The beneficial effects of the utility model: the utility model is by proportioning valve that at water inlet pipe an aperture to be set be 0-100%, the accurate control of temperature difference of the temperature that can set according to indoor temperature and user enters the flow of the water of surface cooler, avoided the fluctuation of temperature too big, influence comfort level, controller and temperature sensor are controlled the rotating speed of blower fan in addition, thereby can make indoor temperature reach the temperature that the user sets fast, and help the stable of indoor temperature.
Description of drawings
Fig. 1 is the structural representation (overlooking) of the utility model fan coil;
Fig. 2 is the structural representation (main looking) of the utility model fan coil.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further set forth.
As depicted in figs. 1 and 2, fan coil of the present utility model comprises surface cooler 1, surface cooler 1 is provided with water inlet pipe 11 and outlet pipe 12, water inlet pipe 11 is provided with the proportioning valve 3 of control flow of inlet water, the aperture of proportioning valve is 0-100%, surface cooler 1 windward side one side is fixed with a wind wheel 21, and the blower fan 23 that drives wind wheel 21 rotations, also can be to be fixed with two wind wheels 21 and 22, wind wheel 21 is connected with the output shaft 231 at blower fan 23 two ends respectively with 22, passing ratio valve 3 can accurately be controlled the flow that enters the water inlet in the surface cooler 1, and the bottom of surface cooler 1 is provided with the condense water disk 6 that is used to accept condensed water.
In order to realize the efficient control of air quantity and flow, the utility model can also be on the basis of above-mentioned fan coil, at the indoor temperature sensor 4 that a controller 5 is set and is used to monitor indoor temperature, controller 5 is connected with temperature sensor 4, blower fan 23 and proportioning valve 3 respectively, controller 5 is by the indoor temperature result of C.T sensor 4 monitorings and the indoor temperature of user's setting, the rotating speed and proportioning valve 3 apertures of control blower fan 23.
The utility model has been realized the intelligent stepless variable air rate and the discharge that turns cold on the basis of conventional fan coil, all control functions and blower fan function of stepless speed regulation all are integrated in controller 5 inside, by the output control signal, accurately the aperture of control ratio valve 3 and the rotating speed of blower fan 23 guarantee that indoor temperature is constant.
Temperature sensor 4, proportioning valve 3 aperture 0-100% control and blower fan 23 stepless speed regulations, temperature control function all is integrated in the controller inside that is loaded on the indoor wall, concrete control procedure is as follows: the user presses after the start button above the controller 5, controller 5 reads indoor Current Temperatures by temperature sensor 4, compare with setting value, if deviation greater than 2 ℃ of default values (according to user's request, this value can be revised by controller 5), controller 5 is passed to the DC signal of a 10V of proportioning valve, proportioning valve 3 apertures are transferred to maximum, 7 ℃ cold water passing ratio valve 3, water inlet pipe 11, enter into surface cooler 1, flow out through outlet pipe 12 again.When proportioning valve 3 is opened, the control signal of 23 1 maximum (top) speeds of controller fan, blower fan 23 high speed rotating are got up, and drive the wind wheel 21 and 22 that is connected on the same axis and rotate synchronously.Outdoor air enters wind wheel 21 and 22, blows into the air that comes from wind wheel 21 and 22 and passes gap between surface cooler 1 fin again, through the cold cold water of table cold is passed to air in surface cooler 1 flows outside, thereby the temperature of room air is lowered.Surface cooler 1 is a heat exchange mechanisms that is with much very thin aluminium fin on the copper pipe of bending, and the cold water circulation is arranged in copper pipe, and there is air circulation in the surface cooler outside.Thereby cause indoor air temperature to reduce, the cold water temperature in the absorption chamber behind the heat raises, thereby reaches the purpose of refrigeration.If indoor temperature is higher than the deviation of setting value in 2 ℃, the aperture of proportioning valve 3 reduces automatically, blower fan 23 rotating speeds that drive wind wheel 21 and 22 reduce automatically, control mode with proportional integral, in optimum state, finally cause indoor temperature to reach the required temperature of user the speed setting of the aperture of proportioning valve 3 and blower fan 23.During heating mode, the proportional algorithm counter-rotating realizes variable water volume and variable air rate by the aperture of control ratio valve 3 and the rotating speed of blower fan 23 equally, with the heat transferred room air of hot water in the pipe dish, realizes heating up, and finally reaches design temperature.
Utilize variable air rate flux-variable fan coiler of the present utility model, indoor temperature can be stabilized in setting value ± 1 ℃ in, that has avoided that conventional fan coil pipe unit caused when operation departs from setting value on a large scale, in addition, this fan coil units can guarantee indoor temperature neither can be too cold can be too not hot yet, greatly reduce the consumption of the energy, and, this kind unit can also move the fast-refrigerating program when starting, automatically regulate air-supply air quantity and cold water flow, reach after the setting value, fan speed is transferred to reduced levels automatically, reduce noise greatly, create a quiet comfortable environment to the user.
