cooling load) or that it is ready to operate (no cooling load) Alert indication: this volt-free contact indicates the necessity to carry out a maintenance operation or the presence of a minor fault Alarm indication: this volt-free contact indicates the presence of a major fault that has led to the shut-down of one or several refrigerant circuits Remote management (EMM option 156) The Energy Management Module offers extended remote control possibilities: Room temperature: permits set-point reset based on the building indoor air temperature (with Carrier thermostat) Set point reset: ensures reset of the cooling set-point based on a 4-20 ma or 0-5 V signal Demand limit: permits limitation of the maximum chiller power or current based on a 0-10 V signal Demand limit 1 and 2: closing of these contacts limits the maximum chiller power or current to two predefined values. User safety: this contact can be used for any customer safety loop; opening of the contact generates a specific alarm Ice storage end: when ice storage has finished, this input permits return to the second set-point (unoccupied mode) Time schedule override: closing of this contact cancels the time schedule effects Out of service: this signal indicates that the chiller is completely out of service Chiller capacity: this analogue output (0-10 V) gives an immediate indication of the chiller capacity 06T screw compressor The Carrier 06T screw compressors benefit from Carrier s long experience in the development of twin-rotor screw compressors. The compressor is equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load.a variable control valve controlled by the oil pressure permits infinitely variable cooling capacity. This system allows optimal adjustment of the compressor cooling capacity and ensures exceptionally high stability of the chilled water leaving temperature. Among the other advantages: if a fault occurs e.g. if the condenser is fouled or at very high outside temperature, the compressor does not switch off, but continues operation with a reduced capacity (unloaded mode). The compressor is equipped with a separate oil separator that minimises the amount of oil in circulation in the refrigerant circuit and with its integrated silencer considerably reduces discharge gas pulsations for much quieter operation. 3

All-aluminium micro-channel heat exchanger (MCHE) Already utilised in the automobile and aeronautical industries for many years, the MCHE micro-channel heat exchanger used in the Aquaforce is entirely made of aluminium. This one-piece concept significantly increases its corrosion resistance by eliminating the galvanic currents that are created when two different metals (copper and aluminium) come into contact in traditional heat exchangers. Unlike traditional heat exchangers the MCHE heat exchanger can be used in moderate marine and urban environments (Carrier recommendation). From an energy efficiency point-of-view the MCHE heat exchanger is approximately 10% more efficient than a traditional coil and allows a 30% reduction in the amount of refrigerant used in the chiller. The low thickness of the MCHE reduces air pressure losses by 50% and makes it susceptible to very little fouling (e.g. by sand). Cleaning of the MCHE heat exchanger is very fast using a high-pressure washer. 4

Total heat reclaim (option 50) Suitable for heating, domestic hot water preparation, agriculture and food industry, industrial processes and other hot-water requirements. With the total heat reclaim option it is possible to reduce the energy consumption bill considerably compared to conventional heating equipment such as fossil fuel boilers or electric water tanks. Operating principle If hot water production is required, the compressor discharge gases are directed towards the heat reclaim condenser. The refrigerant releases its heat to the hot water that leaves the condenser at a temperature of up to 60 C. In this way 100% of the heat rejected by the liquid chiller can be used to produce hot water. When the demand for heat is satisfied, the hot gas is again directed towards the air condenser where the heat is rejected to the outside air by the fans. Hot water temperature control is ensured by the chiller Pro-Dialog+ control. Note: Heat reclaim is only possible, if the unit produces cold water at the same time. Condenser water temperature ( C) Minimum Maximum Entering temperature at start-up 12.5* 55 Entering temperature during operation 20 55 Leaving temperature during operation 25 60 Evaporator water temperature ( C) Entering temperature at start-up - 45 Entering temperature during operation 6.8 21 Leaving temperature during operation 3.3 15 * The entering water temperature at start-up must not fall below 12.5 C. For installations with a lower temperature a three-way valve must be used. Note: If the evaporator leaving water temperature is below 4 C, a glycol-water solution or the frost protection option must be used. In part-load operation, the limitation of the condenser leaving water temperature is due to the operating range of the screw compressor. If the condenser leaving water temperature is above the limit value given in the curves on the right, the unit will automatically change over to the mode without heat recovery: Condenser leaving water temperature, C Maximum condenser leaving water temperature, C 6 5 6 0 5 5 5 0 4 5 4 0 3 5 3 0 2 5 2 0 0 5 1 0 1 5 Evaporator leaving water temperature, C Full load Part load limit, approx. 60% Minimum load limit, approx. 30% Part load operating limits (evaporator leaving water temperature = 7 C) 60 55 50 45 40 100 90 80 70 Unit load, % 60 50 40 30 Physical data, option 50 These are the same as for the standard unit except: 30XAS heat reclaim mode 282 342 442 482 Cooling capacity* 278 329 428 475 Heating capacity* 349 411 538 599 Total power input (unit)* 77.7 90.2 120.6 136.0 Total energy efficiency ratio (EER) / 3.58 3.65 3.55 3.49 Total coefficient of performance (COP) / 4.49 4.56 4.46 4.40 Operating weight** kg 3260 3320 4190 4280 Refrigerant charge kg 73 78 90 95 Heat reclaim condenser Flooded shell-and-tube condenser Water volume l 55 55 68 68 Water connection Victaulic Diameter inch 4 4 4 4 Outside diameter mm 114.3 114.3 114.3 114.3 * Nominal conditions: Entering/leaving water temperature: evaporator 12 C/7 C; heat reclaim condenser: 40 C/45 C; evaporator and heat reclaim condenser fouling factor = 0 m 2 K/.

