The air conditioner water coil pipe frost crack proof device that the utility model proposes runs and the inoperative period at water pump of air conditioner, all can effectively prevent air conditioner water coil pipe by bursting by freezing, thus in guarantee air-conditioned room, newly the wind demand moment meets design load requirement, thus avoid because water coil is produced leakage accident by bursting by freezing.
Accompanying drawing explanation
Fig. 1 is the air conditioner water coil pipe frost crack proof device structural representation of the utility model one embodiment.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the utility model is described in further detail.Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the technical solution of the utility model, and not should be understood to restriction of the present utility model.
The utility model provides a kind of air conditioner water coil pipe frost crack proof device.As shown in Figure 1, in the utility model one embodiment, described air conditioner water coil pipe frost crack proof device comprises: the feed pipe 11 and the return pipe 12 that are connected with air conditioner water coil pipe (in Fig. 1 AHU shown device), and described air conditioner water coil pipe is provided with temperature sensor 8; Be arranged at the bypass pipe 13 between feed pipe 11 and return pipe 12, bypass pipe 13, feed pipe 11, air-conditioning water pond and return pipe 12 form a bypass circulation, bypass pipe 13 are provided with successively the first valve 51, water circulating pump 6, check-valves 2 and the second valve 52; Be arranged on feed pipe 11, be positioned at the electric heater 1 of described bypass circulation; Be arranged on return pipe 12, the electric control valve 7 be positioned at outside described bypass circulation; Be arranged at the first differential pressure pickup 10 between bypass pipe 13 and return pipe 12; For the control unit (not shown) of controlled circulation water pump 6, electric control valve 7 and electric heater 1.
Preferably, the air conditioner water coil pipe frost crack proof device that the utility model proposes also comprise be arranged on described feed pipe 11, the filter 3 be positioned at outside described bypass circulation, the front and back end of filter 3 is connected to the second differential pressure pickup 4, filter 3 can avoid the dirt in water pipe to enter into air conditioner water coil pipe, play the effect preventing from blocking, and the second differential pressure pickup 4 is for being detected the pressure difference value at filter 3 two ends, when described pressure difference value exceedes a certain setting value, send alarm signal to described control unit, notify that administrative staff clean filter 3.Preferably, temperature sensor 8 is arranged at first row water pipe place, described water coil windward side; Return pipe 12 exit is provided with water flow switch 9.
The utility model proposes air conditioner water coil pipe frost crack proof device operation principle for: when temperature sensor 8 elicite temperature lower than a certain low-temperature values preset time, then send alarm signal to described control unit, then detect the pressure difference of the first differential pressure pickup 10, divide following two kinds of situations according to detected pressure difference and then carry out follow-up control mode:
If the pressure difference that situation one first differential pressure pickup 10 elicites is greater than a certain preset value, then described control unit controls standard-sized sheet electric control valve 7, after running a period of time, if temperature sensor 8 when eliciting temperature value still lower than the above-mentioned low-temperature values preset, then described control unit opening electric heater 1; Run after a period of time, if temperature sensor 8 elicite temperature value when reaching a certain high temperature values preset, close electric heater 1; Rerun after a period of time, if temperature sensor 8 when eliciting the low-temperature values of temperature value again lower than above-mentioned setting, described control unit again opening electric heater 1 heats, as temperature sensor 8 elicite temperature value still higher than the high temperature values of above-mentioned setting, air-conditioner set controls to reply ordinary control mode, and namely the adjustment aperture of electric control valve 7 accepts the control of wind pushing temperature or return air temperature value; If temperature sensor 8 when eliciting the low-temperature values of temperature value again lower than above-mentioned setting, enter next circulation pattern.
Situation two, as the first differential pressure pickup 10 the pressure difference that elicites be less than above-mentioned preset value time, described control unit ON cycle water pump 6 and electric heater 1; Run after a period of time, if temperature sensor 8 elicite temperature value when reaching the high temperature values of above-mentioned setting, close electric heater 1; Rerun after a period of time, if temperature sensor 8 when eliciting the low temperature of temperature value again lower than above-mentioned setting, described control unit is opening electric heater 1 again.Constant stream signal is had, workflow described in system control mode patten transformation to situation one as water flow switch 9 senses air-conditioning return pipe.
The pressure difference elicited when the second differential pressure pickup 4 is greater than a certain setting value, sends alarm signal equally to described control unit.
This device runs and the inoperative period at water pump of air conditioner, all can effectively prevent air conditioner water coil pipe by bursting by freezing, thus ensures that in air-conditioned room, the new wind demand moment meets design load requirement, thus avoids because water coil is produced leakage accident by bursting by freezing.
