Frequency central air conditioning and traditional air-cooled heat pump units and water-cooled units than the comparison of annual operating costs can save more than 35 ~ 50%; at the same time, the use of frequency air conditioning can save 70% of the annual maintenance costs; without special air conditioning management personnel, this cost can save 20,000 yuan per year; of course, if the entire building using frequency multi-connected machine plus building automation system can save nearly 1.4 million of the initial investment in self-control; In addition, if you take into account the savings of each floor of the building height, the savings in civil engineering investment, but also can not be estimated. In short, inverter multi-connected air conditioning is a kind of both energy-saving, but also save the initial investment of the air-conditioning products with a high performance-price ratio. Inverter multi-connected air conditioning can be independently operated according to the customer's personal needs of the indoor unit, the most suitable for their own room temperature inverter multi-connected indoor machine temperature control accuracy of up to ± 0.5 ℃; chiller control accuracy of only ± 2 ~ 4 ℃ inverter multi-connected indoor and outdoor machine noise is extremely low, the noise of the indoor machine is only 37dB (A).
Key points: chiller load below 20% can not be turned on normally, such as the use of 250RT chiller, 20% of the load of about 50RT (about 150,000kcal / h), the use of the area of about 1,860m2. in higher than 20% but lower than 100% load, the unit deviates from the optimal operating conditions, the operating efficiency is very low.
Maintenance is more convenient: 1. Inverter multi-connected does not require technicians for 24/7 maintenance, saving daily maintenance costs; traditional central air-conditioning system is complicated and requires at least about 20,000 yuan of additional maintenance labor costs per year (two people, 10,000 yuan per person per year). 2. Inverter multi-connected system's auto-control system is powerful, multi-connected indoor unit remote control, centralized remote control, CS-NET, etc. The system has 220 kinds of fault codes, CS-NET network monitoring can also predict the occurrence of faults in the company, in principle, can completely avoid the occurrence of faults; traditional water chillers have only a small number of fault codes.3. Inverter multi-connected system is convenient to add; traditional water chillers can not be added.4. Inverter multi-connected pipeline maintenance costs are not, indoor and outdoor machine maintenance costs are also lower; traditional water chillers pipeline scaling is serious, such as not regularly Cleaning, the system capacity will be seriously reduced, and this part of the maintenance costs are quite high and fan coiler and other end equipment daily maintenance costs are also very high. 5. traditional chiller + boiler there are many safety hazards; inverter multi-connected absolutely no such problem. 6. inverter multi-connected system of the annual maintenance costs are very low, compared to the chiller, the annual maintenance costs are only less than 30%.
High degree of intelligence:
1. Frequency multiplexing control system: wired wireless remote control, central controller, seven-day timer controller, CS-NET air conditioning management system, etc.; 2. Automatic fault detection and measurement system: CS-net air-conditioning network control system; 3. Specific control features and content of the samples and technical information; 4. The traditional chiller degree of intelligence is quite low, not only every day, you need to specialize in the operation of the host, but also if you want to Access to building automation system, the system configuration and installation is very difficult, and the cost is very expensive.
