Fresh Air Conditioning System

Abstract

The invention discloses a fresh air air conditioning system, comprising: a fresh air unit, which has a blower fan and an air supply port, and a movable damper is arranged at the air supply port; an air conditioner indoor unit, which is equipped with an indoor fan; a PMV acquisition unit, which is used to obtain indoor PMV; The control unit is configured to: when the indoor unit of the air conditioner is not started, control the rotation speed of the blower and the size of the movable damper according to the PMV obtained in real time, so that the PMV is within the PMV target range; PMV, control the speed of the blower, the size of the movable damper, and the gear of the indoor fan, so that the PMV is within the PMV target range. The present invention intelligently realizes good thermal comfort of users through the improvement effect of airflow on thermal comfort.

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. During operation, when the indoor exhaust air and the outdoor fresh air flow through the total heat exchange core in a positive cross manner, there is a temperature difference and steam partial pressure in the airflow on both sides of the airflow partition plate. When the two airflows pass through the partition plate, the phenomenon of heat and mass transfer occurs, resulting in a total heat exchange process. [0004] Air conditioners are used to regulate indoor air temperature. [0005] At present, in thermal comfort air conditioning systems, most of the control schemes in which the indoor temperature is the controlled parameter ...

AI Technical Summary

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.
