Embodiment Construction

[0044] The present invention firstly provides an air conditioner, figure 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention. see figure 1 , the air conditioner includes a compressor 10 , an indoor heat exchanger 20 , a throttling device 30 and an outdoor heat exchanger 40 connected in sequence to form a main refrigerant circuit. Specifically, the compressor 10 is configured to compress and discharge the refrigerant sucked in by it. The compressor 10 can suck low-pressure refrigerant, compress the low-pressure refrigerant to form high-temperature and high-pressure gaseous refrigerant, and discharge the gaseous refrigerant. The throttling device 30 is configured to throttle and reduce the pressure of the refrigerant flowing out of the indoor heat exchanger 20 . The throttling device 30 is preferably an electronic expansion valve. The indoor heat exchanger 20 is arranged such that the refrigerant in it exchanges heat ...

Abstract

The invention relates to an air conditioner device and a control method thereof. The control method comprises the steps that when the air conditioner device is in a heating mode, whether the defrosting condition is met or not is judged, and if yes, a heating defrosting mode is conducted; in the heating defrosting mode, part of refrigerants discharged by a compressor are promoted to directly flow towards an outdoor heat exchanger through bypass pipelines in a branch form, and heat of the other part of refrigerants is utilized for defrosting the outdoor heat exchanger; the temperature of the outdoor environment where the outdoor heat exchanger is located, and the temperature of a coil pipe of the outdoor heat exchanger are obtained; when the difference value between the outdoor environment temperature and the coil pipe temperature is larger than or equal to the preset temperature value, the rotation speed of an outdoor draught fan and the rotation speed in the heating mode are kept to be consistent; and when the difference value is smaller than the preset temperature difference value, running of the outdoor draught fan is stopped. The air conditioner device comprises the compressor, an indoor heat exchanger, a throttling device and the outdoor heat exchanger and further comprises the bypass pipelines, a temperature obtaining module and the outdoor draught fan, and the rotation speed of the outdoor draught fan can be adjusted in a controllable manner.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to an air conditioning device control method and the air conditioning device. Background technique [0002] Household air conditioners are currently an indispensable household appliance in ordinary families. They rely on the characteristics of cooling in summer to bring coolness and heating in winter to provide warmth, and are deeply loved by consumers. The air conditioner mainly relies on the four major components of the compressor, condenser, throttle, and evaporator to change the state of the refrigerant to achieve cooling and heating. [0003] Generally, when the air conditioner is running for heating when the outdoor ambient temperature is relatively low, the outdoor condenser will frost because the refrigerant temperature is lower than the air dew point temperature. With the operation of the air conditioner, the frost layer of the condenser is getting thicker and thicker, and th...
