Abstract

The invention discloses an automatic regulation and control antifreezing system for an air conditioning unit. The automatic regulation and control antifreezing system comprises an antifreezing device arranged outside a box body, a temperature sensor, a relay and a control box. A signal processing circuit is arranged in the control box, and the signal processing circuit comprises an audion. The base electrode of the audion is electrically connected with the temperature sensor through a resistor R7 and a resistor R6, the resistor R7 and the resistor R6 are in series connection, the collector electrode of the audion is connected to the ground, and the emitting electrode of the audion is electrically connected with the positive electrode of a diode D2 and a coil ground terminal of the relay respectively. The negative electrode of the diode D2 and a coil power source terminal of the relay are both connected with a 12 V voltage, and meanwhile a normally-opened contact of the relay is electrically connected with a power source of the air conditioning unit. The automatic regulation and control antifreezing system for the air conditioning unit has the function for automatically regulating and controlling operation of the antifreezing device, so that a heat exchange hot coil can be prevented from being cracked due to frost, and the purpose of energy saving and environmental protection is achieved as well.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an automatic regulation antifreeze system for an air conditioner unit. Background technique [0002] At present, the air conditioning unit is equipped with an electric intake valve, a primary filter, a medium filter, a heat exchanger, a blower, and a supply outlet in order according to the direction of the fresh air. In every winter, especially in the area north of the Yangtze River, the heat exchange coils of air conditioning units often freeze and crack due to various reasons, causing non-negligible losses to users, ranging from replacing equipment to affecting production. [0003] There are generally two situations in which the heat exchange coil appears to be frozen and cracked. Freeze cracking during shutdown, that is, when the air conditioning unit is out of use, because the water in the heat exchange coil is not drained, when the air around the heat exchange coil...
