Fresh air air-conditioning system and control method

Abstract

The invention discloses a fresh air air-conditioning system and a control method, and belongs to the fresh air air-conditioning technical field. The control method comprises the following steps that work modes are selected according to indoor air temperature and indoor air humidity and comprise a fresh air work mode, an air-conditioning work mode and a manual mode; in the air-conditioning work mode, the fresh air air-conditioning system is configured to only suck indoor air, and the indoor air temperature and humidity are independently adjusted and controlled; and in the fresh air work mode, the fresh air air-conditioning system is configured to only suck outdoor air and filter the sucked outdoor air, and different fresh air work sub-modes are selected to be executed. The fresh air air-conditioning system comprises a fresh air module and an air-conditioning module, and the fresh air module and the air-conditioning module are in sealed communication. By means of the fresh air air-conditioning system and the control method, the temperature and humidity of indoor air can be rapidly adjusted, the advantages of low noise and the large fresh air inflow quantity are achieved, and the advantages of the high indoor air replacement rate and low energy consumption and economic cost are also achieved.

Description

technical field [0001] The invention belongs to the technical field of fresh air air conditioning, and in particular relates to a fresh air air conditioning system and a control method. Background technique [0002] The air conditioner is mainly composed of compressors, condensers, evaporators, fans, throttle valves and other major components. Each major component is connected in series with copper pipes to form a circuit. At present, the mainstream air conditioner products in the market are in the form of split air conditioners, which are structurally divided into two parts: the indoor unit and the outdoor unit of the air conditioner. The evaporator is installed in the indoor unit, and the condenser is installed in the outdoor unit. Under the action of the circulating flow in the air conditioning system circuit, the heat exchange between the outdoor unit and the indoor unit is carried out, so as to achieve the purpose of controlling the air temperature in the room; in order...

Problems solved by technology

This not only leads to excessive loss of energy, indoor space and economic costs, but also the matching control between the air conditioner and the fresh air fan is very complicated. If the air conditioner and the fresh air fan cannot work in harmony, the air conditioner will continue to stir and circulate the indoor air. It will make it difficult for the fresh air inhaled by the fresh fan to form a slight positive pressure effect and an efficient airflow organization effect indoors, and instead cause the efficiency of the indoor fresh air to replace the old air is not high
