Embodiment

[0019] Such as figure 1 As shown, the control method for alleviating the frosting of the outdoor condenser of the air conditioner in the present invention is completed by adopting the following measures:

[0020] 1. First detect the temperature T1 of the indoor evaporator coil, and judge whether T1 is greater than or equal to N, where N is the temperature range of the indoor evaporator coil under normal heating conditions, generally satisfying 31°C≤N≤50°C, for different air conditioners System, N has different values. In this example, 38°C is more suitable for N. If T1≥38°C, it means that the heating effect of the air conditioning system is normal, then perform step 2, that is, detect the temperature of the outdoor condenser coil; and if T1 < 38°C, indicating that the heating effect of the air-conditioning system has declined, so it is necessary to defrost the outdoor condenser, return after defrosting, and continue to detect the temperature of the indoor evaporator coil;

Abstract

The invention relates to an air conditioning control technology and discloses a control method for relieving frosting of an outdoor condenser of an air conditioner, which solves the problem that the comfort of the air conditioner is influenced by a frost treating mode of the outdoor condenser in the prior art. The technical scheme has the main points of: detecting the temperature T1 of a coil pipe of an indoor evaporator; judging whether the T1 is greater than or equal to N, wherein the N is greater than or equal to 31 DEG C and is less than or equal to 50 DEG C; if so, continuously detecting the temperature T2 of the coil pipe of the outdoor condenser; otherwise, defrosting the outdoor condenser; and when the T2 is less than or equal to 0 DEG C and retains a certain time, regulating the rotating speeds of motors of indoor and outdoor fans, and delaying the frosting treatment of the outdoor condenser, Through the treatment, after retaining indoor normal heating effect, the frosting time is delayed. The invention is suitable for delaying the frost control of outdoor condensers of all air conditioners.

Description

technical field [0001] The invention relates to air-conditioning control technology, in particular to a control method for alleviating frosting of an outdoor condenser of an air-conditioning machine. Background technique [0002] With the improvement of people's living standards, air conditioners have entered thousands of households as an essential member of the family. The heating or cooling process of the air conditioner is actually the process of heat exchange. When the heat pump is running, the outdoor condenser absorbs the heat from the outdoor side, and the air conditioning system moves the heat to the indoor side for heat release. When the outdoor temperature is low, frost will form on the outdoor condenser, which will affect the heat absorption effect of the outdoor side, thereby affecting the heating effect. In the traditional technology, the treatment method for frosting is: when the frosting reaches a certain level, the air conditioning system will change directi...
