Combined air conditioner and control method thereof

Abstract

The invention relates to the technical field of an air conditioner, and in particular relates to a combined air conditioner and a control method thereof. The invention aims to solve the problem that the combined air conditioner cannot monitor and control exhaust air. For the purpose, the combined air conditioner comprises a box body, a first air returning segment, an efficient filtering segment, areturn air duct, an air quality detection device and a control device, wherein an air inlet segment and an air outlet segment are respectively arranged at the two ends of the box body; an air inlet is formed in the air inlet segment, an air outlet is formed in the air outlet segment, and a first valve body which can be opened and closed is arranged at the air outlet; the first air returning segment and the efficient filtering segment are arranged between the air inlet segment and the air outlet segment, and an efficient filtering component is arranged in the efficient filtering segment; the two ends of the return air duct respectively communicate with the first air returning segment and the air outlet segment, and a second valve body is arranged at the communicating position of the returnair duct and the first air returning segment; the air quality detection device is arranged in the air outlet segment; and the control device is respectively connected with the air quality detection device, the first valve body and the second valve body. The combined air conditioner can monitor and control the quality of the exhaust air and ensure the quality of the exhaust air.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a combined air conditioner and a control method thereof. Background technique [0002] The combined air conditioner is a terminal device of the central air conditioning system, which can realize the functions of filtering, cooling, supplying air, purifying and sterilizing the air. [0003] Existing combined air conditioners are generally equipped with air filter devices and sterilization purification devices in order to reduce particulate matter, dust mites, bacteria and other pollutants that have an impact on human health in the air during air supply. Combined air conditioners have higher requirements for air quality in medical applications. Although the current combined air conditioners are equipped with the above-mentioned filter devices and sterilization and purification devices, they can also achieve corresponding functions, but they lack the airflow discharged from...
