Abstract

The invention relates to an air conditioning system. The air conditioning system comprises a refrigerating circulation component, a total heat exchange core body, a return air flow path component anda fresh air flow path component, wherein the refrigerating circulation component comprises a compressor, a first heat exchanger and a second heat exchanger that are in loop connection; the return airflow path component is used for conveying part of indoor air to the total heat exchange core body for heat exchange, and mixing the part of heat exchanged indoor air with the rest indoor air in the return air flow path component, and mixed indoor air is discharged outdoors after exchanging heat with the first heat exchanger; and the fresh air flow path component is used for conveying part of outdoor air to the total heat exchange core body for heat exchange, and mixing part of heat exchanged outdoor air with the rest outdoor air in the fresh air flow path component, and mixed outdoor air is delivered indoors after exchanging heat with the second heat exchanger. Thus, exhaust air, i.e., the discharged indoor air, can be increased in temperature while fresh air, i.e., the conveyed outdoor air, is heated, thereby realizing frostless operation of the first heat exchanger during low-temperature heating; the indoor temperature is small in fluctuation, and comfort is high. The invention further provides a control method of the air conditioning system.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an air-conditioning system and a control method thereof. Background technique [0002] Fresh air air conditioners usually use a total heat exchange core to allow fresh air and exhaust air to perform full heat exchange in the core, recover exhaust air cooling (summer) and heat (winter), reduce fresh air load, and improve system energy efficiency. At present, part of the total heat exchange core is made of graphene modified film to solve the problem of ice blockage of the total heat exchange core at low temperature, so that the working condition of the total heat exchange fresh air air conditioner can be as low as -25°C. However, the outlet temperature of the exhaust air after passing through the total heat exchange core is close to the temperature of the outdoor fresh air. When the temperature of the outdoor fresh air is lower than 0°C, after the low-temperature...