Conformance with EN 60 204 is the best means of ensuring compliance with the Machines Directive 1.5.1. Annex B of EN 60204-1 describes the electrical characteristics used for the operation of the machines. The operating environment for the 30XAS units is specified below: 1. Environment* Environment as classified in EN 60 721 (corresponds to IEC 60721) : outdoor installation* ambient temperature range: 20 C to +55 C, class 4K4H* altitude: 2000 m (see note for table 4.3 in the IOM) indoor installation* presence of hard solids, class 4S2* (no significant dust present) presence of corrosive and polluting substances, class 4C2 (negligible) 2. Power supply frequency variation: ± 2 Hz. 3. The neutral (N) line must not be connected directly to the unit (if necessary use a transformer). 4. Overcurrent protection of the power supply conductors is not provided with the unit. 5. The factory installed disconnect switch(es)/circuit breaker(s) is (are) of a type suitable for power interruption in accordance with EN 60947-3 (corresponds to IEC 60947-3). 6. The units are designed for simplified connection on TN(s) networks (IEC 60364). For IT networks derived currents may interfere with network monitoring elements, and it is recommended to create an IT type divider for the system units that require this and/or a TN type divider for Carrier units. Please consult the appropriate local organisations to define the monitoring and protection elements and carry out the electrical installation. NOTE: If particular aspects of an actual installation do not conform to the conditions described above, or if there are other conditions which should be considered, always contact your local Carrier representative. * The required protection level for this class is IP43BW (according to reference document IEC 60529). All 30XAS units are protected to IP44CW and fulfil this protection condition. 9

Part load performances With the rapid increase in energy costs and the care about environmental impacts of electricity production, power consumption of air conditioning equipment has become an important topic. The energy efficiency of a liquid chiller at full load is rarely representative of the actual performance of the units, as on average a chiller works less than 5% of the time at full load. IPLV (in accordance with AHRI 550/590) The IPLV (integrated part load value) allows evaluation of the average energy efficiency based on four operating conditions defined by the AHRI (Air Conditioning, Heating and Refrigeration Institute). The IPLV is the average weighted value of the energy efficiency ratios (EER) at different operating conditions, weighted by the operating time. IPLV (integrated part load value) Load % Air temperature C Energy efficiency Operating time % 100 35 EER 1 1 75 26.7 EER 2 42 50 18.3 EER 3 45 25 12.8 EER 4 12 IPLV = EER 1 x 1% + EER 2 x 42% + EER 3 x 45% + EER 4 x 12% The heat load of a building depends on many factors, such as the outside air temperature, the exposure to the sun and the building occupancy. Consequently it is preferable to use the average energy efficiency, calculated at several operating points that are representative for the unit utilisation. ESEER (in accordance with EUROVENT) The ESEER (European seasonal energy efficiency ratio) permits evaluation of the average energy efficiency at part load, based on four operating conditions defined by Eurovent. The ESEER is the average value of energy efficiency ratios (EER) at different operating conditions, weighted by the operating time.
