Problems solved by technology
In the existing technology, most of the air conditioners based on micro-positive pressure control are controlled by differential pressure switches. The detection accuracy of the differential pressure switch is low, and they can only be controlled according to the fixed differential pressure. Two states, unable to achieve precise control according to the actual needs of the site
The current air conditioners using micro positive pressure control mostly use fresh air fans to introduce fresh air, adding fresh air fans leads to complex control, unstable fresh air volume control, and cannot achieve the stability of micro positive pressure; air conditioners often use complex mechanisms such as air ducts To introduce fresh air, resulting in a relatively large volume, and generally use one-way fresh air to increase the pressure, which cannot effectively relieve pressure

The invention discloses a micro-positive-pressure cabinet air conditioner which comprises a cabinet, a condenser, a compressor, an outdoor fan, an evaporator, an indoor fan, a fresh air valve device and a pressure relief device. The cabinet comprises an indoor cavity and an outdoor cavity. The condenser, the compressor and the outdoor fan are arranged in the outdoor cavity, and the evaporator, theindoor fan, the fresh air valve device and the pressure relief device are arranged in the indoor cavity. The micro-positive-pressure cabinet air conditioner further comprises a controller, a micro-positive-pressure sensor, a temperature sensor and a humidity sensor which are arranged in the indoor cavity. The controller is electrically connected with the fresh air valve device, the pressure relief device, the micro-positive-pressure sensor, the temperature sensor and the humidity sensor. According to the micro-positive-pressure cabinet air conditioner, design is reasonable, the structure is simple, the pressure can be adjusted bidirectionally, thus the applied cabinet environment forms the stable micro positive pressure, and the good using and popularizing value is achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a micro positive pressure cabinet air conditioner. Background technique [0002] At present, the application fields of air conditioners are becoming wider and wider. In addition to high-power air conditioners used in large-scale spaces, some small airtight spaces that need to maintain a specific temperature, such as outdoor communication cabinets, wireless outdoor cabinet base stations, battery cabinets, electrical control boxes, Corresponding air conditioners are also required for communication equipment, collection display cabinets, etc. This kind of environment often requires air conditioners to maintain accurate pressure, temperature and humidity. In the existing technology, most of the air conditioners based on micro-positive pressure control are controlled by differential pressure switches. The detection accuracy of the differential pressure switch is l...
