basic introduction 

    Water system type is a small semi-centralized fan coil system, the indoor load all by the hot and cold water units to bear. Each room fan coil connected to the hot and cold water unit through the pipeline, by the provision of hot and cold water for cooling and heating. Water system layout flexibility, independent regulation is good, comfort is very high, to meet the complex use of scattered rooms, the need for independent operation of each room. In addition, the current new water system air conditioning is the floor heating system application of one of the best solutions, through the effective combination of floor heating, the use of low water temperature large area of low temperature radiation heating, than the traditional fan coil heating system More comfortable and energy saving.

    How this works

    The water-cooled central air-conditioning unit includes four parts, a compressor, a condenser, a throttle device, an evaporator and a refrigerant. The refrigerant flows in a high temperature and high pressure of the refrigerant (refrigerant) coming out of the four parts, Cooling down, the condenser through the cooling water system will be the heat to the cooling tower discharge, the refrigerant continues to flow through the throttle device into a low temperature and low pressure liquid, through the evaporator, endothermic, and then compressed. In the evaporator at both ends of the chilled water circulation system, the refrigerant in the suction heat will reduce the chilled water temperature, so that low-temperature water to the customer side, and then through the coil to heat exchange, the cold wind blowing.

    Energy efficiency ratio for large area use, the greater the use of more energy efficient

    (Water heat capacity is relatively large) small units use

    (Frequency conversion technology, the use of lower circumstances have advantages)

    Comfortable water is not easy to lose, the temperature difference between the small use of a long time indoor air drying, there are uncomfortable

    Whether to support the floor heating is the best floor heating program does not support

    Circulation system Water machine (water circulation system) Fluorine machine (freon and other refrigerant circulation system)

    Reliability Dual loop design, can use multiple compressors, even if a compressor circuit failure can continue to work, reliable scroll compressor, the unit running long life. Generally a single inverter compressor, outdoor unit and indoor unit control all connections, once a machine failure, the entire system can not be used, only a compressor, take a long time to run.

    Safety refrigeration system focused on the external machine, safe and reliable, the water system working pressure is low, even if the indoor water system part of the leak, it is easy to find leakage leaks throughout the system, and the work pressure is very high, the probability of leakage, and not easy Find the leak.

    Service life The life of the water machine is 20 years

    After-sales service performance is relatively stable, low cost of late maintenance A few years ago to use better, 7-8 years after the problem, maintenance costs higher.

    Heating effect combined with enthalpy and other technologies, water system heating range up to -15 ℃, the other with the floor heating effect better fluorine system heating in -5 ℃ below poor, and can not be applied to warm

    Thermal efficiency is heating up slowly

    Summary of principles

    Central air conditioning water quality intelligent control device, from the system for the return of the main pipeline were connected to the small pipeline to the device to form a circular pipeline. The device through the high-precision on-line water quality testing equipment, the cycle of water quality changes, and control the dosing pump automatically real-time quantitative added to the water to achieve the corresponding water treatment effect. At the same time, the device to detect the concentration of circulating cooling water to achieve quantitative automatic sewage, to ensure that the concentration of cooling water in a reasonable range, in order to give full play to the role of pharmaceuticals, saving sewage water.
