2 Turn To The Experts Founded by the inventor of modern air conditioning, Carrier is the world s leader in high-technology heating, air-conditioning and refrigeration solutions. Carrier experts provide sustainable solutions, integrating energy-efficient products, building controls and energy services for residential, commercial, retail, transport and food service customers. Carrier is a part of UTC Build ing & Industrial Systems, a unit of United Technologies Corp., a leading provider to the aerospace and building systems industries worldwide. With a broad portfolio of advanced technical patent awards, our global R&D center in Shanghai develops innovative heat, ventilation and air-conditioning (HVC) solutions. In 998, Time magazine named Dr. Carrier oneof its 0 most influential builders and titans of the 0 th century.

3 Features The quasnap Puron liquid chillers/air-to-water heat pumps are designed for commercial (air conditioning of villa, supermarket, office, hotel hospital etc.) or industrial (lowtemperature process chillers etc.) applications. Benefits Environment sound refrigerant HFC-0 of zero ozone depletion potential. Standard unit with hydronic module (except for 0RB67/80) including all necessary hydronic components, easy and fast installation to save time, space and money. Low operating sound with no intrusive low-frequency noise, creates a better working/living environment. Electronic expansion valve (EXV) utilization, several compressors connected in parallel lead to more economical operating cost. Exceptional endurance tests ensure superior reliability to minimize chiller down-time. Environmental sound Ozone-friendly HFC-0 refrigerant - Chlorine-free refrigerant of the HFC group with zero ozone depletion potential. - Very efficient - gives an increased energy efficiency ratio Leak-tight refrigerant circuit. - Brazed refrigerant connections for increased leaktightness. - Reduction of leaks as no capillary tubes and flare connections are used. - Verification of pressure transducers and temperature sensors without transferring refrigerant charge. Easy and fast installation Integrated hydronic module(except for 0RB67/80) - Centrifugal high or low-pressure water pump (as required). - Single or dual pump (as required) with operating time balancing and automatic changeover to the back-up pump if a fault develops. - Water filter protects the water pump against circulating debris. - High-capacity membrane expansion tank ensures pressurization of the water circuit. - Thermal insulation and anti-freeze protection down to -0 o C by using an electric resistance heater. Simplified electrical connections - single power supply point without neutral (except for 0RB67/80). - Main disconnect switch with high trip capacity. - Transformer for safe V control circuit supply included. Fast commissioning - Systematic factory operation test before shipment. - Quick-test function for step-by-step verification of the instruments, electrical components and motors.

4 Quiet operation Compressors - Low-noise scroll compressors with low vibration level. - The compressor assembly is installed on an independent chassis and supported by anti-vibration mountings. - Dynamic suction and discharge piping support minimize vibration transmission (Carrier patent). - coustic compressor enclosure reduces radiated noise emission (option). Condenser section - Condenser coils in V-shape with an open angle allows quieter air flow across the coil. - Low-noise th generation Flying Bird fans (Carrier patent) enjoy quieter operation and never generate intrusive low-frequency noise. - Rigid fan mounting preventing start-up noise (Carrier patent). Economical operation Increased energy efficiency at part load - The refrigerant circuit includes several compressors connected in parallel. t part load, around 99% of the operating time, only the compressors that are absolutely necessary operate. - The electronic expansion device (EXV) allows operation at a lower condensing pressure (EER and COP optimization). - Dynamic superheat management for better utilization of the evaporator heat exchange surface. Reduced maintenance costs - Maintenance-free scroll compressors. - Fast diagnosis of possible incidents and their history via the Pro-Dialog Plus control. - HFC-0 refrigerant is easier to use than other refrigerant blends. bsolute reliability State-of-the-art concept - Cooperation with specialist laboratories and use of limit simulation tools (finite element calculations) for the design of the critical components, e.g. motor supports,suction/ discharge piping etc. Exceptional endurance tests - Corrosion resistance tests in salt mist in the laboratory. - ccelerated ageing test on components that are submitted to continuous operation: compressor piping,fan supports. - Transport simulation test in the laboratory on a vibrating table. The test is based on a military standard and equivalent to 000 km by truck.

5 Pro-Dialog Plus Control Pro-Dialog Plus combines advanced control logic with simple operation. The control system monitors all operation parameters all the time and precisely manages the operation of compressors, electronic expansion devices, fans and water pumps for optimized energy efficiency. User-friendly interface User interface with synoptic diagram for intuitive display of the principal operating parameters: number of compressors operating, suction/discharge pressure,compressor operating hours, set-point, air temperature, entering/leaving water temperature. Ten menus for direct access to all machine commands, including fault history, allowing fast and complete chiller diagnostics. dvanced control function Unit provides different control mode including LOCL/REMOTE/CCN. Remote control function including: Unit ON/OFF, dual set point control, -level demand limit control, user safety interlock, water pump operation control, operation indication, circuit alarm and alert etc. utomatic reset of leaving water temperature based on return water temperature or outside air temperature to ensure optimized energy efficiency. Control algorithm prevents excessive compressor cycling and permits reduction of the water quantity in the hydronic circuit (Carrier patent). utomatic compressor unloading in case of abnormally high condensing pressure. If an abnomal incident occurs (e.g. fouled condenser coil, fan failure), quasnap continues to operate, but at reduced capacity. Powerful diagnostics quick test of all unit components and control points to verify the correct operation of every switch, circuit breaker, contactor etc. at the start of the chiller. Real-time monitor all the operation parameter, and alarm when necessary. Control system is facilitated with RS8 serial communication port for remote diagnosis or special diagnosis tools. Sufficient safety measures Password protection in case of mishandling. Unit is protected against: Loss of refrigerant charge, reverse rotation, low chilled water temperature, current imbalance, compressor thermal overload, excessive air temperature, high pressure, electrical overload, loss of phase. Group control Master/slave control of two chillers connected to automatically balance operating times, and also automatically conduct change-over in case of a unit fault. Communication with other Building Management System (BMS) by selecting BCnet/J-Bus/LonTalk gateway.

Where Cap is the nominal system cooling capacity (kw) at the nominal operating conditions of the installation. This volume is necessary for stable operation and accurate temperature control. It is often necessary to add a buffer water tank to the circuit in order to achieve the required volume. The tank must be internally baffled in order to ensure proper mixing of the liquid (water or brine).refer to the examples below. Bad Good Bad Good Field Control Wiring. mm MX.
