Description

Technical Field

[0001] The utility model relates to the technical field of fresh air air conditioners, in particular to an air pressure regulating device for fresh air air conditioners. Background Art

[0002] The fresh air system of air conditioner is one of the three major air circulation systems of air conditioner, namely indoor air circulation system, outdoor air circulation system and fresh air system. The main function of fresh air system is to realize the circulation and ventilation between room air and outdoor air, and also to purify the air. The turbid air in the room is discharged to the outside through the fresh air system pipe to form the pressure difference between indoor and outdoor air, complete the air exchange between indoor and outdoor, and refresh the air.

[0003] The patent with publication number CN 212274227 U discloses a multi-compressor pressure-stabilizing fresh air air conditioning system, which includes a condensing mechanism, one side of the condensing mechanism is connected to a heat exchanger, and the side of the heat exchanger away from the condensing mechanism is connected to a compression mechanism, wherein the side of the compression mechanism away from the heat exchanger is connected to the other side of the condensing mechanism. The device detects the air pressure in the air inlet pipe through a barometer, and when the pressure is greater than 1.8MPa, the air valve is closed, and when the pressure is lower than 1.5MPa, the air valve is opened to keep the system pressure within this range. When the air valve is opened, part of the air can be prevented from passing through the heat exchanger, that is, by reducing the heat exchanger. The ventilation volume of the heat exchanger is used to regulate the pressure in the system. However, the device controls the opening and closing of the air valve to adjust the ventilation volume entering the heat exchanger to regulate the system pressure. However, in the process of introducing air from the air inlet pipe into the heat exchanger, dust and impurities contained in the air can easily cover the air distribution plate directly and block the ventilation holes, which can easily cause the air to be unable to be evenly distributed in the heat exchanger using the air distribution plate, thereby affecting the regulation of the system air pressure. For this reason, an air pressure regulating device for fresh air air conditioning is proposed to solve the problem that the existing air pressure regulating device is easily blocked by dust and affects the air pressure regulation.
