Air conditioning method and air conditioning device through large-flow mixed air supply

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...

Problems solved by technology

[0003] The present invention provides an air-conditioning method and an air-conditioning device for large-flow mixed air supply, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the existing indoor air-conditioning problems. When the air supply temperature of the air conditioner is low, the human body will have an uncomfortable feeling of blowing cold wind, and when the air supply temperature is high, the cooling effect of the air conditioner will not be obvious.
