Cabinet air conditionerTechnical Field
The utility model relates to the technical field of air conditioners, in particular to a cabinet air conditioner.
Background
The air supply port and the air return port of the traditional air conditioner are relatively fixed in structure, and air can only enter the fixed air duct system through the designated air inlet to complete the circulation of a fixed wind direction path, so that the heating/refrigerating purpose is achieved. The fixed wind direction path has longer time for heating/cooling and consumes more energy. However, the user's requirement for the air conditioner is that the indoor temperature can reach the designated temperature quickly after the power-on, so that the conventional air conditioner is not optimal in terms of user experience and energy saving.
Taking a cabinet air conditioner with upper, lower and upper back air sending as an example, the air supply opening is higher in the upper position of the air conditioner, when refrigerating and cold air sending in summer, the air enters the side edge of the shell through the lower air outlet by utilizing the characteristic that the cold air flow density is large and can naturally sink, the air flows from the air duct to the rear side edge of the shell under the action of the fan system, the air which is refrigerated by the condenser flows from the air duct to the upper air outlet under the action of the fan system, and the cold air is blown out, so that the indoor temperature is reduced. After the air enters the air duct, the air can be blown through the condenser to finish refrigeration under the action of the fan system, the circulating wind direction path of the air in the air conditioner is longer, and the refrigeration of the air conditioner is not good for a user; when heating and hot air supplying in winter, the hot jet flow is not arranged at the upper part of a room due to the hot air floating principle, so that the phenomenon of upper heat and lower cooling occurs, and at the moment, the lower return air temperature is lower than the upper middle part by about 2 ℃, and compared with the upper middle part return air, more energy is required to be consumed to reach the same air outlet temperature, so that the energy-saving effect is poor.
The energy saving, emission reduction and comfort experience of the air conditioner adopting the fixed air supply and return structure under different refrigerating/heating working conditions cannot be simultaneously optimized. Therefore, the traditional single air inlet and outlet circulation mode cannot meet the requirements of refrigerating and heating energy conservation and comfort.
It is highly desirable to achieve a transition from unidirectional circulation to bi-directional reversible circulation in the inlet and outlet air circulation mode. The existing reversible air supply air conditioner has two implementation modes, one is to control the motor of the axial flow fan to realize reversible air supply by arranging the reversible axial flow fan, the mode has high requirements on the manufacturing cost of the motor, and the axial flow fan has the problems of short air supply distance, small air quantity and the like; the other is to arrange a mixed flow fan, and realize reversible air supply through mixed flow fan blades, so that the fan in the mode has high rotating speed, high noise, low working efficiency and unsatisfactory energy-saving effect. The two modes have the problems of large noise, small air quantity and the like, so that the energy conservation and the comfortableness of the air conditioner cannot meet the requirements, and the production cannot be realized.
