Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning units, and in particular to a combined type rotary heat recovery fresh air air-conditioning unit. Background Art

[0002] A typical air conditioning unit consists of a housing, which, from left to right, houses the air inlet, cooling, fan and mixing sections, heating and humidification sections, and outlet sections. Filter plates are installed at the inlet and outlet sections, at the front and rear ends of the housing, to filter the air as it circulates.

[0003] As global warming and environmental pollution become increasingly serious, people have an increasing demand for fresh air fans and air conditioners. As market demand changes, some places have to install both air conditioners and fresh air fans, which not only takes up a lot of space and requires many connecting lines, affecting the appearance, but also reduces safety.

[0004] After searching, a utility model patent with publication number CN111023331A was found, which specifically discloses a combined rotor heat recovery fresh air air-conditioning unit, including a shell, on which a return air inlet, an exhaust outlet, a fresh air inlet and an air supply inlet are provided. A group of functional sections that cooperate with each other are provided in the shell, including: a fresh air filter section, a high-efficiency rotor section, a cooling and heating surface cold section, a humidifier section, a silencer section, an air supply section, an exhaust filter section, an exhaust section, and a bypass air valve is provided between the exhaust filter section and the cooling and heating surface cold section; the functional sections cooperate to form a fresh air heat recovery functional group, a fresh air heat recovery air-conditioning functional group and an internal circulation functional group; through the high-efficiency rotor, the heat of the indoor and outdoor air is heat exchanged to avoid excessive heat loss of the discharged indoor air, thereby increasing the heat of the introduced fresh air and achieving energy-saving effect.

[0005] The aforementioned patent utilizes a high-efficiency rotor to exchange heat between indoor and outdoor air. However, during use, the fresh air unit requires the installation of a filter valve core and a heating plate in the air inlet section. The filter valve core deteriorates after long-term use, necessitating prompt cleaning of the filter valve core. Failure to do so can easily cause air impurities to adhere to the heating plate, causing a short circuit and potentially posing a safety hazard. Therefore, it is essential to propose a combined rotor heat recovery fresh air air conditioning unit to address this issue. Utility Model Content
