Description
Technical field
The utility model belongs to air-conditioning technique field, is specifically related to a kind of outdoor machine of air-conditioner defrost checkout gear.
Background technology
Air-conditioner set in the process heated, because needs constantly carry out heat exchange to outdoor and indoor, beyond the easy frosting of outer coiler of machine; Once the outer coiler frosting of outer machine, will the duty of outer machine be had a strong impact on, the use of air-conditioning is affected.So air-conditioning, when heating, because the outer coiler of outer machine exists the problem of frosting, generally all needs the frost removed by defrost on outer coiler.
Be all the defrost being controlled unit by timing defrost in current most air-conditioner set, namely after the running time of air-conditioner set and the temperature of outer coiler arrive a certain particular value respectively, unit just starts defrost.After defrost completes, unit enters running time of defrost next time and decision condition still remains unchanged.The incomplete place of this control is, when outside air humidity is lower, such as in the north of China, after the unit operation regular hour, little or the basic frost-free of the outer coiler of outer machine, but now, according to the defrosting condition of setting, unit still can perform a defrost process, in fact wastes energy; When outside air humidity is higher, such as in the south of China, unit is after the operation regular hour, the frosting of the outer coiler of outer machine may be very thick, have a strong impact on the operation of air-conditioner set, and after the defrost process be fixed, defrost of may all having no idea to realize completely, this accumulation long, the outer coiler of outer machine still can frosting.Therefore, there is defrost condition and fix in traditional control method, there will be the problem of " the frequent defrost " or " defrost is incomplete " wasted energy, have a strong impact on the use of air-conditioning.
For prior art Problems existing, the utility model provides a kind of outdoor machine of air-conditioner defrost checkout gear, the temperature of outer coiler is obtained by temperature sensor, detected the power output of outer machine blower fan by current measuring device simultaneously, whether the temperature of outer coiler and the power output of blower fan are entered defrost as air-conditioning, whether terminate the decision condition of defrost, accurately can judge outer machine frosting situation, the decision condition of outdoor machine of air-conditioner self adaptation defrost and the intensity of defrost can be made, there will not be and enter defrost process without the need to defrost, also the incomplete problem of defrost can be avoided to the full extent, there is timely defrost, energy-conservation advantage.
Utility model content
The purpose of this utility model is to provide a kind of outdoor machine of air-conditioner defrost checkout gear, and overcome prior art and start the judgment basis terminated by means of only the rigid condition arranged as defrost, the frequent defrost of existence wastes energy and the incomplete problem of defrost.
For this reason, the utility model provides a kind of outdoor machine of air-conditioner defrost checkout gear, comprising: for measure outer coiler temperature outer coiler temperature sensor, for measure blower fan operating current current measuring device, for receiving outer coiler temperature sensor and blower fan work current measurement data and transferring data to the control panel of air-conditioner controller and the power supply for powering to device; Wherein, outer coiler temperature sensor is arranged on the outer wall of outer coiler, and the temperature-sensitive head of temperature sensor is close on outer coiler, and outer coiler temperature sensor and control panel are electrically connected by wire; Current measuring device series connection is linked on the motor of blower fan, is electrically connected by wire and control panel; Control panel is electrically connected by wire and air-conditioner control system, and power supply and each several part are electrically connected with supply of electrical energy.
Outer coiler temperature sensor adopts integrated digital temperature sensor or thermistor.Integrated digital temperature sensor can make measuring circuit simple, but cost is relatively high.Thermistor can designing measuring circuit flexibly, selects different thermistor type according to demand, can adjust the precision of measurement.
The temperature of outer coiler is obtained by the temperature sensor be arranged on outer coiler, and the power of blower fan obtains operating current by the current sensing means be arranged on blower fan, calculates power.Certainly, can directly by the operating current of the blower fan of acquisition as a reference, and not need current conversion to be power yet.When outer coiler temperature is lower than the temperature value of setting, when the duration that simultaneously power of fan exceedes the value of setting exceedes certain threshold range, thinking that outer machine frost occurs, now whether can start defrost according to arranging selection.
After starting defrost, if when outer coiler temperature exceedes the temperature value of setting, thinking that the frost of outer coiler is dissolved completely, now whether can terminate defrost according to arranging selection.
The beneficial effects of the utility model are mainly manifested in: by the measurement of the temperature of external coiler, the monitoring of power of fan, as judging defrost whether condition, can accurately understand the need of defrost process, economize energy.Meanwhile, owing to measuring the real-time information obtained, under the prerequisite of the outer coiler of protection, the application of various environment can be adapted to.
