Ventilation and air conditioning system

Abstract

The invention provides a ventilation air conditioning system. A reversing mechanism which enables indoor air to flow in when refreshing the indoor air and enables the outdoor air to flow in when not refreshing the indoor air, and a ventilating fan which is used for guiding airflow to flow to an outdoor electronic control box are arranged on an outdoor machine, and the problems of large operating noise and inconvenience in installation of the ventilating fan can be solved when the ventilating fan and the outdoor machine are integrated; simultaneously, when the indoor air is refreshed, the air extracted from a room is not discharged directly but discharged to the outdoor electronic control box for cooling, the heat dissipation condition of the outdoor electronic control box is reinforced, the reliability of the outdoor electronic control box is improved or the operation frequency of a compressor under the operating condition with high temperature is provided, and therefore the effect of heat transfer is improved; under the condition of not refreshing the indoor air, the air with the environment temperature is extracted outdoors by the ventilating fan to be used for cooling the outdoor electronic control box, and the reliability of the outdoor electronic control box and the operation frequency of the compressor under the condition of high temperature can also be improved.

Description

technical field [0001] The invention belongs to the field of air conditioning, and in particular relates to a ventilation air conditioning system. Background technique [0002] With the continuous improvement of people's life, the simple cooling and heating functions of the air-conditioning system provided by the prior art can no longer meet people's needs, and people's demand for the health function of the air-conditioning system is becoming stronger and stronger. In an air-conditioned room, the biggest health killer is poor air circulation. There are many air-conditioning systems with ventilation function on the market. The main principles are: 1. By blowing fresh air into the room, a positive pressure is formed, so that the dirty air in the room is discharged from the cracks in the door and window, thereby Realize fresh air exchange; 2. By sucking away the turbid air in the room, a negative pressure is formed in the room, so that the outdoor fresh air is sucked in from t...

Problems solved by technology

[0003] The object of the present invention is to provide a ventilation fan and an outdoor unit that are integrated and indoor air is introduced to cool the outdoor electric control box when the indoor air is replaced, and outdoor air is introduced to cool the outdoor electric control box when the indoor air is not replaced. The ventilation air conditioning system is designed to solve the problems of working noise and inconvenient installation when the existing air conditioning system has the function of changing indoor air
