4 Features Developed from Carrier s leading technologies, the AquaSnap Chiller delivers allinone packaged design with leading efficiency and compact footprint, which make it be a premium solution for medium size commercial or industrial projects. Economical operation Industry leading efficiency at full load thanks to: Optimized air management system including improved heat exchanger design and patented Flying bird IV fans. Specifically designed direct expansion evaporator increases heat exchange performance and features higher flexibility to harsh water condition. Increased energy efficiency at part load The refrigerant circuit includes several compressors connected in parallel. At 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), and dynamic superheat management for better utilization of the evaporator heat exchanger surface. Reduced maintenance costs Maintenancefree scroll compressors. Fast diagnosis of possible incidents and their history via the Touch Pilot control. HFC40A refrigerant is easier to use than other refrigerant blends. Easy and quick installation Integrated builtin hydronic modules: Save efforts on design and installation by integrating all the core components of the hydronic system including centrifugal pumps, water filters, expansion tank, water flow switch, water flow control valve,, etc. Address various customer needs on job site through diversified options of different pressure head and pump quantity (single or dual). Simplified electrical connections A single power supply point without neutral. Main disconnect switch with high trip capacity. Fast commissioning Systematic factory operation test before shipment. Quicktest function for stepbystep verification of the instruments, electrical components and motors. Environmental sound Compact footprint With specifically sized coils and system design, the chiller featuring superior compact footprint that saves valuable installation space is the ideal choice for retrofit projects. The builtin hydronic module brings onestop installation to save significantly save installation space by up to 0% compared to decentralized hydronic system. 0 Ozonefriendly R40A refrigerant Chlorinefree refrigerant of the H depletion potential.

16 Minimum Water Loop Volume For better control of leaving water temperature, the water loop minimum capacity is given by the formula: Capacity = CAP (kw) N Liters Application Normal air conditioning Process cooling Model 0RB 0RB N. 6. 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.
