Detailed Description

The present invention will be described in further detail below.

As shown in fig. 1 to 5, an air conditioner defrosting device applied to a condenser 3 of an outdoor unit 5 of an air conditioner includes a plurality of capillary tubes 11, the capillary tubes 11 are respectively inserted into the condenser 3, each capillary tube 11 is provided with an open end and a closed end, the closed end is disposed in the condenser 3, the open end is communicated with an exhaust pipe of the outdoor unit 5, and a switch is disposed on a pipeline connecting the capillary tube 11 and the exhaust pipe of the outdoor unit 5.

Specifically, when the condenser 3 of the outdoor unit 5 starts to frost, the switch on the communication pipeline between the capillary tube 11 and the exhaust pipe of the outdoor unit 5 is opened, and the high-temperature refrigerant gas compressed in the exhaust pipe of the outdoor unit 5 enters the capillary tube 11 through the open end of the capillary tube 11. Because the plurality of capillary tubes 11 are respectively arranged in the condenser 3 in a penetrating way, the capillary tubes 11 introduced with high-temperature refrigerant gas can quickly raise the temperature of the condenser 3, thereby achieving the purpose of quickly defrosting.

The closed end of the capillary tube 11 prevents the high-temperature refrigerant entering the capillary tube 11 from losing during defrosting, so that the hot air in the capillary tube 11 and the hot air in the exhaust pipe are always in a temperature balance state, and the defrosting capability is prevented from being reduced due to the temperature reduction of the hot air in the capillary tube 11, and the defrosting effect is prevented from being influenced.

After defrosting is finished, the switch on the communication pipeline between the capillary tube 11 and the exhaust pipe of the outdoor unit 5 can be closed, so that part of the refrigerant introduced with defrosting can be returned to the heating system again.

In conclusion, the defrosting device can be used for quickly defrosting the condenser 3, the heating capacity of the air conditioner is not affected in the defrosting process, heating can be stopped during defrosting, and user experience is good.

The capillary tubes 11 and the outdoor unit 5 are communicated with each other through a main air inlet tube 12, the open ends of the capillary tubes 11 are respectively communicated with one end of the main air inlet tube 12, the other end of the main air inlet tube 12 is communicated with the exhaust pipe, and the switch is arranged on the main air inlet tube 12. The high-temperature refrigerant gas of the exhaust pipe can be more conveniently distributed to the capillary tubes 11 through the total inlet pipe 12.

Each capillary tube 11 is arranged horizontally.

Specifically, the capillary tube 11 is horizontally placed in the condenser 3 and is placed between the upper copper tube and the lower copper tube, so that the assembly and the uniform defrosting are facilitated, and meanwhile, after the defrosting is completed and the switch is turned off, high-temperature refrigerant gas in the capillary tube 11 can flow back without being retained in the capillary tube 11 to cause the total amount of the refrigerant of the whole system to be lower.

The condenser 3 is provided with a plurality of horizontal mounting holes 31, and a plurality of capillary tubes 11 are uniformly distributed in the mounting holes 31 of the condenser 3, so that all parts of the condenser 3 are uniformly heated when defrosting, and a better defrosting effect is achieved.

Preferably, the switch is a solenoid valve 2. The electromagnetic valve 2 is connected with a control device of the air conditioner, can realize automatic conduction or closing of the main air inlet pipe 12, and is favorable for realizing automatic defrosting.

The air conditioner is provided with a control device and a condenser 3 and comprises an air conditioner defrosting device, wherein the air conditioner defrosting device is installed on the condenser 3, and a switch of the air conditioner defrosting device is connected with the control device of the air conditioner.

Specifically, the air conditioner is provided with an indoor unit 4 and an outdoor unit 5. When the condenser 3 of the outdoor unit 5 is frosted to cause insufficient heating capacity, the air conditioner control device detects that the heating capacity is reduced and defrosting is needed, and then the switch of the electromagnetic valve 2 is controlled to be opened. At this time, the high temperature refrigerant gas compressed in the exhaust pipe of the outdoor unit 5 enters the condenser 3 of the outdoor unit 5 through the capillary tube 11, so that the temperature of the condenser 3 is rapidly raised, thereby achieving the purpose of rapid defrosting. After defrosting of the condenser 3 is finished, heating capacity is increased, after the control device detects that the heating capacity is increased, the switch of the electromagnetic valve 2 is controlled to be closed, high-temperature refrigerant gas does not enter the capillary tube of the condenser 3 of the outdoor unit 5 any more, and meanwhile, part of refrigerant introduced into defrosting flows back to the heating system again.

The air conditioner provided by the embodiment of the invention can be used for defrosting after the condenser 3 of the outdoor unit 5 is frosted, heating can be stopped during defrosting, and the user experience is good.
