Problems solved by technology
Therefore, the heating work cannot be performed at the same time as the defrosting work
In addition, cold air is sent into the interior of the room from the outdoor heat exchanger, therefore, the temperature of the interior of the room is lowered, which causes inconvenience to the user
In addition, the outdoor temperature is inferred from the difference between the temperature of the indoor heat exchanger and the temperature inside the room, so it is difficult to accurately obtain the timing of defrosting work, and it is difficult to perform defrosting work smoothly

A heat pump air conditioner with an improved defrosting structure and a defrosting method thereof. When frost does not excessively accumulate on the outdoor heat exchanger piping network, the solenoid valve is controlled to allow the warm refrigerant from the compressor to intermittently pass through the second piping, the heat-discharging piping and the third piping. When the air conditioner works in the heating mode, the amount of frost accumulated on the outdoor heat exchanger is deduced from the temperature of the outdoor heat exchanger pipe network, and then the defrosting operation is performed based on the temperature of the outdoor heat exchanger pipe network. Thereby, based on the amount of frost accumulated on the outdoor heat exchanger, the frost accumulated on the outdoor heat exchanger is quickly removed, reducing the time that the air conditioner is not operating, thereby providing more comfortable and pleasant heating to the user Function.
Description
technical field [0001] The present invention relates to a heat pump type air conditioner, and more particularly, to a heat pump type air conditioner having an improved defrosting structure capable of removing heat accumulated in the outdoor space while minimizing user's inconvenience when performing a heating operation under low temperature outdoor air. Frost on the exchanger. Meanwhile, the present invention relates to a defrosting method for such a heat pump type air conditioner. Background technique [0002] figure 1 It is a schematic diagram showing the structure of a conventional heat pump type air conditioner. like figure 1 As shown, the existing heat pump air conditioner includes: a compressor 11, which is used to compress and circulate the refrigerant; a four-way valve 12, which is used to change the flow direction of the refrigerant so that the refrigerant can flow forward or reverse; The heat exchanger 13 is configured so that it can be used as a condenser when...
