Embodiment 1

[0021] As shown in accompanying drawings 1, 2, 3, and 4, the air-conditioning method of this large-flow mixed air supply is carried out according to the following steps: the airflow blown out in the air supply port 3 of the air conditioner unit forms the unit air supply, and the air supply area between the air conditioner unit The external airflow forms return air, and the mixing fan 1 sucks the air supply and return air of the unit through the mixing fan air inlet 4 and sends it out through the mixing fan air outlet 5. The present invention introduces the return air through the mixing fan 1, and then increases the flow rate and speed of the air supply as the entry point. Under certain air supply conditions, the thermal comfort of the human body can be improved, making it possible to apply the mode of higher air supply temperature. ; The air-conditioning unit may be a traditional air-conditioning unit or an evaporative cooling air-conditioning unit.

Embodiment 2

[0023] As shown in accompanying drawings 1, 2, 3, and 4, the air-conditioning device in the above-mentioned embodiment 1 includes an air-conditioning unit and a mixing fan 1. Fan 1, the mixing fan 1 has a mixing fan air inlet 4 and a mixing fan outlet 5, and the air supply port 3 communicates with the mixing fan air inlet 4.

[0024] According to actual needs, the above-mentioned embodiment 2 can be further optimized or / and improved:

Embodiment 3

[0026] As shown in Figure 1, the difference from the above embodiment is that the mixing fan 1 of embodiment 3 is placed near the air outlet 3 (that is, the mixing fan 1 and the air conditioning unit are separated from each other); A return air inlet 6 capable of inhaling return air is formed between the tuyere 4 and the air conditioning unit, and the air supply port 3 and the return air inlet 6 of the air conditioning unit communicate with the air inlet 4 of the mixing fan at the same time.

Abstract

The invention relates to the technical field of heat ventilation and air conditioning and provides an air conditioning method and air conditioning device through large-flow mixed air supply. The air conditioning method comprises the following steps that airflow which is blown out from the air supply port of an air conditioning unit forms unit supply air, airflow outside the air supply area of the air conditioning unit forms return air, and a mixed air fan sucks in the unit supply air and the return air through a mixed air fan air inlet and blows out the mixed air through a mixed air fan air outlet. The air conditioning method and the air conditioning device through large-flow mixed air supply have the technical effects that the thermal comfort of human bodies can be enabled to be greater by adding the mixed air fan and properly improving air supply flow and air supply speed; and under different working conditions, by adjusting the mixing ratio of the supply air to the return air, the energy saving effect is better during operation, the application under the working conditions of higher air supply temperature becomes possible, the outdoor fresh air can be effectively introduced into a room, and an inlet, an outlet and flow passage for indoor and outdoor airflow interaction are formed.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air-conditioning, and relates to an air-conditioning method and an air-conditioning device for large-flow mixed air supply. Background technique [0002] The thermal comfort of the human body in an indoor room is closely related to the combined effects of various factors. Theoretical studies have shown that the indoor return air temperature, the relative humidity of the indoor return air, the air velocity near the human body, the temperature of the inner surface of the enclosure structure and the surface of other objects , the temperature of the human body, heat dissipation and body temperature regulation, and the thermal insulation performance and air permeability of clothes are all related to it. Among the above factors, the air velocity near the indoor human body is one of the main factors affecting the heat dissipation by convection and evaporation of the human body. When the...
