Fresh-air air conditioner all-in-one machine and air conditioning system using all-in-one machine

Abstract

The invention relates to a fresh-air air conditioner all-in-one machine and an air conditioning system using the all-in-one machine. The fresh-air air conditioner all-in-one machine uses the characteristic of intake on two axial sides and exhaust on radial side of a double-suction centrifugal fan for sucking in outdoor fresh air and indoor return air from two sides of the double-suction centrifugal fan for heat exchange on a heat exchange part; in a mixed exhaust port, the heat-exchanged indoor return air and the heat-exchanged outdoor fresh air realize mixing; on the one hand, the treatment mode guarantees heat exchange air currents, exhausted from the fresh-air air conditioner all-in-one machine, to include one part of fresh air, and the part of fresh air aerates, humidifies and cleans the indoor air; and on the other hand, through the mode of mixing the fresh air with the return air, according to the characteristic of low power needed by heat exchange of the return air, the heat-exchanged return air is used for compensating the temperature change of the fresh air; and the air conditioning system and the fresh-air air conditioner all-in-one machine have the advantages of energy conservation, emission reduction and capability of keeping comfortable indoor environment.

Description

technical field [0001] The invention relates to an integrated fresh air air conditioner and an air treatment system using the integrated machine, and relates to the fields of fresh air systems and air conditioning systems. Background technique [0002] At present, along with the increase of people's material living needs, air conditioners are generally installed in homes or offices. Generally, air conditioners are composed of evaporators, condensers, compressors, etc., which can cool or heat indoor air and create a suitable indoor environment for users. Air conditioners are classified in terms of distribution form, and can be divided into split type and integrated type. Split type and integrated type have the same function. Specifically, the split-type air conditioner is to install an indoor unit with cooling / heating function indoors, and an outdoor unit with heat release / cooling and compressor outdoors, and connect the outdoor unit and the indoor unit through refrigerant ...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned air-conditioning system, the cooling / heating object of the air-conditioning system is still the indoor return air circulation airflow, so the airflow discharged from the air-conditioning system still has no outdoor fresh air to fill in, and the indoor air still has the problem of hypoxia, causing users to Discomfort such as dizziness, retching, and weakness in hands and feet occurs during use

[0005] In addition, although there are air-conditioning systems in the prior art that directly cool the fresh air and introduce it into the room, such as the double-sided heat exchange type split air conditioner disclosed in CN1177710A, this method of directly introducing the fresh air into the room through the heat exchanger has a degree of comfort. Insufficient and high energy consumption, the former is mainly because the indoor environment temperature of the user is not suitable during the cooling / heating cycle from the start of the air conditioning system to the predetermined temperature, so the user experience is poor; the latter is mainly Affected by the large temperature difference between indoor and outdoor, in order to quickly cool the outdoor air flowing through the heat exchanger to the required temperature, the compressor needs higher power, which leads to an increase in energy consumption of the entire air conditioning system
