Variable-air-volume whole-house healthy and comfortable air management system

Abstract

The invention relates to a variable-air-volume whole-house healthy and comfortable air management system. The variable-air-volume whole-house healthy and comfortable air management system comprises acontrol host, an air conditioning unit and a sensor unit. The air conditioning unit and the sensor unit are respectively in interactive connection with the control host. The air conditioning unit is respectively connected with an air supply air pipe and an air return air pipe and comprises a variable air volume system and an external auxiliary temperature adjusting device. A fan exchange device isdivided by a heat exchanger into an exhaust area, an air supply area, an air collection area and an air return area. The air supply area and the air return area are connected with an air mixing section, a cooling dehumidification section, a reheating section, an auxiliary heating section, a humidification section, an ultraviolet sterilization section and a composite purification section in sequence through a first electric valve and a second electric valve. A plurality of air problems existing at home are comprehensively treated, so that the health and comfort of air in the home environment are guaranteed. A plurality of air parameter processing capabilities are combined for unified computational planning, so that reasonable and coordinated operation of the system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air management, in particular to a whole-house healthy and comfortable air management system with variable air volume. Background technique [0002] Traditional household air conditioning (including air temperature adjustment, humidity adjustment, cleanliness adjustment, etc.) is mostly controlled by single data. For example, the traditional air conditioning system only controls the indoor temperature. Less than the user's requirements for comfort. Or a ventilation system that only has the ability to ventilate the room air. With the advancement of science and technology, models that can purify the incoming fresh air while exchanging air have also appeared in recent years. If the customer has high requirements for air quality, such as temperature, humidity, cleanliness, oxygen content, etc., which are required to meet healthy and comfortable standards, then only multiple systems can be installed at home ...

AI Technical Summary

Problems solved by technology

[0003] 1. Conventional civil air conditioning systems have relatively single functions and only have the ability to control certain single parameters, such as individual control of certain parameters such as oxygen content, PM2.5 purification, and humidity.

[0004] 2. The comprehensive solution is generally the superposition of multiple systems. If the early design calculation is improper, it will cause disordered parameter control in the later stage and increase energy waste.

[0005] 3. Lack of comprehensive coordination control system, the control is cumbersome and error-prone

[0006] 4. There is no indoor air parameter monitoring system, and it is impossible to effectively coordinate and control independent systems

[0007] 5. In some weather with high humidity but low temperature, such as the rainy season in the south, if the air conditioner is used to dehumidify, the room temperature will become colder, resulting in a decrease in comfort

If dehumidification is not carried out, the humidity is too high, the home is prone to mold, the human body feels uncomfortable, and affects the health of personnel
