Air conditioner and quick startup control method thereof

Abstract

The invention discloses a quick startup control method of an air conditioner. The air conditioner includes an air conditioner main body and a remote controller. The control method includes the following steps: 1) during a refrigeration operation, the air conditioner receiving a stop instruction sent by the remote controller and then entering into a standby state, the opening of an adjustable throttling member being a maximum value, high pressure refrigerant in an outdoor heat exchanger fast flowing to an indoor heat exchanger through the adjustable throttling member; 2) during a heating operation, the air conditioner receiving the stop instruction sent by the remote controller and then entering into the standby state, the opening of the adjustable throttling member being the maximum value, the high pressure refrigerant in the indoor heat exchanger fast flowing to the outdoor heat exchanger through the adjustable throttling member; and 3) the air conditioner receiving a starting instruction sent by the remote controller and restarting. An electronic expansion valve of the invention can balance a system pressure in 15 seconds, and compared with the pressure balancing time of about 3 minutes of the prior art, the time is greatly shortened, so that the air conditioner can be quickly restarted, the comfort of the air conditioner can be effectively improved and the service life of the air conditioner can be effectively prolonged.

Description

technical field [0001] The invention relates to an air conditioner and a quick restart control method thereof. Background technique [0002] During the operation of the heat pump air conditioner, after receiving the stop command, the control component directly cuts off the power to the compressor, fan and other components. Due to the throttling element between the outdoor heat exchanger and the indoor heat exchanger, it is difficult to balance the pressure in the outdoor heat exchanger and the pressure of the indoor heat exchanger in a short time. If it is turned on immediately, due to the excessive pressure, the starting current will be too large or the compressor will fail to start, which cannot guarantee the safe and reliable operation of the air conditioner. At present, some manufacturers generally use a delay method to solve the above problems. Generally, the restart after a shutdown requires a delay of 3 minutes before it can be started. But still there are following...

AI Technical Summary

Problems solved by technology

[0003] 1. When the inner diameter of the capillary is small or long, the system pressure balance takes a long time, and the standby time often exceeds 3 minutes. When starting the compressor under such circumstances, there may still be a large starting current or compressor startup In case of failure, it will adversely affect the reliability and service life of the air conditioner

[0004] 2. The air conditioner cannot start quickly. If the user accidentally presses the power button one more time, the air conditioner must wait for 3 minutes before the air conditioner can start, which brings inconvenience to the user.
