とを特徴とする除霜制御装置。In a heat pump air conditioner that defrosts using a reverse cycle defrosting method, a bypass circuit is installed that connects the high pressure side and the low pressure side via an on-off valve, and the compressor is stopped when defrosting operation starts, and the high pressure side The on-off valve is opened in order to equalize the pressure between the low pressure side and the low pressure side, and after a predetermined time t1, the four-way valve is switched to a reverse cycle, and then the four-way valve is switched to a reverse cycle for a predetermined time t2.
1. A defrosting control device characterized in that, after a period of time has elapsed, the on-off valve is closed and a compressor is restarted to perform reverse cycle defrosting.
