Absorption Chiller V Series Absorption Chiller-Heater Type V Series Appearance Absorption Chiller Steam Type V Series Appearance Excellent Performance with More Energy Savings, Excellent Efficiency at a Much Lower Cost. At Hitachi, basing ourselves on cooling technology and know-how acquired over many years, we put into practice our latest proprietary technology. Through the use of large chilled water/cooling water temperature differential adaptability and provision of a high-functionality microcomputer as a standard control panel, superior reliability and durability are realized, while achieving running efficiency. As an item of new-age cooling equipment Hitachi's one step ahead chiller contributes to the realization of total energy-saving and low cost in air-conditioning system. 1. Low Energy and Low Cost -By means of the new cooling water flow system (ACA flow), a standard frame size accommodating large chilled water/cooling water temperature differential is realized. By improvement of control of solution circulating quantity, a 10% improvement in average load factor is achieved in partial load characteristics (as compared with previous models). 2. High Reliability -A high functionality microcomputer control panel with a complete set of preventive maintenance and abnormality forecast functions is a standard feature. Standard cooling capability realizing up to 4,000 hrs/yr operation. 3. Superior Operability and Easy Maintenance -Operating condition or abnormalities are quickly shown on easy-to-see liquid crystal digital and LED displays. Full automation of purging operation is realized by use of water ejector purging device which does not use electricity and can purge out any non-condensible gases. Compatible with air conditioning system interfaces and supports introduction of remote supervision system. 4. Large-Temperature-Differential System. -By using the large-temperature-differential system, the circulating volumes of chilled and cooling water can be reduced. The large-temperature-differential system reduces power needed for circulating air and water, because of reduced volumes of the draught from the air conditioner fan and of the circulating water from the hilled and cooling water pumps. In addition, it makes such facilities as air ducts and chilled/cooling water pipes smaller, and also reduces the initial cost for them. 5. High Efficiency Operation. -In addition to the parallel flow system, Hitachi's new proprietary flow technology (ACA flow technology) is employed in the cooling water system. Without increasing the chiller frame size, the adaptatin to large chilled/cooling water temperature differentials has been made possible. Accordingly, energy-saving and low operating cost (by reduction of start-up and other operating costs) are achieved not only for the chiller but for air-conditioning as well. 6. High Performance Microcomputer. -Electric power saving with large-temperature differential chilled/cooling water system. 1. Steam Double Effect Absorption Chiller Details 2.
