Water-cooled central air-conditioning system: the use of water-cooled chiller combined with cooling towers, pumps, expansion tanks and other auxiliary facilities for refrigeration operation; the use of boilers for heating operation; the mainframe and the indoor part of the fan coiler connected by a huge water pipe.
Air-cooled heat pump central air-conditioning system: the use of air-cooled heat pump host combined with pumps, expansion tanks, water softening devices such as refrigeration (summer) heating (winter); host and fan coil and other end devices connected by a huge air and water pipe.
Inverter multi-connected air-conditioning system: the system consists of only outdoor unit and indoor unit; the outdoor unit and indoor unit are connected by tiny refrigerant copper pipes. The system is simple and easy to install, intelligent control, and applicable to a wide range of occasions.
Comparison between multi-connected system and water system: Designed cooling capacity: 2000KW; Use: Self-use office building.
Summarize: frequency multi-connected 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%; while using 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 plus building automation system can save nearly 1.4 million of the initial self-control Investment; in addition, if you take into account the savings of each floor of the building height, the savings in civil investment, but also can not be estimated. In short, inverter multi-connected air conditioning is a kind of energy saving, but also save the initial investment of the air-conditioning products with a high performance-price ratio.
Frequency 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 Frequency multi-connected indoor unit temperature control accuracy of up to ± 0.5 ℃; chiller control accuracy of only ± 2 ~ 4 ℃ frequency multi-connected indoor and outdoor unit noise is extremely low, the noise of the indoor unit is only 37dB (A).
1. Inverter multi-connected system does not need technicians for round-the-clock maintenance, which saves daily maintenance cost; traditional central air conditioning system is complicated, and it needs to add at least about 20,000 yuan per year for maintenance labor cost (two persons, 10,000 yuan per person per year).2. Inverter multi-connected system has a powerful self-control system, and the multi-connected indoor unit's remote control, centralized remote control, and CS-NET etc. have 220 kinds of fault codes, and the 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 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 do not have, and indoor and outdoor units of the maintenance costs are also lower; traditional water chillers pipeline scaling is serious, such as not regularly cleaned, the system capacity will be severely reduced The maintenance cost of this part is quite high and the daily maintenance cost of fan coiler and other end equipments is also very high.5. Traditional chiller + boiler there are many safety hazards; inverter multi-connectors never have this problem.6. Inverter multi-connections system annual maintenance cost is very low, compared to the chiller, the annual maintenance cost is only less than 30%.
1 frequency multi-control system: wired wireless remote control, central controller, seven-day timing 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 water cooler is quite low degree of intelligence, not only every day need to be operated by a person to operate the mainframe, 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.
