Problems solved by technology
[0008] Under high temperature conditions in summer, the air conditioners in the office are all turned on, and over-adjustment will occur in many cases. For example, if the indoor temperature is set at 24°C, many female employees will feel a strong sense of cold; or under low temperature conditions in winter , the air conditioner is fully turned on, and the indoor temperature is set at 25°C. At this time, overheating occurs in some areas, which makes many employees feel a strong sense of heat, resulting in poor thermal comfort for users
[0009] In addition, the fresh air unit has been continuously turned on, which will increase the load on the air conditioning system and cause a lot of energy consumption.

The invention discloses a fresh air conditioning system which comprises a fresh air handling unit, an air conditioner indoor unit, a PMW acquisition unit and a control unit. The fresh air handling unit is provided with an air feeder and an air supply outlet; a movable air door is arranged at the air supply outlet; an indoor fan is arranged in the air conditioner indoor unit; the PMV acquisition unit is used for acquiring an indoor PMV; the control unit is configured to control the rotating speed of the air feeder and the size of the movable air door according to the PMV obtained in real time when the air conditioner indoor unit is not started, so that the PMV is made to be within a PMV target range; and when the air conditioner indoor unit is started, the rotating speed of the air feeder, the size of the movable air door and a gear of an indoor fan are controlled according to the PMV obtained in real time, so that the PMV is made to be within the PMV target range. According to the fresh air conditioning system provided by the invention, by means of the improvement effect of the airflow on the thermal comfort, the good thermal comfort of a user is intelligently achieved.
Description
technical field [0001] The invention relates to the technical field of fresh air air conditioning control, in particular to a fresh air air conditioning system. Background technique [0002] Fresh air conditioners include fresh air units and air conditioners. [0003] The fresh air unit is a high-efficiency and energy-saving heat recovery device. When it is working, when the indoor exhaust air and outdoor fresh air flow through the total heat exchange core in a positive crossing manner, due to the temperature difference and steam partial pressure of the airflow on both sides of the airflow partition plate Poor, when the two airflows pass through the partition plate, heat and mass transfer phenomenon occurs, causing a total heat exchange process. [0004] Air conditioners are used to adjust the temperature of the air in the room. [0005] At present, most of the thermal comfort air-conditioning systems adopt the control scheme in which the indoor temperature is the controll...
