Description

A frequency conversion mobile air conditioner

technical field

The utility model relates to the technical field of air conditioners, in particular to a frequency conversion mobile air conditioner.

Background technique

The existing mobile air conditioners are mainly fixed frequency air conditioners, and the corresponding inverter air conditioners are mainly split units. The main reason for this phenomenon is that the electronic control module board on the inverter air conditioner generates a lot of heat, and a corresponding radiator is required to dissipate heat. It is precisely because of the large space of the split type air conditioner that the frequency conversion module can be placed on the outdoor unit, and the work of its outdoor axial flow fan blades helps to take heat away from the radiator.

The mobile air conditioner is mainly used indoors. Due to its compact structure design and small volume, the outdoor air duct is generally designed to be closely attached to the condenser, so there is no space to install the frequency conversion module. Although there are some through to change or The frequency conversion module is installed at the expense of destroying the integrity of the air duct in the air conditioner, but this structural arrangement still reduces the overall air exchange efficiency of the air conditioner to a certain extent.

In addition, the service life of the frequency conversion control module is greatly affected by the ambient temperature, and the noise of the frequency conversion air conditioner is relatively large at high frequencies. Due to the above factors, most air conditioner manufacturers or electrical appliance manufacturers have not implemented frequency conversion mobile air conditioners.
