Detailed description of the invention
Embodiment:
Consult Fig. 1, a kind of fan coil units, comprise be provided with water inlet pipe 2 and return pipe 3 coil pipe group 1, be arranged on blower fan 7 in coil pipe group 1 and blower fan 8, drive the DC brushless motor 6 of blower fan 7 and blower fan 8, be arranged on return pipe 3 and be provided with flow balance valve 4, the wireless temperature controller 14 of controller 5, return pipe 3 is provided with the return water temperature sensor 9 be connected with controller 5, in coil pipe group 1, be provided with the first temperature sensor 10 and the second temperature sensor 11 of connection control device 5 respectively, the rotational speed control module input of DC brushless motor 6 is connected with controller 5.Controller 5 is provided with the wireless module 12 of band antenna 13, and wireless temperature controller 14 is connected by wireless module 12 with on controller 5.
Return water temperature sensor 9 can Real-Time Monitoring transmit return water temperature signal to controller 5, the first temperature sensor 10 in coil pipe group 1 and the second temperature sensor 11 can be monitored the temperature of circulating current in time and be transferred to controller 5, controller 5 can export DC signal to the rotational speed control module of DC brushless motor 6, the rotating speed controlling DC brushless motor 6 realizes the electrodeless variable-speed of rotation speed of fan, and wireless temperature controller 14 can by wireless module 13 to controller 5 input temp setting value and Boiler pressure control parameter.Controller 5 is according to the return water temperature collected and room-temperature signal, and the aperture of reduced temperature set point adjustment flow balance valve 4, on the basis that guaranteed flow controls, carries out the adjustment of room temperature further.
The fan coil units of the present embodiment is arranged on indoor, and wireless temperature controller 14 is without the need to fixed installation.For refrigeration, after starting fan coil units, following room temperature regulative mode can be adopted:
By the switch activated fan coil on wireless temperature controller 14, after controller 5 receives wireless signal, start DC brushless motor 6 and drive blower fan 7 and blower fan 8 to rotate.Flow balance valve 4 can set the maximum cooling water flow of circulation, thus sets the maximum heat exchange amount of this tail-end blower fan coil pipe unit.The return water temperature value that controller 5 is monitored according to return water temperature sensor 9, contrast return water temperature setting value, below peak flow values, the aperture of optimizing regulation flow control valve 4, such as when return water temperature exceedes setting value, controller 5 can leave the aperture of large flux control valve 4 gradually, but the circling water flow rate now flowing through coil pipe group 1 is still less than maximum cooling water flow, and the energy consumption of this fan coil units does not exceed setting value; When return water temperature is lower than setting value, the corresponding control of controller 5 turns down flow balance valve 4, reduces circling water flow rate, makes return water temperature return range of set value; Regulated by the aperture of monitoring return water temperature to flow balance valve 4, the cold of exchange and the thermic load of this fan coil units can be made fast to match, thus reduce the fluctuation of Cooling capacity exchanging, reduce system energy consumption.When return water temperature change convergence is steady, illustrate that overall heat exchange amount is close to thermic load, this Time Controller 5 can according to the house temperature of monitoring, and the aperture of fine setting flow balance valve 4, makes room temperature tend towards stability as early as possible further, improves the comfort level of user's impression.The room-temperature signal that controller 5 can be monitored according to the second temperature sensor 11, export direct current signal, accurately control the rotating speed of DC brushless motor 6, the electrodeless variable-speed realizing blower fan 7 and 8 regulates, make air force realize electrodeless change, improve the comfort level of user's impression further.Other regulative modes according to actual needs, can set corresponding program and realize in controller 5.
Wireless temperature controller 14, without the need to in-site installation, wirelessly just can realize temperature setting and air quantity setting, greatly simplify field erected difficulty.
Above-listed detailed description is illustrating for one of the utility model possible embodiments, this embodiment is also not used to limit the scope of the claims of the present utility model, allly do not depart from the equivalence that the utility model does and implement or change, all should be contained in the scope of the claims of this case.
