Description

Technical Field

[0001] This utility model relates to the field of fresh air conditioning technology, and in particular to a constant temperature and humidity fresh air integrated unit. Background Technology

[0002] Currently, most fresh air conditioning systems are equipped with two functions: outdoor fresh air supply and indoor air circulation, which complement each other. However, in actual operation, if the flow of people indoors is small and the indoor air quality remains stable, the fresh air function is usually turned off or turned on intermittently in order to reduce energy consumption.

[0003] The technical problem encountered in existing technologies is that the fresh air operation path of such fresh air modules is complex and cannot be matched with the operation path of indoor recirculated air. Both often operate independently within units close to the room, leading to increased operating costs for the fresh air function unit. Therefore, to adapt to this type of operation requiring relatively small amounts of outdoor fresh air replenishment while reducing equipment operating costs, a fresh air module primarily for indoor recirculation is needed. However, the basic functions of existing fresh air modules tend to focus on fresh air replenishment.

[0004] Considering the actual situation of existing technologies, it is very necessary to design a constant temperature and humidity fresh air unit, whose main function is to circulate indoor airflow, while reducing the operating cost of the equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a constant temperature and humidity fresh air unit, which adopts a dual surface cooler structure and can be directly connected to an external hot and cold water system or an air source heat pump to achieve indoor air circulation and constant temperature and humidity regulation.

[0006] As described above, a constant temperature and humidity fresh air unit includes a housing. The outer wall of the housing has an indoor circulation inlet, an outdoor air inlet, and an indoor return air inlet. The indoor circulation inlet and the outdoor air inlet are located on the same side and follow the same operating path. Inside the housing are a filter module, a fan compartment, a surface cooling module, and a humidification compartment. The filter module is located behind the indoor circulation inlet and the outdoor air inlet, and contains a filter element. Behind the filter module is the fan compartment, which contains a fan. Behind the fan compartment is the surface cooling module, which contains at least two sets of surface coolers operating synchronously. Behind the surface cooling module is the humidification compartment, which contains a wet film module. A humidification pump and a control valve are installed in conjunction with the wet film module. The control valve is connected to an external water supply connector. A water collection tray is located at the bottom of the wet film module, and a pipe on the water collection tray connects to an external drain pump. The drain pump has an external drain connector. The rear of the humidification compartment is connected to an indoor air outlet.

[0007] The indoor return air vents are provided with at least two, and multiple indoor return air vents can be used to achieve air supply to multiple indoor areas.

[0008] The two sets of surface coolers are equipped with a cold source inlet and a cold source outlet, and the two sets of surface coolers are connected in series through pipelines.

[0009] The side of the housing is equipped with maintenance baffles corresponding to the filter module, fan compartment, and humidification compartment, which enable quick-release protection of the interior.

[0010] The filter module has a filter screen on the front side of the filter element, which enables primary filtration within the filter module.

[0011] This utility model has the following beneficial effects: Through the above structural design, the outer wall of the housing is equipped with an indoor circulation port, an outdoor air inlet, and an indoor air outlet; the housing contains a filter module, a fan compartment, a surface cooling module, and a humidification chamber. The filter module contains a filter element; the rear of the fan compartment is the surface cooling module, which contains at least two sets of surface coolers operating synchronously; the rear of the surface cooling module is the wet film module, and the rear of the humidification chamber is connected to the indoor air outlet.
