Integrated thermostat Introduction of a dedicated concentrator, the new requirements of a control valve, the valve power supply with the temperature control valve door, and heat meters Law biggest difference is: the valve needs to be powered. (1) If the electric gate valve 24V electric power according to the power calculating each valve 3W, the current of each valve in the closed state consumes: 125mA, if a building is calculated according to the valve 100, and 1 / Valve 3 is closed, then the current consumption reached: 4.2A. (2) If a 24V electric motor-driven ball valve, each valve in the driving condition, the current is about 30mA, if a building has 100 valves, and there may be overlap 1/5 valve operation, then the supply current to reach : 0.6A. 2. If using an electric power supply protection valve gate, then the total supply current valve will reach 4.2A, in order to deal with individual cases more valves parallel action, should be used at least 10A switching power supply. Such a large current, power requirements and line impedance is very low, if the line without protective measures, short-circuit current will be a great moment to 0.1 ohm source resistance calculation, instantaneous short circuit current will reach 240A, during construction and system operation , the probability of occurrence of a short circuit lines are very large, if not instantaneous short circuit current restrictions, there may be cause of the accident and therefore the use of thermostatic valve door after asking concentrator can provide current monitoring and protection functions. 3, power handling electric valve using cold normally open electric gate is the biggest advantage: Under the conditions of a mains failure, the valve is in the open state. After cooling, this can ensure that households heating unaffected. However, if the use of electric valve, when the mains power failure, there is always a part of the ball valve is closed, if the power a long time, it will bring great impact on users of heating, can cause users to power outages, broken hot this Species worse situation. Thus requiring the use of electric valve temperature control system, must use a spare battery. Requirements concentrator can charge the battery when the power cut is detected, the thermostatic valve can open all doors on the bus, be able to send information to the server outage. 4, good debugging capabilities using thermostatic valve gate system debugging more difficult than doubled, so the focus should be able to provide effective debugging tool, otherwise the scene will be very difficult to debug.
