Abstract
The invention provides an environment-friendly all-in-one machine structure and an air quality and air volume control method thereof, relates to the field of air conditioners, and provides a set of control methods for temperature, humidity, oxygen content, PM2.5 and VOC gas concentration.
Description
Technical Field
The application relates to the field of air conditioners, in particular to an environment-control all-in-one machine structure and an air quality and air quantity control method thereof.
Background
Along with the improvement of the living standard of people and the improvement of the knowledge-level of the harm caused by air pollution of people, people put forward higher and higher requirements on the air quality of the living environment. In addition to the requirement on the temperature comfort of the air, higher requirements are put on the humidity, the oxygen content, the PM2.5 concentration and the VOC (volatile organic gas) concentration of the air. The traditional air conditioner can only control the temperature of air through refrigeration and heating, reduces the humidity of the air through refrigeration and dehumidification, and cannot control the oxygen content, the PM2.5 concentration and the VOC concentration at the same time. And traditional new fan can only carry out oxygen content control through introducing the new trend, carries out PM2.5 and VOC control through filter equipment, and can not compromise the atmospheric control of air.
The existing environment-control all-in-one machine generally adopts a mode of air pipe connection, and because of different engineering projects, the specification, the length and the connection mode of on-site air pipes can be different, so that the resistance of the air pipes often deviates from the design value of a manufacturer, and the performance of a unit cannot be fully exerted or even cannot be normally operated. The environment-control all-in-one machine adopts a fan which is an alternating current fan or a direct current fan. The alternating current fan is poor in adjusting capacity, and when the resistance of the engineering air pipe deviates from the design of the unit, the resistance cannot be adjusted, so that the air quantity deviates from the design value, and the unit effect is reduced. The direct current fan is adopted, and the conventional manufacturer generally adjusts the revolution manually according to the condition of an engineering field. This approach is highly demanding for the commissioning personnel and inefficient as it requires adjustment at each site. In addition, when the traditional environment-controlled all-in-one machine is in a wind mixing mode, namely a circulating air port and a fresh air port are simultaneously introduced with wind, the on-site adjustment difficulty is higher.
The existing environmental control all-in-one machine fresh air control is simpler, the fresh air is directly sent into the heat exchange filter element through the switch of the fan or the fresh air valve and is subjected to heat exchange with the air exhaust, if the temperature of the fresh air is favorable for the indoor temperature, the fresh air and the air exhaust are still subjected to unfavorable heat exchange in the control mode, and energy is not saved. In addition to the control to new trend temperature, traditional scheme adopts the supplementary electrical heating control of one-level, and this kind of control preheats at the big environment of new trend temperature variation range, can not be fine. If new trend wind-powered electricity generation electrical heating undersize, then the new trend preheating is not enough when the new trend temperature is low and leads to the travelling comfort poor, if new trend electrical heating is too big, when the new trend temperature is higher, then excessively preheat and lead to the energy consumption high.
