Abstract
The utility model provides a refrigerator condenser fan control system which comprises a condenser and a condenser fan. The condenser and the condenser fan are mounted in a refrigerator condenser cabin, the condenser fan and the condenser are adjacent, an air outlet of the condenser fan faces the condenser, a controller and a temperature sensor are arranged in a refrigerator, the controller is used for controlling the condenser fan to work, the temperature sensor is used for detecting the environmental temperature, and the temperature sensor is electrically connected with the controller. The temperature sensor is used for acquiring the environmental temperature outside the refrigerator and feeding back the environmental temperature to the controller, the controller controls the condenser fan to work by receiving environmental temperature signals detected by the temperature sensor, the condenser fan can run at different rotational speeds according to different signals and is started or stopped, and cooling of the refrigerator at different environmental temperatures is accelerated, so that annual energy consumption of the refrigerator is reduced.
Description
Technical field
The utility model relates to the household electrical appliance refrigerator, particularly a kind of condenser for refrigerator fan control system.
Background technology
At present, the condenser of wind cooling refrigerator generally is divided into built-in and external, and traditional external condenser for refrigerator is generally by the condenser fan forced ventilation, the gaseous refrigerant that accelerates in the condenser is condensed into liquid state, its control method is generally as follows: when the rising of refrigerator the temperature inside the box reaches the compressor start condition, compressor energising operation, simultaneously condenser fan energising starts.But, because the very large relation of the heat radiation of external condenser and environment temperature, so there are two drawbacks in the control method of condenser fan and the synchronous start and stop of compressor: first, can increase the refrigerator energy consumption of the whole year, the second, under the environment temperature of high temperature, the refrigerator cooling velocity is slow.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of condenser for refrigerator fan control system that refrigerator is faster cooled off and reduce annual energy consumption is provided.
The technical scheme that realizes the utility model purpose is: a kind of condenser for refrigerator fan control system, comprise the condenser and the condenser fan that are installed in the freezer compressor cabin, the adjacent setting of condenser fan and condenser, and the air outlet of condenser fan is towards condenser, also be provided with the controller of control condenser fan work and the temperature sensor of testing environment temperature in the refrigerator, temperature sensor is electrically connected with controller.Adopting increases controller and temperature sensor, temperature sensor gathers the temperature of refrigerator external environment, and feed back to controller, the ambient temperature signal that controller transmits by receiving temperature sensor again, and cooperate the compressor operating state, control the work of condenser fan, condenser fan can be according to the different different rotating speeds of signal operation, or open or stop, accelerate refrigerator cooling velocity under varying environment, thereby reduce the annual energy consumption of refrigerator.
Further, controller also is electrically connected with the compressor of refrigerator, makes the work running of refrigerator more reasonable.
Further, temperature sensor is arranged on the refrigerator top, can accurately gather environment temperature.
The beneficial effects of the utility model are: adopting increases controller and temperature sensor, temperature sensor gathers refrigerator external environment temperature, and feed back to controller, controller is controlled the work of condenser fan again by receiving temperature sensor testing environment temperature signal, condenser fan can be according to the different different rotating speeds of signal operation, or open or stop, accelerate refrigerator cooling velocity under the varying environment temperature, thereby reduce the annual energy consumption of refrigerator.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, controller 1, temperature sensor 2, condenser fan 3, condenser 4, minimum temperature value T1, maximum temperature value T2.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of condenser for refrigerator fan control system, comprise the condenser 4 and the condenser fan 3 that are installed in the freezer compressor cabin, condenser fan 3 tuyere lines are to condenser 4, and rotating speed is adjustable, also is installed with controller 1 in the refrigerator body, and the temperature sensor 2 that is installed in refrigerator body top testing environment temperature, temperature sensor 2 is connected with controller 1 signal of telecommunication, start and stop and the rotating speed of controller 1 control condenser fan 3.Controller 1 also is electrically connected with the compressor of refrigerator, and compressor is electrically connected with condenser, makes the work running of refrigerator more reasonable.
Realize that a kind of method of the present utility model is: temperature sensor 2 gathers environment temperature and sends to controller 1, controller 1 is judged according to the temperature signal that receives, according to the duty of judged result cooperation compressor, the start and stop speed of control condenser fan 3 runnings.
Be preset with minimum temperature value T1 and maximum temperature value T2 in the controller 1, T1 is less than T2, and concrete control method is as follows:
1) ambient temperature value that collects when temperature sensor 2 is during less than T1, and controller 1 sends corresponding signal to condenser fan 3, and condenser fan 3 shuts down;
2) ambient temperature value that collects when temperature sensor 2 is between T1～T2 the time, and controller 1 sends corresponding signal to condenser fan 3, and condenser fan 3 is with the synchronous start and stop of compressor and middling speed running;
3) ambient temperature value that collects when temperature sensor 2 is during greater than T2, and controller 1 sends corresponding signal to condenser fan 3, and condenser fan 3 is with the synchronous start and stop of compressor and run up.
Record according to experiment, minimum temperature value T1 is value between 8 ℃～12 ℃, and wherein T1 gets 10 ℃ of the bests, and maximum temperature value T2 is value between 30 ℃～34 ℃, and wherein T2 gets 32 ℃ of the bests.
The below uses cooling velocity contrast under each environment temperature of the utility model front and back:
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model.Be that all equalizations of doing according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
