Problems solved by technology
At present, many buildings are built with architectural grooves for the sake of beauty, and the outside of the grooves is covered by louvers. When multiple air conditioner outdoor units are arranged at the same time in the building groove and the distance between the outdoor units is small, the ventilation of the air conditioner outdoor units will be affected. Due to the narrow space, it becomes unobstructed, and the heat dissipation and operating performance of the outdoor unit will be affected.

Embodiment Construction
[0018] The present invention is described further below:
[0019] 1) Determine the angle φ of the included angle arrangement
[0020] Such as figure 1 As shown, according to the actual installation conditions of the two air-conditioning outdoor units in the groove, the angle φ of the angle arrangement is determined, and the angles of the two outdoor units are 100°, 120°, and 140° in turn. , 160°, 180°.
[0021] 2) Obtain sample data through experimental methods
[0022] The horizontal distance between the two outdoor units obtained from the above analysis was tested sequentially. During the experiment, the distance between the outdoor unit and the wall was controlled at 150mm, the distance between the outdoor unit and the louver was controlled at 250mm, and the height of the groove was 1200mm. The louver spacing is 100mm, the blade width is 50mm, the louver opening is controlled at 10°, and the horizontal distance ds between the two outdoor units is controlled at 50mm. The...

The invention discloses a method for determining the optimal installation angle in included angle arrangement of air-conditioner outdoor units in a groove. The method includes the following specific steps that (1) the angle value range of included angle arrangement is determined to be 100-180 degrees according to the actual installation conditions of included angle arrangement of the two air-conditioner outdoor units in the groove; (2) the return air temperature of each outdoor unit, power consumption of a compressor and refrigerating capacity of an air-conditioning system are obtained according to the included angle arrangement angle value determined in the step (1); and (3) statistic analysis is made based on experimental data in the step (2), so that the optimal installation angle in included angle arrangement of the two air-conditioner outdoor units in the groove is acquired, and the optimal installation angle phi is 140 degrees. Through the optimal installation angle determined by the method, the energy efficiency ratio (EER) of the air-conditioning system can be better increased, and thus the purpose of saving energy is achieved.
Description
technical field [0001] The invention relates to the field of air conditioners, and relates to a method for determining the optimal installation angle of two air conditioner outdoor units arranged at an included angle in a groove. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's requirements for indoor environment are getting higher and higher. As an important means of improving indoor comfort, air conditioning has gradually integrated into our daily life. According to statistics from the National Bureau of Statistics, from 2000 to 2009, the average number of air conditioners owned by every 100 households of urban residents in my country has risen from 30.8 to 106.84 units. In 2016, the sales volume of air conditioners in the domestic market reached more than 47 million units. It can be seen that the domestic household air conditioner usage is increasing year by year.
