Embodiment Construction
[0018] Such as figure 1 and figure 2 As shown, the energy-saving control device of the fan coil unit in the central air conditioner includes an electric regulating valve M, a relay, a room card switch S2 and a thermostat and other components. The electric regulating valve M is installed in the fan coil unit, which can control the conduction and shutdown of the internal cooling and heat medium of the fan coil unit. The electric regulating valve M is controlled by electric current to open and close the valve. In this embodiment, the electric regulating valve M is a floating electric regulating valve.
[0019] The working power supply of this device is an ordinary 220V AC power supply.
[0020] The room card switch S2 and the thermostat are installed in the room. After the relay coil J is connected in series with the room card switch S2 and the thermostat switch S1, it is connected between the live wire and the ground wire. Obviously, only when the room card switch S2 and t...

The energy saving control device of blower fan coil pipe in the central air conditioning is of the air conditioning technical area, it has solved the energy wasting problem which happens when the central air conditioning uses blower fan coil pipe. It consists of in the blower fan coil pipe, room card switch and thermostat set in room and relay; relay coil and room card switch and thermostat switch connected in series are connected between earth wire and live wire; normally closed contact of the relay is connected between live wire and closed contact of live wire and motor driven control valve, and its normally open contact is connected between live wire and open contact of the live wire and motor driven control valve; grounding contact of the live wire and motor driven control valve is connected to earth wire. The device which controls the live wire and motor driven control valve by room card switch and thermostat controls the circulation of cooling and heating medium in the blower fan coil pipe, saving energy, and it has the properties of simple structure, convenient installment.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, in particular to an energy-saving control device for fan coil units in central air conditioners. Background technique [0002] In the energy consumption of restaurants, the energy consumption of air conditioning system accounts for 60-70%. According to statistics, the air-conditioning system load of buildings such as restaurants has about 80% of the time below 50% of the year, and its air-conditioning equipment works under partial load most of the time. How to carry out energy-saving control on air-conditioning equipment and ensure the energy-saving operation of air-conditioning equipment under partial load is the core issue of reducing energy consumption of air-conditioning and realizing energy-saving of air-conditioning. [0003] There are fan coil units at the end of the central air conditioner. At present, when the central air conditioner is partially not in use, the fan can only b...
